Vitaliy Filippov c777a0041a Release 1.4.4
A couple of fixes for EC pools

- Fix a segfault possible on partial EC overwrite in 1234 -> 5030 rebalance scenario
- Fix two problems leading to EC pools stalling on rebalance & parallel sudden stops
  of OSDs, for example during a sudden poweroff of a host:
  - Recovery auto-tuning (1.4.0 feature) could apply too large delays and stall
    the EC journal - fixed by limiting delays with a new recovery_tune_sleep_cutoff_us
    parameter (10 seconds by default) and applying recovery pauses before write
    operations, not after them, to not occupy space in the journal for long time
  - Dynamic journal space reservation (1.3.0 feature) wasn't accounting new writes
    when checking the limit so OSDs could still fill the journal fully and stall -
    fixed by including new writes into the limit
- Print etcd dbSize instead of dbSizeInUse in status

Vitaliy Filippov 27e9f244ec Release 1.4.3
Hotfix for hotfix O:-)

- "Write stall fix" was incomplete and EC write stalls could
  continue even on 1.4.2. Now they're finally fixed O:-)
- Make monitor ignore statistics of stopped OSDs. Previously if you stopped all
  OSDs the last total I/O numbers would remain the same indefinitely

Vitaliy Filippov 016115c0d4 Release 1.4.2
- Log to systemd by default
- Fix excessive autosyncs after every operation with disabled immediate_commit (introduced in 1.1.0)
- Fix a possible write stall with EC due to the lack of OSD wakeup after stabilizing previous writes
- Change sync operation semantics as a final fix to possible write stalls with EC and disabled immediate_commit
- Sync after deleting data in CLI rm / rm-data if immediate_commit is disabled
- Fix OSDs ignoring syncs & autosyncs for delete operations
- Fix OSD space reporting sometimes adding garbage zeros for deleted inodes (causing extra pool/stats etcd keys for deleted pools)
- Speed up monitor failover - change default etcd_mon_ttl from 30 to 5 seconds
- Speed up operation retries - change default up_wait_retry_interval to 50 ms
- Add patch for libvirt 9.10

Vitaliy Filippov 1cec62d25d Sync only completed writes
Should be a final remaining fix to EC + non-capacitor (non-immediate-commit) write hangs :).

First it was breaking non-EC ("instantly stable") writes because they sometimes
complete out of order which was leading to the following error:

terminate called after throwing an instance of 'std::runtime_error'
  what():  BUG: Unexpected dirty_entry 1000000000001:29480000 v65540 unstable state during flush: 0x151

But it is easily fixed by scanning previous and next dirty_entries in mark_stable.

Vitaliy Filippov 5280d1d561 Release 1.4.0
New features:
- Intelligent recovery/rebalance speed auto-tuning to reduce its impact on clients (see README -> Features)
- Auto-restoration of dead VDUSE daemons in CSI plugin
- Add vitastor-disk update-sb command
- Update QEMU for Debian Bookworm to 8.1 and use it for CSI plugin

Bug fixes:
- Fix pools SOMETIMES staying inactive after stopping a node due to OSDs not reacting
  to PG state changes caused by incorrect full reload of state from etcd on reconnection
- Make monitors retry pool configuration changes quickier which fixes them being unable
  to apply changes when an ongoing rebalance is quickly making a lot of PGs clean
- Fix CSI plugin not accepting array of strings as etcd address in /etc/vitastor/vitastor.conf
- Allow multiple interfaces with the same IP address, for "simple routed" full mesh network
- Do not ignore loopback addresses for OSD network (to make ECMP setups with frr possible)
- Fix a rare client crash during OSD reconnections
- Only treat data partitions as existing OSDs in vitastor-disk prepare
- Remove etcd parameter from default command examples
- Fix reported free space sometimes changing non-immediately after deletion of data from OSDs
- Fix a possible OSD crash on print_slow when bs_op is NULL
- Use the same etcd_ws_keepalive_interval in mon as in OSD
- Fix mon not using values from config when /config/global is not present
- Remove pve-storage-portal-dns-list format for vitastor_etcd_address
- Parse log_level in cluster_client
- Fix vitastor-nbd image existence check not working because of non-zeroed inode_watch fields
- Do not warn on EPIPE in client unless log_level is raised explicitly
- Fix incorrect error in CSI when searching for the device in /sys
- Remove 2 last prints to stdout in etcd_state_client
- Fix a possible OSD crash when checking corrupted journal entries

Vitaliy Filippov f757a35a8d Retry PG changes without re-running lpsolve when pool configuration and OSD tree don't change
OSDs often change their /pg/history keys during rebalance, so monitor receives additional
transaction failures from etcd if it re-runs lpsolve which sometimes may even lead to monitor
being unable to apply PG changes at all until rebalance completes

Vitaliy Filippov f72f14e6a7 Clear old PG states, history, and OSD states on etcd state reload
Also add protection from etcd watcher messages being split into multiple websocket
messages - I'm not sure if etcd actually does that, but it's better to have extra
protection anyway.

