Hi,
My test scenario is here;
(1) There are 4 nodes, and Heartbeat is running on the each node.
(2) unplugged the interconnect LANs from the all nodes.
-> split brain comes.
Each node would be isolated.
(3) plugged the LANs.
-> Heartbeat tries to recover from split brain
At this time, some nodes are NACK'd and that node would be shut down.
The log size is large, I create the new bugzilla entry.
http://developerbugs.linux-foundation.org/show_bug.cgi?id=1990
Heartbeat releases its all of the cluster member when it recovers a split
brain.
In this case, there are 4 DC nodes during a split brain,
so it seems that DC election conflicts and some nodes can not share the
status when its recovering stage.
It might be a bug of ccm.
Can I get any obvious evidences why the node is shut down from log?
Best Regards,
Junko Ikeda
