Thanks for the explanations Lars, Any documentation on boothd usage with pacemaker on 1:1 fail-over scenario, and/or external/sbd usage with pacemaker will help us a lot.

That is true, but it will still participate in the corosync protocol (meaning an instability of the quorum node could translate to instability of your cluster); and if you really run pacemaker there, you'll have to keep it updated as well so that it doesn't become the eternal DC. A third node makes perfect sense if you need a third node in your cluster for redundancy and load reasons. It's not good to add one at this layer if all you need is better quorum. > For other approaches, I only know boothd. And what I know is it is suitable > for geo-redundancy purposes. I will look for fence_sanlock. boothd can also be used as a 1:1 fail-over scenario. Admittedly, it's overkill and makes the configuration more complex. I'd probably go with external/sbd, but then, I wrote that ;-) Regards, Lars -- Architect Storage/HA SUSE LINUX Products GmbH, GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer, HRB 21284 (AG Nürnberg) "Experience is the name everyone gives to their mistakes." -- Oscar Wilde _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