Also check that all etcd watchers are started in the keepalive routine, otherwise
it sometimes tries to revive etcd watchers starting with revision=1 which obviously
always fails because this revision is nearly always compacted.

All these changes should fix an old rarely reproduced bug where SOMETIMES OSDs
didn't react to PG config changes which was leading to offline pools on node reboot.
It happened on the full reload of state from etcd.

New features:
- RDMA without ODP - much faster and all cards are now supported, not just Mellanox
- VDUSE in CSI - faster, more stable and can even recover after CSI pod restart!
- Reserve journal space for stabilize requests dynamically to prevent stalls under load with EC
- Raise default NBD timeout from 30 to 300 seconds and allow to take it from /etc/vitastor/vitastor.conf
- Remove explicit etcdUrl/etcdPrefix K8S storage class parameter support to prevent
  etcd migration issues for volumes created with these parameters
- Support QEMU 8.1 and pve-qemu 8.1

Bug fixes:
- Fix RDMA connection (and thus memory) leak
- Fix rare crashes under load due to incorrect io_uring queue size tracking
- Fix monitor statistics aggregation in case of empty /osd/stats keys
- Fix crash on unknown long argument to vitastor-disk
- Allow trailing comma in JSONs again
- Fix crash on attempts to dump a long listing of objects "to stabilize" or "to rollback" in a slow op

Vitaliy Filippov 5524dbdab7 Release 1.2.0
New features:

- Implement CSI volume expansion
- Implement CSI volume snapshots
- CSI driver now requires Kubernetes >= 1.20

Bug fixes:

- Important bug fix for EC: fix EC n+k, k>=2 read recovery in ISA-L version returning
  incorrect data when reading at least the second chunk out of multiple missing chunks
  without reading the first one. All users of EC n+k, k>=2 should upgrade as soon as
  possible, and upgrade should be conducted with downtime: first stop all clients
  (VMs/containers), then all OSDs, then upgrade and restart everything.
- Fix unstable statistics aggregation in monitor (affecting vitastor-cli status and df)
- Make udev not wait for OSDs to start during boot
- Do not report negative numbers of offline PGs in vitastor-cli status when changing PG count
- Report both old and new PG counts in vitastor-cli df when changing it
- Fix OSDs sometimes not starting with "The code only supports journal versions 1 and 2,
  but it is 2 on disk" error after upgrading from pre-1.0 versions and letting OSDs run
  for some time
- Fix monitors sometimes returning old PG count back after OSD configuration changes
- Make monitor PG changes more stable and timeout errors less probable

Vitaliy Filippov 8222e3c77d Release 1.1.0
New features:

- Implement [client writeback cache](docs/config/client.en.md#client_enable_writeback)
- Add the third I/O mode: [O_DIRECT|O_SYNC](docs/config/osd.en.md#data_io) (good for Optane)
- Reduce load on etcd by splitting OSD lease and statistics reporting intervals:
  [etcd_stats_interval](docs/config/osd.en.md#etcd_stats_interval) (default 30 sec)
- Make MON automatically filter OSDs by layout (block_size/immediate_commit/bitmap_granularity)
  to prevent "refusing to start PGs of this pool" errors on misconfiguration
- Support running fio benchmarks on systems without io_uring
- Make QEMU driver compatible with QEMU 8.1
- Document usage of [vhost-user-blk](docs/usage/qemu.en.md#vhost-user-blk)

Bug fixes:

- Fix resizing disks in QEMU driver (for example, in Proxmox)
- Fix "unexpected result" in Proxmox driver by making CLI flush output on exit
- Remove unneeded block_size mismatch warnings on pools without matching PGs
- Fix possible segfault in vitastor-cli ls -l (usually with deleted pools)
- Fix QEMU driver compatibility with systems without io_uring
- Fix monitor eating 100% CPU when etcd is down (caused by infinite retries)
- Fix potential incorrect write processing with snapshots (not caught in tests
  but could probably lead to client hangs)
- Fix buffer insertion in cluster_client (not caught in tests but could
  probably lead to incorrect writes in rare cases)
- Fix rare OSD crash during sync operation processing
- Fix a reenterability issue in cluster_client not reproducible in QEMU/fio,
  but reproducible with the currently developed K/V database implementation
- Fix deletion of the first modified object - OSDs could crash if you modified
  the same object a lot of times, then deleted it, and then modified it again
- Fix the fio_sec_osd test tool

