"No Volume Exists" After 6.9.3 Lockup
Hi,
Recently updated my NAS to 6.9.3 and found it locked up.
Unable to reboot it I had to drop power.
Not have the message "No Volume Exists"
Checked logs dmesg.log
[Sun Mar 25...
Check volume with ubuntu and was able to see data still there (plugged all 6 drives into test rig)
put back into nas and ran
btrfs check --repair /dev/md127
rebooted once completed and all data is back again.
Unfortunatly its a few months old as moved house and havent unpacked/found backup drives yet....:(

- Running that command is risky.
Like zero-log it can bake in corruption.
See e.g. https://btrfs.wiki.kernel.org/index.php/Btrfsck
I would suggest you check your data to verify that it is in a good state.
