Reiser4 File System Still In Development
An anonymous reader writes "Reiser4 still hasn't been merged into the mainline Linux kernel, but it's still being worked on by a small group of developers following Hans Reiser being convicted for murdering his wife. Reiser4 was updated in September on SourceForge to work with the Linux 3.5 kernel and has been benchmarked against EXT4, Btrfs, XFS, and ReiserFS. Reiser4 loses out in most of the Linux file-system performance tests, has much stigma due to Hans Reiser, and Btrfs is surpassing it feature-wise, so does it have any future in Linux ahead?"
If you can find any name that's not related to murdering your wife, go for it. Bonus points if it's catchy.
One of the strneghts, and weaknesses, of the OSS community is trying bunches of things in parrell to see which ones pan out well. But after a point, it is probably better to just like a project die. Granted no one can tell the individual developers what is 'worth' their time since that is a personal matter, I am sure other projects could use their talents more then this one. ReiserFS is a solution looking for a problem where better solutions surpass it.
Would we even be bothered in following this kind of story if it weren't for the murder? If not than just let it go now.
There's going to be a few off color jokes. May as well get started.
* It's a killer filesystem.
* My disk died. Was ReiserFS the murderer?
* It's more cutting edge than Reiser's knife.

It would need a lot more configurable flags and useless values to tweak for us Gentoo folks to take it up. :-)

Sorry for being on topic. I remember discussing this on /. and I'm still kinda surprised Hans actually did it. I still think it was a bad conviction, even if it randomly happened to have turned out to be correct. Kind of like the salem witch trial convictions were wrong, even if we somehow figured out one of them was a real live magical genuine witch after the fact (however unlikely that would be).
Anyway, enough dr phil and now on to IT stuff:
1) Most benchmarks don't matter. Nobody makes money running benchmarks. Because the cost of casting up a production image is virtually (ha ha) zero because of virtualization SW and NAS stuff and puppet and some other tools, its well worth your while to spend an hour or two trying various instrumented FS to see which is fastest under your own workload, unless your workload is so stereotypical you can just rely on the hivemind opinion. Best of all if you can load balance on the FE then run multiple BE each with different FS and if applicable different FS parameters then watch how each FS actually performs under real live load. This is how REAL IT is done, as opposed to "I drunk me an energy drink and got a linux CDrom with this magazine and read me a slashdot article" style IT. I would not be surprised if somebody with some totally werido workload actually benefits off running reiserfs. Its a huge possible solution space and I'm sure it wins somewhere.
2) Check out the contents of something like /lib/modules/"somethin"/kernel/fs. Dude, I've got a minix module which I haven't used production since 1992 ish era (running minix of course). As long as someone, somewhere, has an old disk image from some historical whatever, someone's probably going to want computer archaeologist tools to look at the innards on a modern system. Admittedly for minix and maybe soon reiserfs, they might be better served by something like "mtools for reiserfs" than a kernel module or a FUSE solution, but if someone wants to do something in free software that you don't personally like, well good luck stopping them. Whaddya gonna do, change the license to something non-free just to stop them? Good luck!

On the bight side, Hans might have a 20 year all expenses paid development cycle ahead of him. Think of the contribution he could make if allowed to.

