[Linux-HA] Newbie - Nodes on different subnet

[Todd Lyons]

Lars Marowsky-Bree wanted us to know:

That little tidbit of information would be fantastic in the LVS Howto
Horms, in the section on LVS and heartbeat failover.  I remember seeing
in a few different places that "the config files should be identical".
In the case of haresources, this is obvious and easy to do.  But then
you come to the ha.cf and see a ucast setting that requires the address
of the node you want to ping.  It's not readily obvious that you do
indeed make them identical and that the local process is smart enough to
ignore the one for itself.
