Oh Come on. It's a storage pool/logical volume with a easy to use GUI &
software raid.

Gee i'll bet veritas, tivoli etc are just amazed at the novelty.


e.g.

http://en.wikipedia.org/wiki/LVM2

"LVM is an implementation of a logical volume manager for the Linux
kernel. It was originally written in 1998 by Heinz Mauelshagen, who based
its design on that of the LVM in HP-UX.

The installers for the Fedora, SuSE and Debian distributions are LVM-aware
and can install a bootable system with a root filesystem on an logical
volume.

The LVM can:

     * Resize volume groups online by absorbing new physical volumes
(PV) or ejecting existing ones.
     * Resize logical volumes online by concatenating extents onto them
or truncating extents from them.
     * Create read-only snapshots of logical volumes (LVM1).
     * Create read-write snapshots of logical volumes (LVM2).
     * Stripe whole or parts of logical volumes across multiple PVs, in
a fashion similar to RAID0.
     * Move online logical volumes between PVs.
     * Split or merge volume groups in situ (as long as no logical
volumes span the split). This can be useful when migrating whole logical
volumes to or from offline storage.

It cannot:

     * Mirror whole or parts of logical volumes, in a fashion similar to
RAID1 or RAID5 mirroring of logical volumes. For this, it is recommended
that one use the Linux software RAID driver to mirror the underlying PVs to
achieve redundancy.
