What is LVM why we use LVM

Question

Accepted Answer

LVM (Logical Volume Manager) is a disk management tool used in Linux systems to manage storage devices and create logical volumes.

LVM allows for easy management of storage by abstracting physical storage devices into logical volumes.
It provides features like volume resizing, snapshots, and striping for improved performance and flexibility.
LVM enables dynamic allocation of storage space, making it easier to add or remove storage devices without disrupting the system.
It allows for the creation of logical volumes that span multiple physical disks, providing redundancy and improved performance.
Example: Creating a logical volume called 'data' that spans two physical disks (/dev/sdb and /dev/sdc) using LVM commands.
