It's here simply to ease the most boring (i.e., automatization-friendly) part. I would suggest using the version available in RHEL 6.7 release (as of few days back) if possible, or the latest version packaged in Fedora.

Is > there a tool or something to port the configuration to the cib? > > Michelle Streeter Hi Michelle, A couple of things; First, please use 1.1.12 that ships with RHEL/CentOS 6.6. There is a pretty significant change from cman/rgmanager to pacemaker, and the cluster.conf doesn't map 1:1. That said, Jan Pokorný from Red Hat has been working on a project called 'clufter' that aims to assist this transition: https://github.com/jnpkrn/clufter If you are relatively new to clustering, this might help provide some clarity on why things changed: https://alteeve.ca/w/History_of_HA_Clustering If I might suggest, with RHEL 7.1 starting to firm up and given that pacemaker on RHEL 6 requires the cman plugin (RHEL 7 does not), and given that you'll want time to learn and understand all this, you might want to try a fresh build on RHEL 7 with pacemaker 1.1.12 and corosync v2, which changed a lot from the v1 days (it became the quorum provider, among other things). If you don't have a pressing need to move from rgmanager to pacemaker, I'd leave the RHEL 6 + cman + rgmanager cluster alone and focus my time on learning a fresh build. You can then use the production rgmanager configuration as your template to reproduce in pacemaker. In any case, we're here to help so please ask. The #clusterlabs IRC channel is fairly active as well, though folks span many timezones, so if you ask a question and no one answers, please hang around. Folks are good about reading/replying when they come online.

[ClusterLabs] Cluster.conf to cib.xml
The previous administrator setup our cluster using the cman version and the cluster.conf file. I we want to upgrade to pacemaker 1.9 on our rhel 6.6 and so I have been testing this upgrade. But I noticed that the cib.xml does not reflect what we have in the cluster.conf file. Is there a tool or something to port the configuration to the cib?
