some correction to spec file (definition of 'ns' volume was missing in
earlier mail).
NOTE : In this case, unify can be used on the client side too, (using 3
protocol/client with "option remote-subvolume usb1", "option
remote-subvolume usb2", and "option sub-volume nfs") but server side
unification will work out better as it will be quite faster as unify has
posix directly under it.

Hi Richard,
Yes, you can't directly use the 1FreeBSD server as glusterfsd server yet.
But your idea is perfect, you can export the FreeBSD server's disk using
NFS. and in the server where you have Linux, use it as a posix translator.
Assume you have
/mnt/usb1 <- first USB disk
/mnt/usb2 <- second USB disk
/mnt/freebsd <- NFS exported freebsd partition.
now your server config will look like
----
volume usb1
type storage/posix
directory /mnt/usb1
end-volume
volume usb2
type storage/posix
directory /mnt/usb2
end-volume
volume nfs
type storage/posix
directory /mnt/freebsd
end-volume
volume ns
type storage/posix
directory /tmp/namespace # you can change it according to your needs
end-volume
volume unify
type cluster/unify
subvolumes nfs usb1 usb2
option namespace ns
option scheduler rr
end-volume
volume server
...
option auth.ip.unify.allow *
end-volume
------
Now you can have a client spec with just a client protocol, which connects
to unify ("option remote-subvolume unify")
