![]() To use LVM2 you need 3 things: device-mapper in your kernel, the userspace device-mapper support library (libdevmapper) and the userspace LVM2 tools. Seen below: rootrhel lvcreate -L 500M -n lvlinear LVMvgTEST Logical volume 'lvlinear' created. Here I am going to use a small portion of that volume group to create a linear logical volume titled, very creatively, lvlinear. LVM can be used to create software RAID arrays, to manage multiple disks. That volume group was created by joining two unique 1G physical volumes. It allows users to create logical volumes, which are similar to partitions, but are more flexible and can be easily resized and relocated. It is reasonably backwards-compatible with the original LVM toolset. Linux Logical Volume Manager (LVM) provides a pool of disk space that can be easily allocated and managed for a variety of purposes. 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). LVM2 refers to the userspace toolset that provide logical volume management facilities on linux. How LVM creates layers of abstraction between storage devices and file systems and how to use that to your. ![]() 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. Description Exactly what LVM is and when to use it. 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 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. ![]()
