Merged in upstream stable/grizzly for 2013.1.3. Note that this is currently only fixed in that you will not get LVs created outside of the pool. Volume clone from snapshot for the ThinLVM driver will still fail. This is being followed up on in bug 995766 which requires another patch. Needs to be documented as known issue for 3.0.z unless that bug also gets fixed and backported to the same release. verified using openstack-cinder-2013.1.3-2.el6ost Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: by going trough the sequence: > origin (vol1) -> snapshot (snap1) -> create from snapshot (vol2) vol2 gets allocated within the VG but outside the POOL Version-Release number of selected component (if applicable): openstack-cinder-2013.1.2-3.el6ost.noarch Steps to Reproduce: 1. configure cinder with the ThinLVM driver 2. create a volume origin (v1) 3. create a snapshot of "v1" (s1) 4. create a volume based on "s1" (v2) Expected results: v2 should be placed within the VG POOL, as it happens for v1 and s1
