In this series of video tutorials, you will learn what LVM is and when you should use it. You’ll discover how LVM creates and uses layers of abstraction between storage devices and file systems including Physical Volumes, Volume Groups, and Logical Volumes.
More importantly, you’ll learn how to configure LVM, starting with the pvcreate command to configure physical volumes, the vgcreate command to configure volume groups, and the lvcreate command to create logical volumes.
Plus, you’ll see how easy it is to extend file systems and logical volumes using the lvextend command. Likewise, adding more space to the storage pool is painless with the vgextend command.
Next, you’ll learn how to create mirrored logical volumes and even how to migrate data from one storage device to another, without taking any downtime.
