Hi everyone,

I have run into some serious problems trying to start up RHEL AS4. I am trying to install Oracle on this box which by the way is running as a guest OS through VirtualBox. I was running with it fine yesterday. I was doing the prerequisites of updating the /etc/sysctl.conf file with additional kernel parameters. Prior to that I added another scsi virtual disk and extended a PV and left it at that for the night. I am since come back today and trying booting and am getting the following errors:

Volume group "VolGroup00" not found;
Couldn't find all physical volumes for volume group VolGroup00;
Couldn't find device with UUID "Some UUID of the device";
ERROR: /bin/lvm exited abnormally! (pid 318);
mount: error 6 mounting ext3;
mount: error 2 mounting none;
switchroot: mount failed: 22
umount /initrd/dev failed: Z
kernel panic - not syncing: Attempted to kill init!

I have tried running in rescue mode and it can find volume group VolGroup00. I also have installed Storage Foundation which includes veritas volume manager and other various veritas components.

Does anyone have a clue what I am supposed to do here to get RHEL up and running again?

I am running kernel version 2.6.9-42.EL if that helps as well.

All ideas are welcome and will be greatly appreciated.

Many Thanks
