FIXMOUNT(8L)FIXMOUNT(8L)NAMEfixmount - fix remote mount entries
SYNOPSISfixmount [ -adervq ] [ -h name ] host ...
DESCRIPTIONfixmount is a variant of showmount(8) that can delete
bogus mount entries in remote mountd(8C) 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 sys-
tem, whether or not any filesystems are still
mounted locally.
-q Be quiet. Suppresses error messages due to time-
outs 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.
SEE ALSOshowmount(8), mtab(5), rmtab(5), mountd(8C).
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 resolu-
tion 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.
