Novell NetWare 6.5 Support Pack 7
An administrator logs in to iManager 2.7 and selects File Protocols, NFS (NetWare). After selecting a server to manager, the right side of the screen just goes blank. Or, if this already happened previously, the NFS Admin screen may be blank even before a server is selected.
This issue is caused by the presence of invalid export lines in the SYS:\ETC\EXPORTS file. It is solved in the NFS Admin plugin updates in NetWare 6.5 SP8.
It can also be corrected manually (without plugin update), by removing or correcting invalid entries:
Edit the SYS:\ETC\EXPORTS file of the server being managed. Check for invalid lines. These could come around for a variety of reasons. An example: A volume was previously exported; then that volume was deleted, but the entry is still there. That entry is now invalid.
The entry may even already be tagged by iManager as invalid, with a leading "!" (exclamation point). Either way, remove any invalid lines (other than simple comments that begin with #).
If a completely new / clean exports file is desired (but with original comments intact) one can be copied from SYS:ETC\NFS\ExportsTemplate.txt
