A couple of things; First, please use 1.1.12 that ships with
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
If you are relatively new to clustering, this might help provide some
clarity on why things changed:
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.