# Client Parameters
These parameters apply only to Vitastor clients (QEMU, fio, NBD and so on) and
affect their interaction with the cluster.
- [client_max_dirty_bytes](#client_max_dirty_bytes)
- [client_max_dirty_ops](#client_max_dirty_ops)
- [client_enable_writeback](#client_enable_writeback)
- [client_max_buffered_bytes](#client_max_buffered_bytes)
- [client_max_buffered_ops](#client_max_buffered_ops)
- [client_max_writeback_iodepth](#client_max_writeback_iodepth)
- [nbd_timeout](#nbd_timeout)
- [nbd_max_devices](#nbd_max_devices)
- [nbd_max_part](#nbd_max_part)
## client_max_dirty_bytes
- Type: integer
- Default: 33554432
- Can be changed online: yes
Without [immediate_commit](layout-cluster.en.md#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.
## client_max_dirty_ops
- Type: integer
- Default: 1024
- Can be changed online: yes
Same as client_max_dirty_bytes, but instead of total size, limits the number
of uncommitted write operations.
## client_enable_writeback
- Type: boolean
- Default: false
- Can be changed online: yes
This parameter enables client-side write buffering. This means that write
requests are accumulated in memory for a short time before being sent to
a Vitastor cluster which allows to send them in parallel and increase
performance of some applications. Writes are buffered until client forces
a flush with fsync() or until the amount of buffered writes exceeds the
limit.
Write buffering significantly increases performance of some applications,
for example, CrystalDiskMark under Windows (LOL :-D), but also any other
applications if they do writes in one of two non-optimal ways: either if
they do a lot of small (4 kb or so) sequential writes, or if they do a lot
of small random writes, but without any parallelism or asynchrony, and also
without calling fsync().
With write buffering enabled, you can expect around 22000 T1Q1 random write
iops in QEMU more or less regardless of the quality of your SSDs, and this
number is in fact bound by QEMU itself rather than Vitastor (check it
yourself by adding a "driver=null-co" disk in QEMU). Without write
buffering, the current record is 9900 iops, but the number is usually
even lower with non-ideal hardware, for example, it may be 5000 iops.
Even when this parameter is enabled, write buffering isn't enabled until
the client explicitly allows it, because enabling it without the client
being aware of the fact that his writes may be buffered may lead to data
loss. Because of this, older versions of clients don't support write
buffering at all, newer versions of the QEMU driver allow write buffering
only if it's enabled in disk settings with `-blockdev cache.direct=false`,
and newer versions of FIO only allow write buffering if you don't specify
`-direct=1`. NBD and NFS drivers allow write buffering by default.
You can overcome this restriction too with the `client_writeback_allowed`
parameter, but you shouldn't do that unless you **really** know what you
are doing.
## client_max_buffered_bytes
- Type: integer
- Default: 33554432
- Can be changed online: yes
Maximum total size of buffered writes which triggers write-back when reached.
## client_max_buffered_ops
- Type: integer
- Default: 1024
- Can be changed online: yes
Maximum number of buffered writes which triggers write-back when reached.
Multiple consecutive modified data regions are counted as 1 write here.
## client_max_writeback_iodepth
- Type: integer
- Default: 256
- Can be changed online: yes
Maximum number of parallel writes when flushing buffered data to the server.
## nbd_timeout
- Type: seconds
- Default: 300
Timeout for I/O operations for [NBD](../usage/nbd.en.md). If an operation
executes for longer than this timeout, including when your cluster is just
temporarily down for more than timeout, the NBD device will detach by itself
(and possibly break the mounted file system).
You can set timeout to 0 to never detach, but in that case you won't be
able to remove the kernel device at all if the NBD process dies - you'll have
to reboot the host.
## nbd_max_devices
- Type: integer
- Default: 64
Maximum number of NBD devices in the system. This value is passed as
`nbds_max` parameter for the nbd kernel module when vitastor-nbd autoloads it.
## nbd_max_part
- Type: integer
- Default: 3
Maximum number of partitions per NBD device. This value is passed as
`max_part` parameter for the nbd kernel module when vitastor-nbd autoloads it.
Note that (nbds_max)*(1+max_part) usually can't exceed 256.

