我想知道为什么我的两个新驱动器比其他 6 个驱动器大，却显示相同的校验和错误。在调查这个问题时，我注意到 UUID 都相同。像这样有相同的 UUID 正常吗？
$ zpool status
pool: nas
state: DEGRADED
status: One or more devices could not be used because the label is missing or
invalid. Sufficient replicas exist for the pool to continue
functioning in a degraded state.
action: Replace the device using 'zpool replace'.

答案1
这是您的 ZFS 池的 UUID。您可以使用 查看它zdb。请注意UUID_SUB值。这些是成员 UUID，您也可以使用 查看它们zdb。
例子：
$ blkid /dev/sdc4

是的，这是完全正常且预料之中的。
