>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).</P
|
|
><P
|
|
>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.</P
