The goal of this document is to explain how to extend the root partition of an OCI Instance, the root partition is the last partition on the OCI Instances "/dev/sda3", when an OCI Instance is created using a custom boot volume with a bigger size than the default size, the partition table is only created using the default partition layout and the remaining space gets un_allocated, this is why the root partition needs to be resized to use the free space or either a new partition needs to be created to reclaim that free space.
This document is intended for the Linux instances, since this is a default behaviour for the OCI Instances.
