    Description

      In DNE phase I, for cross-MDT operation, we only send updates to one MDT, which are executed on this MDT. for example create remote directory on MDT1, MDT0 will only send object create req to MDT1.

      Instead in DNE phase II, we will send all updates to other MDT for recovery purpose. In above example, MDT0 will send both object create and name insert to MDT1, and MDT1 will execute those updates which are belong to this MDT.
