       fixmount - fix remote mount entries


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


       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.


       -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.


       /etc/mtab           List of current mounts.

       /etc/rmtab          Backup file for remote mount entries on NFS server.

       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

       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.
