I had to replace the motherboard on one of my CentOS 4 systems and am now getting a kernel panic.
When I try to boot up, I get this:
Volume group “VolGroup00” not found
ERROR: /bin/lvm exited abnormally! (pid 448)
mount: error 6 mounting ext3
mount: error 2 mounting none
switchroot: mount failed: 22
umount /initrd/dev failed: 2
Kernel panic – not syncing: Attempted to kill init!
(I apologize for any typos, I don’t have a way to copy/paste from that screen)
I can boot up with the boot CD, go into rescue mode and browse the files, so I know the drives are ok.
I found some stuff online saying that I should recreate my initrd from rescue mode if the motherboard changed. I tried this, but am still getting the same results.
