Comment 9 for bug 1539648

Problem with resize "small" -> "tiny" is present only without ceph.
If to use Ceph:
- Ceph RBD for volumes (Cinder)
- Ceph RadosGW for objects (Swift API)
- Ceph RBD for ephemeral volumes (Nova)
- Ceph RBD for images (Glance)
resize "small" -> "tiny" works fine.

Steps to reproduce:
- Deploy openstack without cepth
- Login as admin
- Launch instance with flavor tiny
- Resize it to flavor small
- Resize it to flavor tiny

Expected result:
- Instance will be resized to tiny, or there will be alert, that can't resize down (dependent of backend logic)

Actual result:
- Nothing happens, instance has still small flavor. There is notification that resize is scheduled only.
