Description Sofia Enriquez 2021-02-22 19:52:58 UTC 
Description of problem:
Cinder tries to migrate the volume in a generic way and it fails because it doesn't know how to handle RBD Objects.
A new implementation should be added to the RBD driver to handle this scenario and avoid using the generic driver
by default.

Version-Release number of selected component (if applicable):
RHOSP 13.0
RHOSP 16.0
RHOSP 16.1
RHOSP 16.2

How reproducible:
Always

Steps to Reproduce:

1. openstack volume type create --encryption-provider nova.volume.encryptors.luks.LuksEncryptor --encryption-cipher aes-xts-plain64 --encryption-key-size 256 --encryption-control-location front-end LuksEncryptor-Template-256
2. cinder create 1 --name encrypt-vol --volume-type LuksEncryptor-Template-256 
3. cinder retype encrypt-vol ceph --migration-policy on-demand

Actual results:
