Hi,
I had 2x750GB drives in a RAID1 configuration in a D-Link NAS
(DNS-323) device with embedded Linux as an ext2 volume. The
configuration was corrupted and the NAS no longer saw the RAID.
I put the drives in another Linux box and was able to use mdadm to
scan the drives. It recognized the RAID1 configuration and created the
RAID device at /dev/md0. Unfortunately, it says it is corrupt and
cannot be mounted. I tried using e2fsck / fsck but it says the
superblock is corrupt. Trying to use copies of the superblock were
unsuccessful.
I am confident the data is still there and want to get to it. Is there
a way to take one of the drives and convert it from being in the RAID1
set to just a standard ext2 partition in a non-destructive way? I
figured this should be possible with the second drive just to be sure
not to destroy both copies of the data.
Try a read-only loopback mount of the partition (either). However, I
think you're missing something else, although I don't have a clue what.
Unless the O/S started writing bad data or the hardware got sick, you
should be able to recover. In any case this allows you to do something
non-destructive and use offset= depending on the superblock location.
