Some Drives have reverted to old Partition layout

Open MasterCATZ opened this issue 4 years ago • 1 comments

Unsure what has happend but Ubuntu is confused at what it is looking at and unable to mount some btrfs file systems and seems to be looking at old partitions from years ago

sudo mount -o rescue=usebackuproot /dev/mapper/SRD2NA1B1-part1 /mnt/repair
mount: /mnt/repair: wrong fs type, bad option, bad superblock on /dev/mapper/SRD2NA1B1-part1, missing codepage or helper program, or other error.

the current Partition layout should be 2 meg free space at start of the partition and 3 meg free space at the end with matching partition / label names and should be /dev/mapper/SRD1NA1B2-part1 with label SRD1NA1B2

unsure which uuid is correct

45db86a1-3ccd-4687-beb9-8b7c8ccc9f6c (what Ubuntu See's) or 0a4a46d2-fe5d-4c67-9cb7-8253f1bc4903 (What btrfs see's) or multipath { wwid 3500605ba00b98ff0 alias SRD2NA1B1

the drives still working all have matching UUID between Ubuntu and BTRFS

ufs explorer professional recovery loads up the drive just fine

I still can not get it to mount

sudo btrfs rescue super-recover -v /dev/sdbp1
