Hi: I am testing ceph-mon brain split . I have read the code . If I understand it right , I know it won't be brain split. But I think there is still another problem. My ceph version is 0.94.10. And here is my test detail : 3 ceph-mons , there ranks are 0, 1, 2 respectively.I stop the rank 1 mon , and use iptables to block the communication between mon 0 and mon 1. When the cluster is stable, start mon.1 . I found the 3 monitors will all can not work well. They are all trying to call new leader election . This means the cluster can't work anymore. Here is my analysis. Because mon will always respond to leader election message, so , in my test, communication between mon.0 and mon.1 is blocked , so mon.1 will always try to be leader, because it will always see mon.2, and it should win over mon.2. Mon.0 should always win over mon.2. But mon.2 will always responsd to the election message issued by mon.1, so this loop will never end. Am I right ? This should be a problem? Or is it was just designed like this , and should be handled by human ? -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
