Our application currently runs on RHEL 6.x using RHCS. With moving to RHEL 7.x looks like we have to use PaceMaker cluster. Without having to re-write the application start and stop script, can the RHCS scripts be directly added to a Pacemaker Resource Group via the command line (of course I have a ip resource added to the group as well).

pcs resource create directory=/home/ --group
pcs resource create apples directory=/home/fruit --group MyResourceGroup

Does the cluster resource manager within pacemaker when it starts/stops the resource group during a failover event or a manual move, call start/stop, so like when I type in "pcs resource move " the pacemaker framework calls the script with the stop option first on node1, then on the new node2, calls the script with the start option, so the output in /var/log/messages would be something like "/home//script stop" where "stop" is furnished by the PaceMaker Framework (or the cluster resource manager within PaceMaker).

although simple, I don't need to be able to control the resources from the GUI (could be done and more polished at a later date).
