GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
|
||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Lesser General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
this service if you wish), that you receive source code or can get it
|
||||
if you want it, that you can change the software or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
source code as you receive it, in any medium, provided that you
|
||||
conspicuously and appropriately publish on each copy an appropriate
|
||||
copyright notice and disclaimer of warranty; keep intact all the
|
||||
notices that refer to this License and to the absence of any warranty;
|
||||
and give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and
|
||||
you may at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion
|
||||
of it, thus forming a work based on the Program, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Program, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, complete source
|
||||
code means all the source code for all modules it contains, plus any
|
||||
associated interface definition files, plus the scripts used to
|
||||
control compilation and installation of the executable. However, as a
|
||||
special exception, the source code distributed need not include
|
||||
anything that is normally distributed (in either source or binary
|
||||
form) with the major components (compiler, kernel, and so on) of the
|
||||
operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering
|
||||
access to copy from a designated place, then offering equivalent
|
||||
access to copy the source code from the same place counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program is
|
||||
void, and will automatically terminate your rights under this License.
|
||||
However, parties who have received copies, or rights, from you under
|
||||
this License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program subject to
|
||||
these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties to
|
||||
this License.
|
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under
|
||||
any particular circumstance, the balance of the section is intended to
|
||||
apply and the section as a whole is intended to apply in other
|
||||
circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system, which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program under this License
|
||||
may add an explicit geographical distribution limitation excluding
|
||||
those countries, so that distribution is permitted only in or among
|
||||
countries not thus excluded. In such case, this License incorporates
|
||||
the limitation as if written in the body of this License.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies a version number of this License which applies to it and "any
|
||||
later version", you have the option of following the terms and conditions
|
||||
either of that version or of any later version published by the Free
|
||||
Software Foundation. If the Program does not specify a version number of
|
||||
this License, you may choose any version ever published by the Free Software
|
||||
Foundation.
|
||||
|
||||
10. If you wish to incorporate parts of the Program into other free
|
||||
programs whose distribution conditions are different, write to the author
|
||||
to ask for permission. For software which is copyrighted by the Free
|
||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||
make exceptions for this. Our decision will be guided by the two goals
|
||||
of preserving the free status of all derivatives of our free software and
|
||||
of promoting the sharing and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||
REPAIR OR CORRECTION.
|
||||
|
||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||
POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest

possible use to the public, the best way to achieve this is to make it
|

free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|

Also add information on how to contact you by electronic and paper mail.
|

If the program is interactive, make it output a short notice like this

when it starts in an interactive mode:

be called something other than `show w' and `show c'; they could even be

mouse-clicks or menu items--whatever suits your program.

