Description Giulio Fidente 2021-12-13 11:22:10 UTC

Implement support for Ceph clone v2 in the RBD driver

This will permit deletion of images which still have COW clones created either by Cinder or Nova in different pools, deferring to Ceph management of the "trash" [1]. It is complementary to the corresponding Cinder feature [2]

Removing from the 18 backlog for now, we need to completely solve the cinder case before we start thinking about Glance. Will reassess target when the cinder implementation is done.
