Hi everyone. I set up LVM today and everything went fine until I rebooted the computer.
After the reboot the volume group was not in /etc/fstab anymore and the vgdisplay command didn't give any output. I searched around and found out that I had to reactivate my volume group using vgchange -a y VolGroup00

I did that and everything was working again (i.e. was able to mount the volume group).

I have to reactivate it everytime I reboot now, I couldn't find any solutions on the web. A guy had the same problem in another forum but he initially changed something on the /etc/lvm/lvm.conf file and when he replaced it with the original one his problem went away. I haven't touched any config files. Have I miss anything during the set up?
Any suggestions please?

Here is the output of vgdisplay
