Please re-paste the log files from that time period from both the victim and the surviving host, starting from the first log message in the same time period as the fence event, clear through to the surviving node has restored services. Also, please past your full cluster.conf file, and please only obfuscate passwords only. Likewise, please paste your full network configuration. With that said; You're probably facing transient network issues. Are there any logs in your switches around the same time period? Is multicast working properly? Is STP enabled and perhaps causing a temporary block in network traffic? The cluster certainly doesn't break randomly, there has to be a cause. :) -- Digimer E-Mail: digimer@xxxxxxxxxxx Freenode handle: digimer Papers and Projects: http://alteeve.com Node Assassin: http://nodeassassin.org "omg my singularity battery is dead again. stupid hawking radiation." - epitron -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
