ZFS File System on Linux Ubuntu and Its Key Advantages

We will discuss ZFS file system, its structure, peculiarities, and downsides.

ZFS or Zettabyte File System is a special file system initially created by Sun Microsystems for the operating system called Solaris. It supports huge amounts of data, combines the concepts of a file system, physical disk and volume manager, and offers simple management methods for storage volumes.

It is a next generation file system initially designed for NAS solutions with improved security, reliability and performance. Unlike many other systems, ZFS is a 128-bit file system offering a virtually unlimited capacity. ZFS is an open-source project licensed under CDDL (Common Development and Distribution License).

If you want to use ZFS out of the box, you’ll have to install either FreeBSD or an operating system using the illumos kernel (illumos is a fork of the OpenSolaris kernel).

If you want to use ZFS on Ubuntu, you need to add the support features manually - but that’s a pretty easy thing to do and it involves running a few commands. We will explore it in detail a bit later, but now let’s talk about pros and cons of this file system.
