Doc Text:
.Cloned images can be created from non-primary images Creating cloned child RBD images from mirrored non-primary parent image is now supported. Previously, cloning of mirrored images was only supported for primary images. When cloning golden images for virtual machines, this restriction prevented the creation of new cloned images from the golden non-primary image. This update removes this restriction, and cloned images can be created from non-primary mirrored images.

Description Sean Cohen 2017-01-11 20:01:38 UTC
In the case of OpenStack Glance, this capability would allow the creation of volumes from a DRed non-primary copy of an image. Proper support would most likely require implementing a deletion "recycling bin" to fix the corner cases with parent/child links and propagating of deletions (i.e. the clone of the non-primary parent image might not be mirrored and the primary parent image would not know about the child on the non-primary side. the primary image could be deleted but that deletion would not properly propagate since the non-primary image would have a child).
