Description of problem:

    [shift-on-stack] Cinder CSI driver is not able to create pvcs from volume snapshots when there are multiple (matching) volume and compute AZs:
"Failed to CreateVolume: Expected HTTP response code [202] when accessing [POST https://overcloud.redhat.local:13776/v3/668259885d1d4e538fb1f071f52a6309/volumes], but got 400 instead:
{"badRequest": {"code": 400, "message": "Invalid input received: Volume must be in the same availability zone as the snapshot"}}"

Version-Release number of selected component (if applicable):
