ZFS is a file system focused on storage and redundancy. It's designed with file servers in mind, where high availability and data integrity are absolutely paramount. That's one reason it's interesting, but very exciting, to see it natively available on a desktop operating system like Ubuntu. Note that ZFS on Ubuntu is a new feature and therefore still flagged as "experimental."

The newest iteration of Ubuntu, Ubuntu 20.04 Focal Fossa, offers a new option during installation that hasn't been present in previous LTS releases. We now have the ability to format drives with the Z File System (ZFS) inside the Ubuntu installation process. Ubuntu itself still uses the ext4 file system, but the rest of your partitions or hard drives can be formatted with ZFS.

In this tutorial, we'll guide you through installing Ubuntu 20.04 with ZFS as our file system on a few drives. If you already have Ubuntu installed and aren't yet using ZFS, there's no need to do a fresh install. We'll show you how to install ZFS on an already established Ubuntu 20.04 install as well.

Webmin is an everyday tool for the sysadmin who would rather not leave his or her browser. It provides an all-in-one tool to manage your Linux box without the need to open a console. From backups to clustering, filesystems and system update, many aspects of your system is only a few clicks away with this compact tool.

In this tutorial we will install the latest stable Webmin to a freshly installed Ubuntu 20.04 system. It is a nice characteristic of Webmin that it does not really care if this distribution's release only came out a few days back, it does have a package for it, and it does install and run on it without any issues. To test this tool's capabilities, we'll perform a full system update of the operating system using the WUI (Web-based User Interface).
