= Welcome to OpenZFS =

OpenZFS brings together developers and users from various open-source forks of the original ZFS on different platforms and we're always looking to grow our community. There are a multitude of ways to contribute to the project and contributors are happy to help newcomers. As we add diverse perspectives, our community becomes richer, and we're committed to creating an environment where all people feel welcome. Information for new contributors is available here.

Summary
OpenZFS was announced in September 2013 as the truly open source successor to the  ZFS project. Our community brings together developers from the illumos, FreeBSD, Linux, OS X and Windows platforms, and a wide range of companies that build products on top of OpenZFS.

OpenZFS is an outstanding storage platform that encompasses the functionality of traditional filesystems, volume managers, and more, with consistent reliability, functionality and performance across all distributions:

Goals
The high-level goals of OpenZFS are:
 * to raise awareness of the quality, utility, and availability of open source implementations of ZFS
 * to encourage open communication about ongoing efforts to improve open source ZFS
 * to ensure consistent reliability, functionality, and performance of all distributions of ZFS.

The main technical goal of OpenZFS is easier sharing of code between platforms. Strategies include:
 * creating a platform-independent mailing list for 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 each platform
 * reducing code differences between the platforms.
