我在 hetzner cloud arm 机器上有一个 ubuntu 22.04 系统，一直出现 zfs 错误，我有点不知道问题出在哪里。
zpool status -v
pool: encpool
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

它通常显示如上。我执行了 zfs scrub encpool，第一次完成时显示相同的错误。然后我重新运行它，现在显示为 OK：
zpool status -v
pool: encpool
state: ONLINE
scan: scrub repaired 0B in 00:01:56 with 0 errors on Sun Feb 4 21:02:48 2024

raidz1-0 ONLINE 0 0 0
sdb ONLINE 0 0 0
sdd ONLINE 0 0 0
sda ONLINE 0 0 0
errors: No known data errors
这种情况已经发生过几次了。scrub 有时会立即见效，有时会在运行 2 次之后才见效。
sdx 磁盘是 hetzner 云卷，它们本身应该是冗余的（每个数据块都存储在三个不同的物理服务器上）。encpool 已加密并且已打开压缩，但没有打开重复数据删除。它配置为 raidz1。
