A description of the problem
- Description
The j4200 and the x4150 connected to it were powered off
and then moved to another building with the utmost care. When powered on
again 'zpool status' revealed " corrupted data" on 3 of the disks.
Outputs:
zpool status
pool: pool2
state: FAULTED
status: One or more devices could not be used because the label is missing
or invalid. There are insufficient replicas for the pool to continue
functioning.
action: Destroy and re-create the pool from a backup source.

r...@x4150:~# zpool scrub pool2
cannot scrub 'pool2': pool is currently unavailable
All I want to know is if there is ANYTHING I can do to recover the data
in this pool?
start with running
zdb -u pool2
zdb -bcsv pool2
it is a good idea to redirect output (along with stderr) of the second
command to some file. It can take a while to run, but upon completion
we'll have better idea what blocks are corrupted and what can be done.

victor
