"Oracle today announced Oracle Solaris 11.1, delivering over 300 new performance and feature enhancements to the Oracle Solaris 11 product family." This stuff goes way over my head.
Sun Solaris, OpenSolaris Archive
If you have ever administered Sun machines, updates were a big part of your work. In the past, information about them were available on SunSolve, the Sun support website, to help sysadmins sort everything out. SunSolve has been decomissioned by Oracle and its replacement hasn't received a warm welcome from the Solaris community due in large part to technologies used (Flash,...). We Sun Solve was created to avoid this problem.
The OpenIndiana project has been officially announced. OpenIndiana is part of the Illumos foundation and a community distribution which aims to to continue OpenSolaris, previously shut down by Oracle. Some details of the announcement were published on c0t0d0s0.org.
The OpenSolaris governing board fell on its collective sword Monday and resigned en masse after Oracle continued to ignore its ultimatum to appoint a liaison guy to work with it on the future of the open source project. The move was anticlimactic to say the least. Oracle last week leaked an internal e-mail into the wild effectively saying OpenSolaris is dead. The news of the mass resignation, coupled with Oracle suing Google claiming Android infringes on its Java patents, had Adobe's director of open source and standards David McAllister casting Oracle as the New Microsoft and saying "the axis of evil has shifted south about 850 miles or so".
The Nexenta Core Platform marches on with the release of version 3.0 of the OpenSolaris based distribution, based on b134. It has also officially unveiled plans of moving from OpenSolaris to Illumos, the fully open branch of OpenSolaris. It will also now plan on moving to a new userland release. Grab the iso here.
Well, Oracle went from one of those big enterprise-serving companies most of us don't deal with to one of the more hated companies in our little community. Not only did they just sue Google over Android and its use of Java-related technologies, they also just officially killed off OpenSolaris. Solaris will still be open source, but source code will only come after each major release - development will happen behind closed doors.
Due to me not working for OSNews these past eight weeks, I've been a bit out of the loop, as I didn't really follow technology news. I did notice that a lot is going on in OpenSolaris land, and today, Oracle has outlined what it has planned for Solaris 11 - and according to some, the fears about OpenSolaris' future were justified.
A recent vague announcement on osol-announce hints that something big is rumbling for OpenSolaris: "A number of the community leaders from the OpenSolaris community have been working quietly together on a new effort called Illumos, and we're just about ready to fully disclose our work to, and invite the general participation of, the general public." They have a website, and they're going to be hosting a conference call on August 3.
Oracle has announced that rival hardware vendors Dell and Hewlett-Packard intend to certify and resell its Solaris and Enterprise Linux operating systems as well as Oracle VM on their x86 servers. The announcement "demonstrates Oracle's commitment to openness," company co-president Charles Phillips said in a statement.
A Computerworld blog speculates that the open-source Unix distribution may live on, but Oracle won't be supporting it. At this point, "OpenSolaris' only real future is as a fork, which would not be easy to pull off. Still, with enough interest from developers it could be done. OpenSolaris is licensed under the
GPLv3 CDDL and various other OSS licenses, so the base code is available."
This morning, at the OpenSolaris Governing Board (OGB) meeting, the following was proposed and unanimously resolved: "The OGB is keen to promote the uptake and open development of OpenSolaris and to work on behalf of the community with Oracle, as such the OGB needs Oracle to appoint a liaison by August 16, 2010, who has the the authority to talk about the future of OpenSolaris and its interaction with the OpenSolaris community otherwise the OGB will take action at the August 23 meeting to trigger the clause in the OGB charter that will return control of the community to Oracle."
Pavel Heimlich has announced the release of an updated version of Korona 4.4.3: "Korona is the live DVD adding KDE4 packages on top of OpenSolaris. It is intended to be the showcase of the current state of the kde-solaris project, definitely not a distribution for any serious use."
Frustrated by Oracle's delay in releasing the latest version of OpenSolaris, the OpenSolaris Governing Board is growing uneasy over Oracle's lack of communication regarding the future of the Unix OS code. At least two members of the board have even said they would be open to forking the code base from the Oracle version.
It appears that Oracle has lost interest in supporting the Solaris port for IBM SystemZ machines: "The SystemZ port of Solaris is dead. Oracle pulled all plugs and refused to further help the authors." In two years, the project has been downloaded only 1000 times.
"Hot on the heals of Oracle's revamp of Solaris support, the licensing agreement for free downloads of Solaris 10 have changed. Here is the bit in question: "...Please remember, your right to use Solaris acquired as a download is limited to a trial of 90 days, unless you acquire a service contract for the downloaded Software". So far the OpenSolaris license has not changed, it's still CDDL."
The NexentaStor project has released version 3.0 of the NexentaStor Community Edition. Based on the Nexenta Core Platform, the CE release is targeted at the home storage user. With its feature set of easy to use, ZFS based features like multiple raid configurations, inline deduplication, compression, integrated search, many plugins, it is a feature-rich gratis storage distribution. Grab iso and VM images from here. Release announcement is here.
Parallel NFS (pNFS) is a part of NFS 4.1 standard than allows NFS access in parallel. The Nexenta Project has released the very first distribution with pNFS support (integrated with the ZFS filesystem). Get the NCP-pNFS Experimental release here, and setup instructions here.
"There is a discussion at osnews.com about a simple question: "Should ZFS Have a fsck Tool?". The answer is simple: No. I could stop now, as this answer is pretty obvious when you work a while with ZFS, but i want to explain my position. And i want to ask a different question at the end."
ZFS has received built-in deduplication. "Deduplication is the process of eliminating duplicate copies of data. Dedup is generally either file-level, block-level, or byte-level. Chunks of data - files, blocks, or byte ranges - are checksummed using some hash function that uniquely identifies data with very high probability. Chunks of data are remembered in a table of some sort that maps the data's checksum to its storage location and reference count. When you store another copy of existing data, instead of allocating new space on disk, the dedup code just increments the reference count on the existing data. When data is highly replicated, which is typical of backup servers, virtual machine images, and source code repositories, deduplication can reduce space consumption not just by percentages, but by multiples."
One of the advantages of ZFS is that it doesn't need a fsck. Replication, self-healing and scrubbing are a much better alternative. After a few years of ZFS life, can we say it was the correct decision? The reports in the mailing list are a good indicator of what happens in the real world, and it appears that once again, reality beats theory. The author of the article analyzes the implications of not having a fsck tool and tries to explain why he thinks Sun will add one at some point.
