I've ment to explore this connection for long, but never found much useful material on the subject. How does DLM fencing fit into the modern Pacemaker architecture? Fencing is a confusing topic in itself already (fence_legacy, fence_pcmk, stonith, stonithd, stonith_admin), then dlm_controld can use dlm_stonith to proxy fencing requests to Pacemaker, and it becomes hopeless... :) I'd be grateful for a pointer to a good overview document, or a quick sketch if you can spare the time. To invoke some concrete questions: When does DLM fence a node? Is it necessary only when there's no resource manager running on the cluster? Does it matter whether dlm_controld is run as a standalone daemon or as a controld resource? Wouldn't Pacemaker fence a failing node itself all the same? Or is dlm_stonith for the case when only the stonithd component of Pacemaker is active somehow? -- Thanks, Feri. _______________________________________________ Users mailing list: Users@clusterlabs.org http://clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
