GEOM(8)			FreeBSD	System Manager's Manual		       GEOM(8)

NAME
     geom -- universal control utility for GEOM	classes

SYNOPSIS
     geom class	command	[options]

DESCRIPTION
     The geom utility is used to control various GEOM classes.	A class	has to
     be	aware of geom(8) comunication methods, but there are also some stan-
     dard commands which can be	used for existing, not geom(8) aware classes.
     Here is the list of standard commands:

     help    List all available	commands for the given class.

     list    Print detailed information	(within	the given class) about all
	     geoms (if no additional arguments were specified) or the given
	     geoms.  This command is only available if the given class exists
	     in	the kernel.

     load    Load the kernel module that implements the	given class.  This
	     command is	only available if the class does not yet exist in the
	     kernel and	the file geom_<class>.ko can be	found in one of	the
	     directories specifed in kern.module_path sysctl.

     unload  Unload the	kernel module which implements the given class.	 This
	     command is	only available if the given class is loaded as a ker-
	     nel module.

     Class-specific commands are implemented as	shared libraries which are
     stored in /lib/geom/ directory and	are loaded via dlopen(3) function when
     the class name is known.  When a class-specific shared library exists, a
     direct utility should also	be available under the name of gclass.

     Currently available classes which are aware of geom(8):

	   +o   CONCAT
	   +o   LABEL
	   +o   MIRROR
	   +o   NOP
	   +o   RAID3
	   +o   STRIPE

EXAMPLES
     The following example shows how to	set up a stripe	on three disks for
     automatic configuration:

	   geom	stripe label -v	-s 65536 data /dev/da0 /dev/da1	/dev/da2
	   or:
	   gstripe label -v -s 65536 data /dev/da0 /dev/da1 /dev/da2

     Print the list of all providers from the DISK class:

	   geom	disk list

     Unload a kernel module which implements the MD class:

	   geom	md unload

DIAGNOSTICS
     Exit status is 0 on success, and 1	if the command fails.
