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.

I posted before about HA with 2 squid servers. It's just about done,
but stumbling on something. Everytime i manually cause something to
happen in hopes to see it failover, it doesnt. For example, I get
crm_mon to show everything as I want it, and when I kill squid (and
prevent the xml from restarting it) it just goes into a failed
state...more below. Anyone see anything wrong with my configs?
Server #1
Hostname: ha-1
eth0 - lan (192.168.95.1)
eth1 - xover to eth1 on other server
Server #2
Hostname: ha-2
eth0 - lan (192.168.95.2)
eth1 - xover to eth1 on other server
ha.cf on each server:
bcast eth1
mcast eth0 239.0.0.2 694 1 0
node ha-1 ha-2
crm on
Not using haresources because of crm
Here is the output from crm_mon:

If squid stops on the current heartbeat serer, ha-1, it will restart
within 60sec...so the scripting is working. If i stop the squid
process and rename it in /etc/init.d/squid to something else, the
script wont be able to execute the squid start and should failover to
ha-2, but it doesnt, instead this appears (on both ha-1 and ha-2):
What exactly do you "rename" and how? It's likely the cluster is
behaving sane and you're just creating a testcase you don't understand.
