HNAS NFS driver allows the creation of cloned volumes using volume types that are not the same as the ones from the source volume. This could make cinder information inconsistent with the real volume location in the backend when we have multiple pools configured. As the clones are always created in the same pool as the source volumes, this patch makes the driver accept the creation of cloned volumes only if they have the same volume type as the source volume. Closes-Bug: #1660411 Change-Id: I1272a6d27d7f172e77f1260a2acc6fc7c02e2e73
