EXT3-fs: group descriptors corrupted


i reinstalled my system. when i tried to remount my array, i got the following error:

mount: wrong fs type, bad option, bad superblock on /dev/md0,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

dmesg | tail says:

[ 576.644867] EXT3-fs error (device md0): ext3_check_descriptors: Block bitmap for group 3982 not in group (block 0)!
[ 576.679393] EXT3-fs: group descriptors corrupted !

anything i can do?

Have you fsck'ed the /dev/md0 ? I mean, manually ? At the first run, try a dry-run with the key -n, valid only for ext2/ext3. In this way you can, in advance, see what/how fsck will try to fix your fs and decide what to do based on that.

good luck !
