It seams that return code of 5 from a LSB script confuses the cluster.
I have made my init script to be LSB compliant, it passes the tests
here[1], but I have also implemented what it is mentioned here [2]
regarding the exit codes.
I have implemented the exit code 5 which causes troubles because when
the cluster run the monitor on the slave node, where no resources are
active, gets rc=5.
If I remove the exit 5 everything is fine. Is this a expected behavior?
