Hi people: I'm new in HA Clustering world. I started googling about HA clusters and I met heartbeat with 1.x configuration examples (using haresources). I made some tests and worked OK, then googling again and reading posts in this mailing list I read that 1.x configuration is deprecated so I should use 2.x configuration that includes CRM based on cib.xml config file.
Well I googled again and I found that heartbeat 2.1.4 was that lastest version that included the CRM because that code is developed now by the Pacemaker project. OK, I googled again and started to make some test based on the "Pacemaker configuration explained (February 2009 edition)" found at clusterlabs.org and I'm having some troubles when adding some resources (I will post asking for help about this later)... While googling (again) for solutions I read that SLES 11 it was recently released with HAE product. HAE now includes OpenAIS in replacement of Heartbeat. I googled again and found this: https://lists.linux-foundation.org/pipermail/openais/2007-December/009506.html I'm not an expert in clustering so I'm a little confused.I know that Pacemaker develops the core of the Cluster: The CRM ¿right?, but I read that pacemaker includes support for Heartbeat and OpenAIS (they're choices right?). So my questions are: - What's exactly OpenAIS? I don't understand the information found in its website - How is OpenAIS related to Heartbeat and Pacemaker? - OpenAIS is a total replacement for Heartbeat? If yes, which of those is better or has a better future? - If the previous if yes... so Will we need to abandon heartbeat knowledge and learn OpenAIS? Will we need to move from this mailing list to OpenAIS mailing list? :P I hope someone can give me some basic explanation about these 3 components because I'm confused and a little worried about the Novell decision to drop hearbeat for using OpenAIS. So I would like to be sure to start learning (and googling again) a HA Cluster solution that will the better and best maintained. Thanks ha users, and sorry if my english sucks P.D.: Red Hat doesn't include Heartbeat in its software media, but OpenAIS does? I read something like that in an article _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
