History

#14032 implementation should satisfy this one

#2 Updated by Samuel Just over 4 years ago

Actually, it doesn't. http://tracker.ceph.com/issues/14032 covers the primary making a decision about which log is authoritative. During activation, the peers receive the authoritative log and need to atomically rollback/forward to last_update. We already do this with rollback, this feature would include extending that mechanism to cover rollforward as well.
