Kernel Panic after Power Loss


I was running FC6 when the power failed at my house. I started the machine up again and it said:

Code:
2 logical volumes in volume group "VolGroup 00" now active
VFS: Can't find ext3 filesystem on dev dm-0
mount: error mounting /dev/root on /sysroot as ext3: Invalid argument
setuproot: moving /dev/ failed: No such file or directory
setuproot: error mounting /proc failed: No such file or directory
setuproot: error mounting /sys failed: No such file or directory
switchroot: mount failed: no such file or directory
Kernel panic - not syncing: Attempted to kill init!
I dual boot xp and FC6. XP starts with no problems. I havent done anything to fix this yet because frankly, i'm afraid of making it worse. I've read around the board about other kernel panics with similar messages, but nothing seems to fit my situation. This is the first problem i've had of this nature.
I'd greatly appreciate any help you could give me.

try getting a live cd and fsck'ing your partitions

sounds like to me the power outage occured when you were doing something file-intensive, and the file system was damaged very badly, or the disk heads didn't retract and damaged your disk.

Warning Running fsck on a logical volume's partition will destroy the logical volume and render it unusable and unrecoverable.

To run fsck on your root file system you need to:

1) Boot from the Fedora rescue CD (or, if you have a DVD, boot with linux rescue at the first prompt.

2) Unmount the root partition mounted in /mnt/sysroot

3) Run fsck /dev/mapper/VolGroup00/LogVol00 (If I recall correctly. Do a ls /dev/mapper for the actual names.) Note that "VolGrp00" will, by default, contain two logical volumes: The swap device and the root file system.

If the rescue system can't find any logical volumes (or if dm, the "device mapper," can't access them (which may be the case from your error messages)), then you'll either need to read about recovering a damaged logical volume or, more likely, need to reinstall your FC6 -- loosing all your data.

Some tools are available for recovering files from a damaged logical volume, but I've never been successful when I tried to use them.

There are also backup tools available, and, if you have a recent backup, you might try reinstalling (or, better, installing F8) and restoring your home directory from the backup.

Note: FC6 is, I believe, obsolete and no longer supported by the Fedora project.

I struggled with it for a couple of weeks and finally gave up. I started over from scratch. I appreciate everyone's advice. People here have saved me in the past.
PTrenholme, that seems like a good idea, i wish i had tried that.
