Description of problem: When I try to live migrate (retype) an attached encrypted volume from a netapp(iscsi) backend to Ceph backend, migration doesn't do anything volume remains on netapp backend, no notification\warning on cli.
Version-Release number of selected component (if applicable):
puppet-cinder-15.4.1-1.20200831153423.el8ost.noarch
openstack-cinder-15.3.1-5.el8ost.noarch
python3-cinder-15.3.1-5.el8ost.noarch
python3-cinderclient-5.0.1-1.20200326150227.8fa0882.el8ost.noarch
How reproducible:
I suspect every time
Steps to Reproduce:
1. Create both types/backend:
(overcloud) [stack@undercloud-0 ~]$ cinder type-create encnetapp

(overcloud) [stack@undercloud-0 ~]$ cinder encryption-type-create --cipher aes-xts-plain64 --key_size 256 --control_location front-end encnetapp nova.volume.encryptors.luks.LuksEncryptor

----------------------------------------------------------------------------------------------------------------------
(overcloud) [stack@undercloud-0 ~]$ cinder service-list

(overcloud) [stack@undercloud-0 ~]$ cinder type-key encnetapp set volume_backend_name=tripleo_netapp2
2. Create an encrypted netapp backed volume:
(overcloud) [stack@undercloud-0 ~]$ cinder create 1 --name encnetappvol1 --volume-type encnetapp

3. Attach volume to instance:
(overcloud) [stack@undercloud-0 ~]$ nova volume-attach 7137e3a2-9745-4457-bbf4-60cc3c07fb92 9426bce0-889f-4319-a6b6-c5347351d108

(overcloud) [stack@undercloud-0 ~]$ cinder list
-----------------------------------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------+-------------------------------------
| 9426bce0-889f-4319-a6b6-c5347351d108 | in-use | encnetappvol1 | 1 | encnetapp | false | 7137e3a2-9745-4457-bbf4-60cc3c07fb92 |
4. Issue the retype command:
(overcloud) [stack@undercloud-0 ~]$ cinder retype 9426bce0-889f-4319-a6b6-c5347351d108 ceph --migration-policy on-demand
Notice no error or warning.
5. Volume remains on source/netapp backend:
(overcloud) [stack@undercloud-0 ~]$ cinder list
-----------------------------------------------------------------------------------------------------------------------
| ID | Status | Name | Size | Volume Type | Bootable | Attached to |
-----------------------------------------------------------------------------------------------------------------------
| 9426bce0-889f-4319-a6b6-c5347351d108 | in-use | encnetappvol1 | 1 | encnetapp | false | 7137e3a2-9745-4457-bbf4-60cc3c07fb92 |
Actual results:
Volume doesn't migrate.
Expected results:
if supported, volume should migrate,
else we should block/warn user of trying this.
