ZFS Automatic Scrub/Trim for Linux.
|
||
This package is ported from debian to facilitate use on other
|
||
distributions. This package renames some properties to make them more
|
||
consistent when used with zfs-auto-snapshot.
|
||
Auto TRIM is implemented using a custom per-pool property:
|
||
com.sun:auto-trim
|
||
By default, these TRIM jobs are scheduled on the first Sunday of every
|
||
month. The completion speed depends on the disks size, disk speed and
|
||
workload pattern. Cheap QLC disks could take considerable more time than
|
||
very expensive enterprise graded NVMe disks.
|
||
When com.sun:auto-trim is not present in pool, or the property is
|
||
present but value is empty/invalid, they are treated as auto.
|
||
Auto Scrub is implemented using a custom per-pool property:
|
||
com.sun:auto-scrub
|
||
By default this have a cron job entry to scrub all pools on the second
|
||
Sunday of every month at 24 minutes past midnight.
|
||
See /etc/cron.d/zfsutils-linux and /usr/libexec/zfs/scrub for details
|
||
It is possible to disable this by setting a zfs user defined property on
|
||
the root dataset for a pool.

适用于 Linux 的 ZFS 自动清理/修剪。
|
||
这个包是从debian移植来的，方便在其他平台上使用。这个包重命名了一些属性，
|
||
使它们与 zfs-auto-snapshot 一起使用时保持一致。
|
||
自动修剪 (TRIM) 是使用自定义的每个池属性来实现的：
|
||
com.sun:auto-trim
|
||
默认情况下，这些 TRIM 作业安排在每个月的第一个星期日。完成速度取决于磁盘
|
||
大小、磁盘速度和工作负载模式。廉价的 QLC 磁盘可能比昂贵的企业级 NVMe
|
||
磁盘花费更多的时间。
|
||
当 com.sun:auto-trim 不存在于池中，或者该属性是存在但值为空/无效，它们被
|
||
视为自动。
|
||
自动清理 (SCRUB) 是使用自定义的每个池属性来实现的：
|
||
com.sun:scrub
|
||
默认情况下，它有一个 cron 作业条目，用于在每月第二个星期日午夜过后
|
||
24 分钟清理所有池。
|
||
有关详细信息，请参阅 /etc/cron.d/zfsutils-linux 和
|
||
/usr/libexec/zfs/scrub.
|
||
可以通过在池的根数据集上设置 zfs 用户定义的属性来禁用此功能。
