Kaveh Vahedipour 1b75220a1b [3.4] Early sort out system collections for maintenance (#7589) 2018-12-10 15:16:35 +01:00
Lars Maier 4bf2302150 Do nothing in phaseTwo if leader has not been touched. (#7579)
* Do nothing in phaseTwo if leader has not been touched.

* Drop follower if it refuses to cooperate.

This is important since a dbserver that is follower for a shard will
after a reboot think that it is a leader, at least for a short amount
of time. If it came back quickly enough, the leader might not have
noticed that it was away.
