[Linux-cluster] Manual multicasting address for CMAN bug

[Matthew Painter]

Hi Robert,

Thanks for your suggestion. I had tried this, and it gave an error when
starting cman due to incorrect configuration - turns out it is a 5.x option,
not needed for 6.x because it works out the interface based on the cluster
ip address.

Thanks anyway :)



You might try to add the multicast stanza inside the <clusternode> stanza as
well.  You can specify an specific interface as well.

For example,
                <clusternode name="node1.company.com" nodeid="1" votes="1">
                        <fence>
                                <method name="1">
                                        <device name="iLO_node1"/>
                                </method>
                        </fence>
                        <multicast addr="239.192.15.224" interface="bond1"/>
                </clusternode>

I have gotten this to work internally, but your environment may be
different.

Robert
