-Vitastor старается определить повреждённые части объектов при использовании
-EC (кодов коррекции ошибок) с более, чем 1 диском чётности, путём перебора
-всех возможных комбинаций ошибочных частей. Данное значение конфигурации
-ограничивает число перебираемых комбинаций. Вы можете попробовать поднять
-его, если используете схему кодирования EC N+K с N и K, достаточно большими
-для того, чтобы число сочетаний `C(N+K-1, K-1) = (N+K-1)! / (K-1)! / N!`
-было больше, чем стандартное значение 100.
-
-Если возможных комбинаций слишком много или если корректная комбинаций не
-определяется однозначно, объекты помечаются неконсистентными (inconsistent)
-и не восстанавливаются автоматически.
-
-При использовании репликации перебор не нужен, Vitastor просто предполагает,
-что вариант объекта с наибольшим количеством одинаковых копий корректен.
-Например, если вы используете 3 реплики и 1 из них отличается, эта 1 копия
-считается некорректной. Однако, если "лучшую" версию с числом доступных
-копий большим, чем у всех других версий, найти невозможно, то объект тоже
-маркируется неконсистентным.

-
-    The hypothetical situation where you might want to disable it is when
-    you have 3 replicas and you are paranoid that 2 HDDs out of 3 may silently
-    corrupt an object in the same way (for example, zero it out) and only
-    1 HDD will remain good. In this case disabling scrub_find_best may help
-    you to recover the data! See also scrub_ec_max_bruteforce below.

-    версия - версия, доступная в большем числе экземпляров, чем другие. При
-    использовании кодов коррекции ошибок "лучшая" версия - это подмножество
-    частей данных и чётности, полностью соответствующих друг другу.
-
-    Гипотетическая ситуация, в которой вы можете захотеть отключить этот
-    поиск - это если у вас 3 реплики и вы боитесь, что 2 диска из 3 могут
-    незаметно и одинаково повредить данные одного и того же объекта, например,
-    занулив его, и только 1 диск останется неповреждённым. В этой ситуации
-    отключение этого параметра поможет вам восстановить данные! Смотрите также
-    описание следующего параметра - scrub_ec_max_bruteforce.
-- name: scrub_ec_max_bruteforce
-  type: int
-  default: 100
-  online: true
-  info: |
-    Vitastor can locate corrupted chunks in EC setups with more than 1 parity
-    chunk by brute-forcing all possible error locations. This configuration
-    value limits the maximum number of checked combinations. You can try to
-    increase it if you have EC N+K setup with N and K large enough for
-    combination count `C(N+K-1, K-1) = (N+K-1)! / (K-1)! / N!` to be greater
-    than the default 100.
-
-    If there are too many possible combinations or if multiple combinations give
-    correct results then objects are marked inconsistent and aren't recovered
-    automatically.
-
-    In replicated setups bruteforcing isn't needed, Vitastor just assumes that
-    the variant with most available equal copies is correct. For example, if
-    you have 3 replicas and 1 of them differs, this one is considered to be
-    corrupted. But if there is no "best" version with more copies than all
-    others have then the object is also marked as inconsistent.
-  info_ru: |
-    Vitastor старается определить повреждённые части объектов при использовании
-    EC (кодов коррекции ошибок) с более, чем 1 диском чётности, путём перебора
-    всех возможных комбинаций ошибочных частей. Данное значение конфигурации
-    ограничивает число перебираемых комбинаций. Вы можете попробовать поднять
-    его, если используете схему кодирования EC N+K с N и K, достаточно большими
-    для того, чтобы число сочетаний `C(N+K-1, K-1) = (N+K-1)! / (K-1)! / N!`
-    было больше, чем стандартное значение 100.
-
-    Если возможных комбинаций слишком много или если корректная комбинаций не
-    определяется однозначно, объекты помечаются неконсистентными (inconsistent)
-    и не восстанавливаются автоматически.
-
-    При использовании репликации перебор не нужен, Vitastor просто предполагает,
-    что вариант объекта с наибольшим количеством одинаковых копий корректен.
-    Например, если вы используете 3 реплики и 1 из них отличается, эта 1 копия
-    считается некорректной. Однако, если "лучшую" версию с числом доступных
-    копий большим, чем у всех других версий, найти невозможно, то объект тоже
-    маркируется неконсистентным.

-Дополнительные опции для команды подключения NBD-устройства:
-
-* `--nbd_timeout 30` \
-  Максимальное время выполнения любой операции чтения/записи в секундах, при

-  вы вообще не сможете отключить NBD-устройство при нештатном завершении процесса
-  vitastor-nbd.
-* `--nbd_max_devices 64 --nbd_max_part 3` \
-  Опции, передаваемые модулю ядра nbd, если его загружает vitastor-nbd
-  (`nbds_max` и `max_part`). Имейте в виду, что (nbds_max)*(1+max_part)
-  обычно не должно превышать 256.
-* `--logfile /path/to/log/file.txt` \
-  Писать сообщения о процессе работы в заданный файл, вместо пропуска их
-  при фоновом режиме запуска или печати на стандартный вывод при запуске
-  в консоли с `--foreground 1`.
-* `--dev_num N` \
-  Использовать заданное устройство `/dev/nbdN` вместо автоматического подбора.
-* `--foreground 1` \
-  Не уводить процесс в фоновый режим.
