[K12OSN] ext3-fs errors, server not booting

[Joseph Bishay]

Hello,

Question - I have a FC3 ltsp server (k12ltsp) that, after a reboot,
won't boot up. It is a hardware SCSI RAID 1 on two SCSI drives. Upon
rebooting, it drops me into a Grub prompt.  When I boot up in knoppix,
I can see 2 scsi drives, but trying to mount them fails. When I check
dmesg, I see the error ext3-fs group descriptors corrupted.  So it
seems it be an issue where the bootup sequence cannot find init.  I'm
not sure how to proceed from here though. I'm weary of running fsck on
the drive since I've known that to completely trash the drive data,
but I'm not sure if installing grub from the prompt will be the right
solution.

Wisdom?

thanks.
Joseph
