Welcome to OpenZFS

OpenZFS is open-source storage software which encompasses the functionality of traditional filesystems, volume managers, and more. Our community brings together developers from the illumos, FreeBSD, Linux, and MacOS platforms, and a wide range of companies and organizations. By working together, we will continue making OpenZFS an outstanding storage platform, with consistent reliability, functionality and performance across all distributions.

History

ZFS was originally developed by Sun Microsystems for the Solaris operating system. The source code for ZFS was released under the CDDL as part of the OpenSolaris operating system, and was subsequently ported to other platforms.

The illumos project was founded as an open source fork of OpenSolaris.

OpenZFS is the truly open source successor to the ZFS project. Development thrives as a part of illumos, which has added many features and performance improvements. New OpenZFS features and fixes are regularly pulled in from illumos, to all ports to other platforms, and vice versa.

Milestones

• 2001: Development of ZFS began
• 2005: release of source code for ZFS
• 2006: first alpha release of FUSE-based ZFS support for Linux
• 2007: Apple began an open source ZFS project
• 2007: FreeBSD 7.0 with native support for ZFS
• 2008: the ZFS on Linux project began development of a native port to Linux
• 2009: Apple's project closed; the MacZFS project continued to develop the code
• 2010: Oracle discontinued OpenSolaris; no further open source updates to ZFS on Solaris
• 2013: alongside the stable version of MacZFS, ZFS-OSX uses ZFS on Linux as a basis for the next generation of MacZFS
• 2013: the first stable release of ZFS on Linux
• 2013: OpenZFS

Goals

The main technical goal of the OpenZFS project is to make it easier to share changes between platforms. We have a number of efforts toward this:

• Creating a platform-independent mailing list for ZFS developers to review ZFS code and architecture changes from all platforms.

• Smoothing the illumos integration process.

• Making it easy to run both ztest and the ZFS test suite (TestRunner or STF based) on every platform.

• Reducing code differences between the platforms.
