Running Kubuntu Dapper flight 6 on dual-core PIII. The hard drive is 120 GB.
This evening, while working on this computer, it started telling me that my
filesystem was read-only. I rebooted, and the system got as far as checking
the root filesystem, whereupon it gives me the following error:
/: UNEXEPECTED INCONSISTENCY; RUN fsck MANUALLY
(i.e., without -a or -p options)
When I execute fsck...
[EMAIL PROTECTED]: fsck
fsck 1.38 (30-Jun-2005)
e2fsck 1.38 (30-Jun-2005)
fsck.ext3: No such file or directory while trying to
open /dev/mapper/Ubuntu-root
The superblock could not be read or does not contain 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>
So I tried...
# e2fsck -b 8193 /dev/hda
and got the same message. I also tried 16384 and 32768 (based on the
information from man e2fsck -- I honestly don't know the blocksize on my
filesystem).
dmesg shows nothing useful. However, syslog has the following entries from
just before the system crashed:

What's really annoying is that the computer has suddenly decided it will no
longer boot from the CD-ROM drive, even though I have the BIOS set to boot
from CD-ROM, then the hard drive. Thus, I can't boot from the installation
media to attempt a system rescue there. I've tried booting using recovery
mode from GRUB, but I only get the same issues.
Any thoughts? This is a fairly old computer (five years old) so I guess all
manner of horrors, including a failed motherboard, are possible.
Got a floppy on that, try a Smart Boot Disk to get the CD to boot.

I'd also recommend if you have the hardware, put the drive into another
machine as a 2nd drive and run more in depth tools from a working OS.
Maybe try to read the S.M.A.R.T status too (if the drive has that).
Hopefully that'll get you started - Alex
