Hans was a genius, and a nut. Sometimes they come as a package. The claim was his wife used him for a green card and he flipped when he found out. But she also had his child, crazy how things turn out. Apparently he went out and bought a book on how to get away with murder and paid on his credit card right after, which is fairly revealing on a few levels. But at the time reiserFS was an astonishing feat of engineering and by a mile the best filesystem linux had
- snvzz 4y agoReiserfs was pretty good, at the time. At one point, it got nerfed by Linux maintainers introducing bad changes against Hans' advice, resulting in damage to the filesystem reputation. But Reiser4, which never got merged, was insane levels of amazing in latency and ops/second, and yet excellent in throughput still. Reiser4 was a team effort, and the other participants have been maintaining it irrespective of Reiser's imprisonment. Today, there are some legitimately non-crap filesystem efforts, but they are either not mainlined and not very active (Tux3) or not Linux (Hammer2 from Dragonfly). XFS could be made less crap; The main complaint I remember from Hans (dentries shouldn't be packed with inodes) does still stand. Metadata work such as a simple ls on a non-cached directory taking forever and a day. I am most hopeful that when Matt Dillon declares Hammer2 done, porting efforts will make it widespread in open source operating systems.
- realitylabs 4y agoI’m at best a layman when it comes to file systems, would you explain what makes Hammer2 so interesting comparatively?
