Logical Volume Management (LVM)
SearchDataCenter, Thursday, December 14,2023
Logical volume management (LVM) is a form of storage virtualization that offers system administrators a more flexible approach to managing disk storage space than traditional partitioning. This type of virtualization tool is located within the device-driver stack on the operating system.
Logical volume management in Linux with an example
LVM is a method of disk space management in the Linux operating system (OS). By creating a layer of abstraction over physical storage, LVM also allows system administrators (sys admins) to manage storage volumes across multiple physical hard disks.
With LVM, sys admins can increase disk input/output (I/O) by adding disk space to what is known as a "logical storage volume" (or simply "logical volume"). These logical volumes provide more flexibility for disk space creation, administration and management compared to traditional storage management methods that directly use physical storage and increase the maximum capacity of individual hard disk drives.
