Hey All

I'm definitely still learning Unraid / Servers etc. I was trying install a new m.2 drive in my cache pool folowing instructions from the link below.  in the process it seems I have messed up the filesystem on the drive.  The original drives are back in my system.  I've been exploring the forum all night and tried the following commands:

 

btrfs-select-super -s 1 /dev/nvme1n1

       No valid Btrfs found on /dev/nvme1n1
       Open ctree failed

mount -o rescue=all,ro /dev/nvme1n1 /temp

        mount: /temp: wrong fs type, bad option, bad superblock on /dev/nvme1n1, missing codepage or helper program, or other error.

mount -o degraded,rescue=all,ro /dev/sdX1 /temp

         mount: /temp: wrong fs type, bad option, bad superblock on /dev/nvme1n1, missing codepage or helper program, or other error.

btrfs check --repair /dev/sdX1

       Errors out

 

Its not the end of the world if I loose the data it was just my appdata folder, I would reather not loose my plex server if possible but if that has to happen it won't be the end of my world.

 

Again sorry for possible extreme noobness
