[NTLUG:Discuss] ext2fs problem

[Shane Allen]

Below is the output of two commands. Where I am stuck currently is that I am not terribly familiar with the filesystems... It's not something I've ever spent much time learning.

Do any of you have any sage advice for how I can go about repairing the drive (array)? Also, if you have a suggestion, what do you think the chances are that the suggestion will work, and what do you think the chances are that it will leave the drive unrecoverable? I don't expect perfect guesses here, obviously. TIA

[root at enterprise /root]# fsck /files
Parallelizing fsck version 1.19 (13-Jul-2000)

fsck.ext2: Input/output error while trying to open /files

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>
