GMOUNTVER(8) System Manager's Manual GMOUNTVER(8) NAME gmountver -- control utility for disk mount verification GEOM class SYNOPSIS gmountver create [-v] prov ... gmountver destroy [-fv] name 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 de- vice 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 opera- tion 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. 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 variable. kern.geom.mountver.debug: 0 Debug level of the MOUNTVER GEOM class. This can be set to a num- ber between 0 and 3 inclusive. If set to 0 minimal debug informa- tion is printed, and if set to 3 the maximum amount of debug infor- mation is printed. kern.geom.mountver.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. SEE ALSO geom(4), geom(8) HISTORY The gmountver utility appeared in FreeBSD 9.0. AUTHORS Edward Tomasz Napierala <trasz@FreeBSD.org> FreeBSD ports 15.1 May 18, 2015 GMOUNTVER(8)
