On LVM volume group names

Lior blogs about LVM volume group names colliding, after he'd done an installation on two systems with 'vg00' as the volume group name, and trying to add the hard disk from one of them to the other machine. Which breaks in all kinds of interesting ways, of course.

Me, I avoid the problem altogether by just naming my volume groups sensibly.

wouter@samba:~$ sudo vgdisplay|grep 'VG Name'
  VG Name               samba
[...]
wouter@goa:~$ sudo vgdisplay|grep 'VG Name'
  VG Name               goa

... etcetera. If I ever have to put one of the disks from goa's (500G) RAID array into samba, then that'll be no problem, at all.
