Description Cyril Lopez 2021-04-20 09:02:26 UTC

NetApp ONTAP Cinder driver has support for setting QoS.
When a Cinder volume is created with a volume-type associated to a QoS entity, the driver creates a QoS policy group at the ONTAP back end, and associates it to the entity representing the Cinder volume (either a LUN or a file within an NFS share).
When a migrate operation is issued, the QoS policy group is deleted.

Steps to reproduce:
- Set up 2 ONTAP back ends `ontap1` and `ontap2`
- Create a Cinder QoS `qos_test`
- Create a Cinder volume type `ontap`
- Associate the QoS `qos_test` to the volume type `ontap`
- Create a Cinder volume with the volume type `ontap`
- Migrate the volume to another ONTAP back end
- Wait for the driver to perform a host-assited migration
- Wait for the driver to create a new QoS policy group and associate it to the new LUN/file representing the volume

Expected result:
- Have the new QoS policy group associated to the LUN/file permanently.

Actual result:
- The new QoS policy group is deleted afer a few minutes.
