Should I Use Lvm When Installing Ubuntu?

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.

Should you use LVM Ubuntu?

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.

Does LVM affect performance?

LVM, like everything else, is a mixed blessing. With respect to performance, LVM will hinder you a little bit because it is another layer of abstraction that has to be worked out before bits hit (or can be read from) the disk. In most situations, this performance hit will be practically unmeasurable.
