I have configured the cluster in the lab ( with three nodes) and set the
broadcast. Here is the configuration --
<?xml version="1.0"?>
<cluster alias="test" config_version="61" name="test">
<fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="3"/>
<clusternodes>
<clusternode name="node1" nodeid="1" votes="1">
<fence>
<method name="1">
<device name="ilo-node1"/>
</method>
</fence>
</clusternode>
<clusternode name="node2" nodeid="2" votes="1">
<fence>
<method name="1">
<device name="ilo-node2"/>
</method>
</fence>
</clusternode>
<clusternode name="node3" nodeid="3" votes="1">
<fence>
<method name="1">
<device name="ilo-node3"/>
</method>
</fence>
</clusternode>
</clusternodes>
#---------------------------------------
<cman>
<totem broadcast="yes" ip="192.168.205.255"/>
</cman>
#---------------------------------------
<fencedevices>
<fencedevice agent="fence_ilo" hostname="node1r" login="Admin" name="ilo-node1r" passwd="xxx"/>
<fencedevice agent="fence_ilo" hostname="node2r" login="Admin" name="ilo-node2r" passwd="xxx"/>
<fencedevice agent="fence_ilo" hostname="node3r" login="Admin" name="ilo-node3r" passwd="xxx"/>
</fencedevices>
<rm>
<failoverdomains/>
<resources/>
</rm>
<dlm plock_ownership="1" plock_rate_limit="0"/>
<gfs_controld plock_rate_limit="0"/>
</cluster>
When I am executeing the cman_tool status command , getting the following output
[root ~]# cman_tool status
Version: 6.2.0
Config Version: 61
Cluster Name: test
Cluster Id: 25790
Cluster Member: Yes
Cluster Generation: 968
Membership state: Cluster-Member
Nodes: 3
Expected votes: 3
Total votes: 3
Quorum: 2
Active subsystems: 7
Flags: Dirty
Ports Bound: 0
Node name: node1
Node ID: 1
Multicast addresses: 239.192.xxx.xx
Node addresses: 192.168.205.1
Would you pl. confirm the broadcast configuration!!
Again ,in the following document
https://access.redhat.com/kb/docs/DOC-40821
under Unsopported items/ Netowrking, it is telling that broadcast is not supportive...
Thanks and regards.
