I am no expert in clustering, or hot stand by machines - so in the
config you have in mind - is the floating IP not associated with a fixed
name so the consumers dont know that the machine is being switched over?
If so both active and passive could have as their /etc/hosts files:
127.0.0.1 localhost.localdomain localhost
1.2.3.1 m1.my.dom m1
1.2.3.2 m2.my.dom m2
1.2.3.4 float.my.dom float
Then I assume you need to weewee on arp a little and do something like
ip address add xxx ..
and delete it off the failing one etc etc ... ?
On the other hand - you probably dont need any of this as DNS is
probably doing it all no ?
I'll leave this to the failover, clusterer experts ..
