Reiser4 File System Still In Development 317

Posted by timothy from the despite-it-all dept.
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?"

      What's also key is that the better points of ReiserFS, such as journaling, have migrated into other file systems. The experiment wasn't a failure, it was a darn good idea that has led to an overall improvement in reliability and speed of other file systems.

        I've been watching Btrfs and it feels like they're merging in most of the features Reiser had in mind without saying so explicitly. I've considered it a spiritual successor for a while now.

        Journaling is not the main attraction of ReiserFS. It's the validation of the million-small-file design. Why use a database? Why accumulate records in larger files? Just make every record a separate file (and Hans Reiser wanted to go even further down that path).

        Numerous software systems have employed the million-small-file approach. It is simple, natural, attractive. There are lots of handy shell utilities for ad-hoc scripts and other useful tricks.

        The ReiserFS was all about the namespace. We already have it in linux/unix. It's the file system namespace. It should be used to the fullest. Reading a small file should be as efficient as reading a line of a larger file.

        Screw SQL. All data should be amenable to grep, awk, perl, od, rm, mv, ln, sort, head, cut &co.

        • Very interesting. The stuff about large numbers of small files seemed silly to me until I read your post. Making the file system absorb the capabilities of a database is clever and would make a lot of things easier.

      Reiser4 was supposed to give us a different way of working with file metadata by making files into directories, was supposed to allow us to set different file permissions on every line of /etc/passwd, or maybe every field. All those features were dropped though, so what's the point now when other filesystems are further ahead in other areas?

      Yeah, it was so terrible that they had evidence rather than loony conspiracy theories like Hans and his defense attorneys were throwing out. He was not some person being prosecuted for being "weird" or other such nonsense that you defenders kept claiming. He was an emotional and physical abusive asshole who murdered his wife for having the 'audacity' to leave an abusive relationship. He deserves no sympathy.

The minute the evidence came out, it screamed "he totally fucking killed her!"

      I ran reiser3 for a long time. I was happy with it. But these days I'm on ext4 (and eyeing btrfs). Wonderful thing about btrfs and the ext* FS's is that they provided a migration plan. Reiser4 (at least last I checked) could not convert an existing FS (even reiser3). btrfs can even convert ext4 and allow you *TO GO BACK* if you want. How awesome is that?

    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.
