EXT3-fs error: ext3_check_descriptors / group descriptors corrupted

kernelpanic-badfs.png

Operating System:

Red Hat Enterprise Linux 4 Update 5

What happened:

The server was abruptly powered down, disassembled, and re-assembled.

Work done:

Ran a fsck from the rescue environment and it eventually completed (after much corruption was found), but the server would not boot properly.

End result:

The damage to the filesystem could not be adequately repaired as the errors were very extensive. The RAID array had to be rebuilt and a new OS was installed.
