Fedora and LVM

I've seen similar issues on mailing lists when a hard disk from one Fedora machine is plugged into another Fedora machine - since they both use the default VG and LV names, much confusion results and it's not easy to recover from.

One tip for using LVM is to never use the default VG and LV names, to avoid this sort of thing.

I've lost far more time (and data) due to LVM complexities/issues than I have saved through easy expansion/moving of FSs. It makes upgrades and transferring to new PCs much more complex.
