[Linux-cluster] changing configuration

Hey everyone,
	How do I update the IP addresses of existing nodes?
	I have a simple cluster.  I had two nodes on a private network
(10.x.x.x).  I decided to add two more nodes, but they are only on the
public network.  So I wanted to add them as well as change the existing
nodes to use the public network.
	I shut down cman/ccs on all nodes.  I edited cluster.conf.  I
started cman back on one node, and I ensured that cman_tool went to the
new version of the config via "cman_tool version -r N+1".
	The problem is that it still appears to be using the private
network addresses.  I see this in the log and with "cman_tool nodes -a".
	What can I do to fix this, short of hunting down all cman and
openais droppings and removing them?  I want the "right" way :-)
