In August 2007, Apple opened a ZFS project on their Mac OS Forge web site. Before the 10.5 release, Apple released the 'ZFS Beta Seed v1.1', which allowed read-write access and the creation of zpools however, the installer for the 'ZFS Beta Seed v1.1' has been reported to only work on version 10.5.0, and has not been updated for version 10.5.1 and above.

In the release version of Mac OS X 10.5, ZFS was available in read-only mode from the command line, which lacks the possibility to create zpools or write to them.

However, the April 2016 release of Ubuntu 16.04 LTS includes CDDL-licensed ZFS on Linux as a kernel module that is maintained as a separate project, outside the Linux kernel mainline, claiming license compatibility.

As a workaround, FUSE, a framework that allows file systems to run in userspace, was used on Linux as a separation layer for which the licensing issues are not in effect, although with a set of its own issues that include performance penalty.

2016: Ubuntu 16.04 includes the open-source ZFS file system variant by defaultĪs the FSF claimed a CDDL and GPL legal incompatibility in 2005, Sun's implementation of the ZFS file system wasn't used as a basis for the development of a Linux kernel module, it wasn't merged into the Linux kernel mainline, and Linux distributions did not include it as a precompiled kernel module.

New features and fixes are regularly pulled into OpenZFS from illumos and pushed into all ports to other platforms, and vice versa.

2013: Official announcement of the OpenZFS as an umbrella project.

2013: The first stable release of ZFS on Linux.

2013: Coexisting with the stable version of MacZFS, its prototype generation (known as OpenZFS on OS X or O3X) uses ZFS on Linux as the new upstream codebase.

2012: Feature flags were introduced to replace legacy on-disk version numbers, enabling easier distributed evolution of the ZFS on-disk format to support new features.

Ports of ZFS to other platforms continued pulling in upstream changes from illumos.

2010: illumos was forked from OpenSolaris as its open-source successor, and continued to develop ZFS in the open.

2010: OpenSolaris was discontinued, resulting in the further development of ZFS on Solaris being no longer open-source.

2009: Apple's ZFS project closed, and the MacZFS project continued to develop the code.2008: Development of a native ZFS Linux port started, known as ZFS on Linux.2008: A port to FreeBSD was released as part of FreeBSD 7.0.

2007: Apple started porting of ZFS to Mac OS X.2006: Development of a FUSE ZFS port for Linux started.

2005: ZFS source code was released as part of OpenSolaris.

2001: Closed-source development of ZFS started with two engineers at Sun Microsystems.

The following is a list of key events to the development of ZFS and its various implementations, leading to the creation of OpenZFS as an umbrella project: : 6, 15 The ZFS source code was released in 2005 under the Common Development and Distribution License (CDDL) as part of the OpenSolaris operating system, and it was later ported to other operating systems and environments. The ZFS file system was originally developed by Sun Microsystems for the Solaris operating system. See also: History and implementations of ZFS The merged code-base will include a number of new features and performance enhancements, and is proposed to be known as OpenZFS 2.0. As of 2019, OpenZFS (on some platforms such as FreeBSD) is gradually being pivoted to be based upon ZFS on Linux, which has developed faster than other variants of OpenZFS and contains new features not yet ported to those other versions. The OpenZFS project is an open source derivative of the Oracle ZFS project. įounding members of OpenZFS include Matt Ahrens, one of the main architects of ZFS. The OpenZFS project brings together developers from the illumos, Linux, FreeBSD and macOS platforms, and a wide range of companies via the annual OpenZFS Developer Summit. It includes protection against data corruption, support for high storage capacities, efficient data compression, snapshots and copy-on-write clones, continuous integrity checking and automatic repair, encryption, remote replication with ZFS send and receive, and RAID-Z. OpenZFS is a CDDL licensed open-source storage platform that encompasses the functionality of traditional filesystems and volume manager.
