FIXMOUNT(8)									      FIXMOUNT(8)

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(8) 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 system, whether or not any filesystems are still
	      mounted locally.

       -q     Be quiet.  Suppresses error messages due to timeouts 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.

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 resolution 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.
