Thanks for clarifying Akhilesh. That was not clear from the blog link above, which says that any blocks in a deleted snapshot born after the most recent snapshot will be freed. I do not see how that works for clones of snapshots. Are the details of clone deletion covered anywhere, or did I just not read the blog closely enough?
