NAME
     gmountver -- control utility for disk mount verification GEOM class

SYNOPSIS
     gmountver create [-v] dev ...
     gmountver destroy [-fv] prov ...
     gmountver list
     gmountver status [-s name]
     gmountver load [-v]
     gmountver unload [-v]

DESCRIPTION
     The gmountver utility is used to control the mount	verification GEOM
     class.  When configured, it passes	all the	I/O requests to	the underlying
     provider.	When the underlying provider disappears	- for example because
     the disk device got disconnected -	it queues all the I/O requests and
     waits for the provider to reappear.  When that happens, it	attaches to it
     and sends the queued requests.

     The first argument	to gmountver indicates an action to be performed:

     create   Cache the	given devices with specified name.  The	kernel module
	      geom_mountver.ko will be loaded if it is not loaded already.

     destroy  Destroy name.

     list     See geom(8).

     status   See geom(8).

     load     See geom(8).

     unload   See geom(8).

     Additional	options:

     -f	     Force the removal of the specified	mountver device.

     -v	     Be	more verbose.

SYSCTL VARIABLES
     The following sysctl(8) variables can be used to control the behavior of
     the MOUNTVER GEOM class.  The default value is shown next to each vari-
     able.

     kern.geom.mountver.debug: 0
	     Debug level of the	MOUNTVER GEOM class.  This can be set to a
	     number between 0 and 3 inclusive.	If set to 0 minimal debug
	     information is printed, and if set	to 3 the maximum amount	of
	     debug information is printed.

     kern.geom.mountver.check.check_ident: 1
	     This can be set to	0 or 1.	 If set	to 0, gmountver	will reattach
	     to	the device even	if the device reports a	different disk ID.

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