NFS Root problem

[sunnox]

Hi,

I have a diskless workstation that is mounting is root partition from an NFS3 
server.
But each time the diskless workstation is mounting the root partion with 
NFSv2 and not 3
And mount /home partition in NFSv3
See:
http1:~# mount 
/dev/root on / type nfs 
(rw,v2,rsize=4096,wsize=4096,hard,udp,nolock,addr=10.0.7.1) none on /proc 
type proc (rw) devpts on /dev/pts type devpts (rw) 10.0.7.1:/home on /home 
type nfs (rw,v3,rsize=8192,wsize=8192,hard,udp,nolock,addr=10.0.7.1)

My configuration:

NFS server

linux 2.4.7+GFS patch
nfs-utils-0.3.1
util-linux-2.11h.tar.gz

NFS client

linux 2.4.7+ NFS client patch (all)

The root partition mounted from the diskless client is a GFS partition 
The /home partion mounted from the diskless client is a reiserfs partition

Thanks for any help
