with replicated pools and reach the best possible write performance.
|

|
||||
Default value is auto-detected during OSD initialization from
|
||||
`/sys/block/xx/queue/atomic_write_max_bytes` or assumed to be 4096 bytes
|
||||
because all known disks support 4 KB atomic writes. Auto-detection is only used for
|
||||
NVMe disks because SAS disks require the explicit WRITE ATOMIC command which requires
|
||||
RWF_ATOMIC (see below [#use_atomic_flag]) but that flag works incorrectly in current
|
||||
Linux versions.
|
||||
|
||||
You can also check if your NVMe drives support atomic writes by running
|
||||
the command `nvme id-ctrl /dev/nvme0n1 | grep awupf`. If the reported value,
|
||||
plus 1, multiplied by the currently selected block size of the NVMe,
|
||||
is more than 4 KB, then the new store can utilize it for better performance.
|
||||
The only drives known to support it currently are [Micron and Kioxia](../intro/quickstart.en.md).

## use_atomic_flag

- Type: boolean
|

|

This option controls whether Vitastor OSDs use RWF_ATOMIC write flag with atomic writes.
|
||||
This flag is supported since Linux 6.11 and adds some safety to atomic writes - the kernel
|
||||
guarantees to not fragment write requests with it and also to check them against the actual
|
||||
device atomic write capabilities.
|
||||
|
||||
However, the option is disabled by default because the flag is currently UNUSABLE - Linux
|
||||
incorrectly requires writes with that flag to be of power-of-2 length and length-aligned.
|
||||
I.e., for example, 12 KB writes and not-8-KB aligned 8 KB writes are forbidden by the kernel,
|
||||
even though the NVMe specification allows them.
|
||||
|
||||
For NVMe disks with `scheduler=none` writes aren't fragmented anyway so it's not a big deal.
|
||||
However, you can rebuild your kernel with [this patch](../../patches/linux-fix-atomic-write-checks.diff)
|
||||
and turn this option on. It will make your atomic writes a bit safer.

Pool PG count change is a CPU-intensive operation because OSDs store the full object database
|
||||
in memory and have to move all entries between old and new PGs. Thus it's performed in chunks,

||||

Значение по умолчанию авто-определяется во время инициализации OSD из
|
||||
`/sys/block/xx/queue/atomic_write_max_bytes` либо принимается равным 4096,
|
||||
так как все известные диски поддерживают атомарную запись 4 КБ блоков.
|
||||
Автоопределение применяется только для NVMe-дисков, так как SAS диски требуют
|
||||
использования отдельной команды WRITE ATOMIC, а для неё нужен флаг RWF_ATOMIC
|
||||
(см. ниже [#use_atomic_flag]), а он в текущих версиях Linux работает некорректно.
|
||||
|
||||
Вы также можете проверить, поддерживают ли ваши NVMe-диски атомарную запись,
|
||||
с помощью команды `nvme id-ctrl /dev/nvme0n1 | grep awupf`. Если значение awupf
|
||||
плюс 1, умноженное на текущий выбранный размер блока NVMe-диска, больше 4 КБ,
|
||||
то новое хранилище может использовать атомарные записи для достижения лучшей
|

производительности. Единственные известные диски, которые поддерживают это сейчас -
|
||||
[Micron и Kioxia](../intro/quickstart.ru.md).
|
||||
|
||||
Атомарная запись позволяет не использовать двойную запись данных (в журнал и на
|
||||
устройство данных) в реплицированных пулах и таким образом снижает амплификацию
|
||||
записи (объём служебной записи на диск) и улучшает производительность записи

вплоть до 2-х кратного прироста.

Данная опция контролирует использование Vitastor OSD флага RWF_ATOMIC при атомарной записи
|
||||
блоков. Этот флаг поддерживается, начиная с версии ядра Linux 6.11 и добавляет немного корректности
|
||||
атомарным записям - ядро гарантирует отсутствие фрагментации запросов записи с этим флагом и
|
||||
проверяет их на соответствие реальным возможностям устройства.
|
||||
|
||||
Однако, данная опция по умолчанию отключена, так как флаг в текущих версиях Linux работает
|
||||
абсолютно НЕКОРРЕКТНО - при нём Linux требует, чтобы запросы записи имели длину, равную
|
||||
степени двойки и были выровнены на эту длину. То есть, например, 12 КБ запросы записи, а также
|
||||
8 КБ запросы записи по не-кратному 8 КБ смещению запрещаются ядром, хотя спецификация NVMe их
|
||||
разрешает.
|
||||
|
||||
Для NVMe-дисков с `scheduler=none` запросы записи и так не фрагментируются, так что это не так
|
||||
уж и важно, однако вы можете пересобрать своё ядро с [этим патчем](../../patches/linux-fix-atomic-write-checks.diff)

