[ClusterLabs] Does CMAN Still Not Support Multipe CoroSync Rings?

[Eric Robinson]

Well, I finally got around to trying out the <altname> tag and I managed to get two rings running, but the first ring is not obeying my address and port directives.

Here's my cluster.conf

<cluster config_version="9" name="ha10ab">
  <fence_daemon/>
  <clusternodes>
    <clusternode name="ha10a" nodeid="1">
      <multicast addr="239.255.5.1" port="4000"/>
      <altname name="ha10a-cl" port="4000" mcast="239.255.5.2"/>
      <fence>
        <method name="pcmk-method">
          <device name="pcmk-redirect" port="ha10a"/>
        </method>
      </fence>
    </clusternode>
    <clusternode name="ha10b" nodeid="2">
      <multicast addr="239.255.5.1" port="4000"/>
      <altname name="ha10b-cl" port="4000" mcast="239.255.5.2"/>
      <fence>
        <method name="pcmk-method">
          <device name="pcmk-redirect" port="ha10b"/>
        </method>
      </fence>
    </clusternode>
  </clusternodes>
  <cman broadcast="no" expected_votes="1" transport="udp" two_node="1"/>
  <fencedevices>
    <fencedevice agent="fence_pcmk" name="pcmk-redirect"/>
  </fencedevices>
  <rm>
    <failoverdomains/>
    <resources/>
  </rm>
</cluster>

The rings are up...

[root at ha10b ~]# corosync-cfgtool -s
Printing ring status.
Local node ID 2
RING ID 0
        id      = 192.168.10.61
        status  = ring 0 active with no faults
RING ID 1
        id      = 198.51.100.61
        status  = ring 1 active with no faults

HOWEVER, when I run tcpdump, I can see that ring2 running on the appropriate multicast address and port, but ring1 is running on the default address and port...

[root at ha10b ~]# tcpdump -nn -i bond0 net 239.192.0.0/16
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on bond0, link-type EN10MB (Ethernet), capture size 65535 bytes
22:54:36.738395 IP 192.168.10.60.5404 > 239.192.170.111.5405: UDP, length 119
22:54:40.547048 IP 192.168.10.60.5404 > 239.192.170.111.5405: UDP, length 119

How do I get ring1 running on my desired address and port of 239.255.5.1, port 4000
