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.
|
||||
|
||||
<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 GNU General Public License as published by
|
||||
the Free Software Foundation; either version 2 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
|
||||
GNU General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU General Public License along
|
||||
with this program; if not, write to the Free Software Foundation, Inc.,
|
||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
|
||||
|
||||
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:
|
||||
|
||||
Gnomovision version 69, Copyright (C) year name of author
|
||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, the commands you use may
|
||||
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
|
||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
||||
necessary. Here is a sample; alter the names:
|
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.

|
||||
|
||||
This General Public License does not permit incorporating your program into
|
||||
proprietary programs. If your program is a subroutine library, you may
|
||||
consider it more useful to permit linking proprietary applications with the
|
||||
library. If this is what you want to do, use the GNU Lesser General
|
||||
Public License instead of this License.

## Vitastor
|
||||
|
||||
[Read English version](README.md)
|
||||
|
||||
## Идея
|
||||
|
||||
Вернём былую скорость кластерному блочному хранилищу!
|
||||
|
||||
Vitastor - распределённая блочная SDS (программная СХД), прямой аналог Ceph RBD и
|
||||
внутренних СХД популярных облачных провайдеров. Однако, в отличие от них, Vitastor
|
||||
быстрый и при этом простой. Только пока маленький :-).
|
||||
|
||||
Vitastor архитектурно похож на Ceph, что означает атомарность и 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.
|
||||
|
||||
Vitastor нацелен на SSD и SSD+HDD кластеры с как минимум 10 Гбит/с сетью, поддерживает
|
||||
TCP и RDMA и на хорошем железе может достигать задержки 4 КБ чтения и записи на уровне ~0.1 мс,
|
||||
что примерно в 10 раз быстрее, чем Ceph и другие популярные программные СХД.
|
||||
|
||||
Vitastor поддерживает QEMU-драйвер, протоколы NBD и NFS, драйверы OpenStack, Proxmox, Kubernetes.
|
||||
Другие драйверы могут также быть легко реализованы.
|
||||

||||

Лицензия: VNPL 1.1 на серверный код и двойная VNPL 1.1 + GPL 2.0+ на клиентский.
|
||||
|
||||
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 Clustered Block Storage Fast Again.
|
||||
|
||||
Vitastor is a distributed block SDS, direct replacement of Ceph RBD and internal SDS's
|
||||
of public clouds. However, in contrast to them, Vitastor is fast and simple at the same time.
|
||||
The only thing is it's slightly young :-).
|
||||
|
||||
Vitastor is 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).
|
||||
|
||||
Vitastor targets SSD and SSD+HDD clusters with at least 10 Gbit/s network, supports
|
||||
TCP and RDMA and may achieve 4 KB read and write latency as low as ~0.1 ms
|
||||
with proper hardware which is ~10 times faster than other popular SDS's like Ceph
|
||||
or internal systems of public clouds.
|
||||
|
||||
Vitastor supports QEMU, NBD, NFS protocols, OpenStack, Proxmox, Kubernetes drivers.
|
||||
More drivers may be created easily.
|
||||

||||

with it ("Proxy Programs"). Proxy Programs may be made public not only under

the terms of the same license, but also under the terms of any GPL-Compatible
|
||||
Free Software License, as listed by the Free Software Foundation.
|
||||
This is a stricter copyleft license than the Affero GPL.
|
||||
|
||||
Please note that VNPL doesn't require you to open the code of proprietary
|

software running inside a VM if it's not specially designed to be used with
|

Vitastor.
|

|

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

its functionality to users without opensourcing all intermediary components
|

standing between the user and Vitastor or purchasing a commercial license
|
||||
from the author 😀.

Client libraries (cluster_client and so on) are dual-licensed under the same

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.

# Configuration Reference
|
||||
|
||||
Vitastor configuration consists of:
|
||||
- [Configuration parameters (key-value)](#parameter-reference)
|
||||
- [Pool configuration](config/pool.en.md)
|
||||
- [OSD placement tree configuration](config/pool.en.md#placement-tree)
|
||||
- [Separate OSD settings](config/pool.en.md#osd-settings)
|
||||
- [Inode configuration](config/inode.en.md) i.e. image metadata like name, size and parent reference
|
||||
|
||||
Configuration parameters can be set in 3 places:
|
||||
- Configuration file (`/etc/vitastor/vitastor.conf` or other path)
|
||||
- etcd key `/vitastor/config/global`. Most variables can be set there, but etcd
|
||||
connection parameters should obviously be set in the configuration file.
|
||||
- Command line of Vitastor components: OSD, mon, fio and QEMU options,
|
||||
OpenStack/Proxmox/etc configuration. The latter doesn't allow to set all
|
||||
variables directly, but it allows to override the configuration file and
|
||||
set everything you need inside it.
|
||||
|
||||
In the future, additional configuration methods may be added:
|
||||
- OSD superblock which will, by design, contain parameters related to the disk
|
||||
layout and to one specific OSD.
|
||||
- OSD-specific keys in etcd like `/vitastor/config/osd/<number>`.
|
||||
|
||||

