This patch updates how cinder calculates it's free capacity. The new calculations are based off of the queens cinder specs that describes each of the capacity factors here: https://specs.openstack.org/openstack/cinder-specs/specs/queens/provisioning-improvements.html This patch updates the capacity filter to use the new capacity factors calculations, which is also used by the capacity weigher. The new calculate_capacity_factors describes each of the factors and returns a dictionary of each of the factors as calculated. Change-Id: Ic1b5737281e542d2782089a369e4b7941fc3d921

|
virtual free storage. Now both the Capacity Filter and the Capacity
|
|
Weigher use the same mechanism, which is based upon the defined terms in
