FIXMOUNT(8L)					     FIXMOUNT(8L)

NAME
       fixmount - fix remote mount entries

SYNOPSIS
       fixmount [ -adervq ] [ -h name ] host ...

DESCRIPTION
       fixmount	 is  a	variant	 of  showmount(8) that can delete
       bogus mount entries in  remote  mountd(8C)  daemons.   The
       actions	specified  by  the options are performed for each
       host in turn.

OPTIONS
       -a -d -e
	      These options work as in showmount(8)  except  that
	      only  entries  pertaining	 to  the  local	 host are
	      printed.

       -r     Removes those remote mount entries on host that  do
	      not  correspond  to current mounts, i.e., which are
	      left-over	 from  a  crash	 or  are  the  result  of
	      improper	mount  protocol.  The actuality of mounts
	      is verified using the entries in /etc/mtab.

       -v     Verify remote mounts.  Similar to	 -r  except  that
	      only  a  notification  message  is printed for each
	      bogus entry found.  The remote mount table  is  not
	      changed.

       -A     Issues  a	 command  to  the remote mountd declaring
	      that ALL of its filesystems  have	 been  unmounted.
	      This should be used with caution, as it removes all
	      remote mount entries pertaining to the  local  sys-
	      tem,  whether  or	 not  any  filesystems	are still
	      mounted locally.

       -q     Be quiet.	 Suppresses error messages due	to  time-
	      outs  and	 "Program  not	registered", i.e., due to
	      remote hosts not	supporting  RPC	 or  not  running
	      mountd.

       -h name
	      Pretend the local hostname is name.  This is useful
	      after the local hostname has been changed and rmtab
	      entries  using  the  old	name  remain  on a remote
	      machine.	Unfortunately,	most  mountd's	won't  be
	      able   to	  successfully	handle	removal	 of  such
	      entries, so this option is  useful  in  combination
	      with -v only.
	      This  option  also  saves	 time  as  comparisons of
	      remotely recorded and local  hostnames  by  address
	      are avoided.

FILES
       /etc/mtab	   List of current mounts.
       /etc/rmtab	   Backup  file	 for remote mount entries
			   on NFS server.

SEE ALSO
       showmount(8), mtab(5), rmtab(5), mountd(8C).

BUGS
       No attempt is made to verify the information in	/etc/mtab
       itself.

       Since  swap  file  mounts are not recorded in /etc/mtab, a
       heuristic specific to SunOS is used to  determine  whether
       such  a	mount is actual (replacing the string "swap" with
       "root" and verifying the resulting path).

       Symbolic links on the server will cause the  path  in  the
       remote  entry  to  differ  from	the one in /etc/mtab.  To
       catch those cases, a filesystem is also deemed mounted  if
       its  local  mount  point is identical to the remote entry.
       I.e.,	  on	  a	 SunOS	    diskless	  client,
       server:/export/share/sunos.4.1.1	 is  actually /usr/share.
       Since the local mount point is  /usr/share  as  well  this
       will be handled correctly.

       There  is no way to clear a stale entry in a remote mountd
       after the local hostname (or whatever reverse name resolu-
       tion  returns  for  it) has been changed.  To take care of
       these cases, the remote /etc/rmtab file has to  be  edited
       and mountd restarted.

       The  RPC	 timeouts for mountd calls can only be changed by
       recompiling.  The defaults are 2 seconds for client handle
       creation and 5 seconds for RPC calls.
