Description Eric Harney 2018-04-27 16:07:18 UTC
+++ This bug was initially created as a clone of Bug #1563565 +++

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.
