--- other: - | Steps are taken to minimize chances of confusion between the default block storage volume type established by the CinderDefaultVolumeType parameter, and cinder's own __DEFAULT__ volume type. In a new deployment where no volumes exist, cinder's __DEFAULT__ type is deleted because it is redundant. In an upgrade scenerio, if volumes exist then the __DEFAULT__ type's description is updated to indicate the actual default volume type is the one established by the CinderDefaultVolumeType parameter.
