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。
