Re: local node on failover server.

[Jan Klopper <janklopper@xxxxxxxxx>]

I have been going on vacation for a couple of years now (sailing races) 
and it has been a nightmare without anything like a cluster/failover.
That is exactly the reason why i have setup this system.

I fugured we could just do the following:

replace the line that says, ifconfig eth0 add VIP netmask ...
with: noarpctl del VIP RIP.

And the other way around:
replace the line: ifconfig eth0:0 del VIP netmask ...
with noarpctl add VIP RIP

the only point i don't know for sure is:
will the new server begin arping as soon as noarp has been deleted?
the rest of the scripts would remain the same right?
(maybe all but the startup script, but that can be done outside of 
LVS/heartbeat in for example local.start, to add the VIP with noarp like 
any realserver would)
