Here's some helpful info from Posts on the Fedora Forum. They are talking about Fedora 11. But they also mention ext4 and ext3 file systems. Be careful though. Don't do anything like running "fsck" on a Mounted Files System like this guy did did!:O I wouldn't run any of the commands they mention unless I understood what was going to happen either...
LVM Crashed after fsck on root partition
Hi, I am new in this forum but please help me,
I got 2 HDDs, I had created LVM by two of them. When I was trying to install quota it was saying it is better if you run fsck first message. When I tried to run fsck. It warned me that I could lose some of my data. So it happened. Actually it is worse:
I can't boot my Fedora 11. When I try to run installer in rescue mode, it says no Linux partition find.
When I try to install (just to see partitions) it shows LVM volumes of hdds are ok but the partition which is / (root)partition seems in unknown format.
How can I save my datas? Or can i restore my partitions, LVM?

lvm lvchange -a y
# this only activates the LV's on all VG, and your LVM should already be know so it is not necessary.
#fsck.ext4 or fsck.ext3 or e2fsck
# e2fsckwill determine the type.
e2fsck /dev/VolGroup00/LogVol00
e2fsck /dev/mapper/VolGroup00-LogVol00
fsck.ext4 /dev/VolGroup00/LogVol00
fsck.ext4 /dev/mapper/VolGroup00-LogVol00
# mount after fsck is done.
# use mapper
mount /dev/mapper/VolGroup00-LogVol00 /mnt/somemountpoint
# does not work use /dev path
mount /dev/VolGroup00/LogVol00 -t ext4 /mnt/somemountpoint

thank you it worked. "e2fsck -y /dev/VolumeGroup/LogicalVolume" is running now

I run e2fsck and it went in an infinite loop, there are many numbers pozitives and negatives. Is this normal? What should I do? I tried fsck.ext3 and fsck.ext4 as well.

After the meaningless numbers, it has ended and said fixed.
The size of the lost+found folder is 43GB, far enough for me. It rescued my critical files, thanks everyone (especially SlowJet) who helped me on this.
