Cloning is very interesting from a speed to provision standpoint but is begging for trouble in the long term without deduplication to handle ongoing operation. -- Mike Gerdts http://mgerdts.blogspot.com/

What I can say, however, is that "open source" does not always equate to requiring "open development". I do not think that Jeff, Bill and team are trying to "prove" anything by "keeping their mouth[s] shut". I think you should remember that they have a heckuvalot on their plates right now, and deduplication is not an _easy_ problem to solve. It must be done Correctly, and I do not believe there is any wiggle room on that. Besides that, if you''re so worried about it, why haven''t you asked them directly? James C. McPherson -- Senior Kernel Software Engineer, Solaris Sun Microsystems http://blogs.sun.com/jmcp http://www.jmcp.homeunix.com/blog Kernel Conference Australia - http://au.sun.com/sunnews/events/2009/kernel
I don''t think this is anything unusual, nor suspicious. Sun have released huge amounts of code to the open source communities, and the very fact that you can come on these forums, ask a question like that, and get answers back from some of the kernel developers shows just how open Sun is. However, they are still a company in competition with others, they have a long history of internal development, and since the majority of Solaris development is contributed by Sun, I can see why they would keep things relatively quiet until they are nearing release. Why would they want to give all their competitors advanced warning of what they''re doing before it''s ready? -- This message posted from opensolaris.org
Hello James,> Hi Cyril, > I don''t work with Jeff and Bill, and I cannot speak for them > about this. > > What I can say, however, is that "open source" does not always > equate to requiring "open development".Indeed. However willingness to openly develop opensource project or lack of that of is also considered by community. Open source is much more than throwing the code over the wall. Heck, in the early pilot days I was told by a number of Sun engineers, that the reason things are taking time is exactly that - we do not want to just throw the code over the wall - we want to build a community.> I do not think that Jeff, Bill and team are trying to "prove" > anything by "keeping their mouth[s] shut".

So Jeff, Bill and team (I know you are on this list), is there any reason ZFS deduplication project isn''t run as OpenSolaris project ? With code repository, mailing list and all the other things publicly available. That way the development process becomes transparent and community members may contribute as well (if they choose/want to). -- Regards, Cyril

While the community may desire fresh, juicy source to dig through on a regular basis, it''s not always going to land in your lap. You can''t always get what you want. In this case, however, you will get what you need - the finished product. Finally, there is one rather simple way to pull development out into the open - write some relevant code and be part of the development process. If people delivered code as quickly as they deliver words, the development process would be wide out in the open. -- Andre van Eyssen. mail: andre at purplecow.org jabber: andre at interact.purplecow.org purplecow.org: UNIX for the masses http://www2.purplecow.org purplecow.org: PCOWpix http://pix.purplecow.org

Is there a public anouncement (from Sun) somewhere that there is a ZFS deduplication project or are you just speculating that there might be such a project? My own priority for ZFS development is that ZFS should not be 4X slower at accessing a file if it has been accessed (a long time) before, or 8X slower if it has been accessed (a long time) before and also mmap()ed. Other people have posted performance gripes about resilver times and zfs send. To me, getting existing features to operate in a stellar fashion is more important than adding new features.

If you''re fitting the bill for the development, then it''s your prerogative on how you want to proceed with openness IMHO. I wouldn''t mind some more information on these things for academic reasons, but I''m in no position to make depends.
Yup, that''s one feature I''m eagerly awaiting too, the list of things it could facilitate is huge. -- This message posted from opensolaris.org

BSD developers do this all the time not really meaning anything bad by it, but for CDDL or GPL both by law and by custom, you do ``testing'''' then you get to see source, period. * allow free enough access to the source that whoever gets it can fork and continue development under any organizing process they want. The organizing process for development is also worth talking about, but for me it isn''t such a clear political movement. Even the projects that unlike Solaris have always been open, where openness is their core goal above anything else, still benefit from openbsd hackathons, the .nl HAR camp, and other meetings where insiders who know each other personally sequester themselves in physical proximity and privately work on something which they release all at once when the camping trip is over. Private development branches can be good, and certainly don''t scare me away from a project the same way as intentional GPL incompatibility, closed-source stable branches, proprietary installer-maker build scripts, scattering of binary blobs throughout the tree, selling hardware as a VAR then dropping the ball getting free drivers out of the OEM''s, and so on. There are other organizing things I absolutely do have a problem with. For example, attracting discussion to censored web forums (which on OpenSolaris we do NOT have because here the forums are just extra-friendly mailing list archives plus a posting interface for web20 idiots, but many Linux subprojects do have censored forums). And PR-expurgated read-only bug databases (which OpenSolaris does have while Ubuntu, Debian, Gentoo, u.s.w. do not). There''s a second problem with GPL at Akamai and Google. Suppose Greenbytes wrote dedup changes but didn''t release their source, then started selling deduplicated hosted storage over vlan in several major telco hotels. I''d have a political/community-advocacy problem with that, and probably no legal remedy. -------------- next part -------------- A non-text attachment was scrubbed...

I definitely _do_ recall asking for people to be patient because (1) we had lighting problems with the auditorium which interfered with recording video (2) we have been getting the videos professionally edited so that when we can put them up on an appropriate site (which I imagine will be slx.sun.com), then the vids will adhere to the high standards which you have come to expect. (3) professional editing of videos takes time and money. We are getting this done as fast as we can. I asked Deirdre about the videos yesterday, she said that they are almost ready.
