Pacemaker determines if a ocf resource is reloadable by reading the resource script's meta_data() output. Take a look at the pacemaker/Dummy script in a text editor. The meta_data() function returns documentation on what the agent is capable of in xml. Pacemaker is looking through the xml output of that meta_data() function for <actions><action name='reload'/></actions> to determine if the resource can reload. Then pacemaker looks through the <parameters/> tags for parameters with unique="0" to determine what parameters are allowed to be reloaded. Hope that helps. -- Vossel > > My questions are: > > 1) Is it possible to somehow debug the decision of the pengine for > the > task?
