Re: New user can't get cman to recognize other systems

Sure, and thanks for helping.

Here's the /etc/cluster/cluster.conf file and it is identical on all three
systems:

<cluster config_version="11" name="pgdb_cluster">
  <fence_daemon/>
  <clusternodes>
    <clusternode name="csgha1" nodeid="1">
      <fence>
        <method name="pcmk-redirect">
          <device name="pcmk" port="csgha1"/>
        </method>
      </fence>
    </clusternode>
    <clusternode name="csgha2" nodeid="2">
      <fence>
        <method name="pcmk-redirect">
          <device name="pcmk" port="csgha2"/>
        </method>
      </fence>
    </clusternode>
    <clusternode name="csgha3" nodeid="3">
      <fence>
        <method name="pcmk-redirect">
          <device name="pcmk" port="csgha3"/>
        </method>
      </fence>
    </clusternode>
  </clusternodes>
  <cman/>
  <fencedevices>
    <fencedevice agent="fence_pcmk" name="pcmk"/>
  </fencedevices>
  <rm>
    <failoverdomains/>
    <resources/>
  </rm>
</cluster>

uname -n reports "csgha1" on that system, "csgha2" on its system, and
"csgha3" on the last system.
I don't seem to have gethostip on any of these systems, so I don't know if
the next section helps or not.
"ifconfig -a" reports csgha1: eth0 = 172.17.1.21
                                         eth1 = 10.10.1.128
                            csgha2: eth0 = 10.10.1.129
Yeah, I know this looks a little weird, but it was the way our automated VM
control did the interfaces
                                         eth1 = 172.,17.1.3
                            csgha3: eth0 = 172.17.1.23
                                         eth1 = 10.10.1.130
The /etc/hosts file on each system only has the 10.10.1.0/24 address for
each system in in it.
iptables is not running on these systems.

Let me know if you need more information, and I very much appreciate your
assistance.
