raidz3 中的一个驱动器出现故障（pci-0000:03:00.0-scsi-0:0:10:0），我用一个可用的备用驱动器（wwn-0x5000c500858252ef）替换了它：
pool: darkpool
state: DEGRADED
status: One or more devices are faulted in response to persistent errors.
Sufficient replicas exist for the pool to continue functioning in a
degraded state.
action: Replace the faulted device, or use 'zpool clear' to mark the device
repaired.

我以为备用驱动器在重新镀银后会消失，并成为池中的一员。但这种DEGRADED状态仍然存在，备用驱动器仍在INUSE填补故障驱动器的空缺。
建议是replace the faulted device, or use use 'zpool clear' to mark the device as repaired.
我完全误解了这clear句话的意思。这是我的错误。我觉得我只是让事情变得更糟了。
pool: darkpool
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'.

我在最后一个空闲插槽中添加了另一个驱动器，wnn-0x5000cca26788a8f8但是我应该在这里替换什么呢？

我相信该池是在 Ubuntu 14.04 上创建的
History for 'darkpool':

不，我不知道是谁设置了这些名字，我更喜欢 by-id，尽管在 Ubuntu 18 中它似乎不再重要了。
答案1
您可能过早地清除了 zpool 错误（重新镀银正在进行中）但是，您不应该对池健康造成任何损害。
让您的池重新镀银，然后发出zpool clear darkpool并最终执行zpool scrub darkpool。这应该足以拥有一个干净的池。
