The pithy ruminations from "Alvaro Jose Fernandez" on
<Re: [Linux-cluster] clusternode name and uname -n> were:
=>
=> Hadn't to...for example look at the scenario where there is a separation
=> between the heartbeat/fencing network, and the application/public
=> network.
Yes, that is exactly my experience as well.
=>
=> In this case it's seems logical to me that clusternode name should point
=> to private names (ie, call them "nodexxx-hb" or "nodexxx-private" , etc.
That is exactly what I am doing.
In our case $hostname is the public interfac, "${hostname}-admin" is
the administrative network, "${hostname}-drac" is the DRAC interface.
We use "${hostname}-admin" for RHCS communication:
# hostname
acme-infrastructure1.fqdn
# clustat
Cluster Status for acme-infra @ Thu Apr 28 11:08:42 2011
Member Status: Quorate
Member Name ID Status
------ ---- ---- ------
acme-infrastructure2-admin 1 Online, rgmanager
acme-infrastructure1-admin 2 Online, Local, rgmanager
acme-infrastructure3-admin 3 Online, rgmanager
I vaguely recall having to play some games with host ordering in /etc/hosts
when setting up the cluster.
Thanks,
