我的 ZFS 池中有两个故障磁盘，我用zpool replace. 如何识别故障磁盘以便进行物理更换？
以下是我在损坏的磁盘上zpool status运行之前和之后的输出。zpool detach
之前zpool detach：
pool: mypool
state: DEGRADED
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.
scan: resilver in progress since Tue Jun 7 11:26:56 2016
123M scanned out of 91,8T at 5,84M/s, (scan is slow, no estimated time)
5,23M resilvered, 0,00% done
