我对 ZFS 很陌生，所以也许我读错了。
重新启动我的服务器后，我不得不重新导入我的池，并且在执行某些操作时出现了这种状态：
# zpool status -v
pool: data
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'.

引起我注意的是in的FAULTED音量raidz1-0，但我没有注意到它是 /dev/sdb，但/dev/sdb目前正在使用raidz1-2！
因此，我正式导出了池，强制打开 labelclear/dev/sdb并呈现以下状态：
# zpool status
pool: data
state: ONLINE
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.

我有两个问题
- 这怎么发生的
- 大概这意味着我在某处丢失了磁盘？识别它的最佳方法是什么？
附加信息：这个服务器+启动应该有12个数据盘，但是blkid只有11个。
