Disk partitions are the basis of storing our data on disks. To be able to handle partitions, in this part of RHCSA exam preparation tutorial we will add an empty disk to our test RHEL 8 system, and create, list, and delete a new partition on it. First we will use the classic MBR (Master Boot Record) setup, then we'll do the same on GPT (GUID Partitioning Table) setup. GPT is a more advanced partitioning technique that allows large partitions, whereas MBR is limited to 2 TB disk space per partition. So if that doesn't seem like a very limiting size at the moment, think of the trend of disk usage, which may be not that much from the end user perspective, but certainly it is from the Linux system administration job perspective.
