It's going to take me a bit of time to retest this with debugging info. This happened during a production change window I was given for this. I have the images backed up on another server for testing, but will take me a day or two. I'd appreciate it if you would open the bug to get us started and in front of some other people...

Come to think of it, considering it's a bug, how are other people resizing VMs with LVM partitions? Should I plan to find an alternate method to do this?
