http://bugzilla.suse.com/show_bug.cgi?id=960118 http://bugzilla.suse.com/show_bug.cgi?id=960118#c5 --- Comment #5 from Roger Zhou <zzhou@suse.com> --- Further more testing, the problem scenario is true when the redundant link of DC is down, and then the other node couldn't re-join back. That said, there are chance to put this two-node cluster under risk, and this bug need be fixed. The frequency to reproduce this problem is different for the different operation. Reproduce Approach 1, 50% chance, by # systemctl stop pacemaker # systemctl start pacemaker Reproduce Approach 2, <20% chance, by # reboot Reproduce Approach 3, <10 chance, by # systemctl restart pacemaker -- You are receiving this mail because: You are on the CC list for the bug.
