FIXMOUNT(8)               BSD 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 notifica-
             tion 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
             file systems 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 file systems are still mounted
             locally.

     -v      Be quiet.  Suppresses error messages due to timeouts and
             ``Program not Registered'', i.e., due to remote hosts not sup-
             porting 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.

SEE ALSO
     mtab(5), rmtab(5), mountd(8), showmount(8)

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 spe-
     cific 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 file system 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.
