31.Sh NAME
32.Nm geom_linux_lvm
33.Nd "GEOM based Linux LVM logical volume mapping"
34.Sh SYNOPSIS
35To compile this driver into the kernel,
36place the following line in your
37kernel configuration file:
38.Bd -ragged -offset indent
39.Cd "options GEOM_LINUX_LVM"
40.Ed
41.Pp
42Alternatively, to load the driver as a
43module at boot time, place the following line in
44.Xr loader.conf 5 :
45.Bd -literal -offset indent
46geom_linux_lvm_load="YES"
47.Ed
48.Sh DESCRIPTION
49The
50.Nm
51framework provides support for mapping Linux LVM volumes to GEOM providers.
52.Nm
53currently supports linear stripes with segments on one or more physical disks.
54The parser is able to read LVM2 Text Format metadata, the logical volumes will
55be assembled and made available under
56.Pa /dev/linux_lvm/ .
57The metadata is read-only, logical volumes cannot be allocated or resized.
58.Sh EXAMPLES
