FIXMOUNT(8)                 System Manager's Manual                FIXMOUNT(8)

       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  corre-
              spond  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 notifi-
              cation 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  cau-
              tion,  as  it removes all remote mount entries pertaining to the
              local system, whether or not any filesystems are  still  mounted

       -q     Be  quiet.   Suppresses error messages due to timeouts and "Pro-
              gram 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.

       mountd(8), showmount(8)

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

       Since swap file mounts are not recorded in /etc/mtab, a heuristic  spe-
       cific  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.