|

You should also get your employer (if you work as a programmer) or your

Basically, you can't use the software in a proprietary environment to provide

## Vitastor
|
||||
|
||||
[Read English version](README.md)
|
||||
|
||||
## Идея
|
||||
|
||||
Я всего лишь хочу сделать качественную блочную SDS!
|
||||
|
||||
Vitastor - распределённая блочная SDS, прямой аналог Ceph RBD и внутренних СХД популярных
|
||||
облачных провайдеров. Однако, в отличие от них, Vitastor быстрый и при этом простой.
|
||||
Только пока маленький :-).
|
||||
|
||||
Архитектурная схожесть с Ceph означает заложенную на уровне алгоритмов записи строгую консистентность,
|
||||
репликацию через первичный OSD, симметричную кластеризацию без единой точки отказа
|
||||
и автоматическое распределение данных по любому числу дисков любого размера с настраиваемыми схемами
|
||||
избыточности - репликацией или с произвольными кодами коррекции ошибок.
|
||||
|
||||
## Возможности
|
||||
|
||||
Vitastor на данный момент находится в статусе предварительного выпуска, расширенные
|
||||
возможности пока отсутствуют, а в будущих версиях вероятны "ломающие" изменения.
|
||||
|
||||
Однако следующее уже реализовано:
|
||||
|
||||
- Базовая часть - надёжное кластерное блочное хранилище без единой точки отказа
|
||||
- Производительность ;-D
|
||||
- Несколько схем отказоустойчивости: репликация, XOR n+1 (1 диск чётности), коды коррекции ошибок
|
||||
Рида-Соломона на основе библиотеки jerasure с любым числом дисков данных и чётности в группе
|
||||
- Конфигурация через простые человекочитаемые JSON-структуры в etcd
|
||||
- Автоматическое распределение данных по OSD, с поддержкой:
|
||||
- Математической оптимизации для лучшей равномерности распределения и минимизации перемещений данных
|
||||
- Нескольких пулов с разными схемами избыточности
|
||||
- Дерева распределения, выбора OSD по тегам / классам устройств (только SSD, только HDD) и по поддереву
|
||||
- Настраиваемых доменов отказа (диск/сервер/стойка и т.п.)
|
||||
- Восстановление деградированных блоков
|
||||
- Ребаланс, то есть перемещение данных между OSD (дисками)
|
||||
- Поддержка "ленивого" fsync (fsync не на каждую операцию)
|
||||
- Сбор статистики ввода/вывода в etcd
|
||||
- Клиентская библиотека режима пользователя для ввода/вывода
|
||||
- Драйвер диска для QEMU (собирается вне дерева исходников QEMU)
|
||||
- Драйвер диска для утилиты тестирования производительности fio (также собирается вне дерева исходников fio)
|
||||
- NBD-прокси для монтирования образов ядром ("блочное устройство в режиме пользователя")
|
||||
- Утилита для удаления образов/инодов (vitastor-cli rm-data)
|
||||
- Пакеты для Debian и CentOS
|
||||
- Статистика операций ввода/вывода и занятого места в разрезе инодов
|
||||
- Именование инодов через хранение их метаданных в etcd
|
||||
- Снапшоты и copy-on-write клоны
|
||||
- Сглаживание производительности случайной записи в SSD+HDD конфигурациях
|
||||
- Поддержка RDMA/RoCEv2 через libibverbs
|
||||
- CSI-плагин для Kubernetes
|
||||
- Базовая поддержка OpenStack: драйвер Cinder, патчи для Nova и libvirt
|
||||
- Слияние снапшотов (vitastor-cli {snap-rm,flatten,merge})
|
||||
- Консольный интерфейс для управления образами (vitastor-cli {ls,create,modify})
|
||||
- Плагин для Proxmox
|
||||
|
||||
## Планы развития
|
||||
|
||||
- Поддержка удаления снапшотов (слияния слоёв)
|
||||
- Более корректные скрипты разметки дисков и автоматического запуска OSD
|
||||
- Другие инструменты администрирования
|
||||
- Плагины для OpenNebula и других облачных систем
|
||||
- iSCSI-прокси
|
||||
- Более быстрое переключение при отказах
|
||||
- Фоновая проверка целостности без контрольных сумм (сверка реплик)
|
||||
- Контрольные суммы
|
||||
- Поддержка SSD-кэширования (tiered storage)
|
||||
- Поддержка NVDIMM
|
||||
- Web-интерфейс
|
||||
- Возможно, сжатие
|
||||
- Возможно, поддержка кэширования данных через системный page cache
|
||||
|
||||
## Архитектура
|
||||
|
||||
Так же, как и в Ceph, в Vitastor:
|
||||
|
||||
- Есть пулы (pools), PG, OSD, мониторы, домены отказа, дерево распределения (аналог crush-дерева).
|
||||
- Образы делятся на блоки фиксированного размера (объекты), и эти объекты распределяются по OSD.
|
||||
- У OSD есть журнал и метаданные и они тоже могут размещаться на отдельных быстрых дисках.
|
||||
- Все операции записи тоже транзакционны. В Vitastor, правда, есть режим отложенного/ленивого fsync
|
||||
(коммита), в котором fsync не вызывается на каждую операцию записи, что делает его более
|
||||
пригодным для использования на "плохих" (десктопных) SSD. Однако все операции записи
|
||||
в любом случае атомарны.
|
||||
- Клиентская библиотека тоже старается ждать восстановления после любого отказа кластера, то есть,
|
||||
вы тоже можете перезагрузить хоть весь кластер разом, и клиенты только на время зависнут,
|
||||
но не отключатся.
|
||||
|
||||
Некоторые базовые термины для тех, кто не знаком с Ceph:
|
||||
|
||||
- OSD (Object Storage Daemon) - процесс, который хранит данные на одном диске и обрабатывает
|
||||
запросы чтения/записи от клиентов.
|
||||
- Пул (Pool) - контейнер для данных, имеющих одну и ту же схему избыточности и правила распределения по OSD.
|
||||
- PG (Placement Group) - группа объектов, хранимых на одном и том же наборе реплик (OSD).
|
||||
Несколько PG могут храниться на одном и том же наборе реплик, но объекты одной PG
|
||||
в норме не хранятся на разных наборах OSD.
|
||||
- Монитор - демон, хранящий состояние кластера.
|
||||
- Домен отказа (Failure Domain) - группа OSD, которым вы разрешаете "упасть" всем вместе.
|
||||
Иными словами, это группа OSD, в которые СХД не помещает разные копии одного и того же
|
||||
блока данных. Например, если домен отказа - сервер, то на двух дисках одного сервера
|
||||
никогда не окажется 2 и более копий одного и того же блока данных, а значит, даже
|
||||
если в этом сервере откажут все диски, это будет равносильно потере только 1 копии
|
||||
любого блока данных.
|
||||
- Дерево распределения (Placement Tree / CRUSH Tree) - иерархическая группировка OSD
|
||||
в узлы, которые далее можно использовать как домены отказа. То есть, диск (OSD) входит в
|
||||
сервер, сервер входит в стойку, стойка входит в ряд, ряд в датацентр и т.п.
|
||||
|
||||
Чем Vitastor отличается от Ceph:
|
||||
|
||||
- Vitastor в первую очередь сфокусирован на SSD. Также Vitastor, вероятно, должен неплохо работать
|
||||
с комбинацией SSD и HDD через bcache, а в будущем, возможно, будут добавлены и нативные способы
|
||||
оптимизации под SSD+HDD. Однако хранилище на основе одних лишь жёстких дисков, вообще без SSD,
|
||||
не в приоритете, поэтому оптимизации под этот кейс могут вообще не состояться.
|
||||
- OSD Vitastor однопоточный и всегда таким останется, так как это самый оптимальный способ работы.
|
||||
Если вам не хватает 1 ядра на 1 диск, просто делите диск на разделы и запускайте на нём несколько OSD.
|
||||
Но, скорее всего, вам хватит и 1 ядра - Vitastor не так прожорлив к ресурсам CPU, как Ceph.
|
||||
- Журнал и метаданные всегда размещаются в памяти, благодаря чему никогда не тратится лишнее время
|
||||
на чтение метаданных с диска. Размер метаданных линейно зависит от размера диска и блока данных,
|
||||
который задаётся в конфигурации кластера и по умолчанию составляет 128 КБ. С блоком 128 КБ метаданные
|
||||
занимают примерно 512 МБ памяти на 1 ТБ дискового пространства (и это всё равно меньше, чем нужно Ceph-у).
|
||||
Журнал вообще не должен быть большим, например, тесты производительности в данном документе проводились
|
||||
с журналом размером всего 16 МБ. Большой журнал, вероятно, даже вреден, т.к. "грязные" записи (записи,
|
||||
не сброшенные из журнала) тоже занимают память и могут немного замедлять работу.
|
||||
- В Vitastor нет внутреннего copy-on-write. Я считаю, что реализация CoW-хранилища гораздо сложнее,
|
||||
поэтому сложнее добиться устойчиво хороших результатов. Возможно, в один прекрасный день
|
||||
я придумаю красивый алгоритм для CoW-хранилища, но пока нет - внутреннего CoW в Vitastor не будет.
|
||||
Всё это не относится к "внешнему" CoW (снапшотам и клонам).
|
||||
- Базовый слой Vitastor - простое блочное хранилище с блоками фиксированного размера, а не сложное
|
||||
объектное хранилище с расширенными возможностями, как в Ceph (RADOS).
|
||||
- В Vitastor есть режим "ленивых fsync", в котором OSD группирует запросы записи перед сбросом их
|
||||
на диск, что позволяет получить лучшую производительность с дешёвыми настольными SSD без конденсаторов
|
||||
("Advanced Power Loss Protection" / "Capacitor-Based Power Loss Protection").
|
||||
Тем не менее, такой режим всё равно медленнее использования нормальных серверных SSD и мгновенного
|
||||
fsync, так как приводит к дополнительным операциям передачи данных по сети, поэтому рекомендуется
|
||||
всё-таки использовать хорошие серверные диски, тем более, стоят они почти так же, как десктопные.
|
||||
- PG эфемерны. Это означает, что они не хранятся на дисках и существуют только в памяти работающих OSD.
|
||||
- Процессы восстановления оперируют отдельными объектами, а не целыми PG.
|
||||
- PGLOG-ов нет.
|
||||
- "Мониторы" не хранят данные. Конфигурация и состояние кластера хранятся в etcd в простых человекочитаемых
|
||||
JSON-структурах. Мониторы Vitastor только следят за состоянием кластера и управляют перемещением данных.
|
||||
В этом смысле монитор Vitastor не является критичным компонентом системы и больше похож на Ceph-овский
|
||||
менеджер (MGR). Монитор Vitastor написан на node.js.
|
||||
- Распределение PG не основано на консистентных хешах. Вместо этого все маппинги PG хранятся прямо в etcd
|
||||
(ибо нет никакой проблемы сохранить несколько сотен-тысяч записей в памяти, а не считать каждый раз хеши).
|
||||
Перераспределение PG по OSD выполняется через математическую оптимизацию,
|
||||
а конкретно, сведение задачи к ЛП (задаче линейного программирования) и решение оной с помощью утилиты
|
||||
lp_solve. Такой подход позволяет обычно выравнивать распределение места почти идеально - равномерность
|
||||
обычно составляет 96-99%, в отличие от Ceph, где на голом CRUSH-е без балансировщика обычно выходит 80-90%.
|
||||
Также это позволяет минимизировать объём перемещения данных и случайность связей между OSD, а также менять
|
||||
распределение вручную, не боясь сломать логику перебалансировки. В таком подходе есть и потенциальный
|
||||
недостаток - есть предположение, что в очень большом кластере он может сломаться - однако вплоть до
|
||||
нескольких сотен OSD подход точно работает нормально. Ну и, собственно, при необходимости легко
|
||||
реализовать и консистентные хеши.
|
||||
- Отдельный слой, подобный слою "CRUSH-правил", отсутствует. Вы настраиваете схемы отказоустойчивости,
|
||||
домены отказа и правила выбора OSD напрямую в конфигурации пулов.
|
||||
|
||||
## Понимание сути производительности систем хранения
|
||||
|
||||
Вкратце: для быстрой хранилки задержки важнее, чем пиковые iops-ы.
|
||||
|
||||
Лучшая возможная задержка достигается при тестировании в 1 поток с глубиной очереди 1,
|
||||
что приблизительно означает минимально нагруженное состояние кластера. В данном случае
|
||||
IOPS = 1/задержка. Ни числом серверов, ни дисков, ни серверных процессов/потоков
|
||||
задержка не масштабируется... Она зависит только от того, насколько быстро один
|
||||
серверный процесс (и клиент) обрабатывают одну операцию.
|
||||
|
||||
Почему задержки важны? Потому, что некоторые приложения *не могут* использовать глубину
|
||||
очереди больше 1, ибо их задача не параллелизуется. Важный пример - это все СУБД
|
||||
с поддержкой консистентности (ACID), потому что все они обеспечивают её через
|
||||
журналирование, а журналы пишутся последовательно и с fsync() после каждой операции.
|
||||
|
||||
fsync, кстати - это ещё одна очень важная вещь, про которую почти всегда забывают в тестах.
|
||||
Смысл в том, что все современные диски имеют кэши/буферы записи и не гарантируют, что
|
||||
данные реально физически записываются на носитель до того, как вы делаете fsync(),
|
||||
который транслируется в команду сброса кэша операционной системой.
|
||||
|
||||
Дешёвые SSD для настольных ПК и ноутбуков очень быстрые без fsync - NVMe диски, например,
|
||||
могут обработать порядка 80000 операций записи в секунду с глубиной очереди 1 без fsync.
|
||||
Однако с fsync, когда они реально вынуждены писать каждый блок данных во флеш-память,
|
||||
они выжимают лишь 1000-2000 операций записи в секунду (число практически постоянное
|
||||
для всех моделей SSD).
|
||||
|
||||
Серверные SSD часто имеют суперконденсаторы, работающие как встроенный источник
|
||||
бесперебойного питания и дающие дискам успеть сбросить их DRAM-кэш в постоянную
|
||||
флеш-память при отключении питания. Благодаря этому диски с чистой совестью
|
||||
*игнорируют fsync*, так как точно знают, что данные из кэша доедут до постоянной
|
||||
памяти.
|
||||
|
||||
Все наиболее известные программные СХД, например, Ceph и внутренние СХД, используемые
|
||||
такими облачными провайдерами, как Amazon, Google, Яндекс, медленные в смысле задержки.
|
||||
В лучшем случае они дают задержки от 0.3мс на чтение и 0.6мс на запись 4 КБ блоками
|
||||
даже при условии использования наилучшего возможного железа.
|
||||
|
||||
И это в эпоху SSD, когда вы можете пойти на рынок и купить там SSD, задержка которого
|
||||
на чтение будет 0.1мс, а на запись - 0.04мс, за 100$ или даже дешевле.
|
||||
|
||||
Когда мне нужно быстро протестировать производительность дисковой подсистемы, я
|
||||
использую следующие 6 команд, с небольшими вариациями:
|
||||
|
||||
- Линейная запись:
|
||||
`fio -ioengine=libaio -direct=1 -invalidate=1 -name=test -bs=4M -iodepth=32 -rw=write -runtime=60 -filename=/dev/sdX`
|
||||
- Линейное чтение:
|
||||
`fio -ioengine=libaio -direct=1 -invalidate=1 -name=test -bs=4M -iodepth=32 -rw=read -runtime=60 -filename=/dev/sdX`
|
||||
- Запись в 1 поток (T1Q1):
|
||||
`fio -ioengine=libaio -direct=1 -invalidate=1 -name=test -bs=4k -iodepth=1 -fsync=1 -rw=randwrite -runtime=60 -filename=/dev/sdX`
|
||||
- Чтение в 1 поток (T1Q1):
|
||||
`fio -ioengine=libaio -direct=1 -invalidate=1 -name=test -bs=4k -iodepth=1 -rw=randread -runtime=60 -filename=/dev/sdX`
|
||||
- Параллельная запись (numjobs используется, когда 1 ядро CPU не может насытить диск):
|
||||
`fio -ioengine=libaio -direct=1 -invalidate=1 -name=test -bs=4k -iodepth=128 [-numjobs=4 -group_reporting] -rw=randwrite -runtime=60 -filename=/dev/sdX`
|
||||
- Параллельное чтение (numjobs - аналогично):
|
||||
`fio -ioengine=libaio -direct=1 -invalidate=1 -name=test -bs=4k -iodepth=128 [-numjobs=4 -group_reporting] -rw=randread -runtime=60 -filename=/dev/sdX`
|
||||
|
||||
## Теоретическая максимальная производительность Vitastor
|
||||
|
||||
При использовании репликации:
|
||||
- Задержка чтения в 1 поток (T1Q1): 1 сетевой RTT + 1 чтение с диска.
|
||||
- Запись+fsync в 1 поток:
|
||||
- С мгновенным сбросом: 2 RTT + 1 запись.
|
||||
- С отложенным ("ленивым") сбросом: 4 RTT + 1 запись + 1 fsync.
|
||||
- Параллельное чтение: сумма IOPS всех дисков либо производительность сети, если в сеть упрётся раньше.
|
||||
- Параллельная запись: сумма IOPS всех дисков / число реплик / WA либо производительность сети, если в сеть упрётся раньше.
|
||||
|
||||
При использовании кодов коррекции ошибок (EC):
|
||||
- Задержка чтения в 1 поток (T1Q1): 1.5 RTT + 1 чтение.
|
||||
- Запись+fsync в 1 поток:
|
||||
- С мгновенным сбросом: 3.5 RTT + 1 чтение + 2 записи.
|
||||
- С отложенным ("ленивым") сбросом: 5.5 RTT + 1 чтение + 2 записи + 2 fsync.
|
||||
- Под 0.5 на самом деле подразумевается (k-1)/k, где k - число дисков данных,
|
||||
что означает, что дополнительное обращение по сети не нужно, когда операция
|
||||
чтения обслуживается локально.
|
||||
- Параллельное чтение: сумма IOPS всех дисков либо производительность сети, если в сеть упрётся раньше.
|
||||
- Параллельная запись: сумма IOPS всех дисков / общее число дисков данных и чётности / WA либо производительность сети, если в сеть упрётся раньше.
|
||||
Примечание: IOPS дисков в данном случае надо брать в смешанном режиме чтения/записи в пропорции, аналогичной формулам выше.
|
||||
|
||||
WA (мультипликатор записи) для 4 КБ блоков в Vitastor обычно составляет 3-5:
|
||||
1. Запись метаданных в журнал
|
||||
2. Запись блока данных в журнал
|
||||
3. Запись метаданных в БД
|
||||
4. Ещё одна запись метаданных в журнал при использовании EC
|
||||
5. Запись блока данных на диск данных
|
||||
|
||||
Если вы найдёте SSD, хорошо работающий с 512-байтными блоками данных (Optane?),
|
||||
то 1, 3 и 4 можно снизить до 512 байт (1/8 от размера данных) и получить WA всего 2.375.
|
||||
|
||||
Кроме того, WA снижается при использовании отложенного/ленивого сброса при параллельной
|
||||
нагрузке, т.к. блоки журнала записываются на диск только когда они заполняются или явным
|
||||
образом запрашивается fsync.
|
||||
|
||||
## Пример сравнения с Ceph
|
||||
|
||||
Железо - 4 сервера, в каждом:
|
||||
- 6x SATA SSD Intel D3-4510 3.84 TB
|
||||
- 2x Xeon Gold 6242 (16 cores @ 2.8 GHz)
|
||||
- 384 GB RAM
|
||||
- 1x 25 GbE сетевая карта (Mellanox ConnectX-4 LX), подключённая к свитчу Juniper QFX5200
|
||||
|
||||
Экономия энергии CPU отключена. В тестах и Vitastor, и Ceph развёрнуто по 2 OSD на 1 SSD.
|
||||
|
||||
Все результаты ниже относятся к случайной нагрузке 4 КБ блоками (если явно не указано обратное).
|
||||
|
||||
Производительность голых дисков:
|
||||
- T1Q1 запись ~27000 iops (задержка ~0.037ms)
|
||||
- T1Q1 чтение ~9800 iops (задержка ~0.101ms)
|
||||
- T1Q32 запись ~60000 iops
|
||||
- T1Q32 чтение ~81700 iops
|
||||
|
||||
Ceph 15.2.4 (Bluestore):
|
||||
- T1Q1 запись ~1000 iops (задержка ~1ms)
|
||||
- T1Q1 чтение ~1750 iops (задержка ~0.57ms)
|
||||
- T8Q64 запись ~100000 iops, потребление CPU процессами OSD около 40 ядер на каждом сервере
|
||||
- T8Q64 чтение ~480000 iops, потребление CPU процессами OSD около 40 ядер на каждом сервере
|
||||
|
||||
Тесты в 8 потоков проводились на 8 400GB RBD образах со всех хостов (с каждого хоста запускалось 2 процесса fio).
|
||||
Это нужно потому, что в Ceph несколько RBD-клиентов, пишущих в 1 образ, очень сильно замедляются.
|
||||
|
||||
Настройки RocksDB и Bluestore в Ceph не менялись, единственным изменением было отключение cephx_sign_messages.
|
||||
|
||||
На самом деле, результаты теста не такие уж и плохие для Ceph (могло быть хуже).
|
||||
Собственно говоря, эти серверы как раз хорошо сбалансированы для Ceph - 6 SATA SSD как раз
|
||||
утилизируют 25-гигабитную сеть, а без 2 мощных процессоров Ceph-у бы не хватило ядер,
|
||||
чтобы выдать пристойный результат. Собственно, что и показывает жор 40 ядер в процессе
|
||||
параллельного теста.
|
||||
|
||||
Vitastor:
|
||||
- T1Q1 запись: 7087 iops (задержка 0.14ms)
|
||||
- T1Q1 чтение: 6838 iops (задержка 0.145ms)
|
||||
- T2Q64 запись: 162000 iops, потребление CPU - 3 ядра на каждом сервере
|
||||
- T8Q64 чтение: 895000 iops, потребление CPU - 4 ядра на каждом сервере
|
||||
- Линейная запись (4M T1Q32): 2800 МБ/с
|
||||
- Линейное чтение (4M T1Q32): 1500 МБ/с
|
||||
|
||||
Тест на чтение в 8 потоков проводился на 1 большом образе (3.2 ТБ) со всех хостов (опять же, по 2 fio с каждого).
|
||||
В Vitastor никакой разницы между 1 образом и 8-ю нет. Естественно, примерно 1/4 запросов чтения
|
||||
в такой конфигурации, как и в тестах Ceph выше, обслуживалась с локальной машины. Если проводить
|
||||
тест так, чтобы все операции всегда обращались к первичным OSD по сети - тест сильнее упирался
|
||||
в сеть и результат составлял примерно 689000 iops.
|
||||
|
||||
Настройки Vitastor: `--disable_data_fsync true --immediate_commit all --flusher_count 8
|
||||
--disk_alignment 4096 --journal_block_size 4096 --meta_block_size 4096
|
||||
--journal_no_same_sector_overwrites true --journal_sector_buffer_count 1024
|
||||
--journal_size 16777216`.
|
||||
|
||||
### EC/XOR 2+1
|
||||
|
||||
Vitastor:
|
||||
- T1Q1 запись: 2808 iops (задержка ~0.355ms)
|
||||
- T1Q1 чтение: 6190 iops (задержка ~0.16ms)
|
||||
- T2Q64 запись: 85500 iops, потребление CPU - 3.4 ядра на каждом сервере
|
||||
- T8Q64 чтение: 812000 iops, потребление CPU - 4.7 ядра на каждом сервере
|
||||
- Линейная запись (4M T1Q32): 3200 МБ/с
|

