My suggestion here is theoretical and not tested.... I think you want to have a single "resource" with different service names.  For example,

<rm>
  <resources>
       <fs name="OptAppFS" device=/dev/mapper/VolGroup00-optvol .....>
  </resources>  
       <service name="Central_FS" .....>
             <fs ref="OptAppFS"  ....>
       </service>
       <service name="Collector_FS" .....>
             <fs ref="OptAppFS"  ....>
       </service>
</rm>
