Description of problem: When a cinder volume is created the ontap backend fits the LUN to the best geometry. It makes the image uploaded from a volume larger than expected and a volume of larger size must be created from that image. Using the use-exact-size parameter the backend does not fit to best geometry, the image uploaded from that volume has the same size and a volume of the same size may be created from that image. Upstream bug is fixed, any plan to merge this to RHOSP?
