I really didn't like ext3 because it's soooooooooooo sloooooooooooow. But right now I'm using ReiserFS and it's really fast. But I think I might have some data problems. ( I know using ReiserFS was a risk but it's worth it :D ) So my question is what other journaling filesystem can I use for PPC that's as fast as Reiser?

You could try JFS which is - at least performance-wise on IA32 - the fastest filesystem in many respects. I don't know about its performance on PPC32 tho. And it might not be as stable as ext3. Remember, ext2 is the tried and true filesystem on any Linux installation.

I am using ext3 for PPC32 and I have also used xfs. I found neither of them to be "slow" - but that really depends on the things you plan to do with your installation.
I am now using ext3 for PPC64 and it is also ok tho I would take xfs if it was available (still experimenting with kernel compilation on PPC64).

i think that depends on what you wanna do on the file system? is it for very big files, lots of small files..? for static data, or data which is wiped and overwritten all the time? there are so many factors, that there just isn't a best-for-all filesystem.

actually couple of days ago, i read some benchmarks with ext2, ext3, ReiserFS, JFS and XFS on the net. can't remember where however, but you might find something wth google. the benchmarks stressed all kinds of things like working with real big files, or creating a huge number of tiny files in a directory,... there you could see that each filesystem has its strong sides. but overall, ReiserFS seemed to perform best (in the sense that it was the fastest to complete the whole benchmark set).

personally, i use ReiserFS3 for everything except my home-directory... my home-dir is ext3. guess i just have more 'confidence' in ext3, but ReiserFS is definitely faster. but i haven't had any (stability) problems with ReiserFS yet. allthough my iBook has crashed several times (nothing to do with linux, but with a hardware problem), it has always recovered without any problems. but then... i might just have been lucky.

EDIT: the the benchmarks i read

I'm using reiserfs on my iBook for quit a long time now. Never had any problems...
But on x86 I had a lot of problems and data loses with reiserfs. So, if I had to decide now what filesystem I should use on my ppc it would probably be xfs and not reiserfs.

I'm testing XFS on /usr/portage partition, and it seems to works well.
First I was trying reiserfs, but when moving the portage in the partition it get a nice segfault(after about 200MB)! Then was impossible to shutdown the machine...

XFS might be my next filesystem if I can't rebuild my ReiserFS system.



Thanks for the replies. :)

Ok so the problem is that whenever my computer freezes due to Kismet and my wifi scanning (I'll fix that later) it seems like I've lost some data. X.org starts to lose transparence with KDE and then random restarts of X. And well you get the point. That's with Reiser on a Dual USB G3 iBook. I really just want a stable, fast journaling filesystem. I've tried Ext3 and it was slow. I'm about to reinstall Gentoo again on my iBook after I zero all the data on the drive again :( But I've heard good and bad things about XFS and JFS. I really don't work with really big files. I use my box for Wardriving, school, Mp3's, DVD, games and other simple things. later on I hope to use it for programming and some network encryption. Unless I'm doing something wrong with the installation of Reiser when I install Gentoo. I don't have any clue on why Reiser won't work.

Did you try reiserfsck? And when does your system lock up while scanning - it has never happened to me before...

Well if you do some havy-duty wardriving, when collecting data to break a WEP key you will have some *really* big files, let me tell you :wink: And if you also want to rip DVDs and not only watch them you will be officially dealing with large files.

Reiser3.6 has been working really nicely for me so far. I have even started toying around with Reiser4 patches, but I think even though it's working I'll wait until it's officially in the kernel tree.

I guess the best solution would be to use a combination of file systems, e.g. have your /usr on a reiserfs your /home with all mp3s, games and movies on an xfs and so on. Combine the strengths of all the filesystems for an optimal performance.

I've tried Reiserfsck and still nothing. I never made seperate partitions for /usr /home and etc how much space should I make for those partitions?


I only have a 20GB drive. And I want to keep OS X on it just to mess around with it. So I'm thinking of giving OS X like 7-9 GB and the rest for Linux.