has much stigma due to Hans Reiser
Really? You can't just judge it based on it's features and performance?
So if Linus Torvalds ever commits a crime, you'll stop using Linux?
The murder scandal got the project waylaid long enough that everyone else moved on.
Even if the stigma that threw banana peels in the way is gone, reiser4 is still far behind.
If it's open source, cannibalize it and take the features.
Kidding aside and as a fellow Gentoo user, I've actually found a lot of those use flags have gone away and been replaced with high level feature level flags. I mean there are still the classics and my package.use is fairly long.. but it's definitely improved (or gotten worse depending on your viewpoint) in the last few years..
But let the team try to succeed, and maybe entice another high-grade mathematician into the project to boot. Any strangeness is exterior to the project despite the name, and there are plenty of advances we embrace despite the origins. Hypothermia studies, for example (in my junior high class they asked about the ethics of retaining knowledge obtained unethically.) Or Shockley, who invented the transistor but advocated eugenics later in life.
It's not pretty, but you cannot write off the contributions to science of someone -- or some group -- whose actions you might find abhorrent at some level. Wernher von Braun put the U.S. on the moon, like it or not. One act doesn't reduce an entire career to the trash heap.
There is no reason why a convict should be denied the tools and space to develop software when that software is in everyone's best interest. Even if it was some sort of nonsense app that would provide an income for a convict following release or just keep his skills up to par so that he had hope of earning a living upon release it would be in the public interest.
One of the main reasons for another conviction often relates to convicts being kept out of decent jobs when they are put on the streets. If people can not earn a living they don't just dry out like a worm on a sidewalk. A legal living made unavailable will steer them into crime, or cause drunken behaviors that lead to re-arrest.
If you can't change it, embrace it!
People always say X is the killer FS, no Y is the killer FS. Well, this one really is.
Dark humor aside, back in 2003-2004 in my university lab we were running a project that required processing of massive amounts of small files. I had trial runs over the linux file systems of the era and Reiser (I guess version 3 back then?) was so much faster in that context that it could actually save significant processing time. So it I always thought it a real shame that the main developer committed murder and development pretty much stopped back then. Yeah, there are now faster and better FSs, but perhaps Reiser would be a great option as well.

Einstein did invent the atomic bomb, didn't he...?
LOL no that's not really his thing. It was a big physics project and he was a physicist some decades before Trinity, but that's about as much connection as exists.
Its like asking who invented the computer (or the internet), the real invention is the very twisty logic required to narrow it down to only and exactly one person.

Lack of knowledge is so sad. One has only to have a passing understanding of data models to read Reiser’s paper and realise he
does not understand the fundamental concepts of the field. Such a waste of time, money and talents.

No. next question
I stopped using ReiserFS long before it's namesake was arrested. It used to lose data. That's pretty much a showstopper for a filesystem who's claim to fame was reliability.

The bottom of the first page in Phoronix's benchmarks says "The disk drive being used for all testing was a high-end 160GB Intel SSD." Since different filesystems are optimized for different things, it seems such benchmarks could be completely irrelevant for anyone using hard drives (where seek times are very significant compared to SSD).
The murder of his wife was the straw that broke the camel's back, but for me, I started turning away from Reiser based on the sliminess of the Burke character he played in "Aliens". Of course, that "Mad About You" shit didn't help much, either.

Einstein didn't even get security clearance to work on the Manhattan project because he was a pacifist.
There were about 10 000 scientists working on the Manhattan project, but if I had to name the inventor of the atomic bomb, I would say it was Leo Szilard.

Einstein did invent the atomic bomb, didn't he...?
No. Einstein's threory was necessary for its invention, but the primary guys were Niels Bohr and Enrico Fermi. In 1934 the idea of chain reaction via neutron was proposed by Leó Szilárd, who patented the idea of the atomic bomb (British patent 630,726). See wikipedia.

We know from experience that hidden files won't stay hidden for long. A little coersion and it confesses everything--all in hopes that it won't get reformatted.
Everyone else has already said no, but I would like to point out that there is a grain of truth to that statement. . . Einstein's signature on a letter to FDR was the impetus for the Manhattan Project - he was concerned that the Nazis would develop a nuke first.