## client_max_dirty_bytes
- Тип: целое число
- Значение по умолчанию: 33554432
- Можно менять на лету: да
При работе без [immediate_commit](layout-cluster.ru.md#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.
## client_max_dirty_ops
- Тип: целое число
- Значение по умолчанию: 1024
- Можно менять на лету: да
Аналогично client_max_dirty_bytes, но ограничивает количество
незафиксированных операций записи вместо их общего объёма.
## client_enable_writeback
- Тип: булево (да/нет)
- Значение по умолчанию: false
- Можно менять на лету: да
Данный параметр разрешает включать буферизацию записи в памяти. Буферизация
означает, что операции записи отправляются на кластер Vitastor не сразу, а
могут небольшое время накапливаться в памяти и сбрасываться сразу пакетами,
до тех пор, пока либо не будет превышен лимит неотправленных записей, либо
пока клиент не вызовет fsync.
Буферизация значительно повышает производительность некоторых приложений,
например, CrystalDiskMark в Windows (ха-ха :-D), но также и любых других,
которые пишут на диск неоптимально: либо последовательно, но мелкими блоками
(например, по 4 кб), либо случайно, но без параллелизма и без fsync - то
есть, например, отправляя 128 операций записи в разные места диска, но не
все сразу с помощью асинхронного I/O, а по одной.
В QEMU с буферизацией записи можно ожидать показателя примерно 22000
операций случайной записи в секунду в 1 поток и с глубиной очереди 1 (T1Q1)
без fsync, почти вне зависимости от того, насколько хороши ваши диски - эта
цифра упирается в сам QEMU. Без буферизации рекорд пока что - 9900 операций
в секунду, но на железе похуже может быть и поменьше, например, 5000 операций
в секунду.
При этом, даже если данный параметр включён, буферизация не включается, если
явно не разрешена клиентом, т.к. если клиент не знает, что запросы записи
буферизуются, это может приводить к потере данных. Поэтому в старых версиях
клиентских драйверов буферизация записи не включается вообще, в новых
версиях QEMU-драйвера включается, только если разрешена опцией диска
`-blockdev cache.direct=false`, а в fio - только если нет опции `-direct=1`.
В NBD и NFS драйверах буферизация записи разрешена по умолчанию.
Можно обойти и это ограничение с помощью параметра `client_writeback_allowed`,
но делать так не надо, если только вы не уверены в том, что делаете, на все
100%. :-)
## client_max_buffered_bytes
- Тип: целое число
- Значение по умолчанию: 33554432
- Можно менять на лету: да
Максимальный общий размер буферизованных записей, при достижении которого
начинается процесс сброса данных на сервер.
## client_max_buffered_ops
- Тип: целое число
- Значение по умолчанию: 1024
- Можно менять на лету: да
Максимальное количество буферизованных записей, при достижении которого
начинается процесс сброса данных на сервер. При этом несколько
последовательных изменённых областей здесь считаются 1 записью.
## client_max_writeback_iodepth
- Тип: целое число
- Значение по умолчанию: 256
- Можно менять на лету: да
Максимальное число параллельных операций записи при сбросе буферов на сервер.
## nbd_timeout
- Тип: секунды
- Значение по умолчанию: 300
Таймаут для операций чтения/записи через [NBD](../usage/nbd.ru.md). Если
операция выполняется дольше таймаута, включая временную недоступность
кластера на время, большее таймаута, NBD-устройство отключится само собой
(и, возможно, сломает примонтированную ФС).
Вы можете установить таймаут в 0, чтобы никогда не отключать устройство по
таймауту, но в этом случае вы вообще не сможете удалить устройство, если
процесс NBD умрёт - вам придётся перезагружать сервер.
## nbd_max_devices
- Тип: целое число
- Значение по умолчанию: 64
Максимальное число NBD-устройств в системе. Данное значение передаётся
модулю ядра nbd как параметр `nbds_max`, когда его загружает vitastor-nbd.
## nbd_max_part
- Тип: целое число
- Значение по умолчанию: 3
Максимальное число разделов на одном NBD-устройстве. Данное значение передаётся
модулю ядра nbd как параметр `max_part`, когда его загружает vitastor-nbd.
Имейте в виду, что (nbds_max)*(1+max_part) обычно не может превышать 256.

## rdma_odp
- Type: boolean
- Default: false
Use RDMA with On-Demand Paging. ODP is currently only available on Mellanox
ConnectX-4 and newer adapters. ODP allows to not register memory explicitly
for RDMA adapter to be able to use it. This, in turn, allows to skip memory
copying during sending. One would think this should improve performance, but
**in reality** RDMA performance with ODP is **drastically** worse. Example
3-node cluster with 8 NVMe in each node and 2*25 GBit/s ConnectX-6 RDMA network
without ODP pushes 3950000 read iops, but only 239000 iops with ODP...
This happens because Mellanox ODP implementation seems to be based on
message retransmissions when the adapter doesn't know about the buffer yet -
it likely uses standard "RNR retransmissions" (RNR = receiver not ready)
which is generally slow in RDMA/RoCE networks. Here's a presentation about
it from ISPASS-2021 conference: https://tkygtr6.github.io/pub/ISPASS21_slides.pdf
ODP support is retained in the code just in case a good ODP implementation

