Bug Description
If run
openstack volume create --type fs7300_iscsi --bootable --image RHEL94 myvol_name --size 140
expected to see Flashcopy cloning triggered on the storage device. Instead, image is downloaded to one of the control plane nodes and then copied to the new volume over ISCSI. No cloning on the backend.
If I create volume from another volume then it triggers cloning just fine.
