![]() In 2013 a group of developers initiated the OpenZFS project to help coordinate development efforts and avoid code fragmentation. The ZFS portion of the code was successfully ported to multiple open-source Unix-based OS platforms such as FreeBSD and macOS. Developers quickly forked OpenSolaris and the illumos OS was created to replace it. But by that time the source code has already been open for a good while. Initially, ZFS was closed-source, but in 2005 Sun Microsystems opened the source of its Solaris OS (which included their ZFS code-base) under a GPL license and the OpenSolaris OS was born.Ī few years later Oracle bough Sun and closed the source again.

To escape making these articles lengthy, we embed the links to many of the references in the technical terms we use. We aim at giving you some concentrated and easy to grasp information on how OpenZFS and TrueNAS work under the hood, how to build your TrueNAS server to take advantage of OpenZFS potentials, and the most common pitfalls you should avoid. In these articles we try to give a brief introduction to OpenZFS, and to TrueNAS CORE ®, the most popular solution built around it – by iXsystems. ![]() A brief history of OpenZFS and TrueNAS CORE ® ![]()