Использовать RDMA с On-Demand Paging. ODP - функция, доступная пока что
исключительно на адаптерах Mellanox ConnectX-4 и более новых. ODP позволяет
не регистрировать память для её использования RDMA-картой. Благодаря этому
можно не копировать данные при отправке их в сеть и, казалось бы, это должно
улучшать производительность - но **по факту** получается так, что
производительность только ухудшается, причём сильно. Пример - на 3-узловом
кластере с 8 NVMe в каждом узле и сетью 2*25 Гбит/с на чтение с RDMA без ODP
удаётся снять 3950000 iops, а с ODP - всего 239000 iops...
Это происходит из-за того, что реализация ODP у Mellanox неоптимальная и
основана на повторной передаче сообщений, когда карте не известен буфер -
вероятно, на стандартных "RNR retransmission" (RNR = receiver not ready).
А данные повторные передачи в RDMA/RoCE - всегда очень медленная штука.

Auto-tuning targets utilization. Utilization is a measure of load and is
equal to the product of iops and average latency (so it may be greater
than 1). You set "low" and "high" client utilization thresholds and two
corresponding target recovery utilization levels. OSD calculates desired
recovery utilization from client utilization using linear interpolation
and auto-tunes recovery operation delay to make actual recovery utilization
match desired.
This allows to reduce recovery/rebalance impact on client operations. It is
of course impossible to remove it completely, but it should become adequate.

Автотюнинг (автоподстройка) отключается, если recovery_tune_interval
устанавливается в значение 0.
Автотюнинг регулирует утилизацию. Утилизация является мерой нагрузки
и равна произведению числа операций в секунду и средней задержки
(то есть, она может быть выше 1). Вы задаёте два уровня клиентской
утилизации - "низкий" и "высокий" (low и high) и два соответствующих

желаемый уровень утилизации восстановления линейной интерполяцией от
клиентской утилизации и подстраивает задержку операций восстановления
так, чтобы фактическая утилизация восстановления совпадала с желаемой.
Это позволяет снизить влияние восстановления и ребаланса на клиентские
операции. Конечно, невозможно исключить такое влияние полностью, но оно
должно становиться адекватнее. В некоторых тестах перебалансировка могла

info: |
This parameter enables client-side write buffering. This means that write
requests are accumulated in memory for a short time before being sent to
a Vitastor cluster which allows to send them in parallel and increase
performance of some applications. Writes are buffered until client forces
a flush with fsync() or until the amount of buffered writes exceeds the
limit.
Write buffering significantly increases performance of some applications,
for example, CrystalDiskMark under Windows (LOL :-D), but also any other
applications if they do writes in one of two non-optimal ways: either if
they do a lot of small (4 kb or so) sequential writes, or if they do a lot
of small random writes, but without any parallelism or asynchrony, and also
without calling fsync().
With write buffering enabled, you can expect around 22000 T1Q1 random write
iops in QEMU more or less regardless of the quality of your SSDs, and this
number is in fact bound by QEMU itself rather than Vitastor (check it
yourself by adding a "driver=null-co" disk in QEMU). Without write
buffering, the current record is 9900 iops, but the number is usually
even lower with non-ideal hardware, for example, it may be 5000 iops.
Even when this parameter is enabled, write buffering isn't enabled until
the client explicitly allows it, because enabling it without the client
being aware of the fact that his writes may be buffered may lead to data
loss. Because of this, older versions of clients don't support write
buffering at all, newer versions of the QEMU driver allow write buffering
only if it's enabled in disk settings with `-blockdev cache.direct=false`,
and newer versions of FIO only allow write buffering if you don't specify
`-direct=1`. NBD and NFS drivers allow write buffering by default.
You can overcome this restriction too with the `client_writeback_allowed`
parameter, but you shouldn't do that unless you **really** know what you
are doing.
info_ru: |
Данный параметр разрешает включать буферизацию записи в памяти. Буферизация
означает, что операции записи отправляются на кластер Vitastor не сразу, а
могут небольшое время накапливаться в памяти и сбрасываться сразу пакетами,
до тех пор, пока либо не будет превышен лимит неотправленных записей, либо
пока клиент не вызовет fsync.
Буферизация значительно повышает производительность некоторых приложений,
например, CrystalDiskMark в Windows (ха-ха :-D), но также и любых других,
которые пишут на диск неоптимально: либо последовательно, но мелкими блоками
(например, по 4 кб), либо случайно, но без параллелизма и без fsync - то
есть, например, отправляя 128 операций записи в разные места диска, но не
все сразу с помощью асинхронного I/O, а по одной.
В QEMU с буферизацией записи можно ожидать показателя примерно 22000
операций случайной записи в секунду в 1 поток и с глубиной очереди 1 (T1Q1)
без fsync, почти вне зависимости от того, насколько хороши ваши диски - эта
цифра упирается в сам QEMU. Без буферизации рекорд пока что - 9900 операций
в секунду, но на железе похуже может быть и поменьше, например, 5000 операций
в секунду.
При этом, даже если данный параметр включён, буферизация не включается, если
явно не разрешена клиентом, т.к. если клиент не знает, что запросы записи
буферизуются, это может приводить к потере данных. Поэтому в старых версиях
клиентских драйверов буферизация записи не включается вообще, в новых
версиях QEMU-драйвера включается, только если разрешена опцией диска
`-blockdev cache.direct=false`, а в fio - только если нет опции `-direct=1`.
В NBD и NFS драйверах буферизация записи разрешена по умолчанию.
Можно обойти и это ограничение с помощью параметра `client_writeback_allowed`,
но делать так не надо, если только вы не уверены в том, что делаете, на все
100%. :-)

