2016-11-24 01:52:27 zhangdaolong summary RBD drivers create volume from volume when the config "rbd_max_clone_depth" changed. RBD drivers can't continue create to volume from volume when the config "rbd_max_clone_depth" changed.
2016-11-24 01:52:55 zhangdaolong description Reproduce the process： 1.config rbd_max_clone_depth #vim cinder.conf ---------------------- rbd_max_clone_depth=3 ---------------------- 2.create vol 3.create vol1 from vol 4.create vol1-1 from vol1 5.create vol1-1-1 from vol1-1 volume relationship: vol----->vol1----->vol1-1----->vol1-1-1 5.chang rbd_max_clone_depth from 3 to 1 # vim cinder.conf ----------------------- rbd_max_clone_depth=1 ----------------------- 6.create test from vol1-1-1 or vol1-1 Except results: The volume was created successfully In fact results: Failed to create volume