- Тип: целое число

|

|

Изменение числа PG в пуле заметно загружает процессор, так как OSD хранят полную базу данных
|
||||
объектов в памяти и им приходится перемещать все записи объектов между старыми и новыми PG.
|
||||
Поэтому изменение применяется порциями, с паузами между порциями, чтобы не блокировать обработку
|
||||
событий OSD и операции остальных клиентов. Данная опция задаёт максимальное число объектов
|
||||
в порции. Перемещение 100 тысяч объектов (значение по умолчанию) обычно занимает порядка
|

50-100 миллисекунд. Значение опции 0 отключает лимит размера порции.

Encryption keys may be stored in etcd or, for the increased security level, in an external
|
||||
[HashiCorp Vault](https://developer.hashicorp.com/vault/) or [OpenBao](https://openbao.org/)
|
||||

Default value is auto-detected during OSD initialization from

because all known disks support 4 KB atomic writes. Auto-detection is only used for

NVMe disks because SAS disks require the explicit WRITE ATOMIC command which requires
|

RWF_ATOMIC (see below [#use_atomic_flag]) but that flag works incorrectly in current

Linux versions.
|

|

You can also check if your NVMe drives support atomic writes by running

the command `nvme id-ctrl /dev/nvme0n1 | grep awupf`. If the reported value,

plus 1, multiplied by the currently selected block size of the NVMe,

так как все известные диски поддерживают атомарную запись 4 КБ блоков.

Автоопределение применяется только для NVMe-дисков, так как SAS диски требуют
|

использования отдельной команды WRITE ATOMIC, а для неё нужен флаг RWF_ATOMIC
|
||||
(см. ниже [#use_atomic_flag]), а он в текущих версиях Linux работает некорректно.
|
||||
|
||||
Вы также можете проверить, поддерживают ли ваши NVMe-диски атомарную запись,

с помощью команды `nvme id-ctrl /dev/nvme0n1 | grep awupf`. Если значение awupf
|

This option controls whether Vitastor OSDs use RWF_ATOMIC write flag with atomic writes.

device atomic write capabilities.
|
||||
|
||||
However, the option is disabled by default because the flag is currently UNUSABLE - Linux
|
||||
incorrectly requires writes with that flag to be of power-of-2 length and length-aligned.
|
||||
I.e., for example, 12 KB writes and not-8-KB aligned 8 KB writes are forbidden by the kernel,
|
||||
even though the NVMe specification allows them.
|
||||
|
||||
For NVMe disks with `scheduler=none` writes aren't fragmented anyway so it's not a big deal.
|

However, you can rebuild your kernel with [this patch](../../patches/linux-fix-atomic-write-checks.diff)

атомарным записям - ядро гарантирует отсутствие фрагментации запросов записи с этим флагом и
|
||||
проверяет их на соответствие реальным возможностям устройства.
|
||||
|
||||
Однако, данная опция по умолчанию отключена, так как флаг в текущих версиях Linux работает

абсолютно НЕКОРРЕКТНО - при нём Linux требует, чтобы запросы записи имели длину, равную

8 КБ запросы записи по не-кратному 8 КБ смещению запрещаются ядром, хотя спецификация NVMe их

разрешает.

Для NVMe-дисков с `scheduler=none` запросы записи и так не фрагментируются, так что это не так