### NBD
|
||||
|
||||
NBD расшифровывается как "сетевое блочное устройство", но на самом деле оно также
|
||||
работает просто как аналог FUSE для блочных устройств, то есть, представляет собой
|
||||
"блочное устройство в пространстве пользователя".
|
||||
|
||||
NBD - на данный момент единственный способ монтировать Vitastor ядром Linux.
|
||||
NBD немного снижает производительность, так как приводит к дополнительным копированиям
|
||||
данных между ядром и пространством пользователя. Тем не менее, способ достаточно оптимален,
|
||||
а производительность случайного доступа вообще затрагивается слабо.
|
||||
|
||||
Vitastor с однопоточной NBD прокси на том же стенде:
|
||||
- T1Q1 запись: 6000 iops (задержка 0.166ms)
|
||||
- T1Q1 чтение: 5518 iops (задержка 0.18ms)
|
||||
- T1Q128 запись: 94400 iops
|
||||
- T1Q128 чтение: 103000 iops
|
||||
- Линейная запись (4M T1Q128): 1266 МБ/с (в сравнении с 2800 МБ/с через fio)
|
||||
- Линейное чтение (4M T1Q128): 975 МБ/с (в сравнении с 1500 МБ/с через fio)
|
||||
|
||||
## Установка
|
||||
|
||||
### Debian
|
||||
|
||||
- Добавьте ключ репозитория Vitastor:
|
||||
`wget -q -O - https://vitastor.io/debian/pubkey | sudo apt-key add -`
|
||||
- Добавьте репозиторий Vitastor в /etc/apt/sources.list:
|
||||
- Debian 11 (Bullseye/Sid): `deb https://vitastor.io/debian bullseye main`
|
||||
- Debian 10 (Buster): `deb https://vitastor.io/debian buster main`
|
||||
- Для Debian 10 (Buster) также включите репозиторий backports:
|
||||
`deb http://deb.debian.org/debian buster-backports main`
|
||||
- Установите пакеты: `apt update; apt install vitastor lp-solve etcd linux-image-amd64 qemu`
|
||||
|
||||
### CentOS
|
||||
|
||||
- Добавьте в систему репозиторий Vitastor:
|
||||
- CentOS 7: `yum install https://vitastor.io/rpms/centos/7/vitastor-release-1.0-1.el7.noarch.rpm`
|
||||
- CentOS 8: `dnf install https://vitastor.io/rpms/centos/8/vitastor-release-1.0-1.el8.noarch.rpm`
|
||||
- Включите EPEL: `yum/dnf install epel-release`
|
||||
- Включите дополнительные репозитории CentOS:
|
||||
- CentOS 7: `yum install centos-release-scl`
|
||||
- CentOS 8: `dnf install centos-release-advanced-virtualization`
|
||||
- Включите elrepo-kernel:
|
||||
- CentOS 7: `yum install https://www.elrepo.org/elrepo-release-7.el7.elrepo.noarch.rpm`
|
||||
- CentOS 8: `dnf install https://www.elrepo.org/elrepo-release-8.el8.elrepo.noarch.rpm`
|
||||
- Установите пакеты: `yum/dnf install vitastor lpsolve etcd kernel-ml qemu-kvm`
|
||||
|
||||
### Установка из исходников
|
||||
|
||||
- Установите ядро 5.4 или более новое, для поддержки io_uring. Желательно 5.8 или даже новее,
|
||||
так как в 5.4 есть как минимум 1 известный баг, ведущий к зависанию с io_uring и контроллером HP SmartArray.
|
||||
- Установите liburing 0.4 или более новый и его заголовки.
|
||||
- Установите lp_solve.
|
||||
- Установите etcd, версии не ниже 3.4.15. Более ранние версии работать не будут из-за различных багов,
|
||||
например [#12402](https://github.com/etcd-io/etcd/pull/12402). Также вы можете взять версию 3.4.13 с
|
||||
этим конкретным исправлением из ветки release-3.4 репозитория https://github.com/vitalif/etcd/.
|
||||
- Установите node.js 10 или новее.
|
||||
- Установите gcc и g++ 8.x или новее.
|
||||
- Склонируйте данный репозиторий с подмодулями: `git clone https://yourcmc.ru/git/vitalif/vitastor/`.
|
||||
- Желательно пересобрать QEMU с патчем, который делает необязательным запуск через LD_PRELOAD.
|
||||
См `patches/qemu-*.*-vitastor.patch` - выберите версию, наиболее близкую вашей версии QEMU.
|
||||
- Установите QEMU 3.0 или новее, возьмите исходные коды установленного пакета, начните его пересборку,
|
||||
через некоторое время остановите её и скопируйте следующие заголовки:
|
||||
- `<qemu>/include` → `<vitastor>/qemu/include`
|
||||
- Debian:
|
||||
* Берите qemu из основного репозитория
|
||||
* `<qemu>/b/qemu/config-host.h` → `<vitastor>/qemu/b/qemu/config-host.h`
|
||||
* `<qemu>/b/qemu/qapi` → `<vitastor>/qemu/b/qemu/qapi`
|
||||
- CentOS 8:
|
||||
* Берите qemu из репозитория Advanced-Virtualization. Чтобы включить его, запустите
|
||||
`yum install centos-release-advanced-virtualization.noarch` и далее `yum install qemu`
|
||||
* `<qemu>/config-host.h` → `<vitastor>/qemu/b/qemu/config-host.h`
|
||||
* Для QEMU 3.0+: `<qemu>/qapi` → `<vitastor>/qemu/b/qemu/qapi`
|
||||
* Для QEMU 2.0+: `<qemu>/qapi-types.h` → `<vitastor>/qemu/b/qemu/qapi-types.h`
|
||||
- `config-host.h` и `qapi` нужны, т.к. в них содержатся автогенерируемые заголовки
|
||||
- Установите fio 3.7 или новее, возьмите исходники пакета и сделайте на них симлинк с `<vitastor>/fio`.
|
||||
- Соберите и установите Vitastor командой `mkdir build && cd build && cmake .. && make -j8 && make install`.
|
||||
Обратите внимание на переменную cmake `QEMU_PLUGINDIR` - под RHEL её нужно установить равной `qemu-kvm`.
|
||||
|
||||
## Запуск
|
||||
|
||||
Внимание: процедура пока что достаточно нетривиальная, задавать конфигурацию и смещения
|
||||
на диске нужно почти вручную. Это будет исправлено в ближайшем будущем.
|
||||
|
||||
- Желательны SATA SSD или NVMe диски с конденсаторами (серверные SSD). Можно использовать и
|
||||
десктопные SSD, включив режим отложенного fsync, но производительность однопоточной записи
|
||||
в этом случае пострадает.
|
||||
- Быстрая сеть, минимум 10 гбит/с
|
||||
- Для наилучшей производительности нужно отключить энергосбережение CPU: `cpupower idle-set -D 0 && cpupower frequency-set -g performance`.
|
||||
- На хостах мониторов:
|
||||
- Пропишите нужные вам значения в файле `/usr/lib/vitastor/mon/make-units.sh`
|
||||
- Создайте юниты systemd для etcd и мониторов: `/usr/lib/vitastor/mon/make-units.sh`
|
||||
- Пропишите etcd_address и osd_network в `/etc/vitastor/vitastor.conf`. Например:
|
||||
```
|
||||
{
|
||||
"etcd_address": ["10.200.1.10:2379","10.200.1.11:2379","10.200.1.12:2379"],
|
||||
"osd_network": "10.200.1.0/24"
|
||||
}
|
||||
```
|
||||
- Создайте юниты systemd для OSD: `/usr/lib/vitastor/make-osd.sh /dev/disk/by-partuuid/XXX [/dev/disk/by-partuuid/YYY ...]`
|
||||
- Вы можете менять параметры OSD в юнитах systemd или в `vitastor.conf`. Смысл некоторых параметров:
|
||||
- `disable_data_fsync 1` - отключает fsync, используется с SSD с конденсаторами.
|
||||
- `immediate_commit all` - используется с SSD с конденсаторами.
|
||||
Внимание: если установлено, также нужно установить его в то же значение в etcd в /vitastor/config/global
|
||||
- `disable_device_lock 1` - отключает блокировку файла устройства, нужно, только если вы запускаете
|
||||
несколько OSD на одном блочном устройстве.
|
||||
- `flusher_count 256` - "flusher" - микропоток, удаляющий старые данные из журнала.
|
||||
Не волнуйтесь об этой настройке, 256 теперь достаточно практически всегда.
|
||||
- `disk_alignment`, `journal_block_size`, `meta_block_size` следует установить равными размеру
|
||||
внутреннего блока SSD. Это почти всегда 4096.
|
||||
- `journal_no_same_sector_overwrites true` запрещает перезапись одного и того же сектора журнала подряд
|
||||
много раз в процессе записи. Большинство (99%) SSD не нуждаются в данной опции. Однако выяснилось, что
|
||||
диски, используемые на одном из тестовых стендов - Intel D3-S4510 - очень сильно не любят такую
|
||||
перезапись, и для них была добавлена эта опция. Когда данный режим включён, также нужно поднимать
|
||||
значение `journal_sector_buffer_count`, так как иначе Vitastor не хватит буферов для записи в журнал.
|
||||
- Запустите все etcd: `systemctl start etcd`
|
||||
- Создайте глобальную конфигурацию в etcd: `etcdctl --endpoints=... put /vitastor/config/global '{"immediate_commit":"all"}'`
|
||||
(если все ваши диски - серверные с конденсаторами).
|
||||
- Создайте пулы: `etcdctl --endpoints=... put /vitastor/config/pools '{"1":{"name":"testpool","scheme":"replicated","pg_size":2,"pg_minsize":1,"pg_count":256,"failure_domain":"host"}}'`.
|
||||
Для jerasure EC-пулов конфигурация должна выглядеть так: `2:{"name":"ecpool","scheme":"jerasure","pg_size":4,"parity_chunks":2,"pg_minsize":2,"pg_count":256,"failure_domain":"host"}`.
|
||||
- Запустите все OSD: `systemctl start vitastor.target`
|
||||
- Ваш кластер должен быть готов - один из мониторов должен уже сконфигурировать PG, а OSD должны запустить их.
|
||||
- Вы можете проверить состояние PG прямо в etcd: `etcdctl --endpoints=... get --prefix /vitastor/pg/state`. Все PG должны быть 'active'.
|
||||
|
||||
### Задать имя образу
|
||||
|
||||
```
|
||||
etcdctl --endpoints=<etcd> put /vitastor/config/inode/<pool>/<inode> '{"name":"<name>","size":<size>[,"parent_id":<parent_inode_number>][,"readonly":true]}'
|
||||
```
|
||||
|
||||
Например:
|
||||
|
||||
```
|
||||
etcdctl --endpoints=http://10.115.0.10:2379/v3 put /vitastor/config/inode/1/1 '{"name":"testimg","size":2147483648}'
|
||||
```
|
||||
|
||||
Если вы зададите parent_id, то образ станет CoW-клоном, т.е. все новые запросы записи пойдут в новый инод, а запросы
|
||||
чтения будут проверять сначала его, а потом родительские слои по цепочке вверх. Чтобы случайно не перезаписать данные
|
||||
в родительском слое, вы можете переключить его в режим "только чтение", добавив флаг `"readonly":true` в его запись
|
||||
метаданных. В таком случае родительский образ становится просто снапшотом.
|
||||
|
||||
Таким образом, для создания снапшота вам нужно просто переименовать предыдущий inode (например, из testimg в testimg@0),
|
||||
сделать его readonly и создать новый слой с исходным именем образа (testimg), ссылающийся на только что переименованный
|
||||
в качестве родительского.
|
||||
|
||||
### Запуск тестов с fio
|
||||
|
||||
Пример команды для запуска тестов:
|
||||
|
||||
```
|
||||
fio -thread -ioengine=libfio_vitastor.so -name=test -bs=4M -direct=1 -iodepth=16 -rw=write -etcd=10.115.0.10:2379/v3 -image=testimg
|
||||
```
|
||||
|
||||
Если вы не хотите обращаться к образу по имени, вместо `-image=testimg` можно указать номер пула, номер инода и размер:
|
||||
`-pool=1 -inode=1 -size=400G`.
|
||||
|
||||
### Загрузить образ диска ВМ в/из Vitastor
|
||||
|
||||
Используйте qemu-img и строку `vitastor:etcd_host=<HOST>:image=<IMAGE>` в качестве имени файла диска. Например:
|
||||
|
||||
```
|
||||
qemu-img convert -f qcow2 debian10.qcow2 -p -O raw 'vitastor:etcd_host=10.115.0.10\:2379/v3:image=testimg'
|
||||
```
|
||||
|
||||
Обратите внимание, что если вы используете немодифицированный QEMU, потребуется установить переменную окружения
|
||||
`LD_PRELOAD=/usr/lib/x86_64-linux-gnu/qemu/block-vitastor.so`.
|
||||
|
||||
Если вы не хотите обращаться к образу по имени, вместо `:image=<IMAGE>` можно указать номер пула, номер инода и размер:
|
||||
`:pool=<POOL>:inode=<INODE>:size=<SIZE>`.
|
||||
|
||||
### Запустить ВМ
|
||||
|
||||
Для запуска QEMU используйте опцию `-drive file=vitastor:etcd_host=<HOST>:image=<IMAGE>` (аналогично qemu-img)
|
||||
и физический размер блока 4 KB.
|
||||
|
||||
Например:
|
||||
|
||||
```
|
||||
qemu-system-x86_64 -enable-kvm -m 1024
|
||||
-drive 'file=vitastor:etcd_host=10.115.0.10\:2379/v3:image=testimg',format=raw,if=none,id=drive-virtio-disk0,cache=none
|
||||
-device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x5,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1,write-cache=off,physical_block_size=4096,logical_block_size=512
|
||||
-vnc 0.0.0.0:0
|
||||
```
|
||||
|
||||
Обращение по номерам (`:pool=<POOL>:inode=<INODE>:size=<SIZE>` вместо `:image=<IMAGE>`) работает аналогично qemu-img.
|
||||
|
||||
### Удалить образ
|
||||
|
||||
Используйте утилиту vitastor-cli rm-data. Например:
|
||||
|
||||
```
|
||||
vitastor-cli rm-data --etcd_address 10.115.0.10:2379/v3 --pool 1 --inode 1 --parallel_osds 16 --iodepth 32
|
||||
```
|
||||
|
||||
### NBD
|
||||
|
||||
Чтобы создать локальное блочное устройство, используйте NBD. Например:
|
||||
|
||||
```
|
||||
vitastor-nbd map --etcd_address 10.115.0.10:2379/v3 --image testimg
|
||||
```
|
||||
|
||||
Команда напечатает название устройства вида /dev/nbd0, которое потом можно будет форматировать
|
||||
и использовать как обычное блочное устройство.
|
||||
|
||||
Для обращения по номеру инода, аналогично другим командам, можно использовать опции
|
||||
`--pool <POOL> --inode <INODE> --size <SIZE>` вместо `--image testimg`.
|
||||
|
||||
### Kubernetes
|
||||
|
||||
У Vitastor есть CSI-плагин для Kubernetes, поддерживающий RWO-тома.
|
||||
|
||||
Для установки возьмите манифесты из директории [csi/deploy/](csi/deploy/), поместите
|
||||
вашу конфигурацию подключения к Vitastor в [csi/deploy/001-csi-config-map.yaml](001-csi-config-map.yaml),
|
||||
настройте StorageClass в [csi/deploy/009-storage-class.yaml](009-storage-class.yaml)
|
||||
и примените все `NNN-*.yaml` к вашей инсталляции Kubernetes.
|
||||
|
||||
```
|
||||
for i in ./???-*.yaml; do kubectl apply -f $i; done
|
||||
```
|
||||
|
||||
После этого вы сможете создавать PersistentVolume. Пример смотрите в файле [csi/deploy/example-pvc.yaml](csi/deploy/example-pvc.yaml).
|
||||
|
||||
### OpenStack
|
||||
|
||||
Чтобы подключить Vitastor к OpenStack:
|
||||
|
||||
- Установите пакеты vitastor-client, libvirt и QEMU из DEB или RPM репозитория Vitastor
|
||||
- Примените патч `patches/nova-21.diff` или `patches/nova-23.diff` к вашей инсталляции Nova.
|
||||
nova-21.diff подходит для Nova 21-22, nova-23.diff подходит для Nova 23-24.
|
||||
- Скопируйте `patches/cinder-vitastor.py` в инсталляцию Cinder как `cinder/volume/drivers/vitastor.py`
|
||||
- Создайте тип томов в cinder.conf (см. ниже)
|
||||
- Обязательно заблокируйте доступ от виртуальных машин к сети Vitastor (OSD и etcd), т.к. Vitastor (пока) не поддерживает аутентификацию
|
||||
- Перезапустите Cinder и Nova
|
||||
|
||||
Пример конфигурации Cinder:
|
||||
|
||||
```
|
||||
[DEFAULT]
|
||||
enabled_backends = lvmdriver-1, vitastor-testcluster
|
||||
# ...
|
||||
|
||||
[vitastor-testcluster]
|
||||
volume_driver = cinder.volume.drivers.vitastor.VitastorDriver
|
||||
volume_backend_name = vitastor-testcluster
|
||||
image_volume_cache_enabled = True
|
||||
volume_clear = none
|
||||
vitastor_etcd_address = 192.168.7.2:2379
|
||||
vitastor_etcd_prefix =
|
||||
vitastor_config_path = /etc/vitastor/vitastor.conf
|
||||
vitastor_pool_id = 1
|
||||
image_upload_use_cinder_backend = True
|
||||
```
|
||||
|
||||
Чтобы помещать в Vitastor Glance-образы, нужно использовать
|
||||
[https://docs.openstack.org/cinder/pike/admin/blockstorage-volume-backed-image.html](образы на основе томов Cinder),
|
||||
однако, поддержка этой функции ещё не проверялась.
|
||||
|
||||
### Proxmox
|
||||
|
||||
Чтобы подключить Vitastor к Proxmox Virtual Environment (поддерживаются версии 6.4 и 7.1):
|
||||
|
||||
- Добавьте соответствующий Debian-репозиторий Vitastor в sources.list на хостах Proxmox
|
||||
(buster для 6.4, bullseye для 7.1)
|
||||
- Установите пакеты vitastor-client, pve-qemu-kvm, pve-storage-vitastor (* или см. сноску) из репозитория Vitastor
|
||||
- Определите тип хранилища в `/etc/pve/storage.cfg` (см. ниже)
|
||||
- Обязательно заблокируйте доступ от виртуальных машин к сети Vitastor (OSD и etcd), т.к. Vitastor (пока) не поддерживает аутентификацию
|
||||
- Перезапустите демон Proxmox: `systemctl restart pvedaemon`
|
||||
|
||||
Пример `/etc/pve/storage.cfg` (единственная обязательная опция - vitastor_pool, все остальные
|
||||
перечислены внизу для понимания значений по умолчанию):
|
||||
|
||||
```
|
||||
vitastor: vitastor
|
||||
# Пул, в который будут помещаться образы дисков
|
||||
vitastor_pool testpool
|
||||
# Путь к файлу конфигурации
|
||||
vitastor_config_path /etc/vitastor/vitastor.conf
|
||||
# Адрес(а) etcd, нужны, только если не указаны в vitastor.conf
|
||||
vitastor_etcd_address 192.168.7.2:2379/v3
|
||||
# Префикс ключей метаданных в etcd
|
||||
vitastor_etcd_prefix /vitastor
|
||||
# Префикс имён образов
|
||||
vitastor_prefix pve/
|
||||
# Монтировать образы через NBD прокси, через ядро (нужно только для контейнеров)
|
||||
vitastor_nbd 0
|
||||
```
|
||||
|
||||
\* Примечание: вместо установки пакета pve-storage-vitastor вы можете вручную скопировать файл
|
||||
[patches/PVE_VitastorPlugin.pm](patches/PVE_VitastorPlugin.pm) на хосты Proxmox как
|
||||
`/usr/share/perl5/PVE/Storage/Custom/VitastorPlugin.pm`.
|
||||
|
||||
## Известные проблемы
|
||||
|
||||
- Запросы удаления объектов могут в данный момент приводить к "неполным" объектам в EC-пулах,
|
||||
если в процессе удаления произойдут отказы OSD или серверов, потому что правильная обработка
|
||||
запросов удаления в кластере должна быть "трёхфазной", а это пока не реализовано. Если вы
|
||||
столкнётесь с такой ситуацией, просто повторите запрос удаления.
|
||||
|
||||
## Принципы реализации
|
||||
|
||||
- Я люблю архитектурно простые решения. Vitastor проектируется именно так и я намерен
|
||||
и далее следовать данному принципу.
|
||||
- Если вы пришли сюда за идеальным кодом на C++, вы, вероятно, не по адресу. "Общепринятые"
|
||||
практики написания C++ кода меня не очень волнуют, так как зачастую, опять-таки, ведут к
|
||||
излишним усложнениям и код получается красивый... но медленный.
|
||||
- По той же причине в коде иногда можно встретить велосипеды типа собственного упрощённого
|
||||
HTTP-клиента для работы с etcd. Зато эти велосипеды маленькие и компактные и не требуют
|
||||
использования десятка внешних библиотек.
|
||||
- node.js для монитора - не случайный выбор. Он очень быстрый, имеет встроенную событийную
|
||||
машину, приятный нейтральный C-подобный язык программирования и развитую инфраструктуру.

