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