LVM can be extremely helpful in dynamic environments, when disks and partitions are often moved or resized. While normal partitions can also be resized, LVM is a lot more flexible and provides extended functionality. As a mature system, LVM is also very stable and every Linux distribution supports it by default.
What is the advantage of using LVM in Linux?
The main advantages of LVM are increased abstraction, flexibility, and control. Logical volumes can have meaningful names like “databases” or “root-backup”. Volumes can be resized dynamically as space requirements change and migrated between physical devices within the pool on a running system or exported easily.

Should I use LVM with Linux Mint?
LVM is a fine idea for multiple small drives or larger servers but with the lower cost of multi-terabyte drives it’s not a lot of use for home users. There is, however, one thing that I found it good for. LVM works great for striping multiple drives together for raid 0 type configurations.
What is difference between LVM and standard partition?
standard partition – A standard partition can contain a file system or swap space, or it can provide a container for software RAID or an LVM physical volume. logical volume (LVM) – Creating an LVM partition automatically generates an LVM logical volume. LVM can improve performance when using physical disks.
How does LVM work in Linux?
In Linux, Logical Volume Manager (LVM) is a device mapper framework that provides logical volume management for the Linux kernel. Most modern Linux distributions are LVM-aware to the point of being able to have their root file systems on a logical volume.
