在遇到ZFS存储池因数据损坏无法挂载时，可以尝试使用`zpool import -d`命令配合不同选项进行修复。在确认可能的数据丢失风险后，使用`zpool import -F`强制挂载，然后进行数据恢复和池扫描。
bash-4.1# zpool import -d /dev/disk/by-id
pool: data
id: 16015589977926012805
state: FAULTED
status: The pool metadata is corrupted.
action: The pool cannot be imported due to damaged devices or data.
The pool may be active on another system, but can be imported using
the '-f' flag.
see: http://zfsonlinux.org/msg/ZFS-8000-72
config:
data FAULTED corrupted data
dm-name-VolGroup-lv_data ONLINE
bash-4.1# zpool import -d /dev/disk/by-id data
cannot import 'data': I/O error
Recovery is possible, but will result in some data loss.
Returning the pool to its state as of Thu Jun 28 19:53:45 2018
should correct the problem. Approximately 5 seconds of data
must be discarded, irreversibly. Recovery can be attempted
by executing 'zpool import -F data'. A scrub of the pool
is strongly recommended after recovery.
bash-4.1# zpool import -f -d /dev/disk/by-id data
