    Description

      Hi,
      I have a question about a Primary node Rollback on a Replica Set.
      The documentation says:
      http://docs.mongodb.org/manual/core/replication/#replica-set-failover
      "Rollbacks occur when a primary accepts writes that other members of the set do not successfully replicate before the primary steps down."

      The question is:
      What does "other members" exactly mean?:

      • ALL other members need to replicate
      • even ONE member (lets call it S1) successfully replicates, and this is enough that Rollback does not occur, the data delivered to S1 will be delivered to other Secondaries.

      Would you please also clarify this in the documentation.

      If you have a detailed information/documentation about this behaviour, please just let me know.

      Thanks,
      Edouard
