NAME
     unsharenfs - 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


ATRIBUTES
     See attributes(5) for descriptions of the  following  attri-
     butes:

NOTES
     If the file system being unshared is a symbolic  link  to  a
     valid  pathname, the canonical path (the path which the sym-
     bolic 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  daemon  (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)