# Конфигурация Vitastor
|
||||
|
||||
Конфигурация Vitastor состоит из:
|
||||
- [Параметров (ключ-значение)](#список-параметров)
|
||||
- [Настроек пулов](config/pool.ru.md)
|
||||
- [Настроек дерева OSD](config/pool.ru.md#дерево-размещения)
|
||||
- [Настроек отдельных OSD](config/pool.ru.md#настройки-osd)
|
||||
- [Настроек инодов](config/inode.ru.md), т.е. метаданных образов, таких, как имя, размер и ссылки на
|
||||
родительский образ
|
||||
|
||||
Параметры конфигурации могут задаваться в 3 местах:
|
||||
- Файле конфигурации (`/etc/vitastor/vitastor.conf` или по другому пути)
|
||||
- Ключе в etcd `/vitastor/config/global`. Большая часть параметров может
|
||||
задаваться там, кроме, естественно, самих параметров соединения с etcd,
|
||||
которые должны задаваться в файле конфигурации
|
||||
- В командной строке компонентов Vitastor: OSD, монитора, опциях fio и QEMU,
|
||||
настроек OpenStack, Proxmox и т.п. Последние, как правило, не включают полный
|
||||
набор параметров напрямую, но разрешают определить путь к файлу конфигурации
|
||||
и задать любые параметры в нём.
|
||||
|
||||
В будущем также могут быть добавлены другие способы конфигурации:
|
||||
- Суперблок OSD, в котором будут храниться параметры OSD, связанные с дисковым
|
||||
форматом и с этим конкретным OSD.
|
||||
- OSD-специфичные ключи в etcd типа `/vitastor/config/osd/<номер>`.
|
||||
|
||||
## Список параметров
|
||||
|
||||
- [Общие](config/common.ru.md)
|
||||
- [Сеть](config/network.ru.md)
|
||||
- [Глобальные дисковые параметры](config/layout-cluster.ru.md)
|
||||
- [Дисковые параметры OSD](config/layout-osd.ru.md)
|
||||
- [Прочие параметры OSD](config/osd.ru.md)
|
||||
- [Параметры мониторов](config/monitor.ru.md)

specified in a JSON array `["10.0.115.10:2379/v3","10.0.115.11:2379/v3"]`.
|
||||
Note that https is not supported for etcd connections yet.
|
||||
|
||||
## etcd_prefix
|
||||
|
||||
- Type: string
|
||||
- Default: /vitastor
|
||||
|
||||
Prefix for all keys in etcd used by Vitastor. You can change prefix and, for
|
||||
example, use a single etcd cluster for multiple Vitastor clusters.
|
||||
|
||||
## log_level
|
||||
|
||||
- Type: integer
|
||||
- Default: 0

# Image metadata in etcd
|
||||
|
||||
Image list is stored in etcd in `/vitastor/config/inode/<pool>/<inode>` keys.
|
||||
|
||||
You can even create images manually:
|
||||
|
||||
```
|
||||
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.
|
||||
|
||||
vitastor-cli, K8s, OpenStack and other drivers also store the reverse mapping in `/vitastor/index/image/<name>` keys
|
||||
in JSON format: `{"id":<inode>,"pool_id":<pool>}` and ID counters in `/vitastor/index/maxid/<pool>` as numbers
|
||||
to simplify ID generation.

[Read in English](inode.en.md)
|

|

# Метаданные образов в etcd
|
||||
|
||||
Список образов хранится в etcd в ключах `/vitastor/config/inode/<pool>/<inode>`.
|
||||
|
||||
Вы можете даже создавать образы вручную:
|
||||
|
||||
```
|
||||
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.
|
||||
|
||||
vitastor-cli и драйвера K8s, OpenStack и т.п. также хранят обратный маппинг в ключах `/vitastor/index/image/<name>`
|
||||
в JSON-формате: `{"id":<inode>,"pool_id":<pool>}` и счётчики ID `/vitastor/index/maxid/<pool>` в виде просто чисел
|
||||
для упрощения генерации ID новых образов.

