+.Sh DESCRIPTION
+The
+.Nm
+utility is used for setting up transparent providers on existing ones.
+Its main purpose is testing other GEOM classes, as it allows force providers
+removal and I/O errors symulation with a given probability.
+It is also a good starting point for implementing new GEOM classes.
+.Pp
+The first argument to
+.Nm
+indicates an action to be performed:
+.Bl -tag -width ".Cm configure"
+.It Cm create
+Setup a transparent provider on the given devices.
+If operation succeded, new provider should appear with name
+.Pa /dev/<dev>.nop .
+The kernel module
+.Pa geom_nop.ko
+will be loaded if it is not loaded already.
+.It Cm configure
+Configure existing transparent provider. At the moment it is only used
+for changing failure probability.
+The kernel module
+.Pa geom_nop.ko
+will be loaded if it is not loaded already.
+.It Cm destroy
+Turn off transparent providers for the given devices.
+.It Cm list
+List currently configured providers.
+.It Cm load
+Load
+.Pa geom_nop.ko
+kernel module.
+.It Cm unload
+Unload
+.Pa geom_nop.ko
+kernel module.
+.El
+.Pp
+Additional options:
+.Bl -tag -width ".Fl f Ar failprob"
+.It Fl f
+Force the removal of the specified striped device.
+.It Fl f Ar failprob
+Specifies failure probability in percentage.
+.It Fl v
+Be more verbose.
+.El
+.Sh EXAMPLES
+The following example shows how to create transparent provider for disk
+.Pa /dev/da0
+with 50% failure probability.
+.Bd -literal -offset indent
+gnop create -v -f 50 /dev/da0
+.Ed
+.Sh DIAGNOSTICS
+Exit status is 0 on success, and 1 if the command fails.
