October 24, 20205 yr I just noticed that one of my disks is showing "Unmountable: No file system" Not sure how or when this happened. Also not sure where to start on fixing the issue thor-diagnostics-20201024-1120.zip

Looks like it was unmountable when you booted up a few days ago. 5 minutes ago, biiiink said: where to start on fixing https://wiki.unraid.net/Check_Disk_Filesystems#Checking_and_fixing_drives_in_the_webGui
October 24, 20205 yr Wait a minute. Why didn't you mention you had a disabled disk? So, in addition to unmountable disk6 you have disabled disk10 you also didn't notice. Do you know how to fix that?
October 24, 20205 yr Author I didn't mention the disabled disk because i'm in the process of rebuilding it right now. I do have notifications set up but I don't see an email indicating the unmountable disk. I tested to make sure notifications still work, and they do
October 25, 20205 yr 7 hours ago, biiiink said: notifications set up but I don't see an email indicating the unmountable disk. There are different settings in Notifications for different kinds of events. I would think the array status notification would tell you about that, and Fix Common Problems probably checks that as well, but you have to configure it to send Notifications. I haven't had unmountable so I don't know for sure. Does Fix Common Problems have anything to say about your unmountable disk?
October 25, 20205 yr Author Im running the filesystem Check and it seems to be stuck. Phase 1 - find and verify superblock... couldn't verify primary superblock - not enough secondary superblocks with matching geometry !!! attempting to find secondary superblock... ..found candidate secondary superblock... unable to verify superblock, continuing... ....found candidate secondary superblock... unable to verify superblock, continuing... I read somewhere that this check can take a long time, but its been running for over 20 hours now.
October 25, 20205 yr Did disk10 rebuild complete yet? Since rebuild has to read all other disks it might be better to wait until after that rebuild to try the repair.
October 26, 20205 yr Author Its still showing as running. Its been about 40 hours and nothing has changed
October 26, 20205 yr FYI log is filled with ATA errors, on multiple disks, and parity is disable, but for now try runing xfs_repair manually, start array in maintenance mode and post output of: xfs_repair -nv /dev/md6
October 27, 20205 yr Cancel and try again after updating xfsprogs to latest, you can see the instructions here, but use the current release here.
October 28, 20205 yr Author Not sure how long it ran for but was less than 24 hrs, when running manually, eventually, I got this:
October 28, 20205 yr Author I updated xfsprogs, ran the repair again and still seeing the same thing as i saw initially. It's still running
October 29, 20205 yr You can cancel it, it won't work, weird part is that Unraid is attempting to mount the fs, but then xfs_repair can't find a valid superblock, never seen this before, you might be able to get some help on the xfs mailing list.
October 29, 20205 yr Also, make sure latest xfsprogs were installed by running: xfs_repair -V And don't forget to delete the extra folder.
October 29, 20205 yr Replacing the disk won't change anything, formatting is an option if the data there isn't important, or it can be restored from a backup.
