Re: [Linux-cluster] Use alternate network interfaces for heartbeat in RHCS



Ok,

It answers my last question.

I have been confused by some mention somewhere in a post or doc saying that cman has a built-in algorithm to determine, just by adding entries in /etc/hosts, the right interfaces to use .

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
Still using bond0 ....

The suffix isn't hard-coded or anything to do with cman really, it's
just a way of distinguishing interfaces.

You need to edit cluster.conf to tell it to use the different name.

If you get despertate then you can always put the IP address in
cluster.conf, but the output from cman_tool nodes doesn't look as nice!

I haven't read that article in detail before but you're right, it makes no mention of changing cluster.conf!

I've fixed that now, thank you.
