[ClusterLabs] force RHEL6 and derivates to use corosync.conf

[Ionut Gogu]

Thanks for your answer Andrew,
i found very useful possibility to use corosync.conf for configuration of 2
redundant rings over 2 separate NICs, because i have the following
configuration:

*node01*
nic0 - productive network (82.77.xx.11 node01)
nic1 - corosync ring1     (10.1.1.11 node01hb0)
nic2 - corosync ring2     (10.1.2.11 node01hb1)
nic3 - backup network     (192.168.1.11 node01-back)

*node02*
nic0 - productive network (82.77.xx.12 node02)
nic1 - corosync ring1     (10.1.1.12 node02hb0)
nic2 - corosync ring2     (10.1.2.12 node02hb1)
nic3 - backup network        (192.168.1.12 node01-back)

I would like to use for <clusternode name> parameter, real hostnames of the
linux machines (node01 & node02) and 2 redundant rings over network
interfaces node01hb0 and node01hb0, but in RHEL6.5 6.6 only possibility
that i have founded to run 2 redundant rings over 2 different NICs is to
use for <clusternode name> parrameters: node01hb0 and node02hb0 in
combination with <altname> :

  <clusternodes>
    <clusternode name="node01hb0" nodeid="1">
      <altname mcast="226.10.1.1" name="node01hb1" port="5015"/>
    </clusternode>
    <clusternode name="node02hb0" nodeid="2">
        <altname mcast="226.10.1.1" name="node02hb1" port="5015"/>
    </clusternode>
  </clusternodes>

  <cman keyfile="/etc/cluster/corosync.key" expected_votes="1" two_node="1">
  <multicast addr="226.1.2.1" port="5010"/>
