Volume group “VolGroup00” not found

Reading all physical volumes. This may take a while…┬áVolume group “VolGroup00” not found

 
Unable to access resume device (/dev/VolGroup00/LogVol01)
mount: could not find filesystem '/dev/root' 
setuproot: moving /dev failed: No such file or directory 
setuproot: error mounting /proc: No such file or directory s
etuproot: error mounting /sys: No such file or directory 
switchroot: mount failed: No such file or directory Kernel panic - not syncing: Attempted to kill init! 

basically initrd didn’t have the right drivers to access the file system.
boots from the CD follow the instructions to enter Linux Rescue (usually you type “linux rescue” at the boot prompt)

Now we can rebuild initrd with the missing drivers.

# chroot /mnt/sysimage

# cd /boot

# mkinitrd -v -f initrd

Now hit tab and it will auto-complete then add the text that was autocompleted when you hit tab except for the .img

So your command should look like:

# mkinitrd -v -f initrd2.4.18-19.8.0.img 2.4.18-19.8.0

# exit or reboot
