CentOS - Oct 2010 - Preserving LVM after after os reload

Hi guys,

I have two disks, one with OS and a second disk containing an LVM.  I
would like to OS reload the server without losing LVM.

I heard that LVM is self sustaining. Is that true ? Should I backup
something(using vgcfgbackup &  vgexport ?)  to get LVM running after
os reload.

Thanks in advance.

Sherin,

AFAIK you're safe as long as you obviously do not install on the LVM disk. 
Centos will pick up any LVM groups you have on that disk, you should be able 
to see it in Anaconda.
