Formatting and mounting filesystems
In the previous section, we learned how to logically divide our disk, but that disk is still not usable for storing data. In order to enable this to do so, we need to define a filesystem on it as the first step to make it available to our system.
A filesystem is a logical structure that defines how files, folders, and more are stored and provides, based on each type, a different set of features.
The number and types of filesystems supported depends on the operating system version, as during its evolution, new filesystems might be added, removed, and so on.
Tip
Remember that Red Hat Enterprise Linux (RHEL) focuses on stability, so there are strict controls about which features are added or phased out for newer releases, but not within the current release. You can read more about this at https://access.redhat.com/articles/rhel8-abi-compatibility.
In RHEL 8, the default filesystem is the eXtended File System (XFS), but you can see a list...
