Added a new disk to the array today and stopped the clear that unraid was doing.

 

Now I'm getting Unmountable: not mounted

 

 

 

Jan 17 17:19:59 MirinServer root: mount: /mnt/disk1: wrong fs type, bad option, bad superblock on /dev/md1, missing codepage or helper program, or other error.

Jan 17 17:19:59 MirinServer emhttpd: /mnt/disk1 mount error: not mounted

 

I have done the below:

- Put array into maintenance mode
- xfs_repair -nv /dev/md1
- xfs_repair -vL /dev/md1

 

I didn't know what "Clear" was so I cancelled it. Not sure if this is what caused the above error or not. 

 

Any help would be appreciated.

 

Thanks

A ‘Clear’ is the action Unraid takes when adding a disk to a parity protected array as that is the action needed to ensure parity remains valid.

 

i am a bit confused as your screenshot shows only 1 data drive - were you trying to add disk2?   Has disk1 ever been formatted in Unraid?

Hi @itimpi Yes I was trying to add disk2. I have removed it from the array.

What was the output from the xfs_repair commands?

There's something mounting disk1 before the array:

 

Jan 17 17:06:58 MirinServer kernel: XFS (sde1): Mounting V5 Filesystem
Jan 17 17:06:58 MirinServer emhttpd: shcmd (3): /usr/local/emhttp/webGui/scripts/update_access
Jan 17 17:06:58 MirinServer sshd[1887]: Received signal 15; terminating.
Jan 17 17:06:59 MirinServer kernel: XFS (sde1): Ending clean mount

 

Then it cant be mounted again:

 

Jan 17 17:07:05 MirinServer kernel: XFS (md1): Filesystem has duplicate UUID eb78e917-4f51-464e-8114-d251dc7845f5 - can't mount

 

I had an unassigned SSD that changed its dev name. I have changed my boot script to use UUID instead.

 

Everything is now working as you can see below. 

 

 

Thanks for the help @JorgeB & @itimpi
