Hi Chrissie,
Are you pointing me to the paragraph "what's the right way to ....eth0 ?"
I've tried this at first adding adding a suffix to the interfaces but nothing happened. Suffix -p may be hardcoded (I've used -hb)
Here's an outputof my /etc/hosts (identical on both nodes):
10.146.15.184 node1 node1.mydomain
10.146.15.175 node2 node2.mydomain
192.168.84.50 node1-hb
192.168.84.51 node2-hb
10.146.15.175 node2 node2.mydomain
192.168.84.50 node1-hb
192.168.84.51 node2-hb
Still using bond0 ....

Hi,
I'm trying to send cluster communications thru dedicated LAN interfaces
(out of band network) separate from the production interfaces but it
doesn't seem to be functional.
I have a 2 nodes cluster (RHEL 5.3) with 2 bonding interfaces each, one
bonding for production on a given Vlan and the other on a dedicated and
isolated LAN (out of band LAN).
According to some cman doc (that may be outdated), the way to do so is
to declare explicitely at each clusternode level the multicast addr of
the cluster and the interface on which the coms are sent.
<clusternode name="node1.mydomain" nodeid="1" votes="1">
<multicast addr="239.128.2.1" interface="bond1"/>
</clusternode>
<clusternode name="node2.mydomain" nodeid="2" votes="1">
<multicast addr="239.128.2.1" interface="bond1"/>
</clusternode>
and the cman multicast addr:
<cman expected_votes="3" two_node="0">
<multicast addr="239.128.2.1"/>
</cman>
(I have a qdiskd).
After restarting the cluster, traffic is still sent through bond0 which
is the production interface.(tcpdump -i bond0 host 239.128.2.1)
The wiki has a up-to-date item on how to assigned different ethernet interfaces for cman:
