The LVM2 plug-in provides compatibility with the new volume format introduced by the LVM2 tools from Red Hat (previously Sistina). This plug-in is very similar in functionality to the LVM plug-in. The primary difference is the new, improved metadata format. LVM2 is still based on the concept of volume groups (VGs), which are constructed from physical volumes (PVs) and produce logical volumes (LVs).
Just like the LVM plug-in, the LVM2 plug-in represents volume groups as EVMS containers and represents logical volumes as EVMS regions. LVM2 containers combine storage objects (disks, segments, or other regions) to create a pool of freespace. Regions are then created from this freespace, with a variety of mappings to the consumed objects.
