LVM is a Logical Volume Manager, a system that introduces a layer of
indirection between your real, hardware, disks and the logical disks
used by the system. Basically it can take multiple disks and join them
into one storage pool, from which you can then create virtual disks.
Another advantage of using LVM is that you can create, remove and
change the disks at runtime easily.

There is a guide for using LVM on an already installed system at
https://help.ubuntu.com/community/SettingUpLVM-WithoutACleanInstall
