Hi everybody, Recently I have configured DRBD+Pacemaker+Corosync cluster using LVM. All works fine. Now I'm working in discovering and fixing possible issues. I have caused a SPLIT BRAIN (Crossover ethernet cable disconnected). I have read about typical operations that I have to follow to solve it: Choosing a victim, making secondary all and then making in the other node, primary all. In some cases the cluster, after split brain problem, has not master node so, both nodes appears in crm_mon as slave but with ip resource started. In other cases, after split brain, Corosync solves automatically the SPLIT BRAIN and discards the data from a node (I don't know what is the algorithm to choose a victim automatically) and make primary the other node. Anybody could tell me if this is normal behaviour? I have to optimize my configuration to get something ... And another question ... in a environment with two servers, with two ethernets and one of them as crossover link between nodes. What would the most typical problems that could happen? Thanks in advance. Regards, Antonio. -------------- next part -------------- An HTML attachment was scrubbed...
