hi guy's. i new in your mailing list and i have a problem with my setup. today my raid5 degraded totaly and i can fix it with a command to re-created mdadm --create /dev/md2 --assume-clean --verbose --level=5 --raid-devices=4 /dev/sdc1 /dev/sdd1 missing /dev/sdf1 After this i add my /dev/sde1 also to my /dev/md2 device. My problem is now the i cannot open my crypt device cryptsetup luksOpen /dev/md2 md2_nas Device /dev/md2 is not a valid LUKS device. Befor one year i has the device created with this command: luksformat -t ext4 /dev/md0 A dont have a backup of the header. Is the filesystem broken? fsck /dev/md2 fsck from util-linux 2.20.1 e2fsck 1.42 (29-Nov-2011) fsck.ext2: Superblock invalid, trying backup blocks... fsck.ext2: Bad magic number in super-block while trying to open /dev/md2 Is there a chance to get my data from the device? Thank you. |
