attempting to shut down openais on the node running the resources after

resources continue to run on the that node even after openais is stopped.<o:p></o:p></span></span></p>

what happens when I force standby, and I notice that using the first syntax
causes te_rsc_command to be executed to send a shut down message to the node where
the resources are running (which seems to work), while using the second syntax
causes te_pseudo_action to be called in approximately the same place in the log,
but no shutdown of resources happens (I can’t really tell what this is
supposed to be doing).<o:p></o:p></span></span></p>
