Eurobsdcon 2019, Lillehammer, Norway [email protected] Summary & Introductions
The Future of OpenZFS and FreeBSD EuroBSDCon 2019, Lillehammer, Norway [email protected] Summary & Introductions Allan Jude Klara Inc. FreeBSD Core Team FreeBSD Professional OpenZFS Developer Services and Support Covered in this presentation OpenZFS Challenges Changing What does the Past, Present, Facing FreeBSD’s future hold for Future OpenZFS Upstream OpenZFS? The Evolution of ZFS ● ZFS was originally developed at Sun Microsystems starting in 2001, and open sourced under the CDDL license in 2005 ● Oracle bought Sun in 2010, and close sourced further work ● illumos, a fork of the last open source version of Solaris became the new upstream for work on ZFS ● ZFS was ported to many platforms, including FreeBSD in 2007 and Linux in 2008. The OpenZFS project was founded to coordinate development across platforms. OpenZFS ● The original plan for OpenZFS was a single common repository where the OS independent code would live and be tested ● Each OS would pull in this repo and maintain local glue bits ● However, the effort required to maintain a repo that would not be directly used by any of the consumers was too great ● The “repo of record” became a copy of the illumos repo, pull requests were carried through illumos’ RTI by Matt’s team ● FreeBSD tracked this repo very closely, commit by commit Platforms ● OpenZFS is now available on almost every platform ○ illumos (OmniOS, OpenIndiana, SmartOS, DilOS, Tribblix) ■ FreeBSD (FreeNAS, XigmaNAS, TrueOS, pfSense, etc) ● NetBSD ■ ZFS-on-Linux (Ubuntu, Gentoo, Proxmox, OviOS) ● Mac OS X (https://openzfsonosx.org/) ● Windows (https://openzfsonwindows.org/) ● OSv Divergence ● Each different platform’s version of ZFS started to diverge ● OpenZFS replaced the old “pool version number” with “Feature Flags”, since features would land in different orders ● Bugs were fixed in one repo and not necessarily upstreamed or communicated to other platform’s could apply the same fix ● Each camp did their development within their own community, and other communities might not be aware of duplicate efforts, etc. -
The Rise & Development of Illumos
Fork Yeah! The Rise & Development of illumos Bryan Cantrill VP, Engineering [email protected] @bcantrill WTF is illumos? • An open source descendant of OpenSolaris • ...which itself was a branch of Solaris Nevada • ...which was the name of the release after Solaris 10 • ...and was open but is now closed • ...and is itself a descendant of Solaris 2.x • ...but it can all be called “SunOS 5.x” • ...but not “SunOS 4.x” — thatʼs different • Letʼs start at (or rather, near) the beginning... SunOS: A peopleʼs history • In the early 1990s, after a painful transition to Solaris, much of the SunOS 4.x engineering talent had left • Problems compounded by the adoption of an immature SCM, the Network Software Environment (NSE) • The engineers revolted: Larry McVoy developed a much simpler variant of NSE called NSElite (ancestor to git) • Using NSElite (and later, TeamWare), Roger Faulkner, Tim Marsland, Joe Kowalski and Jeff Bonwick led a sufficiently parallelized development effort to produce Solaris 2.3, “the first version that worked” • ...but with Solaris 2.4, management took over day-to- day operations of the release, and quality slipped again Solaris 2.5: Do or die • Solaris 2.5 absolutely had to get it right — Sun had new hardware, the UltraSPARC-I, that depended on it • To assure quality, the engineers “took over,” with Bonwick installed as the gatekeeper • Bonwick granted authority to “rip it out if itʼs broken" — an early BDFL model, and a template for later generations of engineering leadership • Solaris 2.5 shipped on schedule and at quality -

Incorporating the Digital Commons:Corporate Involvement in Free and Open Source Software
INCORPORATING THE DIGITAL COMMONS DIGITAL THE INCORPORATING INCORPORATING THE CDSMS DIGITAL COMMONS he concept of ‘the commons’ has been used as a framework to understand resources shared by a community rather than a private BENJAMIN J. BIRKINBINE T entity, and it has also inspired social movements working against the enclosure of public goods and resources. One such resource is free (libre) and open source software (FLOSS). FLOSS emerged as an alternative to proprietary software in the 1980s. However, both the products and production processes of FLOSS have become incorporated into capitalist INCORPORATING THE production. For example, Red Hat, Inc. is a large publicly traded company whose business model relies entirely on free software, and IBM, Intel, Cisco, Samsung, Google are some of the largest contributors to Linux, the DIGITAL COMMONS open-source operating system. This book explores the ways in which FLOSS has been incorporated into digital capitalism. Just as the commons have been used as a motivational frame for radical social movements, it has also Corporate Involvement in Free served the interests of free-marketeers, corporate libertarians, and states to expand their reach by dragging the shared resources of social life onto and Open Source Software digital platforms so they can be integrated into the global capitalist system. The book concludes by asserting the need for a critical political economic understanding of the commons that foregrounds (digital) labour, class struggle, and uneven power distribution within the digital commons as well as between FLOSS communities and their corporate sponsors.

February 2015 Meeting Announcements
February 2015 Meeting Announcements OCLUG February Presentation 2015-02-05 2 OCLUG February Presentation 2015-02-05 3 Tarsnap ● Tarsnap is a secure online backup service for BSD, Linux, OS X, Minix, OpenIndiana, Cygwin, and probably many other UNIX-like operating systems. The Tarsnap client code provides a flexible and powerful command-line interface which can be used directly or via shell scripts. ● At the present time, Tarsnap does not support Windows (except via Cygwin) and does not have a graphical user interface. From the tarsnap home page http://tarsnap.com OCLUG February Presentation 2015-02-05 4 Tarsnap Design ● The design of Tarsnap was guided by the following four principles: – Security – Flexibility – Efficiency – Utility ● The website explains this in detail OCLUG February Presentation 2015-02-05 5 What it is ● An encrypted, deduplicated off-site block store with a tar like interface. ● An archive system – think of it more like a tape. ● Geared for servers and experienced sysadmins. OCLUG February Presentation 2015-02-05 6 What it is not ● A service like Dropbox or SpiderOak. ● A browsable offline collection. ● A file by file backup ● Geared to end-users ● Free OCLUG February Presentation 2015-02-05 7 Pricing ● The cost is based on byte storage and is calculated as 250 pico dollars/byte stored and the same for bandwidth. – By this math, 1TB of data will cost $250.00 to store per month. – On the other hand, 1GB costs $0.25/month – You only pay for transmission and storage, so if you are using less, you pay for less.
