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>

sure, I thought of that too.

under /dev/VolGroup00 is LogVol00, LogVol01, LogVol02.

I do e2fsck -b 8193 /dev/VolGroup00/LogVol00 and I get the same super block error above.

Same with LogVol01 and 02.