No, no he fucking didn't.
of an acclaimed FS is on the horizon and we laugh at its creator who murdered his wife. Im not sure how it works in other countries, but in America the prison system is just another device for enacting biblical retribution. Hans isnt seeing any treatment for his actions, rather hes spending 15 years to life in prison.
Depending on your personal conviction to things like the death penalty and crime in general, you could consider the man who brought you a glorious experiment, ReiserFS, is a sick man. He's been taken to the cleaners for 60 million in a wrongful death suit, which is said to go to "the kids" but seriously sounds like it was orchestrated by their grandmother. After the trial he insisted the attorney forced him to take the stand, and afterwards served as his own attorney. Hes repeating the same delusional actions of self representation he did during the original trial, and no one considers this a manifestation of an illness.
if none of this makes any sense and you're still subscribed to the idea that prison was the best solution for this man, then you can revel in the computer chair justice of knowing he was brutally assaulted by several prisoners in 2009. The DOJ's solution, not to rehabilitate or anything, was simply to shuffle what amounts to another cash cow to another farm. he is currently in Pleasant Valley state prison.

By the time you are considering using an atomic bomb, I guess being sued for patent infringement is the least of your concerns.

You may want to tone down your sensitivity for this one, it was not serious.
I believe what sealed it in the end was that he eventually led them to the body in return for more lenient sentence. Pretty hard to argue his innocence after that.
I believe the next big thing is ZFS. My paranoid side reads these articles about how disk error rates are staying about the same, but disk capacities are going up and up. I'm thinking that ZFS and anything else that can verify the reads / writes sucess is a very good thing moving forward.
Likewise, if Reiser had killed his wife out of legitimate concern that otherwise she would kill him, he wouldn't be in jail now.
No! don't re-integrate it, it's cursed!

I think the fact that he confessed to killing her and then proceeded to lead police to her body is a pretty good indication of his guilt: http://www.sfgate.com/bayarea/article/Reiser-confesses-to-strangling-estranged-wife-3197731.php
File system corruption on that system means wiping and staring again - there's no fsck to fix minor errors. The reason given for this lack was that it was a perfect system, which is no help at all if it's not running on perfect hardware.
It's a proof of concept system that is not yet designed for use in any situation where the contents of the data stored on the file system actually matter.
It doesn't even have fsck and that delay was from replaying a portion of the journal. There's nothing wrong with that, ext* does that too, but it did seem to be almost as slow doing it as ext* takes with a full fsck a couple of times a year.
Until that point the evidence that had been reported to the public was very slim, and there had a lot of very strange and confusing reports due to some of the suspicious people he associated with that ultimately turned out to be irrelevant noise.
OK then - instead of calling people names (ie. spreader of fear, uncertainty and doubt - think you need a different insult for the merely ignorant) for not keeping in touch with changes to what we all assumed was a dead project for the past few years how about letting us know how long ago it came in? I can't tell from that link on your other post and had incorrectly assumed that the messy dd method was still the only hope. If I mucked about with that stupid waste of time for no reason a few years back I'm going to feel very silly.
--Sorry bout that; it's just the way you came across. Personally, I had only a vague idea that Reiser4 was still in semi-active development until I saw this Slashdot headline.
--I did come up with a few links, but as for when $bug was fixed in Reiserfs, you would prolly have to search the kernel mailing lists or the project's home page.

== WolfriderV6 == I'm willing to admit that *I just might* be wrong... Are you??
Thanks for that. I only ever saw Reiserfs when it failed so I'd say I have a skewed impression on it. One of the more trendy than stable linux distros had Reiserfs as it's default some years ago when it was still in a state of rapid change, and a few people at my workplace put it on laptops. Combine beta software with less than perfect drives and frequent power loss (laptops running out of charge) and it's a pretty tough situation for a filesystem. The nail in the coffin was a lot of files of a size the file system couldn't handle very well at that point (I can't remember if they were multi-GB sizes files or thousands of 1k ones - R&D had situations with both), especially if the user let the thing lose power and it had to slowly replay it's journal on startup with that file size the filesystem wasn't designed to handle well at that point. We never actually lost anything worth recovering, but it was a pain at times.
Maybe I should give it another look, but I'm one of those types that's not even going to use btrfs or a linux zfs system yet on anything where I can't tolerate losing a days worth of new files.
