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?

Thanks,
Alex