# Cluster-Wide Disk Layout Parameters
|
||||
|
||||
These parameters apply to clients and OSDs, are fixed at the moment of OSD drive
|
||||
initialization and can't be changed after it without losing data.
|
||||
|
||||
- [block_size](#block_size)
|
||||
- [bitmap_granularity](#bitmap_granularity)
|
||||
- [immediate_commit](#immediate_commit)
|
||||
- [client_dirty_limit](#client_dirty_limit)
|
||||
|
||||
## block_size
|
||||
|
||||
- Type: integer
|
||||
- Default: 131072
|
||||
|
||||
Size of objects (data blocks) into which all physical and virtual drives are
|
||||
subdivided in Vitastor. One of current main settings in Vitastor, affects
|
||||
memory usage, write amplification and I/O load distribution effectiveness.
|
||||
|
||||
Recommended default block size is 128 KB for SSD and 4 MB for HDD. In fact,
|
||||
it's possible to use 4 MB for SSD too - it will lower memory usage, but
|
||||
may increase average WA and reduce linear performance.
|
||||
|
||||
OSDs with different block sizes (for example, SSD and SSD+HDD OSDs) can
|
||||
currently coexist in one etcd instance only within separate Vitastor
|
||||
clusters with different etcd_prefix'es.
|
||||
|
||||
Also block size can't be changed after OSD initialization without losing
|
||||
data.
|
||||
|
||||
You must always specify block_size in etcd in /vitastor/config/global if
|
||||
you change it so all clients can know about it.
|
||||
|
||||
OSD memory usage is roughly (SIZE / BLOCK * 68 bytes) which is roughly
|
||||
544 MB per 1 TB of used disk space with the default 128 KB block size.
|
||||
|
||||
## bitmap_granularity
|
||||
|
||||
- Type: integer
|
||||
- Default: 4096
|
||||
|
||||
Required virtual disk write alignment ("sector size"). Must be a multiple
|
||||
of disk_alignment. It's called bitmap granularity because Vitastor tracks
|
||||
an allocation bitmap for each object containing 2 bits per each
|
||||
(bitmap_granularity) bytes.
|
||||
|
||||
This parameter can't be changed after OSD initialization without losing
|
||||
data. Also it's fixed for the whole Vitastor cluster i.e. two different
|
||||
values can't be used in a single Vitastor cluster.
|
||||
|
||||
Clients MUST be aware of this parameter value, so put it into etcd key
|
||||
/vitastor/config/global if you change it for any reason.
|
||||
|
||||
## immediate_commit
|
||||
|
||||
- Type: string
|
||||
- Default: false
|
||||
|
||||
Another parameter which is really important for performance.
|
||||
|
||||
Desktop SSDs are very fast (100000+ iops) for simple random writes
|
||||
without cache flush. However, they are really slow (only around 1000 iops)
|
||||
if you try to fsync() each write, that is, when you want to guarantee that
|
||||
each change gets immediately persisted to the physical media.
|
||||
|
||||
Server-grade SSDs with "Advanced/Enhanced Power Loss Protection" or with
|
||||
"Supercapacitor-based Power Loss Protection", on the other hand, are equally
|
||||
fast with and without fsync because their cache is protected from sudden
|
||||
power loss by a built-in supercapacitor-based "UPS".
|
||||
|
||||
Some software-defined storage systems always fsync each write and thus are
|
||||
really slow when used with desktop SSDs. Vitastor, however, can also
|
||||
efficiently utilize desktop SSDs by postponing fsync until the client calls
|
||||
it explicitly.
|
||||
|
||||
This is what this parameter regulates. When it's set to "all" the whole
|
||||
Vitastor cluster commits each change to disks immediately and clients just
|
||||
ignore fsyncs because they know for sure that they're unneeded. This reduces
|
||||
the amount of network roundtrips performed by clients and improves
|
||||
performance. So it's always better to use server grade SSDs with
|
||||
supercapacitors even with Vitastor, especially given that they cost only
|
||||
a bit more than desktop models.
|
||||
|
||||
There is also a common SATA SSD (and HDD too!) firmware bug (or feature)
|
||||
that makes server SSDs which have supercapacitors slow with fsync. To check
|
||||
if your SSDs are affected, compare benchmark results from `fio -name=test
|
||||
-ioengine=libaio -direct=1 -bs=4k -rw=randwrite -iodepth=1` with and without
|
||||
`-fsync=1`. Results should be the same. If fsync=1 result is worse you can
|
||||
try to work around this bug by "disabling" drive write-back cache by running
|
||||
`hdparm -W 0 /dev/sdXX` or `echo write through > /sys/block/sdXX/device/scsi_disk/*/cache_type`
|
||||
(IMPORTANT: don't mistake it with `/sys/block/sdXX/queue/write_cache` - it's
|
||||
unsafe to change by hand). The same may apply to newer HDDs with internal
|
||||
SSD cache or "media-cache" - for example, a lot of Seagate EXOS drives have
|
||||
it (they have internal SSD cache even though it's not stated in datasheets).
|
||||
|
||||
This parameter must be set both in etcd in /vitastor/config/global and in
|
||||
OSD command line or configuration. Setting it to "all" or "small" requires
|
||||
enabling disable_journal_fsync and disable_meta_fsync, setting it to "all"
|
||||
also requires enabling disable_data_fsync.
|
||||
|
||||
TLDR: For optimal performance, set immediate_commit to "all" if you only use
|
||||
SSDs with supercapacitor-based power loss protection (nonvolatile
|
||||
write-through cache) for both data and journals in the whole Vitastor
|
||||
cluster. Set it to "small" if you only use such SSDs for journals. Leave
|
||||
empty if your drives have write-back cache.
|
||||
|
||||
## client_dirty_limit
|
||||
|
||||
- Type: integer
|
||||
- Default: 33554432
|
||||
|
||||
Without immediate_commit=all this parameter sets the limit of "dirty"
|
||||
(not committed by fsync) data allowed by the client before forcing an
|
||||
additional fsync and committing the data. Also note that the client always
|
||||
holds a copy of uncommitted data in memory so this setting also affects
|
||||
RAM usage of clients.
|
||||
|
||||
This parameter doesn't affect OSDs themselves.

