ZFS 導入後記憶體設備不正確

我最近從 Ubuntu 機器遷移到 Arch Linux 機器。

我使用 導入了池zpool import -f tank，它報告我的記憶體驅動器出現故障，但我的儲存驅動器工作正常。它是一個帶有 5 個驅動器的 raidz2。奇怪的是，它報告錯誤的驅動器作為記憶體。它的上市sde，應該是什麼時候sdg。請注意，sde它也被列為儲存設備。

   ❯ 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'.

我的實際記憶體驅動器正在愉快地等待使用：請參閱 /dev/sdg：

我不確定如何用正確的驅動器替換記憶體驅動器。替換命令拋出錯誤：

sudo zpool replace tank sde  
/dev/sde is in use and contains a unknown filesystem.

我嘗試添加實際的記憶體驅動器並收到此錯誤：

❯ sudo zpool add tank cache /dev/sdg
cannot add to 'tank': one or more vdevs refer to the same device

zdb 輸出未列出記憶體設備

您可以考慮使用/dev/disk/by-id名稱而不是標準 SCSIsd*名稱導入池。由於您的作業系統移動和不一致的設備列舉，/dev/sd* 名稱不是確定性的，並且可能會更改。

這是如何執行此操作的範例：https ://unix.stackexchange.com/q/288599/3416
