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#nfs44 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@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@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
