How reproducible:
Every time

Steps to Reproduce:
1. Configure a system with CEPH RBD mirroring
2. Upload an image
3. Create a none replicated volume from an image - works.
# openstack volume create NoneReplVolFromImage --size 2 --image 06ea4aa6-4391-40fa-9f19-01fd0534cbe7

4. Create a replicated volume from an image - status error.
# openstack volume create ReplVolFromImage --size 2 --type REPL --image 06ea4aa6-4391-40fa-9f19-01fd0534cbe7

5. An empty replicated volume is created successfully, basic replication works.

6. Cinder list see error status on vol from #4
