Can anyone point me in the right direction for correcting errors on an HD when using LVM? I've tried e2fsck and indicates bad block. I've tried with -b 8193, 16384, and 32768 and no good.

I've found some info about reiserfsck on google, but this utility doesn't seem to be included in Centos4.3. I did find it on my old FC1 box.

I am thinking now I really should have went with just regular 83 Linux ext3 partitions. Arrgghhh.

And if I want to switch to 83 Linux instead of 8e LVM, whats the best way, or at least a feasible way? I can pop another drive in if I need to move data around, but I don't see how, as I can't mount the LVM partition (hda2).

As the previous poster advised, this is probably a hardware fault but for your reference I used the same instructions from this post to fix a corrupt filesystem within LVM.

Use a Centos rescue disk

1) Do startup network interfaces 2) Don't try to automatically mount the filesystems - not even readonly 3) lvm vgchange --ignorelockingfailure -P -a y 4) fdisk -l, and guess which partition is which based on size: the small one was /boot, and the large one was / 5) mkdir /mnt/boot 6) mount /dev/hda1 /mnt/boot 7) Look up the device node for the root filesystem in /mnt/boot/grub/grub.conf 8) A first tentative step, to see if things are working: fsck -n /dev/VolGroup00/LogVol00 9) Dive in: fsck -f -y /dev/VolGroup00/LogVol00 10) Wait a while... Be patient. Don't interrupt it 11) Reboot
