I had such a collision once, but I was able to change the name of one
volume group by using vgrename with the UUID that vgdisplay shows. Dale,
unless you know about them already, check out {pv,vg,lv}{scan,display} for
information about your LVM.

I like to create several partitions, not a single one. And use pvcreate
for every partition then. This way, I can free space later just in case I
somehow need to have a conventional partition for installing Windows or
something. pvmove can transfer stuff from one physical volume to another.
I also used to have two volume groups. One small one for the system at
the start of the drive, where it is supposed to be a little faster, and
another big one for the rest. But I stopped doing so, as I lose a little
flexibility, and the effect is probably negligible, as all stuff is
encrypted here.
