[Linux-HA] Almost done with my HA setup, but somethign not working

[Nick Duda]

I rename the restart script for squid. My current setup (based on 
examples on the web) show that if squid fails on the current runing 
server it will try to restart itself. If restart fails it will failover. 
So basically I am trying to make a test case scenario that if the squid 
startup script in /etc/init.d got deleted and squid crashed it should 
failover to the other box.....its not.
