yes, Heartbeat is the CCM (cluster consensus and membership) layer and Pacemaker relies on it to get valid information about node health and uses it to transfer messages/updates to the other nodes. use "crm_mon -1fr" to see the current state of your cluster resources you already?? configured in Pacemaker. if you use IPaddr2 RA you have to use "ip addr show" to see the virtual IPs. there are a lot of howtos available, maybe you want to start at: http://www.clusterlabs.org/wiki/Documentation#Examples Regards, Andreas -- Need help with Pacemaker? http://www.hastexo.com/now > > > Thank's Niclas > > > > P.S. : A user have send me a mail that with the mail client i send the > question before made a mistake with my FORM Field, hopefully now away! > > _______________________________________________ > Linux-HA mailing list > [email protected] > http://lists.linux-ha.org/mailman/listinfo/linux-ha > See also: http://linux-ha.org/ReportingProblems
