Hi All,
I would really appreciate some guidance on migrate volume(storage-assisted 
volume migration).  I have a multi backend environment where each volume type 
has a volume_backend_name extra spec.  When I do a migrate to move my volume 
from one backend(host) to another it fails saying there are no hosts available. 
 On tracing the issue I see the volume_backend_name is the problem.  The value 
of volume_backend_name will always be different from source to target, but 
openstack blocks the operation from proceeding because of this difference.

>From the logs...

Thank you in advance
Helen
