我收到一条消息，说我的一个硬盘已降级，我正在尝试弄清楚如何检查它是哪个硬盘。我执行了 zpool status，得到了这个
zpool status
pool: BiggyD
state: DEGRADED
status: One or more devices could not be opened. Sufficient replicas exist for
the pool to continue functioning in a degraded state.
action: Attach the missing device and online it using 'zpool online'.
