Ok, that looks better. Both nodes show up as being memebers
using cman_tool status and cman_tool nodes. Also, seems I
forgot to start rgmanager. Once I started it, the "test" 
service I configured started up. stopping rgmanager, openais, cman
in that order on the second node, caused node1 to fence node2.

clustat still doesn't report correct status for me, but at least
I am getting some status back.

For a start, you can always try cman_tool status / cman_tool nodes, just to
take clustat out of the picture.
