Hi,

I'm looking for a way to add the property volume_backend_name to an existing Volume Type which is in use.

If I try to change this, I got the following error:

root@control01rt:~# openstack volume type show test-type

Failed to set volume type property: Volume Type is currently in use. (HTTP 400) (Request-ID: req-2b8f3829-5c16-42c3-ac57-01199688bd58)

Command Failed: One or more of the operations failed

Problem what I see is, that there are instances/volumes which use this volume type.

Have anybody an idea, how I can add the volume_backend_name property to the existing Volume Type?

thanks in advance!
