Heartbeat starting my resources twice... why?

While working on implementing failover for a JBoss application in heartbeat I had it sometimes fail miserably. After examining the logs files for a while I noticed that it tried to start my service twice.. why?

This was due to multiple errors from my side:

1. I hadn’t implemented the status call for my heartbeat resource script
2. My script didn’t return true when asked to start and it was already started.

According to LSB standard your start / stop scripts should return true even though your service is already started.

Note to self: Learn to read the documentation and not just assume you know how it works (especially not with failover clusters… they are meant to have uptime you know.

Good readings about heartbeat and the resouces scripts.
