Some things to be aware of:

- cluster checks the status of "ftp" and "www" services using the
scripts. If the scripts say the service is running, cluster considers
the service as available. Most service scripts simply look for the
process name or PID to determine if a service is running.

- you have monitor_link turned off on your IP addresses - this means
when you down your eth0 interface, cluster manager isn't going to notice
that those IP addresses aren't working.

With manual fencing, the cluster is going to sit there and wait until
you manually reboot that failed node.
