I'm not sure what this error is. I've attached diags. The only thing I see is that I can't mount a drive via unassigned devices.

Check filesystem:

https://wiki.unraid.net/Check_Disk_Filesystems#Drives_formatted_with_XFS

Running it on the drive I was trying to mount:

 

root@Unraid:~# xfs_repair -v /dev/sdo
Phase 1 - find and verify superblock...
bad primary superblock - bad magic number !!!

attempting to find secondary superblock...
.found candidate secondary superblock...
unable to verify superblock, continuing...
.found candidate secondary superblock...
unable to verify superblock, continuing...
.found candidate secondary superblock...
unable to verify superblock, continuing...

Now it appears to be scanning the rest of the drive.

The xfs_repair command is wrong!

 

if checking an array drive you should do it in Maintenance mode and use /dev/mdX as the device (where X is the disk number) as that maintains parity.   If checking a disk that is outside the array then you need to include the partition number (e.g. /dev/sdo1).

xfs_repair -v /dev/sdo

You need to specify the partition:

 

xfs_repair -v /dev/sdo1

 

 

 

I've tried it with the command specifying the partition. Nothing changed. I still wasn't able to mount the drive.

 

I looked in the logs again and I saw a new error saying there was a duplicate UUID for /dev/sdo.

I rebooted the array and everything is fine again. Not sure what happened.
