todo:

  1. remote snapshot need make sense of volume status on slave: when create snapshot, it only create snapshot meta on dr , no need to append snapshot journal entry

  2. snapshot control should enhance code robust, take volume status, replication status in consideration on master: can create local and remote snapshot on slave: should reject local snapshot
