gmountver – control utility for disk mount verification GEOM class

SYNOPSIS DESCRIPTION SYSCTL VARIABLES EXIT STATUS SEE ALSO HISTORY AUTHORS

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

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	Enable mount verification for the given provider. If the operation succeeds, a new GEOM provider will be created using the given provider's name with a ‘.mountver’ suffix. 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.

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

The gmountver utility appeared in FreeBSD 9.0 .
