One more question: heartbeat & haproxy

[Fred Leeflang]

Hi,

A last question for now; The haproxy loadbalancers listen to dual IP 
addresses, ideally one of these IP addresses is active on a host, this 
is done through heartbeat. When one virtual IP address disappears, 
heartbeat will make the IP address active on the second host and haproxy 
will there listen to both. This approach I've tested and it works.

However, when haproxy stops for some reason on either node heartbeat 
should detect this and shut down. This is more of a heartbeat question 
than a haproxy question I guess but I'm hoping you folks on here know 
how to do this as well. The simplest way would be to simply to have a 
shell script check if haproxy is running, if not shutdown heartbeat on 
the node; Just don't know if this is the most elegant way.

Thanks,
Fred Leeflang
