Should I use LVM when installing Linux?

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.

Should I use LVM with the new Ubuntu installation?

If you are using Ubuntu on a laptop with only one internal hard drive and you don’t need extended features like live snapshots, then you may not need LVM. If you need easy expansion or want to combine multiple hard drives into a single pool of storage then LVM may be what you have been looking for.

What is the need of LVM in Linux?

Uses. LVM is used for the following purposes: Creating single logical volumes of multiple physical volumes or entire hard disks (somewhat similar to RAID 0, but more similar to JBOD), allowing for dynamic volume resizing. Performing consistent backups by taking snapshots of the logical volumes.

What is the difference between LVM and VxVM?

An LVM volume is composed of fixed length extents. LVM volumes can be mirrored or striped, but mirrored-stripe and striped-mirror layouts are not supported. VxVM volumes consist of one or more plexes/mirrors holding a copy of the data in the volume which in turn are made up of subdisks with arbitrary length.

What is the advantage of 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.

What is difference between fdisk and LVM?

As far as I know, there is no bootloader yet that could boot from a LVM-only disk. LVM allows a Logical Volume to span multiple physical disks/RAID sets. With FDISK, you can extend an existing partition only if there is free space on the disk immediately after the partition.