Write amplification for 4 KB blocks is usually 3-5 in Vitastor:
|
||||
1. Journal block write
|
||||
2. Journal data write
|
||||
3. Metadata block write
|
||||
4. Another journal block write for EC/XOR setups
|
||||
5. Data block write
|
||||
Write Amplification factor:
|
||||
- For the new store and for 4 KB writes: WA is always 1 unless you set [atomic_write_size](../config/osd.en.md#atomic_write_size) to 0 manually.
|
||||
- For the new store and for 8-124 KB writes: WA is 1 if you use NVMe drives with atomic write support, or roughly 2 if you use other drives.
|
||||
- For the old store, WA is roughly `(2 * write size + 4 KB) / (write size)`. So, for 4 KB writes it's 3, and for 8-124 KB writes it's closer to 2.
|
||||
- For both the new and the old store and for writes of [block_size](../config/layout-cluster.en.md#block_size): WA is almost 1.
|
||||
|
||||
If you manage to get an SSD which handles 512 byte blocks well (Optane?) you may
|
||||
lower 1, 3 and 4 to 512 bytes (1/8 of data size) and get WA as low as 2.375.
|
||||
Write Amplification consists of:
|
||||
- For the new store:
|
||||
- Buffer block write if non-atomic
|
||||
- Data block write
|
||||
- Metadata write(s) (amortized)
|
||||
- For the old store:
|
||||
- Journal block write (amortized)
|
||||
- Journal data write
|
||||
- Metadata block write
|
||||
- Another journal block write for EC/XOR setups (amortized)
|
||||
- Data block write
|
||||
|
||||
Implemented NVDIMM support can basically eliminate WA at all - all extra writes will
|
||||
go to DRAM memory. But this requires a test cluster with NVDIMM - please contact me
|
||||
if you want to provide me with such cluster for tests.
|
||||
|
||||
Lazy fsync also reduces WA for parallel workloads because journal blocks are only
|
||||
written when they fill up or fsync is requested.
|
||||
Other possibilities to reduce WA would be to use SSDs with internal 512-byte blocks
|
||||
or NVDIMM, but both options seem unavailable on the market at the moment.

WA (мультипликатор записи) для 4 КБ блоков в Vitastor обычно составляет 3-5:
|
||||
1. Запись метаданных в журнал
|
||||
2. Запись блока данных в журнал
|
||||
3. Запись метаданных в БД
|
||||
4. Ещё одна запись метаданных в журнал при использовании EC
|
||||
5. Запись блока данных на диск данных
|
||||
WA (Write Amplification, мультипликатор записи):
|
||||
- С новым хранилищем для 4 КБ записи: WA всегда примерно 1, если только вы не установите [atomic_write_size](../config/osd.ru.md#atomic_write_size) вручную в 0.
|
||||
- С новым хранилищем и большими записями (8-124 КБ): WA примерно 1, если вы используете NVMe-диски с поддержкой атомарной записи,
|
||||
или примерно 2, если вы используете другие диски.
|
||||
- Со старым хранилищем, WA примерно `(2 * размер записи + 4 КБ) / (размер записи)`. То есть, для 4 КБ записи WA=3, а для 8-124 КБ WA ближе к 2.
|
||||
- И с новым, и со старым хранилищем и для записи размером [block_size](../config/layout-cluster.ru.md#block_size): WA примерно равен 1.
|
||||
|
||||
Если вы найдёте SSD, хорошо работающий с 512-байтными блоками данных (Optane?),
|
||||
то 1, 3 и 4 можно снизить до 512 байт (1/8 от размера данных) и получить WA всего 2.375.
|
||||
Мультипликатор записи состоит из:
|
||||
- С новым хранилищем:
|
||||
- Запись блока буфера, если диски без поддержки атомарной записи
|
||||
- Запись блока данных
|
||||
- Запись(-и) блоков метаданных (амортизированные)
|
||||
- Со старым хранилищем:
|
||||
- Запись блока журнала (амортизированная)
|
||||
- Запись данных в журнал
|
||||
- Запись блока метаданных
|
||||
- Ещё одна запись блока журнала для EC/XOR пулов (амортизированная)
|
||||
- Запись блока данных
|
||||
|
||||
Если реализовать поддержку NVDIMM, то WA можно, условно говоря, ликвидировать вообще - все
|
||||
дополнительные операции записи смогут обслуживаться DRAM памятью. Но для этого необходим
|
||||
тестовый кластер с NVDIMM - пишите, если готовы предоставить такой для тестов.
|
||||
|
||||
Кроме того, WA снижается при использовании отложенного/ленивого сброса при параллельной
|
||||
нагрузке, т.к. блоки журнала записываются на диск только когда они заполняются или явным
|
||||
образом запрашивается fsync.
|
||||
Другими потенциальными возможностями снижения WA могли бы быть SSD с внутренним 512-байтным блоком
|
||||
либо NVDIMM, но и то, и другое сейчас выглядит недоступным на рынке.

Subject: [PATCH] Do not require atomic writes to be power of 2 sized and
|
||||
aligned on length boundary
|
||||
|
||||
It contradicts NVMe specification where alignment is only required when atomic
|
||||
write boundary (NABSPF/NABO) is set and highly limits usage of NVMe atomic writes

Vitastor is a small, simple and fast clustered block storage (storage for VM drives),
|
||||
architecturally similar to Ceph which means strong consistency, primary-replication,
|
||||
symmetric clustering and automatic data distribution over any number of drives of any
|
||||
size with configurable redundancy (replication or erasure codes/XOR).
