In UnixArena Tutorial series, Here we are going to see about Linux’s Logical volume manager which is default volume manage on all of the Linux flavors which are available now a days in market.In this tutorial, you will learn how to integrate, operate, LVM on Redhat Linux. This training provides instruction on operational management procedures for LVM and you will learn how to install and configure LVM and how to manage disks,volume groups, and volumes by using the command line.The advantage of using LVM is that space can be added to or removed from logical volumes as needed on demand basis.For your kind information , I am not going to explain LVM theory in depth on this tutorial.

Overall LVM configuration Layout:
In this tutorial,we are going to cover the below topics.In the end of these tutorials you will very familiar with Logical volume manager and its operation.Your suggestions are always welcome to improve this tutorial.
