Hi Guys,

I precleared disk5 then rebuild the array, parity show valid and finding 0 errors but now my disk5 is unmountable. I had some file corruption on disk6 before which I already corrected with file system check so not sure if that cause any issue. Attached is the log file. Any help and suggestions would be appreciated.

You need to check filesystem on disk5:

Ran check files system on disk5 then with rebuild tree option two times but both seem to be stuck at the same spot and didn't finished. My array maybe corrupted that's why it didn't rebuild disk5 correctly. What should be my approach? Thanks for the help.

Post the output of reiserfsck

Here's the log:

There's no error so can't guess the problem, try running reiserfsck on another computer and/or with unRAID v6.2.4 as it includes an earlier release of reiser-progs, use a trial key on another PC if you don't have another server available.

Edited February 27, 20179 yr by johnnie.black

Is downgrading to unRAID v6.2.4 from v6.3.2 a simple process? Can you point me in the right direction?

Downgrade itself is very easy, just replace the 3 bz* files with those from v6.2.4 and reboot, if you use dockers and/or VMs some additional steps my be needed for them to work (or upgrade again after running reiserfsck)

Johnnie.black, you are the man! Thank you. I got it working again. I suspect I my array still has some file corruptions. What's the best way to check this?

If all disks are reiser run reiserfsck --check on all of them, if any corruptions are found use the option mentioned by the reiserfsck output.
