Hi Don't remember in details, it was at the end of 2010 ... but : Why pacemaker is fencing a node ? because it was one of my simple HA test : for example, make the heartbeat no more working so that pacemaker fences the node, and it did it for sure, but on the remaining node, sometimes ocfs2 crashes the node, or the FS ocfs2 was passing in read-only ... I did simple HA tests, such as this one above, to check the robustness of the configuration and many times, it failed and make the HA cluster down. That's why I ask for status today.

I'd start inspecting the logs: Why is pacemaker fencing a node? Why is the filesytem read-only?
