Openstack release is Liberty
Backend is Ceph release infernalis

Failed to migrate volume"
>From command line it creates a new volume instead of migrating it and error
>reported is Remote error: ImageExists error renaming image
cinder --debug migrate da3ab25b-46c4-41bd-ba57-67c8e481c8fc ostackn3@rbd#RBD
