Hello,
yesterday on a routine reboot with my raid server I got the following
message:
EXT2-fs error (device 09:00): ext2_check_descriptors: Block bitmap fo
not in group (block 3670099)!
EXT2-fs: group descriptors corrupted !
I tried to fsck /dev/md0 but all I'm getting is
e2fsck 1.12, 9-Jul-98 for EXT2 FS 0.5b, 95/08/09
Group descriptors look bad... trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/md0
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
but e2fsck is not happening with:
e2fsck: Bad magic number in super-block while trying to open /dev/md0
So now I'm at odds. How do I fix the file system? It seems that
everything is there but I can't access it.
The system: debian 2.1, Linux 2.2.1
