Description Harald Klein 2016-12-02 08:51:18 UTC 
Description of problem:

Given a clone with a single protected snapshot, flatten the parent to dissociate the HEAD revision from the parent image. If you attempt to remove the protected snapshot, the first step will dissociate the snapshot from the parent image but later the operation will fail due to the snapshot being protected. This leaves the snapshot no longer associated with the parent image and will permit the parent image's snapshot to be unprotected and deleted. 

Version-Release number of selected component (if applicable):

Ceph 1.3 (Hammer)

Expected results:

The protected status should be verified first before altering the image.
