[Linux-cluster] use of netgroup as NFS client resource target?

[bergman at merctech.com]

Is it possible to use netgroups to define NFS shares, rather than per-client?

Specifically, when creating an resource of type "NFS Client", can the "target" 
be a netgroup instead of the name of a single client?

On a conventional NFS server, /etc/exports might look something like:

	/homedirs		@servers(rw)
	/homedirs		@desktops(rw)
	/bindir		@servers(ro)
	/logdir		@servers(rw)

Under RHCS, it seems as if each member of the netgroups (@servers, @desktops)
must be defined as a separate NFS client and set up as a separate resource.

This doesn't scale well in environments with significant numbers of NFS 
clients, particularly if they share subnets with machines that should not have 
NFS access to the shares.



Environment:
	CentOS 5.4 (2.6.18-164.15.1.el5)
	RHCS (cman) 2.0.115-1.el5_4.9

Thanks,

Mark
