So I think that's a good to implement a similar feature in rbd, as attached(rbd_snap_tree.jpeg). But, is that a hot requirement for us? as Jason mentioned, A rollback is a pretty large sledgehammer (i.e. not efficient) approach to switch between a hierarchy of historical configurations. Maybe clone is much better. If so, the hierarchy of snapshots is not a "tree", but a "line". Therefore, I am here to collect more opinions on this topic. What do you think about this feature? BTW, Jason provide another idea, show a tree view about the relationship between parents and children. Yea, that's another idea, but I think that's good. what do you think about this one? Thanx Dongsheng
