In my research on related to my previous question about "un-lvm-ifying" a partition, I found these interesting articles.<br><br>1. Mount a disk image that exists as a file; in this case, a XEN xvda device. We assume that, like a real disk, this file contains a partition table.<br>

Take a disk image that exists as a file and contains LVM partitions, activate the LVM partitions, and mount them accordingly:<br>

Then, I reformatted the 500G disk with one ext3 partition. Using the second article I mounted the "LVM-on-a-file" and copied all of my stuff back to the 500G disk.<br>
<br>Among this data, was a xvda file for my old mailserver. This file contained two partitions, one being an LVM. I was able to setup the LVM-containing partition as a loopback device, run _lvm pvscan_ and then _lvm vgchange -ay_, and then mount the resulting volumes to copy over all the data contained within. (The second article explains how to do this.)<br>