Use RDMA with On-Demand Paging. ODP is currently only available on Mellanox
ConnectX-4 and newer adapters. ODP allows to not register memory explicitly
for RDMA adapter to be able to use it. This, in turn, allows to skip memory
copying during sending. One would think this should improve performance, but
**in reality** RDMA performance with ODP is **drastically** worse. Example
3-node cluster with 8 NVMe in each node and 2*25 GBit/s ConnectX-6 RDMA network
without ODP pushes 3950000 read iops, but only 239000 iops with ODP...
This happens because Mellanox ODP implementation seems to be based on
message retransmissions when the adapter doesn't know about the buffer yet -
it likely uses standard "RNR retransmissions" (RNR = receiver not ready)
which is generally slow in RDMA/RoCE networks. Here's a presentation about
it from ISPASS-2021 conference: https://tkygtr6.github.io/pub/ISPASS21_slides.pdf
ODP support is retained in the code just in case a good ODP implementation
appears one day.
info_ru: |
Использовать RDMA с On-Demand Paging. ODP - функция, доступная пока что
исключительно на адаптерах Mellanox ConnectX-4 и более новых. ODP позволяет
не регистрировать память для её использования RDMA-картой. Благодаря этому
можно не копировать данные при отправке их в сеть и, казалось бы, это должно
улучшать производительность - но **по факту** получается так, что
производительность только ухудшается, причём сильно. Пример - на 3-узловом
кластере с 8 NVMe в каждом узле и сетью 2*25 Гбит/с на чтение с RDMA без ODP
удаётся снять 3950000 iops, а с ODP - всего 239000 iops...
Это происходит из-за того, что реализация ODP у Mellanox неоптимальная и
основана на повторной передаче сообщений, когда карте не известен буфер -
вероятно, на стандартных "RNR retransmission" (RNR = receiver not ready).
А данные повторные передачи в RDMA/RoCE - всегда очень медленная штука.
Презентация на эту тему с конференции ISPASS-2021: https://tkygtr6.github.io/pub/ISPASS21_slides.pdf
Возможность использования ODP сохранена в коде на случай, если вдруг в один

corresponding target recovery utilization levels. OSD calculates desired
recovery utilization from client utilization using linear interpolation
and auto-tunes recovery operation delay to make actual recovery utilization
match desired.
This allows to reduce recovery/rebalance impact on client operations. It is

After that you'll be able to create PersistentVolumes.
**Important:** For best experience, use Linux kernel at least 5.15 with [VDUSE](../usage/qemu.en.md#vduse)
kernel modules enabled (vdpa, vduse, virtio-vdpa). If your distribution doesn't
have them pre-built - build them yourself ([instructions](../usage/qemu.en.md#vduse)),
I promise it's worth it :-). When VDUSE is unavailable, CSI driver uses [NBD](../usage/nbd.en.md)
to map Vitastor devices. NBD is slower and prone to timeout issues: if Vitastor
cluster becomes unresponsible for more than [nbd_timeout](../config/client.en.md#nbd_timeout),
the NBD device detaches and breaks pods using it.
## Features
Vitastor CSI supports:
- Kubernetes starting with 1.20 (or 1.17 for older vitastor-csi <= 1.1.0)
- Filesystem RWO (ReadWriteOnce) volumes. Example: [PVC](../../csi/deploy/example-pvc.yaml), [pod](../../csi/deploy/example-test-pod.yaml)
- Raw block RWX (ReadWriteMany) volumes. Example: [PVC](../../csi/deploy/example-pvc-block.yaml), [pod](../../csi/deploy/example-test-pod-block.yaml)
- Volume expansion
- Volume snapshots. Example: [snapshot class](../../csi/deploy/example-snapshot-class.yaml), [snapshot](../../csi/deploy/example-snapshot.yaml), [clone](../../csi/deploy/example-snapshot-clone.yaml)
- [VDUSE](../usage/qemu.en.md#vduse) (preferred) and [NBD](../usage/nbd.en.md) device mapping methods
- Upgrades with VDUSE - new handler processes are restarted when CSI pods are restarted themselves
- VDUSE daemon auto-restart - handler processes are automatically restarted if they crash due to a bug in Vitastor client code
- Multiple clusters by using multiple configuration files in ConfigMap.
Remember that to use snapshots with CSI you also have to install [Snapshot Controller and CRDs](https://kubernetes-csi.github.io/docs/snapshot-controller.html#deployment).

