Hi Everyone,

I have been trying to setup an NFS v4 File Server but have come across 
an odd issue.  Mounting the /nfs4exports/share appears to be successful 
and the information displayed about partition size and free space seem 
correct but if I try to do anything inside the mounted directory the 
client will just hang.  Does anyone have any idea what I am missing??  I 
have try disabling all firewalls and selinux  but it doesn't seem to 
make any difference

I have taken a look at 
http://www.brennan.id.au/19-Network_File_System.html#nfs 
<http://www.brennan.id.au/19-Network_File_System.html#nfs4>4 
<http://www.brennan.id.au/19-Network_File_System.html#nfs4> and 
http://blog.laimbock.com/2009/05/21/nfsv4-on-centos-53-and-fedora-11/ 
and still can't see what i'm doing wrong

{The Server}

CentOS 5.4  64 Bit

[root at inf1 /]# cat /etc/idmapd.conf
[General]

Verbosity = 9
Pipefs-Directory = /var/lib/nfs/rpc_pipefs
Domain = scms.waikato.ac.nz

[Mapping]

Nobody-User = nfsnobody
Nobody-Group = nfsnobody

[Translation]
Method = nsswitch

[root at inf1 /]# mount -l | grep bind
/export on /nfs4exports/share type none (rw,bind)

And an ls of /nfs4exports/share on NFS Server works

from /etc/fstab
/export  /nfs4exports/share    none    bind    0 0
