I'm guessing the one in 8.0 is an older version because i found it performs abysmally. It seemed stable enough but i used it for backups with lots of file creation and deletion and my jobs took about 10 times longer to run than on ext2 or JFS (also included in the 2.4.18+ SuSE 8.0) For other use it is probably fine. I look forward to trying newer versions. While i'm talking about it online resize including shrinkage is a fairly high priority for me. Any journaling filesystem without that feature is going to be a second-rater. So without it XFS is unlikely to become a primary filesystme choice for me. That said, i'm glad to see variety in the journaling filesystems and look forward to XFS getting in mainline so we can use whatever filesystem that best meets our needs. This of course means that we will need decent, independent, comparisons of the filesystems. And think about this: In almost all other OSs of substance you have one or two basic filesystem types and if you want journaling you have to pay extra for it. And journaling filesystems don't have to be fast, there is very little real competition. -- ________________________________________________________________ J.W.

Personally, I've switched to Reiserfs (thanks, Hans!), which I'm _really_ happy with. Yeah, I should investigate the other options, but, honestly, there isn't a lot of neccessity to. > And think about this: In almost all other OSs of substance > you have one or two basic filesystem types and if you want > journaling you have to pay extra for it.

FWIW, I think this is a wonderful feature, albeit potentially confusing to a Newbie For my O2 running IRIX I get XFS whether I like it or not, for Solaris I get UFS no matter how much it sucks (I'm not really saying that it does; I don't have much knowledge of it to be honest). This multitude of choices really causes competition between them, and makes them all better in the long run. Think about this: Namesys is working on Reiserfs v4.0. v4.0. Hell - it's only been incorporated into the mainstream kernel for less than a year (at least by my recollection), yet it keeps advancing. I have _no_ idea what UFS version Solaris 8 is using (admittedly at least somewhat due to ignorance -- I use Solaris because I have a good ol' SPARCprinter which alas is not supported by Linux), or whether they've bother to do development on it to make it better, faster, etc. Yet, _we_ get this advancement all the time. Isn't it great?! Ok, time to step off my soapbox and get back to work. -Nick ^ permalink raw reply [flat|nested] 42+ messages in thread

No, that's probably a good thing. I don't care how good any programming team might be, an implementation written from scratch probably should burn in for a while before going in anywhere it might be used for production. And with all respect to the group, a 4th rewite from scratch in only a few years suggests that the ratio of coding to designing is pretty high. -- bill davidsen <davidsen@tmr.com> CTO, TMR Associates, Inc Doing interesting things with little computers since 1979. ^ permalink raw reply [flat|nested] 42+ messages in thread

If you want to object to XFS, object that it hasn't been rewritten in recent times. As for the notion that the more designing you do, the less rewriting you need to do, it is a bit like the belief that the better your scientific theories the less you need to perform experiments. Projects that are no longer attempting rewrites of their cores are dead in their soul, and their authors should pass them on to someone younger. That said, version 4 will be followed by semantic enhancements and distributed filesystem work, as I finally have in version 4 a storage layer good enough that I can move mostly to the tasks that first interested me about FS design. Most of the stuff that needs improvement in the version 4 storage layer can be done as new plugins, or so I fondly hope.;-) Hans ^ permalink raw reply [flat|nested] 42+ messages in thread

Exactly so. I spent several decades doing software development at GE's Corporate R&D Center, and I had ample proof that both of those things are true. I think the phrase you want in English is "fewer experiments you need to perform," but you did see the principle. > Projects that are no longer attempting rewrites of their cores are dead > in their soul, and their authors should pass them on to someone younger. Hear that, Linus? Off to the retirement home with you unless you "rm *" your source tree and "go back to Baltimore and start over again as a virgin." Actually I think that Linux is an example of major software designed from the start to be rewritten in parts and to evolve as a whole. no clean sheet of paper needed. -- bill davidsen <davidsen@tmr.com> CTO, TMR Associates, Inc Doing interesting things with little computers since 1979. ^ permalink raw reply [flat|nested] 42+ messages in thread

On Solaris and some other platforms you can, with lots of money, buy a license to run the Veritas journaling filesystem. It comes with a license manager and you have to get license keys to mount the filesystems. Ever had a filesystem not come up after a reboot because the license expired, i have (ouch, i told management to renew the license). Is veritas fast? I don't know. They hype the journaling, not speed. And what are you going to benchmark against?. Recently Veritas announced they were going to support Linux. I'm curious to see how they fare in a shootout with the other journaling filesystems.

Fantastic. And that is largly without competition. Just wait and watch what the JFS and XFS developers do to improve their products to keep up. As for UFS, the only thing they can do to it is to adjust the block allocation heuristics.

They have extent-based allocation, which is good for their greatest hype - performance with databases (see all the marketing shredder-food about [Cached] QuickIO). They have hot resizing, which fast as hell (again, compared to UFS), they have snapshots, which are cool. And don't forget the GFS capability, which I am yet to see in action.

They have extent-based allocation, Comparing Veritas FS against UFS is like comparing apples and steak. Their goals are so diffent it is rediculous.

More to the point, a quick scan of LKML will show that there are fixes for ext3 and reisser on a regular basis, so one must assume that they don't always work as they should either.

At this stage I would hope he will at least tell you why it wasn't accepted, since XFS is a desirable feature for many people (as evidence vendors providing it). I'd like XFS, I think it's a good feature politically, hopefully it will not just drop just as it's becoming stable for non-critical production use. -- bill davidsen <davidsen@tmr.com> CTO, TMR Associates, Inc Doing interesting things with little computers since 1979. ^ permalink raw reply [flat|nested] 42+ messages in thread

The problem has always been that XFS was very invasive code so it might break stuff for people who dont choose to use experimental xfs stuff.

Thats slowly improving Alan - The last patch Christoph posted against 2.5 is not the least bit invasive. Excluding documentation and configuration files, these are the changes: o 1 new process flag: +#define PF_FSTRANS 0x00100000 o 1 new CTL_VM name: + VM_PAGEBUF=18 o 1 new CTL_FS name: + FS_XFS=17 o 1 exported symbol: +EXPORT_SYMBOL(mark_page_accessed); and of course an addition to fs/Makefile: +obj-$(CONFIG_XFS_FS) += xfs/ That's it. The rest is under fs/xfs. (2.4 is more invasive, but this thread started out talking about XFS in 2.5). -Eric -- Eric Sandeen XFS for Linux http://oss.sgi.com/projects/xfs sandeen@sgi.com SGI, Inc. 651-683-3102 ^ permalink raw reply [flat|nested] 42+ messages in thread
