Logical Volume Manager

In computer storage, logical volume management or LVM provides a method of allocating space on mass-storage devices that is more flexible than conventional partitioning schemes. In particular, a volume manager can concatenate, stripe together or otherwise combine partitions (or block devices in general) into larger virtual ones that administrators can re-size or move, potentially without interrupting system use.

In OS/2 the Logical Volume Manager (LVM) is the disk management system that replaces the older FDISK-based system in OS/2 Warp Server for e-business, all OS/2 Convenience Package releases, and all versions of eComStation.

The OS/2 LVM has been released under an open source license and ported to Linux; however, the name of the open source version has been changed to "Enterprise Volume Management System" (EVMS).
