[Linux-cluster] updating running cluster.conf

[chekov at ucla.edu]

I've been running a two-node cluster for a month or so and finally got 
myself a couple of APC master switches to perform automatic fencing.
I want to update my cluster.conf file to reflect the new fencing method but 
I'd like to do it without an interruption in service.
When I join a node the cluster simply copies over the old cluster.conf file 
to the new nodes /etc/cluster directory.  So simply joining a new node with 
a new config file doesn't do it.
I tried using "cman_tool version -r" in an attempt to update the conf 
version.  However now it just rejects node addition in general (and does 
not update the running cluster.conf file)...

in short, I don't know how to introduce the new changes without taking down 
all nodes.  any ideas?
