The GNU/Linux operating system is blessed to have sound partition management tools like GParted which are very easy to use. However, when it comes to the management of 'virtual partitions' known as volumes, things are quite different. There is Linx Volume Management, or LVM for short, however it can only really be used from the command line.
Fedora 14 is the latest update to the Red Hat-sponsored, Linux distribution. It is one of a handful of Linux distributions that use LVM, the Linux Logical Volume Manager, as the default disk partitioning scheme. The installer creates three logical volumes by default, besides the non-LVM /boot partition.
In this test procedure, first we create a new partition (/dev/hda2) using un-partitioned disk space. A new volume group (TestVG) and logical volume (TestLV) are then created using a physical volume created on the partition. An ext3 filesystem is then created on the logical volume, it is checked, and then mounted.
These days most distributions are very easy to use and (for better or worse) abstract away the complex and powerful system underneath. This makes it easier to use but as a result, users often know little about the underlying system. Today we are going to take a look at Logical Volume Management (LVM), which gives users the ability to re-size partitions on the fly.
Fedora 13 is one of the Linux distributions that supports and uses Linux Logical Volume Manager (LVM) as the default disk partitioning scheme. While this is a good thing (it has its benefits), the space allocation to the partitions and logical volumes is not optimal.
LVM (Logical Volume Manager) is a great piece of software which allow you to deal with Logical Volumes. Using LVM along with ext3 filesystem, you are allowed to extend the size of your logical drives which is pretty handy when running out of space.

I recently ordered a brand new PowerEdge T105 server which came with an 80 GB hard disk. I partitioned it with LVM, installed Debian Lenny and moved over the bulk of my things from the old server to the new server. Only one thing remained: my media collection, which is stored on a 500 GB RAID1 array on the old server. That RAID1 array is also partitioned using LVM in a single 500 GB volume group.