# Дисковые параметры уровня кластера
|
||||
|
||||
Данные параметры используются клиентами и OSD, задаются в момент инициализации
|
||||
диска OSD и не могут быть изменены после этого без потери данных.
|
||||
|
||||
- [block_size](#block_size)
|
||||
- [bitmap_granularity](#bitmap_granularity)
|
||||
- [immediate_commit](#immediate_commit)
|
||||
- [client_dirty_limit](#client_dirty_limit)
|
||||
|
||||
## block_size
|
||||
|
||||
- Тип: целое число
|
||||
- Значение по умолчанию: 131072
|
||||
|
||||
Размер объектов (блоков данных), на которые делятся физические и виртуальные
|
||||
диски в Vitastor. Одна из ключевых на данный момент настроек, влияет на
|
||||
потребление памяти, объём избыточной записи (write amplification) и
|
||||
эффективность распределения нагрузки по OSD.
|
||||
|
||||
Рекомендуемые по умолчанию размеры блока - 128 килобайт для SSD и 4
|
||||
мегабайта для HDD. В принципе, для SSD можно тоже использовать 4 мегабайта,
|
||||
это понизит использование памяти, но ухудшит распределение нагрузки и в
|
||||
среднем увеличит WA.
|
||||
|
||||
OSD с разными размерами блока (например, SSD и SSD+HDD OSD) на данный
|
||||
момент могут сосуществовать в рамках одного etcd только в виде двух независимых
|
||||
кластеров Vitastor с разными etcd_prefix.
|
||||
|
||||
Также размер блока нельзя менять после инициализации OSD без потери данных.
|
||||
|
||||
Если вы меняете размер блока, обязательно прописывайте его в etcd в
|
||||
/vitastor/config/global, дабы все клиенты его знали.
|
||||
|
||||
Потребление памяти OSD составляет примерно (РАЗМЕР / БЛОК * 68 байт),
|
||||
т.е. примерно 544 МБ памяти на 1 ТБ занятого места на диске при
|
||||
стандартном 128 КБ блоке.
|
||||
|
||||
## bitmap_granularity
|
||||
|
||||
- Тип: целое число
|
||||
- Значение по умолчанию: 4096
|
||||
|
||||
Требуемое выравнивание записи на виртуальные диски (размер их "сектора").
|
||||
Должен быть кратен disk_alignment. Называется гранулярностью битовой карты
|
||||
потому, что Vitastor хранит битовую карту для каждого объекта, содержащую
|
||||
по 2 бита на каждые (bitmap_granularity) байт.
|
||||
|
||||
Данный параметр нельзя менять после инициализации OSD без потери данных.
|
||||
Также он фиксирован для всего кластера Vitastor, т.е. разные значения
|
||||
не могут сосуществовать в одном кластере.
|
||||
|
||||
Клиенты ДОЛЖНЫ знать правильное значение этого параметра, так что если вы
|
||||
его меняете, обязательно прописывайте изменённое значение в etcd в ключ
|
||||
/vitastor/config/global.
|
||||
|
||||
## immediate_commit
|
||||
|
||||
- Тип: строка
|
||||
- Значение по умолчанию: false
|
||||
|
||||
Ещё один важный для производительности параметр.
|
||||
|
||||
Модели SSD для настольных компьютеров очень быстрые (100000+ операций в
|
||||
секунду) при простой случайной записи без сбросов кэша. Однако они очень
|
||||
медленные (всего порядка 1000 iops), если вы пытаетесь сбрасывать кэш после
|
||||
каждой записи, то есть, если вы пытаетесь гарантировать, что каждое
|
||||
изменение физически записывается в энергонезависимую память.
|
||||
|
||||
С другой стороны, серверные SSD с конденсаторами - функцией, называемой
|
||||
"Advanced/Enhanced Power Loss Protection" или просто "Supercapacitor-based
|
||||
Power Loss Protection" - одинаково быстрые и со сбросом кэша, и без
|
||||
него, потому что их кэш защищён от потери питания встроенным "источником
