Gluster users - Dec 2010 - howto disable gluster nfs on one computer

Many of the computers in our cluster are diskless and those computers need to
have disk space exported to them.  The space for diskless booting is supplied
by a server within the cluster that does have disks and that also supplies a
couple of bricks to a glusterfs file system.  The space for diskless booting
is *not* within a glusterfs file system.  The servers for other bricks in
the cluster have no special nfs needs.  I need to be able to disable glusterfs
nfs on the server for diskless booting and no other server so I can have use
of the regular nfs server on that server.  How would I do that?  Is it even
possible?

Another solution, like moving the glusterfs nfs service to another port would
also be acceptable.  However I would likely still need have to have the
regular nfs service the one that portmap returns for that one server.

    As a temporary solution you can kill the process that is exporting 
the volume via NFS. The Gluster NFS process can be identified by 'ps -ef 
| grep nfs-server.vol'.
The process will restart when glusterd does, or when any changes to the 
volume are made.

Thanks,

Craig
