Then there's the fun and games of trying to put one LVM disk into another box to read stuff from the drive. Dealing with two like-named volume groups seems even worse that coping with like-named volume labels.
Been bitten by this too. I ended up putting the disk back in the box it came from and renaming the volume group from rootvg to <hostname>vg, which is a practice I've followed ever since. Regards, Chris