VNPL - "сетевой копилефт", собственная свободная копилефт-лицензия
|
||||
Vitastor Network Public License 1.1, основанная на GNU GPL 3.0 с дополнительным
|
||||
условием "Сетевого взаимодействия", требующим распространять все программы,
|
||||
специально разработанные для использования вместе с Vitastor и взаимодействующие
|
||||
с ним по сети, под лицензией VNPL или под любой другой свободной лицензией.
|
||||
|
||||
Идея VNPL - расширение действия копилефта не только на модули, явным образом
|
||||
связываемые с кодом Vitastor, но также на модули, оформленные в виде микросервисов
|
||||
и взаимодействующие с ним по сети.
|
||||
|
||||
Таким образом, если вы хотите построить на основе Vitastor сервис, содержаший
|
||||
компоненты с закрытым кодом, взаимодействующие с Vitastor, вам нужна коммерческая
|
||||
лицензия от автора 😀.
|
||||
|
||||
На Windows и любое другое ПО, не разработанное *специально* для использования
|
||||
вместе с Vitastor, никакие ограничения не накладываются.
|
||||
|
||||
Клиентские библиотеки распространяются на условиях двойной лицензии VNPL 1.0
|
||||
и также на условиях GNU GPL 2.0 или более поздней версии. Так сделано в целях
|
||||
совместимости с таким ПО, как QEMU и fio.

