NFS : add official support for UNC paths from Windows clients

we are using NFS on z/OS2.4. We finished a migration project from DFS to NFS because DFS is no longer supported in z/OS.2.4. Our clients are NFS version3 clients on Windows servers and workstations accessing z/OS NFS by using kerberos.

Our Windows applications do not use NFS mount commands with a drive letter as recommended in NFS but UNC paths :

The main reasons we decided to continue with UNC paths are :

  • our previous DFS applications also only used UNC paths which made the conversion to NFS much easier (we just had to change the path names and not the code)

  • most of our applications run on Windows servers as a Windows service and not as an application started by a user that is logged on. We never succeeded to do a mount command with a drive letter from an application running as a Windows service. It seems not to be supported by Windows.

Although our NFS applications are running ok we have some operational issues because of the use of UNC paths :

  • lot's of INACTIVE mount points

  • Continious growth of the virtual storage used by the NFS server on z/OS

As a bypass we stop/start the NFS server once a day
