<div dir="ltr">Hi everybody,<br><br>Recently I have configured DRBD+Pacemaker+Corosync cluster using LVM. All works fine. <br>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. <br>
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. <br>
<br>Anybody could tell me if this is normal behaviour? I have to optimize my configuration to get something ... <br>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?<br>
<br>Thanks in advance. <br><br>Regards, <br><br>Antonio.</div>
