Description of problem: A recent 16.1.4 Cinder RFE bz1888672, added the option to live migrate attached volume from ceph to none ceph, a second related RFE bz1888674 does vise versa Ceph to none Ceph. While verifying these two I had stumbled upon a Nova limitation, https://bugzilla.redhat.com/show_bug.cgi?id=1926761#c4 If I understand correctly migration(retype) of attached encrypted volumes, isn't supported due to Nova limitation. This needs to be documented, I'm not sure where if in general storage or with relation to the two new RFEs.
