The
geom_linux_lvm framework provides support for mapping
Linux LVM volumes to GEOM providers.
geom_linux_lvm
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.
