[Linux-cluster] Cannot connect to rgmanager

[Maxwell, Jamison [HDS]]

I am attempting to create a two node cluster where the only resource required would be a shared IP address, however, after a couple of attempts I continue to fail.  I have followed a guide located at http://www.openlogic.com/wazi/bid/188071/ .  Everything appears to work fine until I get to the point where I actually add the IP address resource, both cluster nodes appear as online and quorate and the configuration validates, but will not enable the new resource.  Below I am including any information that I think may be relevant, but feel free to ask for more.

===========================================
[root@ hostname]# cat /etc/cluster/cluster.conf
<?xml version="1.0"?>
<cluster config_version="4" name="hacluster">
        <cman expected_votes="1" two_node="1"/>
        <clusternodes>

                        <fence>
                                <method name="single"/>
                        </fence>
                </clusternode>
                <clusternode name=" actual name of node " nodeid="2" votes="1">
                        <fence>
                                <method name="single"/>
                        </fence>
                </clusternode>
        </clusternodes>
        <fencedevices/>
        <rm>
                <failoverdomains/>
                <resources/>
                <service autostart="1" exclusive="0" name="IP" recovery="relocate">
                        <ip address="actual shared IP address" monitor_link="on" sleeptime="10"/>
                </service>
        </rm>
</cluster>
===========================================

[root@ hostname]# clusvcadm -e IP
Local machine trying to enable service:IP...Could not connect to resource group manager
===========================================

[root@ hostname]# strace clusvcadm -e IP

connect(5, {sa_family=AF_FILE, path="/var/run/cluster/rgmanager.sk"}, 110) = -1 ENOENT (No such file or directory)
close(5)                                = 0
write(1, "Could not connect to resource gr"..., 44Could not connect to resource group manager
) = 44
exit_group(1)                           = ?
===========================================

I would most like to call your attention to the line "write(1, " connect(5, {sa_family=AF_FILE, path="/var/run/cluster/rgmanager.sk"}, 110) = -1 ENOENT (No such file or directory)".  There was also a someone who mailed this list with what appears to be the same problem, however, no issue is present in the conversation.  The topic is located here: http://www.redhat.com/archives/linux-cluster/2012-August/msg00156.html .

This is version 6.3, no iptables and no selinux until I can get this working.  I greatly appreciate any assistance that can be offered.
