Hi All, here's my situation:
Had a 2-bay Synology Diskstation with 2 x 2TB drives. Synology uses mdadm to store files, in this case Raid1.
The box crashed and array was damaged somehow. Drive's showed errors as well (ATA).
ddrescued one of the drives to a new health 2TB drive, tried to reassemble, mdadm reports bad superblock. (same as when trying with original disks)
So as of right now I'm scanning for Superblocks with PhotoRec(testdisk).
My first question is: will testdisk be able to recover files from the non-assembled/mounted mdadm array? Can it even see those files without a /dev/mdX to scan?
Second question - assuming it recovers a backup Superblock, how can I use that to get the raid back up?
Thanks in advance!
