我最近从 Ubuntu 机器迁移到了 Arch Linux 机器。
我使用 导入了池zpool import -f tank，它报告我的缓存驱动器有故障，但我的存储驱动器工作正常。它是一个有 5 个驱动器的 raidz2。奇怪的是，它将错误的驱动器报告为缓存。它列出了sde，而它应该是sdg。请注意，sde也被列为存储设备。
❯ zpool status
pool: tank
state: ONLINE
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'.

我的实际缓存驱动器正高兴地等待使用：参见/dev/sdg：

我不确定如何用正确的驱动器替换缓存驱动器。替换命令会抛出错误：
sudo zpool replace tank sde
/dev/sde is in use and contains a unknown filesystem.
我尝试重新添加实际的缓存驱动器并收到此错误：
❯ sudo zpool add tank cache /dev/sdg
cannot add to 'tank': one or more vdevs refer to the same device
zdb 输出未列出缓存设备

/dev/disk/by-id您可以考虑使用名称而不是标准 SCSI名称来导入池sd*。由于您的操作系统移动和不一致的设备枚举，/dev/sd* 名称不确定，可能会发生变化。
