ext3 fs errors 3T fs

[Dennis Williams]

Hello,
I looked through the archives a bit and could not find anything relevant,
if you know otherwise please point me in the right direction.

I have a ~3T ext3 filesystem on linux software raid that had been behaving
corectly for sometime.  Not to long ago it gave the following error after
trying to mount it:

mount: wrong fs type, bad option, bad superblock on /dev/md0,
       or too many mounted file systems

after a long fsck which I had to do manually I noticed the following in
/var/log/messages after trying to mount again:

Jan 19 09:13:11 terrorbytes kernel: EXT3-fs error (device md0):
ext3_check_descriptors: Block bitmap for group 3584 not in group (block
0)!
Jan 19 09:13:11 terrorbytes kernel: EXT3-fs: group descriptors corrupted !

when trying to correct again with e2fsck I get this error:

e2fsck 1.34 (25-Jul-2003)
Group descriptors look bad... trying backup blocks...
e2fsck: Invalid argument while checking ext3 journal for /dev/md0

some more information on the system:
os flavor: Suse 9.1
kernel version: 2.6.5-7.202.7-default (various suse patches applied to
   2.6.5 kernel)

I am not sure where to go from here, any help, experience, or references
to documentation that would help me better understand the problem would be
apreciated.

Sincerely,
Dennison Williams
