lvm

LVM, which stands for Logical Volume Manager, is a command line tool used in Linux systems to manage disk partitions. It offers advanced features such as creating, resizing, and deleting logical volumes that can span across multiple physical disks. LVM provides flexibility by allowing you to dynamically allocate and reallocate disk space as needed, without destroying or recreating partitions. With LVM, you can combine multiple physical disks into a single volume group, which can then be divided into smaller logical volumes. These logical volumes can be resized on the fly, even while the system is running, providing efficient disk management and storage utilization. LVM also supports features like snapshots, which allow you to create a read-only copy of a logical volume, preserving the state of the data at a specific point in time. Additionally, LVM provides tools and utilities to monitor and troubleshoot logical volumes, ensuring the integrity and availability of data stored on them.
