**********************************************************

LVM is the established standard for on-line disk storage management
under Linux.

The aims of this talk are:

  To introduce existing LVM concepts and tools under Linux;

  To discuss the architecture used for the new LVM2/device mapper
  in the 2.6 kernel and the extra features and performance
  improvements it provides.

LVM2 is a new backwards-compatible implementation of LVM using a
lightweight kernel driver known as the "device mapper".

The new framework supports:
  Writeable high-performance snapshots;
  Sophisticated remapping tools;
  Greatly enhanced configurability;
  Human-readable (and editable) configuration backups;
  Atomic metadata updates;
  Improved data recovery in the event of disk failure;
  Cluster-awareness.
