Hi, I followed the perfect setup for CentOS and upon yum update (right at the beginning after OS installed) and doing a reboot I got this error message. Unable to find volume group "VolGroup00" ERROR: /bin/lvm exited abnormally (pid 213) 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 got a P4 32bit machine running and adaptec 1420 SATA2 raid controller card. Use automatic disk partitioning with LVM and 2000MB of swap space. This is the third time I got the error after 3 reinstallations. Strange thing is that during one of my earlier installation, it was okie. Not sure if I selected any different options or package or did a step differently. Anyone can shed a little light to this? Thanks in advance. linux rocks!