## Vitastor
|
||||
|
||||
[Читать на русском](README-ru.md)
|
||||
|
||||
## The Idea
|
||||
|
||||
Make Software-Defined Block Storage Great Again.
|
||||
|
||||
Vitastor is a small, simple and fast clustered block storage (storage for VM drives),
|
||||
architecturally similar to Ceph which means strong consistency, primary-replication, symmetric
|
||||
clustering and automatic data distribution over any number of drives of any size
|
||||
with configurable redundancy (replication or erasure codes/XOR).
|
||||
|
||||
## Features
|
||||
|
||||
Vitastor is currently a pre-release, a lot of features are missing and you can still expect
|
||||
breaking changes in the future. However, the following is implemented:
|
||||
|
||||
- Basic part: highly-available block storage with symmetric clustering and no SPOF
|
||||
- Performance ;-D
|
||||
- Multiple redundancy schemes: Replication, XOR n+1, Reed-Solomon erasure codes
|
||||
based on jerasure library with any number of data and parity drives in a group
|
||||
- Configuration via simple JSON data structures in etcd
|
||||
- Automatic data distribution over OSDs, with support for:
|
||||
- Mathematical optimization for better uniformity and less data movement
|
||||
- Multiple pools
|
||||
- Placement tree, OSD selection by tags (device classes) and placement root
|
||||
- Configurable failure domains
|
||||
- Recovery of degraded blocks
|
||||
- Rebalancing (data movement between OSDs)
|
||||
- Lazy fsync support
|
||||
- I/O statistics reporting to etcd
|
||||
- Generic user-space client library
|
||||
- QEMU driver (built out-of-tree)
|
||||
- Loadable fio engine for benchmarks (also built out-of-tree)
|
||||
- NBD proxy for kernel mounts
|
||||
- Inode removal tool (vitastor-cli rm-data)
|
||||
- Packaging for Debian and CentOS
|
||||
- Per-inode I/O and space usage statistics
|
||||
- Inode metadata storage in etcd
|
||||
- Snapshots and copy-on-write image clones
|
||||
- Write throttling to smooth random write workloads in SSD+HDD configurations
|
||||
- RDMA/RoCEv2 support via libibverbs
|
||||
- CSI plugin for Kubernetes
|
||||
- Basic OpenStack support: Cinder driver, Nova and libvirt patches
|
||||
- Snapshot merge tool (vitastor-cli {snap-rm,flatten,merge})
|
||||
- Image management CLI (vitastor-cli {ls,create,modify})
|
||||
- Proxmox storage plugin
|
||||
|
||||
## Roadmap
|
||||
|
||||
- Snapshot deletion (layer merge) support
|
||||
- Better OSD creation and auto-start tools
|
||||
- Other administrative tools
|
||||
- Plugins for OpenNebula, Proxmox and other cloud systems
|
||||
- iSCSI proxy
|
||||
- Faster failover
|
||||
- Scrubbing without checksums (verification of replicas)
|
||||
- Checksums
|
||||
- Tiered storage
|
||||
- NVDIMM support
|
||||
- Web GUI
|
||||
- Compression (possibly)
|
||||
- Read caching using system page cache (possibly)
|
||||
|
||||
## Architecture
|
||||
|
||||
Similarities:
|
||||
|
||||
- Just like Ceph, Vitastor has Pools, PGs, OSDs, Monitors, Failure Domains, Placement Tree.
|
||||
- Just like Ceph, Vitastor is transactional (even though there's a "lazy fsync mode" which
|
||||
doesn't implicitly flush every operation to disks).
|
||||
- OSDs also have journal and metadata and they can also be put on separate drives.
|
||||
- Just like in Ceph, client library attempts to recover from any cluster failure so
|
||||
you can basically reboot the whole cluster and only pause, but not crash, your clients
|
||||
(I consider this a bug if the client crashes in that case).
|
||||
|
||||
Some basic terms for people not familiar with Ceph:
|
||||
|
||||
- OSD (Object Storage Daemon) is a process that stores data and serves read/write requests.
|
||||
- PG (Placement Group) is a container for data that (normally) shares the same replicas.
|
||||
- Pool is a container for data that has the same redundancy scheme and placement rules.
|
||||
- Monitor is a separate daemon that watches cluster state and handles failures.
|
||||
- Failure Domain is a group of OSDs that you allow to fail. It's "host" by default.
|
||||
- Placement Tree groups OSDs in a hierarchy to later split them into Failure Domains.
|
||||
|
||||
Architectural differences from Ceph:
|
||||
|
||||
- Vitastor's primary focus is on SSDs. Proper SSD+HDD optimizations may be added in the future, though.
|
||||
- Vitastor OSD is (and will always be) single-threaded. If you want to dedicate more than 1 core
|
||||
per drive you should run multiple OSDs each on a different partition of the drive.
|
||||
Vitastor isn't CPU-hungry though (as opposed to Ceph), so 1 core is sufficient in a lot of cases.
|
||||
- Metadata and journal are always kept in memory. Metadata size depends linearly on drive capacity
|
||||
and data store block size which is 128 KB by default. With 128 KB blocks metadata should occupy
|
||||
around 512 MB per 1 TB (which is still less than Ceph wants). Journal doesn't have to be big,
|
||||
the example test below was conducted with only 16 MB journal. A big journal is probably even
|
||||
harmful as dirty write metadata also take some memory.
|
||||
- Vitastor storage layer doesn't have internal copy-on-write or redirect-write. I know that maybe
|
||||
it's possible to create a good copy-on-write storage, but it's much harder and makes performance
|
||||
less deterministic, so CoW isn't used in Vitastor.
|
||||
- The basic layer of Vitastor is block storage with fixed-size blocks, not object storage with
|
||||
rich semantics like in Ceph (RADOS).
|
||||
- There's a "lazy fsync" mode which allows to batch writes before flushing them to the disk.
|
||||
This allows to use Vitastor with desktop SSDs, but still lowers performance due to additional
|
||||
network roundtrips, so use server SSDs with capacitor-based power loss protection
|
||||
("Advanced Power Loss Protection") for best performance.
|
||||
- PGs are ephemeral. This means that they aren't stored on data disks and only exist in memory
|
||||
while OSDs are running.
|
||||
- Recovery process is per-object (per-block), not per-PG. Also there are no PGLOGs.
|
||||
- Monitors don't store data. Cluster configuration and state is stored in etcd in simple human-readable
|
||||
JSON structures. Monitors only watch cluster state and handle data movement.
|
||||
Thus Vitastor's Monitor isn't a critical component of the system and is more similar to Ceph's Manager.
|
||||
Vitastor's Monitor is implemented in node.js.
|
||||
- PG distribution isn't based on consistent hashes. All PG mappings are stored in etcd.
|
||||
Rebalancing PGs between OSDs is done by mathematical optimization - data distribution problem
|
||||
is reduced to a linear programming problem and solved by lp_solve. This allows for almost
|
||||
perfect (96-99% uniformity compared to Ceph's 80-90%) data distribution in most cases, ability
|
||||
to map PGs by hand without breaking rebalancing logic, reduced OSD peer-to-peer communication
|
||||
(on average, OSDs have fewer peers) and less data movement. It also probably has a drawback -
|
||||
this method may fail in very large clusters, but up to several hundreds of OSDs it's perfectly fine.
|
||||
It's also easy to add consistent hashes in the future if something proves their necessity.
|
||||
- There's no separate CRUSH layer. You select pool redundancy scheme, placement root, failure domain
|
||||
and so on directly in pool configuration.
|
||||
|
||||
## Understanding Storage Performance
|
||||
|
||||
The most important thing for fast storage is latency, not parallel iops.
|
||||
|
||||
The best possible latency is achieved with one thread and queue depth of 1 which basically means
|
||||
"client load as low as possible". In this case IOPS = 1/latency, and this number doesn't
|
||||
scale with number of servers, drives, server processes or threads and so on.
|
||||
Single-threaded IOPS and latency numbers only depend on *how fast a single daemon is*.
|
||||
|
||||
Why is it important? It's important because some of the applications *can't* use
|
||||
queue depth greater than 1 because their task isn't parallelizable. A notable example
|
||||
is any ACID DBMS because all of them write their WALs sequentially with fsync()s.
|
||||
|
||||
fsync, by the way, is another important thing often missing in benchmarks. The point is
|
||||
that drives have cache buffers and don't guarantee that your data is actually persisted
|
||||
until you call fsync() which is translated to a FLUSH CACHE command by the OS.
|
||||
|
||||
Desktop SSDs are very fast without fsync - NVMes, for example, can process ~80000 write
|
||||
operations per second with queue depth of 1 without fsync - but they're really slow with
|
||||
fsync because they have to actually write data to flash chips when you call fsync. Typical
|
||||
number is around 1000-2000 iops with fsync.
|
||||
|
||||
Server SSDs often have supercapacitors that act as a built-in UPS and allow the drive
|
||||
to flush its DRAM cache to the persistent flash storage when a power loss occurs.
|
||||
This makes them perform equally well with and without fsync. This feature is called
|
||||
"Advanced Power Loss Protection" by Intel; other vendors either call it similarly
|
||||
or directly as "Full Capacitor-Based Power Loss Protection".
|
||||
|
||||
All software-defined storages that I currently know are slow in terms of latency.
|
||||
Notable examples are Ceph and internal SDSes used by cloud providers like Amazon, Google,
|
||||
Yandex and so on. They're all slow and can only reach ~0.3ms read and ~0.6ms 4 KB write latency
|
||||
with best-in-slot hardware.
|
||||
|
||||
And that's in the SSD era when you can buy an SSD that has ~0.04ms latency for 100 $.
|
||||
|
||||
I use the following 6 commands with small variations to benchmark any storage:
|
||||
|
||||
- Linear write:
|
||||
`fio -ioengine=libaio -direct=1 -invalidate=1 -name=test -bs=4M -iodepth=32 -rw=write -runtime=60 -filename=/dev/sdX`
|
||||
- Linear read:
|
||||
`fio -ioengine=libaio -direct=1 -invalidate=1 -name=test -bs=4M -iodepth=32 -rw=read -runtime=60 -filename=/dev/sdX`
|
||||
- Random write latency (T1Q1, this hurts storages the most):
|
||||
`fio -ioengine=libaio -direct=1 -invalidate=1 -name=test -bs=4k -iodepth=1 -fsync=1 -rw=randwrite -runtime=60 -filename=/dev/sdX`
|
||||
- Random read latency (T1Q1):
|
||||
`fio -ioengine=libaio -direct=1 -invalidate=1 -name=test -bs=4k -iodepth=1 -rw=randread -runtime=60 -filename=/dev/sdX`
|
||||
- Parallel write iops (use numjobs if a single CPU core is insufficient to saturate the load):
|
||||
`fio -ioengine=libaio -direct=1 -invalidate=1 -name=test -bs=4k -iodepth=128 [-numjobs=4 -group_reporting] -rw=randwrite -runtime=60 -filename=/dev/sdX`
|
||||
- Parallel read iops (use numjobs if a single CPU core is insufficient to saturate the load):
|
||||
`fio -ioengine=libaio -direct=1 -invalidate=1 -name=test -bs=4k -iodepth=128 [-numjobs=4 -group_reporting] -rw=randread -runtime=60 -filename=/dev/sdX`
|
||||
|
||||
## Vitastor's Theoretical Maximum Random Access Performance
|
||||
|
||||
Replicated setups:
|
||||
- Single-threaded (T1Q1) read latency: 1 network roundtrip + 1 disk read.
|
||||
- Single-threaded write+fsync latency:
|
||||
- With immediate commit: 2 network roundtrips + 1 disk write.
|
||||
- With lazy commit: 4 network roundtrips + 1 disk write + 1 disk flush.
|
||||
- Saturated parallel read iops: min(network bandwidth, sum(disk read iops)).
|
||||
- Saturated parallel write iops: min(network bandwidth, sum(disk write iops / number of replicas / write amplification)).
|
||||
|
||||
EC/XOR setups:
|
||||
- Single-threaded (T1Q1) read latency: 1.5 network roundtrips + 1 disk read.
|
||||
- Single-threaded write+fsync latency:
|
||||
- With immediate commit: 3.5 network roundtrips + 1 disk read + 2 disk writes.
|
||||
- With lazy commit: 5.5 network roundtrips + 1 disk read + 2 disk writes + 2 disk fsyncs.
|
||||
- 0.5 in actually (k-1)/k which means that an additional roundtrip doesn't happen when
|
||||
the read sub-operation can be served locally.
|
||||
- Saturated parallel read iops: min(network bandwidth, sum(disk read iops)).
|
||||
- Saturated parallel write iops: min(network bandwidth, sum(disk write iops * number of data drives / (number of data + parity drives) / write amplification)).
|
||||
In fact, you should put disk write iops under the condition of ~10% reads / ~90% writes in this formula.
|
||||
|
||||
Write amplification for 4 KB blocks is usually 3-5 in Vitastor:
|
||||
1. Journal block write
|
||||
2. Journal data write
|
||||
3. Metadata block write
|
||||
4. Another journal block write for EC/XOR setups
|
||||
5. Data block write
|
||||
|
||||
If you manage to get an SSD which handles 512 byte blocks well (Optane?) you may
|
||||
lower 1, 3 and 4 to 512 bytes (1/8 of data size) and get WA as low as 2.375.
|
||||
|
||||
Lazy fsync also reduces WA for parallel workloads because journal blocks are only
|
||||
written when they fill up or fsync is requested.
|
||||
|
||||
## Example Comparison with Ceph
|
||||
|
||||
Hardware configuration: 4 nodes, each with:
|
||||
- 6x SATA SSD Intel D3-4510 3.84 TB
|
||||
- 2x Xeon Gold 6242 (16 cores @ 2.8 GHz)
|
||||
- 384 GB RAM
|
||||
- 1x 25 GbE network interface (Mellanox ConnectX-4 LX), connected to a Juniper QFX5200 switch
|
||||
|
||||
CPU powersaving was disabled. Both Vitastor and Ceph were configured with 2 OSDs per 1 SSD.
|
||||
|
||||
All of the results below apply to 4 KB blocks and random access (unless indicated otherwise).
|
||||
|
||||
Raw drive performance:
|
||||
- T1Q1 write ~27000 iops (~0.037ms latency)
|
||||
- T1Q1 read ~9800 iops (~0.101ms latency)
|
||||
- T1Q32 write ~60000 iops
|
||||
- T1Q32 read ~81700 iops
|
||||
|
||||
Ceph 15.2.4 (Bluestore):
|
||||
- T1Q1 write ~1000 iops (~1ms latency)
|
||||
- T1Q1 read ~1750 iops (~0.57ms latency)
|
||||
- T8Q64 write ~100000 iops, total CPU usage by OSDs about 40 virtual cores on each node
|
||||
- T8Q64 read ~480000 iops, total CPU usage by OSDs about 40 virtual cores on each node
|
||||
|
||||
T8Q64 tests were conducted over 8 400GB RBD images from all hosts (every host was running 2 instances of fio).
|
||||
This is because Ceph has performance penalties related to running multiple clients over a single RBD image.
|
||||
|
||||
cephx_sign_messages was set to false during tests, RocksDB and Bluestore settings were left at defaults.
|
||||
|
||||
In fact, not that bad for Ceph. These servers are an example of well-balanced Ceph nodes.
|
||||
However, CPU usage and I/O latency were through the roof, as usual.
|
||||
|
||||
Vitastor:
|
||||
- T1Q1 write: 7087 iops (0.14ms latency)
|
||||
- T1Q1 read: 6838 iops (0.145ms latency)
|
||||
- T2Q64 write: 162000 iops, total CPU usage by OSDs about 3 virtual cores on each node
|
||||
- T8Q64 read: 895000 iops, total CPU usage by OSDs about 4 virtual cores on each node
|
||||
- Linear write (4M T1Q32): 2800 MB/s
|
||||
- Linear read (4M T1Q32): 1500 MB/s
|
||||
|
||||
T8Q64 read test was conducted over 1 larger inode (3.2T) from all hosts (every host was running 2 instances of fio).
|
||||
Vitastor has no performance penalties related to running multiple clients over a single inode.
|
||||
If conducted from one node with all primary OSDs moved to other nodes the result was slightly lower (689000 iops),
|
||||
this is because all operations resulted in network roundtrips between the client and the primary OSD.
|
||||
When fio was colocated with OSDs (like in Ceph benchmarks above), 1/4 of the read workload actually
|
||||
used the loopback network.
|
||||
|
||||
Vitastor was configured with: `--disable_data_fsync true --immediate_commit all --flusher_count 8
|
||||
--disk_alignment 4096 --journal_block_size 4096 --meta_block_size 4096
|
||||
--journal_no_same_sector_overwrites true --journal_sector_buffer_count 1024
|
||||
--journal_size 16777216`.
|
||||
|
||||
### EC/XOR 2+1
|
||||
|
||||
Vitastor:
|
||||
- T1Q1 write: 2808 iops (~0.355ms latency)
|
||||
- T1Q1 read: 6190 iops (~0.16ms latency)
|
||||
- T2Q64 write: 85500 iops, total CPU usage by OSDs about 3.4 virtual cores on each node
|
||||
- T8Q64 read: 812000 iops, total CPU usage by OSDs about 4.7 virtual cores on each node
|
||||
- Linear write (4M T1Q32): 3200 MB/s
|
||||
- Linear read (4M T1Q32): 1800 MB/s
|
||||
|
||||
Ceph:
|
||||
- T1Q1 write: 730 iops (~1.37ms latency)
|
||||
- T1Q1 read: 1500 iops with cold cache (~0.66ms latency), 2300 iops after 2 minute metadata cache warmup (~0.435ms latency)
|
||||
- T4Q128 write (4 RBD images): 45300 iops, total CPU usage by OSDs about 30 virtual cores on each node
|
||||
- T8Q64 read (4 RBD images): 278600 iops, total CPU usage by OSDs about 40 virtual cores on each node
|
||||
- Linear write (4M T1Q32): 1950 MB/s before preallocation, 2500 MB/s after preallocation
|
||||
- Linear read (4M T1Q32): 2400 MB/s
|
||||
|
||||
### NBD
|
||||
|
||||
NBD is currently required to mount Vitastor via kernel, but it imposes additional overhead
|
||||
due to additional copying between the kernel and userspace. This mostly hurts linear
|
||||
bandwidth, not iops.
|
||||
|
||||
Vitastor with single-thread NBD on the same hardware:
|
||||
- T1Q1 write: 6000 iops (0.166ms latency)
|
||||
- T1Q1 read: 5518 iops (0.18ms latency)
|
||||
- T1Q128 write: 94400 iops
|
||||
- T1Q128 read: 103000 iops
|
||||
- Linear write (4M T1Q128): 1266 MB/s (compared to 2800 MB/s via fio)
|
||||
- Linear read (4M T1Q128): 975 MB/s (compared to 1500 MB/s via fio)
|
||||
|
||||

