Using dd I replicated the disk to two diffrent drives. One drive stored away and the other drive was going to be in the system being rsync'd nightly so that it would have the freshest data on it. Because of the dd the LVM had the same names and UUIDs for the vg and lg. I was able to change the names however I wasn't successful in change the UUIDs. It didn't even look like there was an option to change the UUIDs for the lv. What would have been the correct way to achieve a setup like this with LVM? I would assume a mirroring of some sort although I don't know what would be involved for the user if the drive did die and they needed to use the second drive. Thanks Ryan
