.Sh NAME
|
|
.Nm geom_linux_lvm
|
|
.Nd "GEOM based Linux LVM logical volume mapping"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following line in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "options GEOM_LINUX_LVM"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
geom_linux_lvm_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
framework provides support for mapping Linux LVM volumes to GEOM providers.
|
|
.Nm
|
|
currently supports linear stripes with segments on one or more physical disks.
|
|
The parser is able to read LVM2 Text Format metadata, the logical volumes will
|
|
be assembled and made available under
|
|
.Pa /dev/linux_lvm/ .
|
|
The metadata is read-only, logical volumes cannot be allocated or resized.
|
|
.Sh EXAMPLES
|
|
To view which
|
|
.Nm
|
|
devices are available:
|
|
.Bd -literal -offset indent
|
|
# geom linux_lvm list
