FIXMOUNT(8)                 System Manager's Manual                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.
