I recently ordered a brand new PowerEdge T105 server which came with an 80 GB hard disk. I partitioned it with LVM, installed Debian Lenny and moved over the bulk of my things from the old server to the new server. Only one thing remained: my media collection, which is stored on a 500 GB RAID1 array on the old server. That RAID1 array is also partitioned using LVM in a single 500 GB volume group. I wanted to move the OS volumes from the 80 GB volume group to the 500 GB volume group. Problem: There is no obvious way to move a logical volume from one volume group to another. Cue SytemRescueCD.
