A new parameter (-w) has been added to the fence_tool utility in RHEL5.3. In 
the latest open-sharedroot preview packages the -w option is used. If your 
fence_tool version does not support -w, the join command will fail. 
The rpm changelog shows the following:
# rpm -q --changelog cman
* Wed Dec 03 2008 Chris Feist <cfeist at redhat.com> - 2.0.84-2_el5_2.3
- Added missing patch to allow delaying fence_tool joins.
- Resolves rhbz#474467