|
||||
бесперебойного питания" на основе суперконденсаторов и на самом деле они
|
||||
его никогда не сбрасывают.
|
||||
|
||||
Некоторые программные СХД всегда сбрасывают кэши дисков при каждой записи
|
||||
и поэтому работают очень медленно с настольными SSD. Vitastor, однако, может
|
||||
откладывать fsync до явного его вызова со стороны клиента и таким образом
|
||||
эффективно утилизировать настольные SSD.
|
||||
|
||||
Данный параметр влияет как раз на это. Когда он установлен в значение "all",
|
||||
весь кластер Vitastor мгновенно фиксирует каждое изменение на физические
|
||||
носители и клиенты могут просто игнорировать запросы fsync, т.к. они точно
|
||||
знают, что fsync-и не нужны. Это уменьшает число необходимых обращений к OSD
|
||||
по сети и улучшает производительность. Поэтому даже с Vitastor лучше всегда
|
||||
использовать только серверные модели SSD с суперконденсаторами, особенно
|
||||
учитывая то, что стоят они ненамного дороже настольных.
|
||||
|
||||
Также в прошивках SATA SSD (и даже HDD!) очень часто встречается либо баг,
|
||||
либо просто особенность логики, из-за которой серверные SSD, имеющие
|
||||
конденсаторы и защиту от потери питания, всё равно медленно работают с
|
||||
fsync. Чтобы понять, подвержены ли этой проблеме ваши SSD, сравните
|
||||
результаты тестов `fio -name=test -ioengine=libaio -direct=1 -bs=4k
|
||||
-rw=randwrite -iodepth=1` без и с опцией `-fsync=1`. Результаты должны
|
||||
быть одинаковые. Если результат с `fsync=1` хуже, вы можете попробовать
|
||||
обойти проблему, "отключив" кэш записи диска командой `hdparm -W 0 /dev/sdXX`
|
||||
либо `echo write through > /sys/block/sdXX/device/scsi_disk/*/cache_type`
|
||||
(ВАЖНО: не перепутайте с `/sys/block/sdXX/queue/write_cache` - этот параметр
|
||||
менять руками небезопасно). Такая же проблема может встречаться и в новых
|
||||
HDD-дисках с внутренним SSD или "медиа" кэшем - например, она встречается во
|
||||
многих дисках Seagate EXOS (у них есть внутренний SSD-кэш, хотя это и не
|
||||
указано в спецификациях).
|
||||
|
||||
Данный параметр нужно указывать и в etcd в /vitastor/config/global, и в
|
||||
командной строке или конфигурации OSD. Значения "all" и "small" требуют
|
||||
включения disable_journal_fsync и disable_meta_fsync, значение "all" также
|
||||
требует включения disable_data_fsync.
|
||||
|
||||
Итого, вкратце: для оптимальной производительности установите
|
||||
immediate_commit в значение "all", если вы используете в кластере только SSD
|
||||
с суперконденсаторами и для данных, и для журналов. Если вы используете
|
||||
такие SSD для всех журналов, но не для данных - можете установить параметр
|
||||
в "small". Если и какие-то из дисков журналов имеют волатильный кэш записи -
|
||||
оставьте параметр пустым.
|
||||
|
||||
## client_dirty_limit
|
||||
|
||||
- Тип: целое число
|
||||
- Значение по умолчанию: 33554432
|
||||
|
||||
При работе без immediate_commit=all - это лимит объёма "грязных" (не
|
||||
зафиксированных fsync-ом) данных, при достижении которого клиент будет
|
||||
принудительно вызывать fsync и фиксировать данные. Также стоит иметь в виду,
|
||||
что в этом случае до момента fsync клиент хранит копию незафиксированных
|
||||
данных в памяти, то есть, настройка влияет на потребление памяти клиентами.
|
||||
|
||||
Параметр не влияет на сами OSD.

