Server configuration: 3 voters, 2 observers (attached). > 2. Bring up 2 voters and one observer. It's enough for quorum. > 3. Shut down the one from the quorum who is the follower. > As I understand, expected result is that leader will start a new election > round so that to regain quorum. > But the real situation is that it just says goodbye to that follower, and is > still operable. (When I'm shutting down 3rd one -- observer -- leader starts > trying to regain a quorum). > (Expectedly, if on step 3 we shut down the leader, not the follower, > remaining follower starta new leader election, as it should be). -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
