我有一个当前状态的 ZFS 池:
[root@zfs01 ~]# zpool status
pool: zdata
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'.

如您所见,我已通过命令添加了备用磁盘“ata-HGST_HUH728080ALE604_2EGWD3WX”,zpool replace zdata /dev/disk/by-id/ata-HGST_HUH728080ALE604_2EGWHSGX /dev/disk/by-id/ata-HGST_HUH728080ALE604_2EGWD3WX
该命令现已创建了一个spare-1
包含两个磁盘的设备(希望备用驱动2EGWD3WX
器能够替换损坏的驱动器2EGWHSGX
。)
我现在该如何移除坏掉的驱动器ata-HGST_HUH728080ALE604_2EGWHSGX
?
答案1
要用热备件替换故障磁盘,您zpool replace
根本不需要这样做(事实上,这可能会给您以后带来各种麻烦;我从来没有这样做过)。相反,您只需更换zpool detach
故障磁盘,热备件就会自动替换它。
