[Pacemaker] [pacemaker] need some help regarding network failure setup in pacemaker.
Hello Everybody How can we detect network failure in pacemaker configuration. where my to nodes in cluster frame work are as follows two network routers connected via switch as mediator for communication. how can we detect network failure and stop the heartbeat processes, when i shutdown the interface. i am seeing a split brain issue.where heart beat is started on two nodes and each acting as two different heartbeat process. I had configured pingd resource which comes with pacemaker, as clone processes when there is a network failure, i see there is a split brain issue where the heart beat processes are starting separately on both nodes, my question is here is, is there any way to stop the heart beat process while pingd on a particular node gives that there is communication between the interface and node where HA is running.
