   When you boot from the install CD you are not in a cluster, so the
   quorum rules which apply when you boot from the system disk do
   not apply when you boot from the CD.

   You will want to review your votes, quorum, and cluster common file
   locations to make sure the rest of the nodes can remain in normal
   operation. Mkae sure to use the "remove_node" option when you
   shut down so that quorum will be adjusted.