После этого вы сможете создавать PersistentVolume.
**Важно:** Лучше всего использовать ядро Linux версии не менее 5.15 с включёнными модулями
[VDUSE](../usage/qemu.ru.md#vduse) (vdpa, vduse, virtio-vdpa). Если в вашем дистрибутиве
они не собраны из коробки - соберите их сами, обещаю, что это стоит того ([инструкция](../usage/qemu.ru.md#vduse)) :-).
Когда VDUSE недоступно, CSI-плагин использует [NBD](../usage/nbd.ru.md) для подключения
дисков, а NBD медленнее и имеет проблему таймаута - если кластер остаётся недоступным
дольше, чем [nbd_timeout](../config/client.ru.md#nbd_timeout), NBD-устройство отключается
и ломает поды, использующие его.
## Возможности
CSI-плагин Vitastor поддерживает:
- Версии Kubernetes, начиная с 1.20 (или с 1.17 для более старых vitastor-csi <= 1.1.0)
- Файловые RWO (ReadWriteOnce) тома. Пример: [PVC](../../csi/deploy/example-pvc.yaml), [под](../../csi/deploy/example-test-pod.yaml)
- Сырые блочные RWX (ReadWriteMany) тома. Пример: [PVC](../../csi/deploy/example-pvc-block.yaml), [под](../../csi/deploy/example-test-pod-block.yaml)
- Расширение размера томов
- Снимки томов. Пример: [класс снимков](../../csi/deploy/example-snapshot-class.yaml), [снимок](../../csi/deploy/example-snapshot.yaml), [клон снимка](../../csi/deploy/example-snapshot-clone.yaml)
- Способы подключения устройств [VDUSE](../usage/qemu.ru.md#vduse) (предпочитаемый) и [NBD](../usage/nbd.ru.md)
- Обновление при использовании VDUSE - новые процессы-обработчики устройств успешно перезапускаются вместе с самими подами CSI
- Автоперезауск демонов VDUSE - процесс-обработчик автоматически перезапустится, если он внезапно упадёт из-за бага в коде клиента Vitastor
- Несколько кластеров через задание нескольких файлов конфигурации в ConfigMap.
Не забывайте, что для использования снимков нужно сначала установить [контроллер снимков и CRD](https://kubernetes-csi.github.io/docs/snapshot-controller.html#deployment).

## vhost-user-blk
QEMU, starting with 6.0, includes support for attaching disks via a separate
userspace worker process, called `vhost-user-blk`. It usually has slightly (20-30 us)
lower latency.
Example commands to use it with Vitastor:
```
qemu-storage-daemon \
--daemonize \
--blockdev '{"node-name":"drive-virtio-disk1","driver":"vitastor","image":"testosd1","cache":{"direct":true,"no-flush":false},"auto-read-only":true,"discard":"unmap"}' \
--export type=vhost-user-blk,id=vitastor1,node-name=drive-virtio-disk1,addr.type=unix,addr.path=/run/vitastor1-user-blk.sock,writable=on,num-queues=1

memfd memory-backend is crucial, vhost-user-blk does not work without it.
## VDUSE
Linux kernel, starting with version 5.15, supports a new interface for attaching virtual disks
to the host - VDUSE (vDPA Device in Userspace). QEMU, starting with 7.2, has support for
exporting QEMU block devices over this protocol using qemu-storage-daemon.
VDUSE has the same problem as other FUSE-like interfaces in Linux: if a userspace process hangs,
for example, if it loses connectivity with Vitastor cluster - active processes doing I/O may
hang in the D state (uninterruptible sleep) and you won't be able to kill them even with kill -9.
In this case reboot will be the only way to remove VDUSE devices from system.
VDUSE is currently the best interface to attach Vitastor disks as kernel devices because:
- It avoids data copies and thus achieves much better performance than [NBD](nbd.en.md)
- It doesn't have NBD timeout problem - the device doesn't die if an operation executes for too long
- It doesn't have hung device problem - if the userspace process dies it can be restarted (!)
and block device will continue operation
- It doesn't seem to have the device number limit
On the other hand, VDUSE is faster than [NBD](nbd.en.md), so you may prefer to use it if
performance is important for you. Approximate performance numbers:
direct fio benchmark - 115000 iops, NBD - 60000 iops, VDUSE - 90000 iops.
Example performance comparison:
| | direct fio | NBD | VDUSE |
|----------------------|-------------|-------------|-------------|
| linear write | 3.85 GB/s | 1.12 GB/s | 3.85 GB/s |
| 4k random write Q128 | 240000 iops | 120000 iops | 178000 iops |
| 4k random write Q1 | 9500 iops | 7620 iops | 7640 iops |
| linear read | 4.3 GB/s | 1.8 GB/s | 2.85 GB/s |
| 4k random read Q128 | 287000 iops | 140000 iops | 189000 iops |
| 4k random read Q1 | 9600 iops | 7640 iops | 7780 iops |
To try VDUSE you need at least Linux 5.15, built with VDUSE support
(CONFIG_VIRTIO_VDPA=m and CONFIG_VDPA_USER=m). Debian Linux kernels have these options
disabled by now, so if you want to try it on Debian, use a kernel from Ubuntu

## vhost-user-blk

Пример команд для использования vhost-user-blk с Vitastor:
```

