BTRFS pool not mounting after a power outage

BTRFS
1

My power recently went out, and after bring my NAS back online (10 disk array in RAID 10), my main pool will not mount. Here is the output in dmesg:

[ 117.709153] BTRFS error (device sde): parent transid verify failed on 83678019223552 wanted 2270643 found 2270261
[ 117.709678] BTRFS error (device sde): parent transid verify failed on 83678019223552 wanted 2270643 found 2270261
[ 117.709787] BTRFS error (device sde): failed to read block groups: -5
[ 117.721830] BTRFS error (device sde): open_ctree failed

I’ve tried searching around, but can’t seem to find anything about how to fix from this situation. I’ve like to try and recover from this, if at all possible, rather than start the process of restoring from backups (which for me are all in the cloud).

I’ve tried a mount -o degraded and mount - o degraded,ro but both fail with the same dmesg output.

If anyone has any thoughts, I’m open to them.

Hi @kupan787,

Is this on your rockstor_rockstor pool, or one of your RAID pools?
If are able to boot the system (rockstor_rockstor pool working) Try running a btrfs dev scan (post the output here) and then mounting again.
If that’s successful, try checking the S.M.A.R.T data of each of the disks, smartctl -a /dev/<disk>
Post results.
