Here we will take a visit into the world of Linux and Logical Volume Management or LVM. Making the most of our storage by enabling it to a be flexible. The bottom of the food chain are physical volumes that represent storage. these are added to volume goups that make the space available to logical volumes. Being able to extend the volume grouip with additional disk storage from PVs that we add as needed enable us to extend the size of our logical volumes and ultimately or file-systems. We will look at pvcreate, pvscan, vgcreate, vgscan and vgextend, and of course, lvcreate, lvscan and lvextend in the course of the video.
