Some nitpicking first :-)
There is no such thing as a "GFS server" or "GFS client". The nodes that
are mounting a GFS filesystem are usually called "GFS nodes"
However, there are indeed "GNBD servers" and "GNBD clients that exports
and imports blockdevices.
So I understand your setup to be one node (the Ubuntu node) is acting as
a GNBD server and exports two disk drives.
Correct.
And then there are two nodes (the RHEL4 nodes) that acts as GNBD clients
and imports the two disk drives.
Correct.
On these disk drives is the GFS filesystem.
No, these are raw partiitons as describres in sources.redhat.com
(min-gfs.txt).
I have not used CLVM with GFS yet, but with the old pool-driver (the
volume manager that was shipped with GFS previously) this setup could be
done in 2 different ways:
1. Combine the two disk drives on the GNBD server and export _one_ volume
In this case I need to run clvm on ubuntu server, right??
2. Export _two_ volumes from the GNBD server and combine the volumes on
the GNBD client / GFS nodes.
I would assume both ways would work with CLVM.

Hi all,
I am testing Cluster/GFS suite under my vmware lab. I have installed
two RHEL 4 with CS and GFS support. Another machine acts as a GFS
server (Ubuntu breezy server that has rhcs/gfs included).
Ubuntu server has two phisycal disks exported by gnbd daemon and
RHEL import these disks as a GFS clients. But I would like to export
these disks as a unique disk using LVM. Then, I need to start clvm
process under Ubuntu server or on RHEL clients??? Is it possible to
accomplish this?.
Thanks.
