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.
