Hi, Did you configure corosync ? Normally corosync starts pacemaker, which in turn starts the heartbeat deamons. But you have to configure the latter using for example a pcmk file with configuration in /etc/corosync/conf.d/ (from the top of my head). I normally use : http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Clusters_from_Scratch/ Regards, Michel On Wed, 2011-11-23 at 12:16 -0500, Hal Martin wrote: > Hello all, > > I am trying to create a corosync/pacemaker cluster using CentOS 6.0. > However, I'm having a great deal of difficulty doing so. > > Corosync has a valid configuration file and an authkey has been generated. > > When I run /etc/init.d/corosync I see that only corosync is started. > >From experience working with corosync/pacemaker before, I know that > this is not enough to have a functioning cluster.
