Hi Doug,
I have some 2-node active-passive clusters that occasionally lose Corosync connectivity. The connectivity is fixed with a reboot. They don't have shared storage so stonith doesn't have to happen for another node to take control of the resource. Also they are VMs so I can't use a standard stonith method.
If you use virtual machines connected via a local bridge you could try to disable multicast snooping on your bridge to improve corosync connectivity. Similar to:
echo "0" > /sys/class/net/virbr0/bridge/multicast_snooping HTH, Sven _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
