.TH nfssetlock 8nfs
.SH Name
nfssetlock \- turn on or off the NFS locking service
.SH Syntax
\fB/etc/nfssetlock\fR \fIoption\fR
.SH Description
.NXR "nfssetlock command"
.NXR "NFS locking service" "turning on the"
.NXR "NFS locking service" "turning off the"
The
.PN nfssetlock
command turns the NFS locking service on or off at the kernel level.
By default,
the NFS locking service is turned off.
.PP
If the NFS locking service is turned off,
local locking is active.
Local locking only coordinates the dispersal of advisory locks to
local files and file regions.
The NFS locking service coordinates the dispersal of
advisory locks to both local
and remote files and file regions through the
.PN fcntl
and
.PN lockf
primitives.
.PP
Only the superuser or root can run
.PN nfssetlock .
The best way to run
.PN nfssetlock
is through the
.PN nfssetup
command,
which provides an interactive means for enabling and disabling
the NFS locking service.
.SH Restrictions
If you run
.PN nfssetlock
manually,
you must issue it while the system is in single-user mode.
Otherwise,
the locking information could become lost during the transition
between local and NFS locking.
.SH Options
.IP \fBon\fR 7
Turn on the NFS locking service.
.IP \fBoff\fR
Turn off the NFS locking service.
.SH Files
.PN /etc/rc.local