### Building from Source
|
||||
|
||||
- Install Linux kernel 5.4 or newer, for io_uring support. 5.8 or later is highly recommended because
|
||||
there is at least one known io_uring hang with 5.4 and an HP SmartArray controller.
|
||||
- Install liburing 0.4 or newer and its headers.
|
||||
- Install lp_solve.
|
||||
- Install etcd, at least version 3.4.15. Earlier versions won't work because of various bugs,
|
||||
for example [#12402](https://github.com/etcd-io/etcd/pull/12402). You can also take 3.4.13
|
||||
with this specific fix from here: https://github.com/vitalif/etcd/, branch release-3.4.
|
||||
- Install node.js 10 or newer.
|
||||
- Install gcc and g++ 8.x or newer.
|
||||
- Clone https://yourcmc.ru/git/vitalif/vitastor/ with submodules.
|
||||
- Install QEMU 3.0+, get its source, begin to build it, stop the build and copy headers:
|
||||
- `<qemu>/include` → `<vitastor>/qemu/include`
|
||||
- Debian:
|
||||
* Use qemu packages from the main repository
|
||||
* `<qemu>/b/qemu/config-host.h` → `<vitastor>/qemu/b/qemu/config-host.h`
|
||||
* `<qemu>/b/qemu/qapi` → `<vitastor>/qemu/b/qemu/qapi`
|
||||
- CentOS 8:
|
||||
* Use qemu packages from the Advanced-Virtualization repository. To enable it, run
|
||||
`yum install centos-release-advanced-virtualization.noarch` and then `yum install qemu`
|
||||
* `<qemu>/config-host.h` → `<vitastor>/qemu/b/qemu/config-host.h`
|
||||
* For QEMU 3.0+: `<qemu>/qapi` → `<vitastor>/qemu/b/qemu/qapi`
|
||||
* For QEMU 2.0+: `<qemu>/qapi-types.h` → `<vitastor>/qemu/b/qemu/qapi-types.h`
|
||||
- `config-host.h` and `qapi` are required because they contain generated headers
|
||||
- You can also rebuild QEMU with a patch that makes LD_PRELOAD unnecessary to load vitastor driver.
|
||||
See `patches/qemu-*.*-vitastor.patch`.
|
||||
- Install fio 3.7 or later, get its source and symlink it into `<vitastor>/fio`.
|
||||
- Build & install Vitastor with `mkdir build && cd build && cmake .. && make -j8 && make install`.
|
||||
Pay attention to the `QEMU_PLUGINDIR` cmake option - it must be set to `qemu-kvm` on RHEL.
|
||||
|
||||
## Running
|
||||
|
||||
Please note that startup procedure isn't currently simple - you specify configuration
|
||||
and calculate disk offsets almost by hand. This will be fixed in near future.
|
||||
|
||||
- Get some SATA or NVMe SSDs with capacitors (server-grade drives). You can use desktop SSDs
|
||||
with lazy fsync, but prepare for inferior single-thread latency.
|
||||
- Get a fast network (at least 10 Gbit/s).
|
||||
- Disable CPU powersaving: `cpupower idle-set -D 0 && cpupower frequency-set -g performance`.
|
||||
- On the monitor hosts:
|
||||
- Edit variables at the top of `/usr/lib/vitastor/mon/make-units.sh` to desired values.
|
||||
- Create systemd units for the monitor and etcd: `/usr/lib/vitastor/mon/make-units.sh`
|
||||
- Put etcd_address and osd_network into `/etc/vitastor/vitastor.conf`. Example:
|
||||
```
|
||||
{
|
||||
"etcd_address": ["10.200.1.10:2379","10.200.1.11:2379","10.200.1.12:2379"],
|
||||
"osd_network": "10.200.1.0/24"
|
||||
}
|
||||
```
|
||||
- Create systemd units for your OSDs: `/usr/lib/vitastor/mon/make-osd.sh /dev/disk/by-partuuid/XXX [/dev/disk/by-partuuid/YYY ...]`
|
||||
- You can change OSD configuration in units or in `vitastor.conf`. Notable configuration variables:
|
||||
- `disable_data_fsync 1` - only safe with server-grade drives with capacitors.
|
||||
- `immediate_commit all` - use this if all your drives are server-grade.
|
||||
If all OSDs have it set to all then you should also put the same value in etcd into /vitastor/config/global
|
||||
- `disable_device_lock 1` - only required if you run multiple OSDs on one block device.
|
||||
- `flusher_count 256` - flusher is a micro-thread that removes old data from the journal.
|
||||
You don't have to worry about this parameter anymore, 256 is enough.
|
||||
- `disk_alignment`, `journal_block_size`, `meta_block_size` should be set to the internal
|
||||
block size of your SSDs which is 4096 on most drives.
|
||||
- `journal_no_same_sector_overwrites true` prevents multiple overwrites of the same journal sector.
|
||||
Most (99%) SSDs don't need this option. But Intel D3-4510 does because it doesn't like when you
|
||||
overwrite the same sector twice in a short period of time. The setting forces Vitastor to never
|
||||
overwrite the same journal sector twice in a row which makes D3-4510 almost happy. Not totally
|
||||
happy, because overwrites of the same block can still happen in the metadata area... When this
|
||||
setting is set, it is also required to raise `journal_sector_buffer_count` setting, which is the
|
||||
number of dirty journal sectors that may be written to at the same time.
|
||||
- `systemctl start vitastor.target` everywhere.
|
||||
- Create global configuration in etcd: `etcdctl --endpoints=... put /vitastor/config/global '{"immediate_commit":"all"}'`
|
||||
(if all your drives have capacitors).
|
||||
- Create pool configuration in etcd: `etcdctl --endpoints=... put /vitastor/config/pools '{"1":{"name":"testpool","scheme":"replicated","pg_size":2,"pg_minsize":1,"pg_count":256,"failure_domain":"host"}}'`.
|
||||
For jerasure pools the configuration should look like the following: `2:{"name":"ecpool","scheme":"jerasure","pg_size":4,"parity_chunks":2,"pg_minsize":2,"pg_count":256,"failure_domain":"host"}`.
|
||||
- At this point, one of the monitors will configure PGs and OSDs will start them.
|
||||
- You can check PG states with `etcdctl --endpoints=... get --prefix /vitastor/pg/state`. All PGs should become 'active'.
|
||||
|
||||
### Name an image
|
||||
|
||||
```
|
||||
etcdctl --endpoints=<etcd> put /vitastor/config/inode/<pool>/<inode> '{"name":"<name>","size":<size>[,"parent_id":<parent_inode_number>][,"readonly":true]}'
|
||||
```
|
||||
|
||||
For example:
|
||||
|
||||
```
|
||||
etcdctl --endpoints=http://10.115.0.10:2379/v3 put /vitastor/config/inode/1/1 '{"name":"testimg","size":2147483648}'
|
||||
```
|
||||
|
||||
If you specify parent_id the image becomes a CoW clone. I.e. all writes go to the new inode and reads first check it
|
||||
and then upper layers. You can then make parent readonly by updating its entry with `"readonly":true` for safety and
|
||||
basically treat it as a snapshot.
|
||||
|
||||
So to create a snapshot you basically rename the previous upper layer (for example from testimg to testimg@0), make it readonly
|
||||
and create a new top layer with the original name (testimg) and the previous one as a parent.
|
||||
|
||||
### Run fio benchmarks
|
||||
|
||||
fio command example:
|
||||
|
||||
```
|
||||
fio -thread -ioengine=libfio_vitastor.so -name=test -bs=4M -direct=1 -iodepth=16 -rw=write -etcd=10.115.0.10:2379/v3 -image=testimg
|
||||
```
|
||||
|
||||
If you don't want to access your image by name, you can specify pool number, inode number and size
|
||||
(`-pool=1 -inode=1 -size=400G`) instead of the image name (`-image=testimg`).
|
||||
|
||||
### Upload VM image
|
||||
|
||||
Use qemu-img and `vitastor:etcd_host=<HOST>:image=<IMAGE>` disk filename. For example:
|
||||
|
||||
```
|
||||
qemu-img convert -f qcow2 debian10.qcow2 -p -O raw 'vitastor:etcd_host=10.115.0.10\:2379/v3:image=testimg'
|
||||
```
|
||||
|
||||
Note that the command requires to be run with `LD_PRELOAD=/usr/lib/x86_64-linux-gnu/qemu/block-vitastor.so qemu-img ...`
|
||||
if you use unmodified QEMU.
|
||||
|
||||
You can also specify `:pool=<POOL>:inode=<INODE>:size=<SIZE>` instead of `:image=<IMAGE>`
|
||||
if you don't want to use inode metadata.
|
||||
|
||||
### Start a VM
|
||||
|
||||
Run QEMU with `-drive file=vitastor:etcd_host=<HOST>:image=<IMAGE>` and use 4 KB physical block size.
|
||||
|
||||
For example:
|
||||
|
||||
```
|
||||
qemu-system-x86_64 -enable-kvm -m 1024
|
||||
-drive 'file=vitastor:etcd_host=10.115.0.10\:2379/v3:image=testimg',format=raw,if=none,id=drive-virtio-disk0,cache=none
|
||||
-device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x5,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1,write-cache=off,physical_block_size=4096,logical_block_size=512
|
||||
-vnc 0.0.0.0:0
|
||||
```
|
||||
|
||||
You can also specify `:pool=<POOL>:inode=<INODE>:size=<SIZE>` instead of `:image=<IMAGE>`,
|
||||
just like in qemu-img.
|
||||
|
||||
### Remove inode
|
||||
|
||||
Use vitastor-rm / vitastor-cli rm-data. For example:
|
||||
|
||||
```
|
||||
vitastor-cli rm-data --etcd_address 10.115.0.10:2379/v3 --pool 1 --inode 1 --parallel_osds 16 --iodepth 32
|
||||
```
|
||||
|
||||
### NBD
|
||||
|
||||
To create a local block device for a Vitastor image, use NBD. For example:
|
||||
|
||||
```
|
||||
vitastor-nbd map --etcd_address 10.115.0.10:2379/v3 --image testimg
|
||||
```
|
||||
|
||||
It will output the device name, like /dev/nbd0 which you can then format and mount as a normal block device.
|
||||
|
||||
Again, you can use `--pool <POOL> --inode <INODE> --size <SIZE>` insteaf of `--image <IMAGE>` if you want.
|
||||
|
||||
### Kubernetes
|
||||
|
||||
Vitastor has a CSI plugin for Kubernetes which supports RWO volumes.
|
||||
|
||||
To deploy it, take manifests from [csi/deploy/](csi/deploy/) directory, put your
|
||||
Vitastor configuration in [csi/deploy/001-csi-config-map.yaml](001-csi-config-map.yaml),
|
||||
configure storage class in [csi/deploy/009-storage-class.yaml](009-storage-class.yaml)
|
||||
and apply all `NNN-*.yaml` manifests to your Kubernetes installation:
|
||||
|
||||
```
|
||||
for i in ./???-*.yaml; do kubectl apply -f $i; done
|
||||
```
|
||||
|
||||
After that you'll be able to create PersistentVolumes. See example in [csi/deploy/example-pvc.yaml](csi/deploy/example-pvc.yaml).
|
||||
|
||||
### OpenStack
|
||||
|
||||
To enable Vitastor support in an OpenStack installation:
|
||||
|
||||
- Install vitastor-client, patched QEMU and libvirt packages from Vitastor DEB or RPM repository
|
||||
- Use `patches/nova-21.diff` or `patches/nova-23.diff` to patch your Nova installation.
|
||||
Patch 21 fits Nova 21-22, patch 23 fits Nova 23-24.
|
||||
- Install `patches/cinder-vitastor.py` as `..../cinder/volume/drivers/vitastor.py`
|
||||
- Define a volume type in cinder.conf (see below)
|
||||
- Block network access from VMs to Vitastor network (to OSDs and etcd), because Vitastor doesn't support authentication (yet)
|
||||
- Restart Cinder and Nova
|
||||
|
||||
Cinder volume type configuration example:
|
||||
|
||||
```
|
||||
[DEFAULT]
|
||||
enabled_backends = lvmdriver-1, vitastor-testcluster
|
||||
# ...
|
||||
|
||||
[vitastor-testcluster]
|
||||
volume_driver = cinder.volume.drivers.vitastor.VitastorDriver
|
||||
volume_backend_name = vitastor-testcluster
|
||||
image_volume_cache_enabled = True
|
||||
volume_clear = none
|
||||
vitastor_etcd_address = 192.168.7.2:2379
|
||||
vitastor_etcd_prefix =
|
||||
vitastor_config_path = /etc/vitastor/vitastor.conf
|
||||
vitastor_pool_id = 1
|
||||
image_upload_use_cinder_backend = True
|
||||
```
|
||||
|
||||
To put Glance images in Vitastor, use [https://docs.openstack.org/cinder/pike/admin/blockstorage-volume-backed-image.html](volume-backed images),
|
||||
although the support has not been verified yet.
|
||||
|
||||
### Proxmox
|
||||
|
||||
To enable Vitastor support in Proxmox Virtual Environment (6.4 and 7.1 are supported):
|
||||
|
||||
- Add the corresponding Vitastor Debian repository into sources.list on Proxmox hosts
|
||||
(buster for 6.4, bullseye for 7.1)
|
||||
- Install vitastor-client, pve-qemu-kvm, pve-storage-vitastor (* or see note) packages from Vitastor repository
|
||||
- Define storage in `/etc/pve/storage.cfg` (see below)
|
||||
- Block network access from VMs to Vitastor network (to OSDs and etcd), because Vitastor doesn't support authentication (yet)
|
||||
- Restart pvedaemon: `systemctl restart pvedaemon`
|
||||
|
||||
`/etc/pve/storage.cfg` example (the only required option is vitastor_pool, all others
|
||||
are listed below with their default values):
|
||||
|
||||
```
|
||||
vitastor: vitastor
|
||||
# pool to put new images into
|
||||
vitastor_pool testpool
|
||||
# path to the configuration file
|
||||
vitastor_config_path /etc/vitastor/vitastor.conf
|
||||
# etcd address(es), required only if missing in the configuration file
|
||||
vitastor_etcd_address 192.168.7.2:2379/v3
|
||||
# prefix for keys in etcd
|
||||
vitastor_etcd_prefix /vitastor
|
||||
# prefix for images
|
||||
vitastor_prefix pve/
|
||||
# use NBD mounter (only required for containers)
|
||||
vitastor_nbd 0
|
||||
```
|
||||
|
||||
\* Note: you can also manually copy [patches/PVE_VitastorPlugin.pm](patches/PVE_VitastorPlugin.pm) to Proxmox hosts
|
||||
as `/usr/share/perl5/PVE/Storage/Custom/VitastorPlugin.pm` instead of installing pve-storage-vitastor.
|
||||
|
||||
## Known Problems
|
||||
|
||||
- Object deletion requests may currently lead to 'incomplete' objects in EC pools
|
||||
if your OSDs crash during deletion because proper handling of object cleanup
|
||||
in a cluster should be "three-phase" and it's currently not implemented.
|
||||
Just repeat the removal request again in this case.
|
||||
|
||||
## Implementation Principles
|
||||
|
||||
- I like architecturally simple solutions. Vitastor is and will always be designed
|
||||
exactly like that.
|
||||
- I also like reinventing the wheel to some extent, like writing my own HTTP client
|
||||
for etcd interaction instead of using prebuilt libraries, because in this case
|
||||
I'm confident about what my code does and what it doesn't do.
|
||||
- I don't care about C++ "best practices" like RAII or proper inheritance or usage of
|
||||
smart pointers or whatever and I don't intend to change my mind, so if you're here
|
||||
looking for ideal reference C++ code, this probably isn't the right place.
|
||||
- I like node.js better than any other dynamically-typed language interpreter
|
||||
because it's faster than any other interpreter in the world, has neutral C-like
|
||||
syntax and built-in event loop. That's why Monitor is implemented in node.js.