|
||||
|
||||
## data_device
|
||||
|
||||
- Type: string
|
||||
|
||||
Path to the block device to use for data. It's highly recommendded to use
|
||||
stable paths for all device names: `/dev/disk/by-partuuid/xxx...` instead
|
||||
of just `/dev/sda` or `/dev/nvme0n1` to not mess up after server restart.
|
||||
Files can also be used instead of block devices, but this is implemented
|
||||
only for testing purposes and not for production.
|
||||
|
||||
## meta_device
|
||||
|
||||
- Type: string
|
||||
|
||||
Path to the block device to use for the metadata. Metadata must be on a fast
|
||||
SSD or performance will suffer. If this option is skipped, `data_device` is
|
||||
used for the metadata.
|
||||
|
||||
## journal_device
|
||||
|
||||
- Type: string
|
||||
|
||||
Path to the block device to use for the journal. Journal must be on a fast
|
||||
SSD or performance will suffer. If this option is skipped, `meta_device` is
|
||||
used for the journal, and if it's also empty, journal is put on
|
||||
`data_device`. It's almost always fine to put metadata and journal on the
|
||||
same device, in this case you only need to set `meta_device`.
|
||||
|
||||
## journal_offset
|
||||
|
||||
- Type: integer
|
||||
- Default: 0
|
||||
|
||||
Offset on the device in bytes where the journal is stored.
|
||||
|
||||
## journal_size
|
||||
|
||||
- Type: integer
|
||||
|
||||
Journal size in bytes. By default, all available space between journal_offset
|
||||
and data_offset, meta_offset or the end of the journal device is used.
|
||||
Large journals aren't needed in SSD-only setups, 32 MB is always enough.
|
||||
In SSD+HDD setups it is beneficial to use larger journals (for example, 1 GB)
|
||||
and enable [throttle_small_writes](osd.en.md#throttle_small_writes).
|
||||
|
||||
## meta_offset
|
||||
|
||||
- Type: integer
|
||||
- Default: 0
|
||||
|
||||
Offset on the device in bytes where the metadata area is stored.
|
||||
Again, set it to something if you colocate metadata with journal or data.
|
||||
|
||||
## data_offset
|
||||
|
||||
- Type: integer
|
||||
- Default: 0
|
||||
|
||||
Offset on the device in bytes where the data area is stored.
|
||||
Again, set it to something if you colocate data with journal or metadata.
|
||||
|
||||
## data_size
|
||||
|
||||
- Type: integer
|
||||
|
||||
Data area size in bytes. By default, the whole data device up to the end
|
||||
will be used for the data area, but you can restrict it if you want to use
|
||||
a smaller part. Note that there is no option to set metadata area size -
|
||||
it's derived from the data area size.
|
||||
|
||||
## meta_block_size
|
||||
|
||||
- Type: integer
|
||||
- Default: 4096
|
||||
|
||||
Physical block size of the metadata device. 4096 for most current
|
||||
HDDs and SSDs.
|
||||
|
||||
## journal_block_size
|
||||
|
||||
- Type: integer
|
||||
- Default: 4096
|
||||
|
||||
Physical block size of the journal device. Must be a multiple of
|
||||
`disk_alignment`. 4096 for most current HDDs and SSDs.
|
||||
|
||||
## disable_data_fsync
|
||||
|
||||
- Type: boolean
|
||||
- Default: false
|
||||
|
||||
Do not issue fsyncs to the data device, i.e. do not flush its cache.
|
||||
Safe ONLY if your data device has write-through cache. If you disable
|
||||
the cache yourself using `hdparm` or `scsi_disk/cache_type` then make sure
|
||||
that the cache disable command is run every time before starting Vitastor
|
||||
OSD, for example, in the systemd unit. See also `immediate_commit` option
|
||||
for the instructions to disable cache and how to benefit from it.
|
||||
|
||||
## disable_meta_fsync
|
||||
|
||||
- Type: boolean
|
||||
- Default: false
|
||||
|
||||
Same as disable_data_fsync, but for the metadata device. If the metadata
|
||||
device is not set or if the data device is used for the metadata the option
|
||||
is ignored and disable_data_fsync value is used instead of it.
|
||||
|
||||
## disable_journal_fsync
|
||||
|
||||
- Type: boolean
|
||||
- Default: false
|
||||
|
||||
Same as disable_data_fsync, but for the journal device. If the journal
|
||||
device is not set or if the metadata device is used for the journal the
|
||||
option is ignored and disable_meta_fsync value is used instead of it. If
|
||||
the same device is used for data, metadata and journal the option is also
|
||||
ignored and disable_data_fsync value is used instead of it.
|
||||
|
||||
## disable_device_lock
|
||||
|
||||
- Type: boolean
|
||||
- Default: false
|
||||
|
||||
Do not lock data, metadata and journal block devices exclusively with
|
||||
flock(). Though it's not recommended, but you can use it you want to run
|
||||
multiple OSD with a single device and different offsets, without using
|
||||
partitions.
|
||||
|
||||
## disk_alignment
|
||||
|
||||
- Type: integer
|
||||
- Default: 4096
|
||||
|
||||
Required physical disk write alignment. Most current SSD and HDD drives
|
||||
use 4 KB physical sectors even if they report 512 byte logical sector
|
||||
size, so 4 KB is a good default setting.
|
||||
|
||||
Note, however, that physical sector size also affects WA, because with block
|
||||
devices it's impossible to write anything smaller than a block. So, when
|
||||
Vitastor has to write a single metadata entry that's only about 32 bytes in
|
||||
size, it actually has to write the whole 4 KB sector.
|
||||
|
||||
Because of this it can actually be beneficial to use SSDs which work well
|
||||
with 512 byte sectors and use 512 byte disk_alignment, journal_block_size
|
||||
and meta_block_size. But the only SSD that may fit into this category is
|
||||
Intel Optane (probably, not tested yet).
|
||||
|
||||
Clients don't need to be aware of disk_alignment, so it's not required to
|
||||
put a modified value into etcd key /vitastor/config/global.

