<p class="Pp">The <code class="Nm">geom_linux_lvm</code> framework provides
    support for mapping Linux LVM volumes to GEOM providers.
    <code class="Nm">geom_linux_lvm</code> 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 <span class="Pa">/dev/linux_lvm/</span>. The metadata is
    read-only, logical volumes cannot be allocated or resized.</p>
