[Pacemaker] Stonith / Fencing
Hi there, I'm working on stonith on my test cluster. It has, to me, a strange behaviour: when the condition to fence the other node happens, is it normal that both primary/secondary node fences the other one? I thought that the primary should fence the secondary, as it is the master at drbd level...but really the behaviour is different: sometimes is the master to kill the secondary, and sometimes is the secondary to kill the mastereven if I specified in the configuration, that the stonith primitive has to run only on the master node.
