NAME
       unshare_nfs  -  make local NFS file systems unavailable for mounting by
       remote systems

SYNOPSIS
       unshare [-F nfs] pathname


DESCRIPTION
       The unshare command makes local file systems unavailable  for  mounting
       by  remote  systems.  The  shared file system must correspond to a line
       with NFS as the FSType in the file /etc/dfs/sharetab.

OPTIONS
       The following options are supported:

       -F    This option may be omitted if NFS is the first file  system  type
             listed in the file /etc/dfs/fstypes.


FILES
       /etc/dfs/fstypes


       /etc/dfs/sharetab

NOTES
       If  the  file system being unshared is a symbolic link to a valid path-
       name, the canonical path (the path which  the  symbolic  link  follows)
       will be unshared.


       For   example,  if  /export/foo  is  a  symbolic  link  to  /export/bar
       (/export/foo -> /export/bar), the following unshare command will result
       in /export/bar as the unshared pathname (and not /export/foo):

         example#  unshare -F nfs /export/foo




       For  file  systems that are accessed by NFS Version 4 clients, once the
       unshare is complete, all NFS Version  4  state  (open  files  and  file
       locks)  are released and unrecoverable by the clients. If the intent is
       to share the file system after some administrative action, the NFS dae-
       mon  (nfsd)  should first be stopped and then the file system unshared.
       After the administrative action is complete, the file system would then
       be shared and the NFS daemon restarted. See nfsd(1M)
