Which filesystem for AMD64

secondshadow · Guru Joined: 23 Jun 2003 Posts: 362

I should be getting my Athlon64 from FedEx today and I was wondering what filesystem I should use. Someone told me reiser is quite buggy on the amd64 platform so I was wondering what alternative would be next best? XFS?

You could try reiserfs... but if you're looking for stability you should go with ext2... if you want stability with journaling, you want ext3... of course, if you're wanting to mess around with things... go for reiserfs... or, you could install the system on ext3 and setup some storage that uses reiserfs and see how that behaves.

Hope that helps!

Well, i've got reiserfs for a month now without any glitches, my boot is on reiserfs too.

Im liking xfs, no problems since installing. I always used ext2 for /boot and am using xfs for / everything else gets nfs mounted.

I usually use reiser for / and ext2 for /boot...I just heard somewhere that reiser didn't behave in amd64. Methinks what I'll do is just use Reiser and see how it goes.

Good luck with your reiserfs partitions, its only a matter of time before they bork, amd64 or not.

You can probably tell, I've had to many bad experiences to try it again.

v4 is as buggy as hell, imo.

I've been using reiserfs v3 on my opteron for a little more than 2 months now without any problems. Just make sure you don't mix ext3 and reiserfs partitions, if you don't want to hit the bug mentioned in the amd-64 tech notes mentioned above.
BTW, has anybody tried copying files reiserfs->ext3 with newer kernels (2.6.3 etc), to see if it might have been fixed?

huh....thats interesting. I'm using reiser right now. I have /boot formatted with ext2. Don't really see the point in journaling a 100MB partition that I almost never mount. And if need be I can format it using reiser or re-format / with ext3 after backing everything up. Knoppix is a wonderfull thing sometimes. I will say though that I already installed a kernel and no kernel panic. But I will keep it in mind. Maybe I'll switch it when I get home just to be safe...

FWIW, I've got my /boot on ext3 and am running reiserfs on everything else. No problems copying kernels (yet). I haven't tried copying from ext3 to reiserfs. *shrug* Maybe I'm just lucky; I assume that warning is there for a reason. I'm on an Athlon 64 3000 / ASUS K8V Deluxe / Plain 'ol Seagate 60gb hdd.

Well...I've got reiser for / and ext2 for /boot...it all works fine...So I think I'll leave it. I make regular backups of /usr/portage and I build packges for EVERYTHING so I think I'll be okay. Now I think I'm off to fix my 32-bit gentoo (will be used for gaming and possibly a few benchmarks just to test what I've heard about better performance from compressors).

Didn't experince the bug here reiserfs/ext2 bug here. Maybe it was fixed in 2.6.3

been using ext3 for as long as i have had a amd64 and it works great no issues at all.

I read in the Athlon64 gentoo technotes that XFS supposedly works okay. I used to have a link to performance charts between the the different FS's and I can't remember how it performs vs ext3. I remember a while back not being real happy with ext3's performance...I think, if I remember correctly, its CPU utilization wasn't all that great either (a bit on the high side).

EDIT: PS@TuDemonic, actually I'm glad you mentioned this. I'll have to keep an eye on it...and my backups regular.

I'm really interested in other users experiance with Reiser (3.6, not 4. 4 is still tooooo beta for even me :twisted:

)

use only ext3 journalized or XFS (for /home or for /var)
it is highly stable and usable.. dont use XFS for /boot or /

reiser is stupid and slow thing..
all other fs same

No word on reiserfs updates on 2.6.3, I extensivly tested on 2.6.2 and reiserfs was borking in combination with ext3. But also noticed corruptions on reiserfs only....

ext3 all fine

hehe...

reiserfs is not acceptable choice under highl load env..
and, also, reiser is very specific fs. many small files warehousing ...

and... in production mode peoples can use anything

) for example reiserfs partition for storing large oracle database files ;-)

)) I see them...

haha

amax, have you ever cataloged the files on a typical system? What's the average file size, would you say? If I had to venture a GUESS I would say that the average file is well under 1Meg...so if ReiserFS stood up well for these "small" files then I would have to say that it is probably the best one for the job. ALSO, if memory serves Reiser outperforms ext3 in just about everything with the exception of the unlink operation. Since unlinks are far less common than searches or reads, for example, I again would have to say that ReiserFS is the best candidate for the job. Also, a number of high-performance database systems that I have been told about understand how to use a physical drive or partition rather than a file on a filesystem this not requiring the overhead of a filesystem to begin with.

In short, if you don't have anything really and terribly usefull to say I respectfully request that you not say anything at all. I would personally post numbers but www.namesys.com appeared to be down at the moment so I can't. I will say, however, that ext3 is by no stretch of the imagination faster than reiser so please don't make such claims unless you are willing to provide verifiable and reproduceable proof in the form of a GENERAL CASE senario, not some outlandish "well this FS only has 7 10 gig files on it so <insert fs> performs better." The fact of the matter is that most, though not all, are more interested in normal use performance when questions like this are asked. In closing, refer to the first sentence of this paragraph.

i have dualboot gentoo32/gentoo64,
for both roots i use ext3, for /usr/portage and /var/tmp/ i use reiserfs
for /home i use xfs.
noi problems so far

Well, I'm happy to report that I've yet to have any issues with reiserfs. Actually I've had better luck with it in 64-bit than in 32. It's survived quite a few hardlocks with X relating to attempting to use Radeon drivers (I know, it said not to...but I had to try) with the only thing being required to fix the FS was the replaying of a couple of transactions. And I use ext2 for /boot and I've not had any issues. I don't quite get the point of journaling a 100MB filesystem that never gets mounted "rw" anyway, personally.
