If you have multiple disks one core is STILL more than enough to handle the load. Remember this is only carls assertion that Reiserfs can't possibly handle multiple disks, because its all single thread in a single core of a single processor. Yet systems with dozens of disks work just fine with Reiserfs. In fact I've raid on riserfs partitions on 4 drives with zero performance problems. -- After all is said and done, more is said than done. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Of course they work. I have several disks with reiserfs. But run a load-speed-parallel-test-suite on the same multicore multidisk, machine, first with several huge reiserfs disks, then reformat as xfs, then reformat as ext4, then reformat as btrfs, and compare them all. You will see that resiserfs doesn't come out as fast as expected. And this is one of the things that R4 solves, I understand. Work? Yes. But not as perfect as it should: after all, it is about a decade old code that nobody maintains, even less update. Yes, nobody. Bug 460020 - External USB disk (encrypted, reiserfs) gets corruption. Bug 471382 - External USB disk (reiserfs) gets corrupted and becomes read-only. --> wontfix and duplicate. oS 11.0. Nobody looked at it (them), then it was closed automatically on release end, with the (useless) suggestion to reproduce in 11.3 or beyond. I had to reformat that hard disk to something else, of course. Bug 879778 - Kernel crash on multiple file write on reiserfs GPT partition. That one is on 13.1 (2014-05-24), and has not got a single comment from the maintainer - thus, there is no maintainer. Plain as that! If you intend to use reiserfs, you should seek out all the bugzillas and vote for them. Maybe they listen to you. Maybe not. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

Yea... I miss good old days when reiserfs was the fs of choice in most usecases. I wish they made Hans Reiser sit and work on it 16 hours a day as his community service, instead of cleaning highways. That would benefit much wider audience. -- Regards, Stas -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

LOL. Yes. On the other hand... what if he plants a code bomb, out of despise? (I don't approve of using inmates for any work, anyway, besides their own building maintenance and cleaning. It's slave labor, takes out real jobs from good people, and does not cure them of their "malignancy", probably worsens it. But this is not the place for that discussion). -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
