EXT3-fs error: ext3_check_descriptors / group descriptors corrupted
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.
