The Logical Volume Manager for Linux (common files) LVM includes all of the support for handling read/write operations on physical volumes (hard disks, RAID-Systems, magneto optical, etc., multiple devices (MD), see mdadd(8) or even loop devices, see losetup(8)), creating volume groups from one or more physical volumes and creating one or more logical volumes in volume groups.
