Well, I finally got the time and the extra hard drive to do this, and XFS is now gone from my system. Running Reiser now, since I'm a speed fiend.

Nice to have a (hopefully) stable system again.


how much of a speed increase does Rieser give over ext3 ...?????

Don't know. I've never run it, and I rarely bother with benchmarks. All I know is, everyone says it's faster.

I don't have benchmarks either, but ReiserFS is faster than ext3.

So are you guys telling me that when my geforce arrives (should be in a matter of minutes now, before 5pm :) ), and I merge the nvidia drivers it will be completely bloody useless with my preemptable kernel?

Oh shit.

But if you have a cdburner, broadband, and a little time I would suggest using the knoppix live cd as you can't get much better than a rescue disk that can run kde or gnome :D

Just booted with Knoppix. That is truly amazing. It found and initialized /all/ my hardware without a single glitch, including the sound and video cards.

I'm keeping it around to use as my recovery CD. :D

I guess I'm confused :? . . .

I am running the current Gentoo-sources, and it already has xfs (I know it does because I'm using it) and preemt (again, I'm using it). What advantage(s) would one be looking for by hand-rolling the patches into vanilla-sources rather than just using the Gentoo-sources?

I was hoping to try and get them to work /nicely/ together. Unfortunately, that seems impossible at this time. XFS and Preempt are mutually exclusive, if you are concerned with stability. I'd recommend reiser as a substitute for XFS.

People are concerned with ReiserFS corruption -- XFS has corrupted on me one time after a week, ReiserFS has corrupted on me zero times after ten months (combined over three machines). I've found ReiserFS to be faster, too. I'm also using it with the preempt patch right now, with no issues.

Seriously, if you're doing a new Gentoo install, try out ReiserFS.

Do you not find ReiserFS slows once the disk is near full (1 Gig or less), seems I need to do some more testing to gather conclusive evidence on that one.

That's possible. It uses a hash to index the files, and with large numbers of files, it starts getting hash collisions, which would slow things down a bit.

Do you not get all those "foo-application exited with a preempt count of"?


As I said, I got the "official" gentoo XFS 2.4.18 sources (how did I miss the preempt option in there?). So, I was actually adding my 2 cents on the "it's not XFSes fault, they just don't stick together" kind of thing.

I am sorry I only saw your answer now... but don't you get a feeling the forums are a bit chaotic? Perhaps we need a threaded replies tree so we can check faster when someone responds specifically to us instead of the entire thread. Or at least, an additional "quoted by" search pattern. :wink:

I looked at my question and have no idea what I was thinking at the time :?

I really don't like these unthreaded discussion boards, but finding a good threaded one is so difficult I ended up rolling my own with PHP/mySQL. Damn nice it is too, but it isn't complete enough to offer as an option here. :(
