Malik, Have you created 'mystoragetype' with 'openstack volume type create' ? If not, I believe the backup behavior is to use __DEFAULT__ . https://docs.openstack.org/cinder/latest/admin/blockstorage-volume-number-weigher.html#volume-type You will need to restart Cinder after creating the volume type and updating cinder.conf. Hope this helps. Jay On 2/18/2021 5:05 AM, Malik Obaid wrote: > > Hi, > > I am creating nova instance with cinder backed iscsi storage. I have > created multiple storage types.
