Hi Vishal, I think that’s true, yes. The cluster has a leader (overseer), but this particular shard doesn’t seem to have a leader (yet). Logs should give you some pointers about why this happens (it may be, for example, that each replica is waiting for the other to become a leader, because each missed some updates).
