Extending the capacity of the filesystem

CentOS 7 uses the Logical Volume Manager (LVM) to organize the structure and available capacity of your partitions. It is a very dynamic and flexible system that can be extended or rearranged over time, and which is essential in today's most demanding and ever-changing environments. At the moment, buzzwords such as big data or cloud computing can be heard everywhere. Since massive amounts of data get produced all the time, storage requirements and disk space have to grow at the same steady pace. In this recipe, you will learn how to work with the LVM system and how to extend your physical drives, and also how to shrink and extend the capacity of your filesystems.
