I just very recently upgraded my NW 6.0 server to NW 6.5 and found a couple of issues with my NFS mounts.

RESOLVED ISSUE:
First, the exports listed in EXPORTS are now case sensitive. Furthermore, the NFS namespace does not necessarily match the long name space shown in Windows. For example, servername\data:FOLDER on windows may appear as servername\data:folder in NFS. To verify, check the properties of the folder in NWADMIN. Until I corrected the character case, my exports were not showing up on my Linux hosts.

UNRESOLVED ISSUE:
Once I mount a NFS directory on my Netware 6.5 server, I cannot use a exportfs -u command to remove the mount on Linux. For example, I exectute the following to create a mount:
mount 172.16.0.120:/DATA/CO /mnt/co

The mount shows up as the following after typing "mount" from the CLI:
172.16.0.120:/DATA/CO on /mnt/co type nfs (rw,addr=172.16.0.120)

When I try to remove the mount using the command below, the mount 0still shows up as shown in the last mount command:
exportfs -u 172.16.0.120:/DATA/CO

If I do a "umount -a", the mount will successfully diconnect.

My knowledge of Linux is very limited, but this process worked fine on my NW 6.0 server.
