I want to give folks a status update on the illumos corporate entity. In a nutshell, the corporate entity seems to be failing to have traction.  In particular, the various corporate contributors  and downstreams for illumos have declined to step up to ensure that an illumos corporate entity has sufficient backing to make it successful. While at first blush, this seems somewhat unfortunate, I think this is not nearly quite as bad a thing as it might first seem.  In particular, the failure of a corporate entity does not correlate to the health of the ecosystem -- indeed many successful open source projects operate without an umbrella organization or entity.  Instead, we see corporate contributors and downstream distributions focusing on developing the communities behind their distributions such as SmartOS and OmniOS .  Those downstreams play an active role in improving illumos for the benefit of all, and its my sincere hope and belief that they will ...

I think illumos is at a key juncture, and the issue relates to our toolchain. We have gcc 4.4.4 working thanks in large part to the efforts of folks like Rich Lowe. We have historically relied on Sun Studio (now Solaris Studio) as our "base" or "default" compiler for C and C++ programs, and also to supply lint coverage. I've been thinking for a long time that its past time we (the illumos community) moved on from this.  Not only are the Studio 12 compilers not available in source form, they are now not available in suitable form for building illumos as binaries either.  (Apparently it is possible under some terms to get Solaris Studio 12.3, but who knows if those compilers are suitable for building illumos.  In the past we have always needed specifically patched compilers for Solaris.) The situation where a general developer cannot obtain the necessary tool chain for working with illumos is untenable. Today we require "lint" as part...

We have an... ahem... toxic personality in our midst in illumos .  I'm going to respond here to his most recent post , to avoid wasting the time on the illumos developers mailing list.  If you don't care about non-sense like this (although it may have entertainment value), please just ignore this post and move on. The only reason I'm replying even here, is to set the record straight, and establish firmly the history -- at least my side of it -- for posterity. In the early days of illumos, I invited those I could think of from the Solaris and OpenSolaris communities to participate.  I even reached out to some parties, like Jörg Schilling, who had a bad reputation as difficult people to work with. I had hoped to repair those broken relationships since there was no longer a corporate controlling entity for illumos.  ( Nexenta sponsored my efforts, and paid some of the early operating costs for illumos, but it has always been the case that illumos operates by and...

Yesterday, with very little fanfare, illumos passed an important milestone. This milestone was the integration of  195 Need replacement for nfs/lockd+klm This is work that I originally tasked Gordon Ross and Dan Kruchinin to work while we were colleagues at  Nexenta .  Gordon started the work, picking up bits from FreeBSD as a starting point and gluing it to the illumos entry points.  Dan continued with it, and fleshed out a lot of the skeleton that Gordon had started.  It was subsequently picked up by the engineers at Delphix , and -- after some important bug fixing work was completed -- was integrated into their product quite some time ago -- reportedly its been stable since December in their product. The reason this is such an important milestone, is two fold: First, this represents a substantial collaborative effort, involving contributions from parties across several organizational boundaries.  The level of collaboration achieved here is a w...

The ZFS code in illumos has gained another differentiator thanks to the hard work of Saso, who integrated LZ4 improved compression into our code base. This is a nice achievement, and enhanced compression should be quite useful for most applications of ZFS.  If LZJB was always recommended to be turned on (it was by our team at least!), then LZ4 is even more recommended, unless all of your data is totally incompressible.  (Most data is highly compressible.) You should check out his wiki post above, which contains a lot more details about the work, including some benchmark data.
