i have a backup from the three devices and i switched back to partion
case 1 and i fire up the fsck:

fsck -y /dev/mapper/md2_nas
fsck from util-linux 2.19.1
e2fsck 1.41.14 (22-Dec-2010)
fsck.ext4: Group descriptors look bad... trying backup blocks...
The filesystem size (according to the superblock) is 1465134336 blocks
The physical size of the device is 1465133568 blocks
Either the superblock or the partition table is likely to be corrupt!
Abort? yes

thats all?
is my chance on case 1 over?

should i try a fsck -a?

No, go to case #2.
