Hello!
i've got 5-node cluster with ubuntu 14.04+OS Liberty.
All instances run on lvm volumes (raw images, as far as i understand it)

Is it possible to resize (and, possibly, migrate) lvm-backed nova instances? I mean changing cpu\memory\disk size When I try to do nova resize, I am getting an error

Instance rollback performed due to: Migration pre-check error: Migration is not supported for LVM backed instances

What's the workaround? Yes, I can go into DB manually every time, but that's not a good looking solution, especially for a newly created flavors
