[rhn-users] RH cluster manager - floating IP adress

[Espen Ekeroth]

Update: The problem is not related to the ip adress but the running of the 
user script. If the IP adress is set, and the user application script is 
started from command line everything works. If the user script is started 
from the cluster manager it does not work. The user script looks like 
this:

#!/bin/sh

case "$1" in
start)
        su - condico -c start.sh
        ;;
stop)
        su - condico -c clean.sh
        ;;

status)
        /home/condico/status
        exit $?
        ;;

*)
        echo "usage: $0 {start|stop}"
        exit 1
        ;;
esac

exit 0


It seems like the environment some way gets different when the script is 
run from the cluster deamon compared to when run from command line. The 
script "start.sh" is a shell script that start our application. We are 
running the application with HA-Linux with no problem like this.

Update: if I add the IP address my selv: 

ifconfig eth0:1 10.175.158.14 

it does not affect my application. So what is RH Cluster Manager doing?

Can anyone tell me what cluster manager do when it assign an IP adress to 
a service? 

I have problem running my application on the physical node when the 
service with the floating ip is running on the node. It seems like the 
cluster manager is doing something to the routing table or similar (but it 
is not displayed when checking with netstat -rn)
