Reiser FS: The open source file system fallout

Filed under
Reiser

Yesterday, the Open Source community took an emotional hit when veteran Linux programmer Hans Reiser was convicted of first degree murder in the suspicious disappearing of his wife, Nina. While I won’t go into the details of the case, as this has been covered extensively in the press, I would like to talk a little bit about how this verdict will impact the technology in play for file system dominance in our favorite Open Source operating system, Linux.

While Namesys’ ReiserFS, of which Hans Reiser (right) was the primary programmer and lead designer was not the pre-dominant journaled file system used on Linux systems, it was praised for its stability and performance, and was and still is the default file system on the second most popular enterprise Linux distribution, SuSE Linux Enterprise Server (SLES). ReiserFS was also included in the “upstream” Linux kernel maintained by Linus Torvalds because it shares the same license, GPL version 2. ReiserFS is also popular on Debian-based systems as well.

SuSE and Debian use ReiserFS version 3, a stable and proven version of the code that has been sitting mostly fallow for some time, and is maintained with bug and security fixes on a best effort basis. Prior to the whirlwind and highly publicized trial, Hans Reiser and his small team were working on Reiser4, but much of this development ground to a halt due to his legal woes, and the project is more than likely to die an unfortunate death by virtue of its lead programmer having to serve a minimum 25 year life sentence in prison.

From the SuSE and Debian perspective, this is an obviously unacceptable state of affairs.

  • For now, the future of ReiserFS, and its parent company Namesys, remain in jeopardy. Reiser put the company up for sale in December 2006, and as of yet the company is unsold. Namesys employee Alexander Lyamin, writing in the Linux Kernel Mailing List in December 2006, said his company will continue its work absent of Reiser’s leadership, and attempt to appoint a “proxy” to run operations until a better solution could be found. At this time, Namesys’ website is current inaccessible.

    "Misunderstood" programmer receives 25-to-life

  • The few prominent Linux distributions that were still shipping the stable version of ReiserFS by default have shifted to the more common Ext3 for various technical reasons. Reiser4, his next-generation filesystem, has been under active development for some time, but has not been streamlined into the Linux kernel because Linux developers claim that it fails to adhere to coding conventions and has several technical problems.

    Hans Reiser is fscked: jury delivers guilty verdict

  • I don’t know if Hans Reiser, creator of the well-regarded, open-source ReiserFS (Reiser File System), is actually guilty of the murder of his estranged wife, Nina Reiser. We can’t actually even be sure that Nina Reiser was murdered. Her body was never found and Reiser’s attorney argued that she may have returned to her native Russia.

    Never-the-less, as Wired reported, “with no body, no crime scene, no reliable eyewitness and virtually no physical evidence” Hans Reiser was found guilty of first-degree murder. In California, first-degree murder must be “willful, deliberate, and premeditated.”

    I don’t see it.

    Was Reiser really found Guilty of being a Hacker?

  • Computer programmer Hans Reiser was arrogant while testifying in his murder trial and never showed any compassion for his estranged wife, one of many factors that led to his conviction on first-degree murder, a member of the jury said today.

ReiserFS

Isn't one of the PRIMARY arguments for OPEN SOURCE suposed to be that it's "Open"?

Since ALL of the source is available, why does the fact that one programmer will no longer be working on it, doom the project?

So much for the great benefit of having ALL the source to prevent being burned by orphaned/abandoned/obsolete projects.

Re: ReiserFS

If you look up the history of ReiserFS, you'll indirectly notice the politics goes a lot into those things.
Even if Hans never got convicted or if reiserfs development continues, Reiser4 will never get integrated into the mainline kernel.

So, Hans will have 25 years perhaps in prison with nothing to do but to perfect Reiser4 or v5. However, the problem is that Reiser file system is reaching a dead end. Only defragmentation technology can be picked up to be added in ReiserFS v5.

I doubt they will give him a Linux desktop in jail lol.

A ReiserFS Without Hans Reiser

When an open source project loses one of its core people, it can be tough to pick up the pieces -- not just in terms of replacing that person's programming expertise or insight, but also to restore lost morale. On the plus side, the nature of an open source project does balance things out, if only in an opportunistic fashion.

Patches for the file system are still being submitted, as evinced by the traffic on the reiserfs-devel mailing list, and the folks at kernel.org have offered space to host the ReiserFS sources, giving it that much more of a lease on life. But without Reiser, I suspect ReiserFS itself is doomed -- or is at least due for a name change.

ReiserFS project death

Does the survival and development of the Reiser FS really matter? With the stability of ext3, XFS, and JFS, and the promised scalability of the developing ext4 and Btrfs, neither Reiser3 or Reiser4 seem needed.

I'm certainly no expert on file systems, but I found a filesystem partitioning combo years ago that has been extremely reliable for me, which does not include a Reiser FS partition.

Reiser4 might have become a great Linux filesystem, but so might others.

Leaked videos, screenshots reveal an HTC One running Android Lollipop

No, you won’t get this gift in time for Christmas, but perhaps seeing an HTC One running Lollipop may make the wait slightly less painful. A batch of videos and screenshots show HTC’s flagship with the newest build of Android, though of course it’s merged with the Sense 6.0 user interface (the HTC One currently runs Sense 5.0). We got a small hint of how Lollipop looks on the One in November, but this leak lays out what the entire operating system makeover looks in clearer detail. Read more

The winning Linux kernel live patch: All of the above

Life's choices often amount to one of two options: Linux or Windows? Android or iOS? Kgraft or Kpatch? That last pair consists of the two major contenders for the technology Linux could use for live kernel patches. Now a winner is in, and it amounts to all of the above. According to a post on the official Linux kernel developer's mailing list, a kernel patching system that works with both Kgraft and Kpatch and uses "core functionality abstracted out of [those] already existing implementations" has been proposed as an addition to the Linux 3.20 kernel.

UNIX Industry Banks on Linux Strategies

Struggling UNIX server makers are strengthening their Linux strategy in line with the open-source application environment. The move is aimed at maintaining remaining customers, since users are increasingly abandoning UNIX servers. However, it is receiving a lukewarm response from the market. According to industry sources on Dec. 22, server vendors such as IBM and HP are concentrating on the development of products so that the Linux operating system and related applications can be used as UNIX servers.

Mageia Beta Delayed, Christmas Quiz, and 7 Best Alternatives

Today in Linux news the Mageia project announced another delay in version 5 Beta 2. The Linux Voice is running a Linux quiz for Christmas and Gary Newell offers up his list of the seven best alternative Linux distributions of the year. The Register says 2015 will be the year of Linux - on mobile. Three reviews need to be highlighted and, finally today, Matt Hartley says everyone should switch to Ubuntu MATE.
