我的 ZFS 池中有两个故障磁盘，我用 zpool replace 替换了热备件。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运行zpool detach 前后zpool status 的输出。
zpool detach之前：
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

最好将问题移至 unix.stackexchange.com，因为 stackoverflow 更适合程序员，而不是系统管理员。
-
@MichaelZhilin 如何移动它？
-
afaik，版主。我认为您可以在 unix 网站上重新发布它。
