NAME

geom_linux_lvm - GEOM based Linux LVM logical volume mapping

SYNOPSIS

To compile this driver into the kernel, place the following line in your kernel configuration file:

options GEOM_LINUX_LVM

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:

geom_linux_lvm_load="YES"

DESCRIPTION

The ifconfig framework provides support for mapping Linux LVM volumes to GEOM providers. ifconfig 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 /dev/linux_lvm/ The metadata is read-only, logical volumes cannot be allocated or resized.