|
||||
|
||||
## data_device
|
||||
|
||||
- Тип: строка
|
||||
|
||||
Путь к диску (блочному устройству) для хранения данных. Крайне рекомендуется
|
||||
использовать стабильные пути: `/dev/disk/by-partuuid/xxx...` вместо простых
|
||||
`/dev/sda` или `/dev/nvme0n1`, чтобы пути не могли спутаться после
|
||||
перезагрузки сервера. Также вместо блочных устройств можно указывать файлы,
|
||||
но это реализовано только для тестирования, а не для боевой среды.
|
||||
|
||||
## meta_device
|
||||
|
||||
- Тип: строка
|
||||
|
||||
Путь к диску метаданных. Метаданные должны располагаться на быстром
|
||||
SSD-диске, иначе производительность пострадает. Если эта опция не указана,
|
||||
для метаданных используется `data_device`.
|
||||
|
||||
## journal_device
|
||||
|
||||
- Тип: строка
|
||||
|
||||
Путь к диску журнала. Журнал должен располагаться на быстром SSD-диске,
|
||||
иначе производительность пострадает. Если эта опция не указана,
|
||||
для журнала используется `meta_device`, если же пуста и она, журнал
|
||||
располагается на `data_device`. Нормально располагать журнал и метаданные
|
||||
на одном устройстве, в этом случае достаточно указать только `meta_device`.
|
||||
|
||||
## journal_offset
|
||||
|
||||
- Тип: целое число
|
||||
- Значение по умолчанию: 0
|
||||
|
||||
Смещение на устройстве в байтах, по которому располагается журнал.
|
||||
|
||||
## journal_size
|
||||
|
||||
- Тип: целое число
|
||||
|
||||
Размер журнала в байтах. По умолчанию для журнала используется всё доступное
|
||||
место между journal_offset и data_offset, meta_offset или концом диска.
|
||||
В SSD-кластерах большие журналы не нужны, достаточно 32 МБ. В гибридных
|
||||
(SSD+HDD) кластерах осмысленно использовать больший размер журнал (например, 1 ГБ)
|
||||
и включить [throttle_small_writes](osd.ru.md#throttle_small_writes).
|
||||
|
||||
## meta_offset
|
||||
|
||||
- Тип: целое число
|
||||
- Значение по умолчанию: 0
|
||||
|
||||
Смещение на устройстве в байтах, по которому располагаются метаданные.
|
||||
Эту опцию нужно задать, если метаданные у вас хранятся на том же
|
||||
устройстве, что данные или журнал.
|
||||
|
||||
## data_offset
|
||||
|
||||
- Тип: целое число
|
||||
- Значение по умолчанию: 0
|
||||
|
||||
Смещение на устройстве в байтах, по которому располагаются данные.
|
||||
Эту опцию нужно задать, если данные у вас хранятся на том же
|
||||
устройстве, что метаданные или журнал.
|
||||
|
||||
## data_size
|
||||
|
||||
- Тип: целое число
|
||||
|
||||
Размер области данных в байтах. По умолчанию под данные будет использована
|
||||
вся доступная область устройства данных до конца устройства, но вы можете
|
||||
использовать эту опцию, чтобы ограничить её меньшим размером. Заметьте, что
|
||||
опции размера области метаданных нет - она вычисляется из размера области
|
||||
данных автоматически.
|
||||
|
||||
## meta_block_size
|
||||
|
||||
- Тип: целое число
|
||||
- Значение по умолчанию: 4096
|
||||
|
||||
Размер физического блока устройства метаданных. 4096 для большинства
|
||||
современных SSD и HDD.
|
||||
|
||||
## journal_block_size
|
||||
|
||||
- Тип: целое число
|
||||
- Значение по умолчанию: 4096
|
||||
|
||||
Размер физического блока устройства журнала. Должен быть кратен
|
||||
`disk_alignment`. 4096 для большинства современных SSD и HDD.
|
||||
|
||||
## disable_data_fsync
|
||||
|
||||
- Тип: булево (да/нет)
|
||||
- Значение по умолчанию: false
|
||||
|
||||
Не отправлять fsync-и устройству данных, т.е. не сбрасывать его кэш.
|
||||
Безопасно, ТОЛЬКО если ваше устройство данных имеет кэш со сквозной
|
||||
записью (write-through). Если вы отключаете кэш через `hdparm` или
|
||||
`scsi_disk/cache_type`, то удостоверьтесь, что команда отключения кэша
|
||||
выполняется перед каждым запуском Vitastor OSD, например, в systemd unit-е.
|
||||
Смотрите также опцию `immediate_commit` для инструкций по отключению кэша
|
||||
