My ZFS pool missed after power lost last night.

The followings is displayed when I issue command zpool status
pool: zdata
state: FAULTED
status: The pool metadata is corrupted and the pool cannot be opened.
action: Recovery is possible, but will result in some data loss.
Returning the pool to its state as of 日 8月/30 17:08:21 2020
should correct the problem. Approximately 1 seconds of data
must be discarded, irreversibly. Recovery can be attempted
by executing 'zpool clear -F zdata'. A scrub of the pool
is strongly recommended after recovery.

Sorry, I meant to type zpool status -v.

Regardless, you need to get your backups out and restore. You're wasting time here trying to figure out the problem, IMO.
 
I can use more time to recover the data. Is it possible to recover data from faulted zfs pool? The result of command zpool status -v is same
