.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is proposed in the
|
|
.Tn NFS
|
|
RPC specification; see
|
|
.Rs
|
|
.%T "NFS Version 3 Protocol Specification"
|
|
.%O "RFC 1813, Appendix I"
|
|
.Re
|
|
It uses remote procedure calls to remove mount entries from
|
|
.Pa /var/db/mountdtab
|
|
on the remote NFS server.
|
|
It is called automatically
|
|
without any parameters during startup and shutdown of
|
|
the system.
|
|
This ensures that
|
|
.Xr showmount 8
|
|
does not display old and expired entries.
|
|
The
|
|
.Nm
|
|
utility
|
|
is only needed on client side, where
|
|
.Xr mount_nfs 8
|
|
adds a mount entry with the current date to
|
|
.Pa /var/db/mounttab ,
|
|
and
|
|
.Xr umount 8
|
|
removes the entry again.
|
|
The
|
|
.Nm
|
|
utility
|
|
cares about all remaining entries in this table which result from crashes
|
|
or unproper shutdowns.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width indentxxx
|
|
.It Fl e Ar expire
|
|
All entries which are not actually mounted or older than
|
|
.Ar expire
|
|
(seconds) are removed from
|
|
.Pa /var/db/mounttab .
|
|
This may be the case
|
|
for DNS changes or long out of service periods.
|
|
Default expire time
|
|
is 86400 seconds (one day).
|
|
.It Fl h Ar host
|
|
Only remove the specific hostname.
|
|
Send a UMNTALL RPC to the NFS server.
|
|
.It Fl k
|
|
Keep entries for existing NFS file systems.
|
|
Compare the NFS file systems from
|
|
the mounttab against the kernel mountlist and do not send the RPC to
|
|
existing mount entries.
|
|
Useful during startup of the system.
|
|
It may be
|
|
possible that there are already mounted NFS file systems, so calling
|
|
RPC UMOUNT is not a good idea.
|
|
This is the case if the user has rebooted
|
|
to 'single user mode' and starts up the system again.
|
|
.It Fl p Ar path
|
|
Only remove the specific mount-path.
|
|
Send a UMOUNT RPC to the NFS server.
|
|
This option implies the
|
|
.Fl host
|
|
option.
|
|
.It Fl v
|
|
Verbose, additional information is printed for each processed mounttab
|
|
entry.