и о том, как из этого извлечь выгоду.
|
||||
|
||||
## disable_meta_fsync
|
||||
|
||||
- Тип: булево (да/нет)
|
||||
- Значение по умолчанию: false
|
||||
|
||||
То же, что disable_data_fsync, но для устройства метаданных. Если устройство
|
||||
метаданных не задано или если оно равно устройству данных, значение опции
|
||||
игнорируется и вместо него используется значение опции disable_data_fsync.
|
||||
|
||||
## disable_journal_fsync
|
||||
|
||||
- Тип: булево (да/нет)
|
||||
- Значение по умолчанию: false
|
||||
|
||||
То же, что disable_data_fsync, но для устройства журнала. Если устройство
|
||||
журнала не задано или если оно равно устройству метаданных, значение опции
|
||||
игнорируется и вместо него используется значение опции disable_meta_fsync.
|
||||
Если одно и то же устройство используется и под данные, и под журнал, и под
|
||||
метаданные - значение опции также игнорируется и вместо него используется
|
||||
значение опции disable_data_fsync.
|
||||
|
||||
## disable_device_lock
|
||||
|
||||
- Тип: булево (да/нет)
|
||||
- Значение по умолчанию: false
|
||||
|
||||
Не блокировать устройства данных, метаданных и журнала от открытия их
|
||||
другими OSD с помощью flock(). Так делать не рекомендуется, но теоретически
|
||||
вы можете это использовать, чтобы запускать несколько OSD на одном
|
||||
устройстве с разными смещениями и без использования разделов.
|
||||
|
||||
## disk_alignment
|
||||
|
||||
- Тип: целое число
|
||||
- Значение по умолчанию: 4096
|
||||
|
||||
Требуемое выравнивание записи на физические диски. Почти все современные
|
||||
SSD и HDD диски используют 4 КБ физические секторы, даже если показывают
|
||||
логический размер сектора 512 байт, поэтому 4 КБ - хорошее значение по
|
||||
умолчанию.
|
||||
|
||||
Однако стоит понимать, что физический размер сектора тоже влияет на
|
||||
избыточную запись (WA), потому что ничего меньше блока (сектора) на блочное
|
||||
устройство записать невозможно. Таким образом, когда Vitastor-у нужно
|
||||
записать на диск всего лишь одну 32-байтную запись метаданных, фактически
|
||||
приходится перезаписывать 4 КБ сектор целиком.
|
||||
|
||||
Поэтому, на самом деле, может быть выгодно найти SSD, хорошо работающие с
|
||||
меньшими, 512-байтными, блоками и использовать 512-байтные disk_alignment,
|
||||
journal_block_size и meta_block_size. Однако единственные SSD, которые
|
||||
теоретически могут попасть в эту категорию - это Intel Optane (но и это
|
||||
пока не проверялось автором).
|
||||
|
||||
Клиентам не обязательно знать про disk_alignment, так что помещать значение
|
||||
этого параметра в etcd в /vitastor/config/global не нужно.

Levels for the placement tree. You can define arbitrary tree levels by
|
||||
defining them in this parameter. The configuration parameter value should
|
||||
contain a JSON object with level names as keys and integer priorities as
|
||||
values. Smaller priority means higher level in tree. For example,
|
||||
"datacenter" should have smaller priority than "osd". "host" and "osd"
|
||||
levels are always predefined and can't be removed. If one of them is not
|
||||
present in the configuration, then it is defined with the default priority
|
||||
(100 for "host", 101 for "osd").

Определения уровней для дерева размещения OSD. Вы можете определять
|
||||
произвольные уровни, помещая их в данный параметр конфигурации. Значение
|
||||
параметра должно содержать JSON-объект, ключи которого будут являться
|
||||
названиями уровней, а значения - целочисленными приоритетами. Меньшие
|
||||
приоритеты соответствуют верхним уровням дерева. Например, уровень
|
||||
"датацентр" должен иметь меньший приоритет, чем "OSD". Уровни с названиями
|
||||
"host" и "osd" являются предопределёнными и не могут быть удалены. Если
|
||||
один из них отсутствует в конфигурации, он доопределяется с приоритетом по
|
||||
умолчанию (100 для уровня "host", 101 для "osd").
