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.
Sorry, hit <send> and had another thought: I think you said you rebuilt the initrd... *could* you see the drives? *Did* the running system you rebuilt from have all the LVM drivers loaded when you rebuilt it?
I can see the drives from the rescue environment. I don't know how to check the LVM drivers.
You need *both* the md drivers and lvm drivers. I haven't built a system using lvm in years, I'm afraid, but it shouldn't be too hard.
Btw, this may be of some interest: http://www.centos.org/docs/5/html/Cluster_Logical_Volume_Manager/device_mapper.html
