Heartbeat is deprecated. It's not been developed in some time (though Linbit supports existing installs). You have two options here; 1. Red Hat Cluster Suite (corosync + cman + rgmanager) 2. Pacemaker (corosync + pacemaker) There are pros and cons to both, and you need to choose which is best for you. 1. Is the only* officially supported (by Red Hat) HA stack. This means that, through the life of RHEL (and thus CentOS), upgrades to the OS will never break your cluster. 2. Pacemaker is the future of HA clustering. It is expected that, in RHEL 7, Pacemaker will replace RHCS. So there is a strong argument to start with pacemaker now. The main problem that might push you away from Pacemaker (and what keeps me personally on RHCS) is that Pacemaker is in "Tech Preview" mode in RHEL. What this means is two fold; a) The pacemaker package does not get updated except with y-stream releases (6.0 -> 6.1 -> 6.2 -> etc). Even if bugs are found between releases, no updated package will be shipped. b) Each update to the 'pacemaker' package may or may not be compatible with previous releases. For example, the update from 6.3 to 6.4 caused compatibility problems. Many people run production pacemaker clusters, but you need to take your time to learn how it works. You will also want to make sure that you test updates before applying them to production machines. *Personally*, I stick to rhcs. That said, the more people who use pacemaker, the better it will get. It's really up to you. Hope this helps shed light. digimer * There are rumours that certain specific configurations of pacemaker can be supported by Red Hat. -- Digimer Papers and Projects: https://alteeve.ca/w/ What if the cure for cancer is trapped in the mind of a person without access to education? _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