--blockdev '{"node-name":"drive-virtio-disk1","driver":"vitastor","image":"testosd1","cache":{"direct":true,"no-flush":false},"auto-read-only":true,"discard":"unmap"}' \

## VDUSE
В Linux, начиная с версии ядра 5.15, доступен новый интерфейс для подключения виртуальных дисков
к системе - VDUSE (vDPA Device in Userspace), а в QEMU, начиная с версии 7.2, есть поддержка
экспорта блочных устройств QEMU по этому протоколу через qemu-storage-daemon.
VDUSE страдает общей проблемой FUSE-подобных интерфейсов в Linux: если пользовательский процесс
подвиснет, например, если будет потеряна связь с кластером Vitastor - читающие/пишущие в кластер
процессы могут "залипнуть" в состоянии D (непрерываемый сон) и их будет невозможно убить даже
через kill -9. В этом случае удалить из системы устройство можно только перезагрузившись.
VDUSE - на данный момент лучший интерфейс для подключения дисков Vitastor в виде блочных
устройств на уровне ядра, ибо:
- VDUSE не копирует данные и поэтому достигает значительно лучшей производительности, чем [NBD](nbd.ru.md)
- Также оно не имеет проблемы NBD-таймаута - устройство не умирает, если операция выполняется слишком долго
- Также оно не имеет проблемы подвисающих устройств - если процесс-обработчик умирает, его можно
перезапустить (!) и блочное устройство продолжит работать
- По-видимому, у него нет предела числа подключаемых в систему устройств
С другой стороны, VDUSE быстрее по сравнению с [NBD](nbd.ru.md), поэтому его может
быть предпочтительно использовать там, где производительность важнее. Порядок показателей:
прямое тестирование через fio - 115000 iops, NBD - 60000 iops, VDUSE - 90000 iops.
Пример сравнения производительности:
Чтобы использовать VDUSE, вам нужно ядро Linux версии хотя бы 5.15, собранное с поддержкой
VDUSE (CONFIG_VIRTIO_VDPA=m и CONFIG_VDPA_USER=m). В ядрах в Debian Linux поддержка пока
отключена - если хотите попробовать эту функцию на Debian, поставьте ядро из Ubuntu
[kernel-ppa/mainline](https://kernel.ubuntu.com/~kernel-ppa/mainline/) или из Proxmox.

| 4k случайная запись Q128 | 240000 iops | 120000 iops | 178000 iops |
| 4k случайная запись Q1 | 9500 iops | 7620 iops | 7640 iops |

| 4k случайное чтение Q1 | 9600 iops | 7640 iops | 7780 iops |
Чтобы попробовать VDUSE, вам нужно ядро Linux как минимум версии 5.15, собранное с поддержкой
VDUSE (CONFIG_VDPA=m, CONFIG_VDPA_USER=m, CONFIG_VIRTIO_VDPA=m).
В ядрах в Debian Linux поддержка пока отключена по умолчанию, так что чтобы попробовать VDUSE
на Debian, поставьте ядро из Ubuntu [kernel-ppa/mainline](https://kernel.ubuntu.com/~kernel-ppa/mainline/),
из Proxmox или соберите модули для ядра Debian вручную:
```
mkdir build
cd build
