Hi
OK I have given this a try, and this does not work :
in fact, it returns : <other_name> not know in cluster.conf
or something likewise.
Knowing that, I have tried another thing :
set a name on eth1 in /etc/hosts such as :
10.0.0.2  nodehb #for heart beat
where is eth0 remains :
10.0.0.1  node (which also is the hostname)
Then in cluster.conf, I have changed all "name" values
from "node" to "nodehb"
And this seems to work : I mean the Heart-beat
frames are effectively running through eth1 now
and I have tried to failover by doing ifdown eth1 on
the first node and the failover has been successful.

So it seems that the Heart-Beat is not linked
to the IF linked to the hostname, but really linked
only to the names we put in cluster.conf.

Could someone confirm that point ?
And eventually tell me which eventual drawback I could
face to adopt this configuration ?

Thanks a lot