VITASTOR NETWORK PUBLIC LICENSE
|
||||
Version 1.1, 6 February 2021
|
||||
|
||||
Copyright (C) 2021 Vitaliy Filippov <vitalif@yourcmc.ru>
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The Vitastor Network Public License is a free, copyleft license for
|
||||
software and other kinds of works, specifically designed to ensure
|
||||
cooperation with the community in the case of network server software.
|
||||
|
||||
The licenses for most software and other practical works are designed
|
||||
to take away your freedom to share and change the works. By contrast,
|
||||
GNU General Public Licenses and Vitastor Network Public License are
|
||||
intended to guarantee your freedom to share and change all versions
|
||||
of a program--to make sure it remains free software for all its users.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. GNU General Public Licenses and Vitastor Network Public License
|
||||
are designed to make sure that you have the freedom to distribute copies
|
||||
of free software (and charge for them if you wish), that you receive
|
||||
source code or can get it if you want it, that you can change the software
|
||||
or use pieces of it in new free programs, and that you know you can do these
|
||||
things.
|
||||
|
||||
Developers that use GNU General Public Licenses and Vitastor
|
||||
Network Public License protect your rights with two steps:
|
||||
(1) assert copyright on the software, and (2) offer
|
||||
you this License which gives you legal permission to copy, distribute
|
||||
and/or modify the software.
|
||||
|
||||
A secondary benefit of defending all users' freedom is that
|
||||
improvements made in alternate versions of the program, if they
|
||||
receive widespread use, become available for other developers to
|
||||
incorporate. Many developers of free software are heartened and
|
||||
encouraged by the resulting cooperation. However, in the case of
|
||||
software used on network servers, this result may fail to come about.
|
||||
The GNU General Public License permits making a modified version and
|
||||
letting the public access it on a server without ever releasing its
|
||||
source code to the public. Even the GNU Affero General Public License
|
||||
permits running a modified version in a closed environment where
|
||||
public users only interact with it through a closed-source proxy, again,
|
||||
without making the program and the proxy available to the public
|
||||
for free.
|
||||
|
||||
The Vitastor Network Public License is designed specifically to
|
||||
ensure that, in such cases, the modified program and the proxy stays
|
||||
available to the community. It requires the operator of a network server to
|
||||
provide the source code of the original program and all other programs
|
||||
communicating with it running there to the users of that server.
|
||||
Therefore, public use of a modified version, on a server accessible
|
||||
directly or indirectly to the public, gives the public access to the source
|
||||
code of the modified version.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
TERMS AND CONDITIONS
|
||||
|
||||
0. Definitions.
|
||||
|
||||
"This License" refers to version 1 of the Vitastor Network Public License.
|
||||
|
||||
"Copyright" also means copyright-like laws that apply to other kinds of
|
||||
works, such as semiconductor masks.
|
||||
|
||||
"The Program" refers to any copyrightable work licensed under this
|
||||
License. Each licensee is addressed as "you". "Licensees" and
|
||||
"recipients" may be individuals or organizations.
|
||||
|
||||
To "modify" a work means to copy from or adapt all or part of the work
|
||||
in a fashion requiring copyright permission, other than the making of an
|
||||
exact copy. The resulting work is called a "modified version" of the
|
||||
earlier work or a work "based on" the earlier work.
|
||||
|
||||
A "covered work" means either the unmodified Program or a work based
|
||||
on the Program.
|
||||
|
||||
To "propagate" a work means to do anything with it that, without
|
||||
permission, would make you directly or secondarily liable for
|
||||
infringement under applicable copyright law, except executing it on a
|
||||
computer or modifying a private copy. Propagation includes copying,
|
||||
distribution (with or without modification), making available to the
|
||||
public, and in some countries other activities as well.
|
||||
|
||||
To "convey" a work means any kind of propagation that enables other
|
||||
parties to make or receive copies. Mere interaction with a user through
|
||||
a computer network, with no transfer of a copy, is not conveying.
|
||||
|
||||
An interactive user interface displays "Appropriate Legal Notices"
|
||||
to the extent that it includes a convenient and prominently visible
|
||||
feature that (1) displays an appropriate copyright notice, and (2)
|
||||
tells the user that there is no warranty for the work (except to the
|
||||
extent that warranties are provided), that licensees may convey the
|
||||
work under this License, and how to view a copy of this License. If
|
||||
the interface presents a list of user commands or options, such as a
|
||||
menu, a prominent item in the list meets this criterion.
|
||||
|
||||
1. Source Code.
|
||||
|
||||
The "source code" for a work means the preferred form of the work
|
||||
for making modifications to it. "Object code" means any non-source
|
||||
form of a work.
|
||||
|
||||
A "Standard Interface" means an interface that either is an official
|
||||
standard defined by a recognized standards body, or, in the case of
|
||||
interfaces specified for a particular programming language, one that
|
||||
is widely used among developers working in that language.
|
||||
|
||||
The "System Libraries" of an executable work include anything, other
|
||||
than the work as a whole, that (a) is included in the normal form of
|
||||
packaging a Major Component, but which is not part of that Major
|
||||
Component, and (b) serves only to enable use of the work with that
|
||||
Major Component, or to implement a Standard Interface for which an
|
||||
implementation is available to the public in source code form. A
|
||||
"Major Component", in this context, means a major essential component
|
||||
(kernel, window system, and so on) of the specific operating system
|
||||
(if any) on which the executable work runs, or a compiler used to
|
||||
produce the work, or an object code interpreter used to run it.
|
||||
|
||||
The "Corresponding Source" for a work in object code form means all
|
||||
the source code needed to generate, install, and (for an executable
|
||||
work) run the object code and to modify the work, including scripts to
|
||||
control those activities. However, it does not include the work's
|
||||
System Libraries, or general-purpose tools or generally available free
|
||||
programs which are used unmodified in performing those activities but
|
||||
which are not part of the work. For example, Corresponding Source
|
||||
includes interface definition files associated with source files for
|
||||
the work, and the source code for shared libraries and dynamically
|
||||
linked subprograms that the work is specifically designed to require,
|
||||
such as by intimate data communication or control flow between those
|
||||
subprograms and other parts of the work.
|
||||
|
||||
The Corresponding Source need not include anything that users
|
||||
can regenerate automatically from other parts of the Corresponding
|
||||
Source.
|
||||
|
||||
The Corresponding Source for a work in source code form is that
|
||||
same work.
|
||||
|
||||
2. Basic Permissions.
|
||||
|
||||
All rights granted under this License are granted for the term of
|
||||
copyright on the Program, and are irrevocable provided the stated
|
||||
conditions are met. This License explicitly affirms your unlimited
|
||||
permission to run the unmodified Program. The output from running a
|
||||
covered work is covered by this License only if the output, given its
|
||||
content, constitutes a covered work. This License acknowledges your
|
||||
rights of fair use or other equivalent, as provided by copyright law.
|
||||
|
||||
You may make, run and propagate covered works that you do not
|
||||
convey, without conditions so long as your license otherwise remains
|
||||
in force. You may convey covered works to others for the sole purpose
|
||||
of having them make modifications exclusively for you, or provide you
|
||||
with facilities for running those works, provided that you comply with
|
||||
the terms of this License in conveying all material for which you do
|
||||
not control copyright. Those thus making or running the covered works
|
||||
for you must do so exclusively on your behalf, under your direction
|
||||
and control, on terms that prohibit them from making any copies of
|
||||
your copyrighted material outside their relationship with you.
|
||||
|
||||
Conveying under any other circumstances is permitted solely under
|
||||
the conditions stated below. Sublicensing is not allowed; section 10
|
||||
makes it unnecessary.
|
||||
|
||||
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
||||
|
||||
No covered work shall be deemed part of an effective technological
|
||||
measure under any applicable law fulfilling obligations under article
|
||||
11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
||||
similar laws prohibiting or restricting circumvention of such
|
||||
measures.
|
||||
|
||||
When you convey a covered work, you waive any legal power to forbid
|
||||
circumvention of technological measures to the extent such circumvention
|
||||
is effected by exercising rights under this License with respect to
|
||||
the covered work, and you disclaim any intention to limit operation or
|
||||
modification of the work as a means of enforcing, against the work's
|
||||
users, your or third parties' legal rights to forbid circumvention of
|
||||
technological measures.
|
||||
|
||||
4. Conveying Verbatim Copies.
|
||||
|
||||
You may convey verbatim copies of the Program's source code as you
|
||||
receive it, in any medium, provided that you conspicuously and
|
||||
appropriately publish on each copy an appropriate copyright notice;
|
||||
keep intact all notices stating that this License and any
|
||||
non-permissive terms added in accord with section 7 apply to the code;
|
||||
keep intact all notices of the absence of any warranty; and give all
|
||||
recipients a copy of this License along with the Program.
|
||||
|
||||
You may charge any price or no price for each copy that you convey,
|
||||
and you may offer support or warranty protection for a fee.
|
||||
|
||||
5. Conveying Modified Source Versions.
|
||||
|
||||
You may convey a work based on the Program, or the modifications to
|
||||
produce it from the Program, in the form of source code under the
|
||||
terms of section 4, provided that you also meet all of these conditions:
|
||||
|
||||
a) The work must carry prominent notices stating that you modified
|
||||
it, and giving a relevant date.
|
||||
|
||||
b) The work must carry prominent notices stating that it is
|
||||
released under this License and any conditions added under section
|
||||
7. This requirement modifies the requirement in section 4 to
|
||||
"keep intact all notices".
|
||||
|
||||
c) You must license the entire work, as a whole, under this
|
||||
License to anyone who comes into possession of a copy. This
|
||||
License will therefore apply, along with any applicable section 7
|
||||
additional terms, to the whole of the work, and all its parts,
|
||||
regardless of how they are packaged. This License gives no
|
||||
permission to license the work in any other way, but it does not
|
||||
invalidate such permission if you have separately received it.
|
||||
|
||||
d) If the work has interactive user interfaces, each must display
|
||||
Appropriate Legal Notices; however, if the Program has interactive
|
||||
interfaces that do not display Appropriate Legal Notices, your
|
||||
work need not make them do so.
|
||||
|
||||
A compilation of a covered work with other separate and independent
|
||||
works, which are not by their nature extensions of the covered work,
|
||||
and which are not combined with it such as to form a larger program,
|
||||
in or on a volume of a storage or distribution medium, is called an
|
||||
"aggregate" if the compilation and its resulting copyright are not
|
||||
used to limit the access or legal rights of the compilation's users
|
||||
beyond what the individual works permit. Inclusion of a covered work
|
||||
in an aggregate does not cause this License to apply to the other
|
||||
parts of the aggregate.
|
||||
|
||||
6. Conveying Non-Source Forms.
|
||||
|
||||
You may convey a covered work in object code form under the terms
|
||||
of sections 4 and 5, provided that you also convey the
|
||||
machine-readable Corresponding Source under the terms of this License,
|
||||
in one of these ways:
|
||||
|
||||
a) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by the
|
||||
Corresponding Source fixed on a durable physical medium
|
||||
customarily used for software interchange.
|
||||
|
||||
b) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by a
|
||||
written offer, valid for at least three years and valid for as
|
||||
long as you offer spare parts or customer support for that product
|
||||
model, to give anyone who possesses the object code either (1) a
|
||||
copy of the Corresponding Source for all the software in the
|
||||
product that is covered by this License, on a durable physical
|
||||
medium customarily used for software interchange, for a price no
|
||||
more than your reasonable cost of physically performing this
|
||||
conveying of source, or (2) access to copy the
|
||||
Corresponding Source from a network server at no charge.
|
||||
|
||||
c) Convey individual copies of the object code with a copy of the
|
||||
written offer to provide the Corresponding Source. This
|
||||
alternative is allowed only occasionally and noncommercially, and
|
||||
only if you received the object code with such an offer, in accord
|
||||
with subsection 6b.
|
||||
|
||||
d) Convey the object code by offering access from a designated
|
||||
place (gratis or for a charge), and offer equivalent access to the
|
||||
Corresponding Source in the same way through the same place at no
|
||||
further charge. You need not require recipients to copy the
|
||||
Corresponding Source along with the object code. If the place to
|
||||
copy the object code is a network server, the Corresponding Source
|
||||
may be on a different server (operated by you or a third party)
|
||||
that supports equivalent copying facilities, provided you maintain
|
||||
clear directions next to the object code saying where to find the
|
||||
Corresponding Source. Regardless of what server hosts the
|
||||
Corresponding Source, you remain obligated to ensure that it is
|
||||
available for as long as needed to satisfy these requirements.
|
||||
|
||||
e) Convey the object code using peer-to-peer transmission, provided
|
||||
you inform other peers where the object code and Corresponding
|
||||
Source of the work are being offered to the general public at no
|
||||
charge under subsection 6d.
|
||||
|
||||
A separable portion of the object code, whose source code is excluded
|
||||
from the Corresponding Source as a System Library, need not be
|
||||
included in conveying the object code work.
|
||||
|
||||
A "User Product" is either (1) a "consumer product", which means any
|
||||
tangible personal property which is normally used for personal, family,
|
||||
or household purposes, or (2) anything designed or sold for incorporation
|
||||
into a dwelling. In determining whether a product is a consumer product,
|
||||
doubtful cases shall be resolved in favor of coverage. For a particular
|
||||
product received by a particular user, "normally used" refers to a
|
||||
typical or common use of that class of product, regardless of the status
|
||||
of the particular user or of the way in which the particular user
|
||||
actually uses, or expects or is expected to use, the product. A product
|
||||
is a consumer product regardless of whether the product has substantial
|
||||
commercial, industrial or non-consumer uses, unless such uses represent
|
||||
the only significant mode of use of the product.
|
||||
|
||||
"Installation Information" for a User Product means any methods,
|
||||
procedures, authorization keys, or other information required to install
|
||||
and execute modified versions of a covered work in that User Product from
|
||||
a modified version of its Corresponding Source. The information must
|
||||
suffice to ensure that the continued functioning of the modified object
|
||||
code is in no case prevented or interfered with solely because
|
||||
modification has been made.
|
||||
|
||||
If you convey an object code work under this section in, or with, or
|
||||
specifically for use in, a User Product, and the conveying occurs as
|
||||
part of a transaction in which the right of possession and use of the
|
||||
User Product is transferred to the recipient in perpetuity or for a
|
||||
fixed term (regardless of how the transaction is characterized), the
|
||||
Corresponding Source conveyed under this section must be accompanied
|
||||
by the Installation Information. But this requirement does not apply
|
||||
if neither you nor any third party retains the ability to install
|
||||
modified object code on the User Product (for example, the work has
|
||||
been installed in ROM).
|
||||
|
||||
The requirement to provide Installation Information does not include a
|
||||
requirement to continue to provide support service, warranty, or updates
|
||||
for a work that has been modified or installed by the recipient, or for
|
||||
the User Product in which it has been modified or installed. Access to a
|
||||
network may be denied when the modification itself materially and
|
||||
adversely affects the operation of the network or violates the rules and
|
||||
protocols for communication across the network.
|
||||
|
||||
Corresponding Source conveyed, and Installation Information provided,
|
||||
in accord with this section must be in a format that is publicly
|
||||
documented (and with an implementation available to the public in
|
||||
source code form), and must require no special password or key for
|
||||
unpacking, reading or copying.
|
||||
|
||||
7. Additional Terms.
|
||||
|
||||
"Additional permissions" are terms that supplement the terms of this
|
||||
License by making exceptions from one or more of its conditions.
|
||||
Additional permissions that are applicable to the entire Program shall
|
||||
be treated as though they were included in this License, to the extent
|
||||
that they are valid under applicable law. If additional permissions
|
||||
apply only to part of the Program, that part may be used separately
|
||||
under those permissions, but the entire Program remains governed by
|
||||
this License without regard to the additional permissions.
|
||||
|
||||
When you convey a copy of a covered work, you may at your option
|
||||
remove any additional permissions from that copy, or from any part of
|
||||
it. (Additional permissions may be written to require their own
|
||||
removal in certain cases when you modify the work.) You may place
|
||||
additional permissions on material, added by you to a covered work,
|
||||
for which you have or can give appropriate copyright permission.
|
||||
|
||||
Notwithstanding any other provision of this License, for material you
|
||||
add to a covered work, you may (if authorized by the copyright holders of
|
||||
that material) supplement the terms of this License with terms:
|
||||
|
||||
a) Disclaiming warranty or limiting liability differently from the
|
||||
terms of sections 15 and 16 of this License; or
|
||||
|
||||
b) Requiring preservation of specified reasonable legal notices or
|
||||
author attributions in that material or in the Appropriate Legal
|
||||
Notices displayed by works containing it; or
|
||||
|
||||
c) Prohibiting misrepresentation of the origin of that material, or
|
||||
requiring that modified versions of such material be marked in
|
||||
reasonable ways as different from the original version; or
|
||||
|
||||
d) Limiting the use for publicity purposes of names of licensors or
|
||||
authors of the material; or
|
||||
|
||||
e) Declining to grant rights under trademark law for use of some
|
||||
trade names, trademarks, or service marks; or
|
||||
|
||||
f) Requiring indemnification of licensors and authors of that
|
||||
material by anyone who conveys the material (or modified versions of
|
||||
it) with contractual assumptions of liability to the recipient, for
|
||||
any liability that these contractual assumptions directly impose on
|
||||
those licensors and authors.
|
||||
|
||||
All other non-permissive additional terms are considered "further
|
||||
restrictions" within the meaning of section 10. If the Program as you
|
||||
received it, or any part of it, contains a notice stating that it is
|
||||
governed by this License along with a term that is a further
|
||||
restriction, you may remove that term. If a license document contains
|
||||
a further restriction but permits relicensing or conveying under this
|
||||
License, you may add to a covered work material governed by the terms
|
||||
of that license document, provided that the further restriction does
|
||||
not survive such relicensing or conveying.
|
||||
|
||||
If you add terms to a covered work in accord with this section, you
|
||||
must place, in the relevant source files, a statement of the
|
||||
additional terms that apply to those files, or a notice indicating
|
||||
where to find the applicable terms.
|
||||
|
||||
Additional terms, permissive or non-permissive, may be stated in the
|
||||
form of a separately written license, or stated as exceptions;
|
||||
the above requirements apply either way.
|
||||
|
||||
8. Termination.
|
||||
|
||||
You may not propagate or modify a covered work except as expressly
|
||||
provided under this License. Any attempt otherwise to propagate or
|
||||
modify it is void, and will automatically terminate your rights under
|
||||
this License (including any patent licenses granted under the third
|
||||
paragraph of section 11).
|
||||
|
||||
However, if you cease all violation of this License, then your
|
||||
license from a particular copyright holder is reinstated (a)
|
||||
provisionally, unless and until the copyright holder explicitly and
|
||||
finally terminates your license, and (b) permanently, if the copyright
|
||||
holder fails to notify you of the violation by some reasonable means
|
||||
prior to 60 days after the cessation.
|
||||
|
||||
Moreover, your license from a particular copyright holder is
|
||||
reinstated permanently if the copyright holder notifies you of the
|
||||
violation by some reasonable means, this is the first time you have
|
||||
received notice of violation of this License (for any work) from that
|
||||
copyright holder, and you cure the violation prior to 30 days after
|
||||
your receipt of the notice.
|
||||
|
||||
Termination of your rights under this section does not terminate the
|
||||
licenses of parties who have received copies or rights from you under
|
||||
this License. If your rights have been terminated and not permanently
|
||||
reinstated, you do not qualify to receive new licenses for the same
|
||||
material under section 10.
|
||||
|
||||
9. Acceptance Not Required for Having Copies.
|
||||
|
||||
You are not required to accept this License in order to receive or
|
||||
run a copy of the Program. Ancillary propagation of a covered work
|
||||
occurring solely as a consequence of using peer-to-peer transmission
|
||||
to receive a copy likewise does not require acceptance. However,
|
||||
nothing other than this License grants you permission to propagate or
|
||||
modify any covered work. These actions infringe copyright if you do
|
||||
not accept this License. Therefore, by modifying or propagating a
|
||||
covered work, you indicate your acceptance of this License to do so.
|
||||
|
||||
10. Automatic Licensing of Downstream Recipients.
|
||||
|
||||
Each time you convey a covered work, the recipient automatically
|
||||
receives a license from the original licensors, to run, modify and
|
||||
propagate that work, subject to this License. You are not responsible
|
||||
for enforcing compliance by third parties with this License.
|
||||
|
||||
An "entity transaction" is a transaction transferring control of an
|
||||
organization, or substantially all assets of one, or subdividing an
|
||||
organization, or merging organizations. If propagation of a covered
|
||||
work results from an entity transaction, each party to that
|
||||
transaction who receives a copy of the work also receives whatever
|
||||
licenses to the work the party's predecessor in interest had or could
|
||||
give under the previous paragraph, plus a right to possession of the
|
||||
Corresponding Source of the work from the predecessor in interest, if
|
||||
the predecessor has it or can get it with reasonable efforts.
|
||||
|
||||
You may not impose any further restrictions on the exercise of the
|
||||
rights granted or affirmed under this License. For example, you may
|
||||
not impose a license fee, royalty, or other charge for exercise of
|
||||
rights granted under this License, and you may not initiate litigation
|
||||
(including a cross-claim or counterclaim in a lawsuit) alleging that
|
||||
any patent claim is infringed by making, using, selling, offering for
|
||||
sale, or importing the Program or any portion of it.
|
||||
|
||||
11. Patents.
|
||||
|
||||
A "contributor" is a copyright holder who authorizes use under this
|
||||
License of the Program or a work on which the Program is based. The
|
||||
work thus licensed is called the contributor's "contributor version".
|
||||
|
||||
A contributor's "essential patent claims" are all patent claims
|
||||
owned or controlled by the contributor, whether already acquired or
|
||||
hereafter acquired, that would be infringed by some manner, permitted
|
||||
by this License, of making, using, or selling its contributor version,
|
||||
but do not include claims that would be infringed only as a
|
||||
consequence of further modification of the contributor version. For
|
||||
purposes of this definition, "control" includes the right to grant
|
||||
patent sublicenses in a manner consistent with the requirements of
|
||||
this License.
|
||||
|
||||
Each contributor grants you a non-exclusive, worldwide, royalty-free
|
||||
patent license under the contributor's essential patent claims, to
|
||||
make, use, sell, offer for sale, import and otherwise run, modify and
|
||||
propagate the contents of its contributor version.
|
||||
|
||||
In the following three paragraphs, a "patent license" is any express
|
||||
agreement or commitment, however denominated, not to enforce a patent
|
||||
(such as an express permission to practice a patent or covenant not to
|
||||
sue for patent infringement). To "grant" such a patent license to a
|
||||
party means to make such an agreement or commitment not to enforce a
|
||||
patent against the party.
|
||||
|
||||
If you convey a covered work, knowingly relying on a patent license,
|
||||
and the Corresponding Source of the work is not available for anyone
|
||||
to copy, free of charge and under the terms of this License, through a
|
||||
publicly available network server or other readily accessible means,
|
||||
then you must either (1) cause the Corresponding Source to be so
|
||||
available, or (2) arrange to deprive yourself of the benefit of the
|
||||
patent license for this particular work, or (3) arrange, in a manner
|
||||
consistent with the requirements of this License, to extend the patent
|
||||
license to downstream recipients. "Knowingly relying" means you have
|
||||
actual knowledge that, but for the patent license, your conveying the
|
||||
covered work in a country, or your recipient's use of the covered work
|
||||
in a country, would infringe one or more identifiable patents in that
|
||||
country that you have reason to believe are valid.
|
||||
|
||||
If, pursuant to or in connection with a single transaction or
|
||||
arrangement, you convey, or propagate by procuring conveyance of, a
|
||||
covered work, and grant a patent license to some of the parties
|
||||
receiving the covered work authorizing them to use, propagate, modify
|
||||
or convey a specific copy of the covered work, then the patent license
|
||||
you grant is automatically extended to all recipients of the covered
|
||||
work and works based on it.
|
||||
|
||||
A patent license is "discriminatory" if it does not include within
|
||||
the scope of its coverage, prohibits the exercise of, or is
|
||||
conditioned on the non-exercise of one or more of the rights that are
|
||||
specifically granted under this License. You may not convey a covered
|
||||
work if you are a party to an arrangement with a third party that is
|
||||
in the business of distributing software, under which you make payment
|
||||
to the third party based on the extent of your activity of conveying
|
||||
the work, and under which the third party grants, to any of the
|
||||
parties who would receive the covered work from you, a discriminatory
|
||||
patent license (a) in connection with copies of the covered work
|
||||
conveyed by you (or copies made from those copies), or (b) primarily
|
||||
for and in connection with specific products or compilations that
|
||||
contain the covered work, unless you entered into that arrangement,
|
||||
or that patent license was granted, prior to 28 March 2007.
|
||||
|
||||
Nothing in this License shall be construed as excluding or limiting
|
||||
any implied license or other defenses to infringement that may
|
||||
otherwise be available to you under applicable patent law.
|
||||
|
||||
12. No Surrender of Others' Freedom.
|
||||
|
||||
If conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot convey a
|
||||
covered work so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you may
|
||||
not convey it at all. For example, if you agree to terms that obligate you
|
||||
to collect a royalty for further conveying from those to whom you convey
|
||||
the Program, the only way you could satisfy both those terms and this
|
||||
License would be to refrain entirely from conveying the Program.
|
||||
|
||||
13. Remote Network Interaction.
|
||||
|
||||
A "Proxy Program" means a separate program which is specially designed to
|
||||
be used in conjunction with the covered work and interacts with it directly
|
||||
or indirectly through any kind of API (application programming interfaces),
|
||||
a computer network, an imitation of such network, or another Proxy Program
|
||||
itself.
|
||||
|
||||
Notwithstanding any other provision of this License, if you provide any user
|
||||
with an opportunity to interact with the covered work through a computer
|
||||
network, an imitation of such network, or any number of "Proxy Programs",
|
||||
you must prominently offer that user an opportunity to receive the
|
||||
Corresponding Source of the covered work and all Proxy Programs from a
|
||||
network server at no charge, through some standard or customary means of
|
||||
facilitating copying of software. The Corresponding Source for the covered
|
||||
work must be made available under the conditions of this License, and
|
||||
the Corresponding Source for all Proxy Programs must be made available
|
||||
under the conditions of either this License or any GPL-Compatible
|
||||
Free Software License, as described by the Free Software Foundation
|
||||
in their "GPL-Compatible License List".
|
||||
|
||||
14. Revised Versions of this License.
|
||||
|
||||
Vitastor Author may publish revised and/or new versions of
|
||||
the Vitastor Network Public License from time to time. Such new versions
|
||||
will be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the
|
||||
Program specifies that a certain numbered version of the Vitastor Network
|
||||
Public License "or any later version" applies to it, you have the
|
||||
option of following the terms and conditions either of that numbered
|
||||
version or of any later version. If the Program does not specify a version
|
||||
number of the Vitastor Network Public License, you may choose any version
|
||||
ever published.
|
||||
|
||||
Later license versions may give you additional or different
|
||||
permissions. However, no additional obligations are imposed on any
|
||||
author or copyright holder as a result of your choosing to follow a
|
||||
later version.
|
||||
|
||||
15. Disclaimer of Warranty.
|
||||
|
||||
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
||||
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
||||
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
|
||||
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
||||
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
|
||||
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
|
||||
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||
|
||||
16. Limitation of Liability.
|
||||
|
||||
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
||||
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
||||
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
|
||||
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
|
||||
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
|
||||
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
|
||||
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
||||
SUCH DAMAGES.
|
||||
|
||||
17. Interpretation of Sections 15 and 16.
|
||||
|
||||
If the disclaimer of warranty and limitation of liability provided
|
||||
above cannot be given local legal effect according to their terms,
|
||||
reviewing courts shall apply local law that most closely approximates
|
||||
an absolute waiver of all civil liability in connection with the
|
||||
Program, unless a warranty or assumption of liability accompanies a
|
||||
copy of the Program in return for a fee.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
state the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This program is free software: you can redistribute it and/or modify
|
||||
it under the terms of the Vitastor Network Public License as published by
|
||||
the Vitastor Author, either version 1 of the License, or
|
||||
(at your option) any later version.
|
||||
|
||||
This program is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
||||
Vitastor Network Public License for more details.
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If your software can interact with users remotely through a computer
|
||||
network, you should also make sure that it provides a way for users to
|
||||
get its source. For example, if your program is a web application, its
|
||||
interface could display a "Source" link that leads users to an archive
|
||||
of the code. There are many ways you could offer source, and different
|
||||
solutions will be better for different programs; see section 13 for the
|
||||
specific requirements.

EC+compression is a nightmare in Ceph, yeah :))
|
||||
|
||||
To calculate the average ratio between data chunks and parity chunks we
|
||||
calculate the number of PG chunks for each chunk role for each OSD:
|
||||
|
||||
{
|
||||
osd12: [ 18, 22, 17 ],
|
||||
osd7: [ 35, 22, 8 ],
|
||||
osd5: [ 6, 17, 27 ],
|
||||
osd6: [ 13, 12, 28 ],
|
||||
osd11: [ 13, 26, 20 ],
|
||||
osd3: [ 30, 20, 10 ],
|
||||
osd9: [ 8, 12, 26 ],
|
||||
osd10: [ 15, 23, 20 ],
|
||||
osd0: [ 22, 22, 14 ],
|
||||
osd2: [ 22, 16, 16 ],
|
||||
osd13: [ 29, 19, 13 ],
|
||||
osd8: [ 20, 18, 12 ],
|
||||
osd4: [ 8, 10, 28 ],
|
||||
osd1: [ 17, 17, 17 ]
|
||||
}
|
||||
|
||||
And now we can pick a pair of OSDs and determine the ratio by solving the following:
|
||||
|
||||
osd5 = 23*X + 27*Y = 3249728140
|
||||
osd13 = 48*X + 13*Y = 2991675992
|
||||
|
||||
=>
|
||||
|
||||
osd5 - 27/13*osd13 = 23*X - 27/13*48*X = -76.6923076923077*X = -2963752766.46154
|
||||
|
||||
=>
|
||||
|
||||
X = 38644720.1243731
|
||||
Y = (osd5-23*X)/27 = 87440725.0792377
|
||||
Y/X = 2.26268232239284 ~= 2.26
|
||||
|
||||
Which means that parity chunks are compressed ~2.26 times worse than data chunks.
|
||||
|
||||
Fine, let's try to optimize for it.
