Let me offer some suggestions: 1) XFS has just been released - no significant testing has been done. Before anyone can entertain the suggestion that XFS is the best journaling system around they should have a large volume of test data to support such suggestions. 2) ReiserFS has been on SuSE since 6.4 and, for example, is being used in production where I work. It's been up since Sept 17,2000 without a crash or data loss. And, my Microsurf co-workers insist on rebooting it every week in order to use Norton's Ghost to mirror the HD. That's 28 reboots without a failure. (I wish they'd have used a Linux backup utility like tar, but they carry with them a distrust of software stability earned through long experience with WinXX. While milage may vary depending on the hardware envolved, and the configuration of Linux and its supporting applications, anecdotal evidence like mine is better than the blue-sky theory which is all the XFS has for support.

Jonathan;

Why would you think it _should_ be better? New version # or something? I just don't get that at all, maybe it is worse, ever consider that?

1) XFS has just been released - no significant testing has been done. Before anyone can entertain the suggestion that XFS is the best journaling system around they should have a large volume of test data to support such suggestions.

XFS has been used in enterprise level environments (on IRIX) since 1994. I'd call that pretty significant - certainly more than ReiserFS has been subjected to. The gap in the XFS solution is the link between the fs and the linux kernel, and that's what SGI have been working on for the last year or two. I'm sure they have it pretty stable for v1.0. Of course, ReiserFS has only been at 'v1.0' since the advent of the 2.4.1 kernel, so the same applies there I suppose. As far as I know there isn't a large volume of test data for either system on Linux, at least not public. But if SGI work like we do (I'm at IBM's Storage Systems Group) they'll have put it through more formal testing than Reiser will ever be able to do. I suspect most people on this list are used to desktop PCs. One look at our test lab would make the jaws of most people from that background drop. I wonder if ReiserFS has ever been worked flat out by a 24 CPU machine like the one not 3 metres from where I'm sitting right now? I know JFS has on AIX ('cos I ran the test!), and the Linux version will too, before it ships as v1.0. I suspect SGI have similar procedures. That's the benefit of having a multi-million dollar company behind you. I don't know how Reiser test their product so I'm not going to knock them, but your claim that there has been been "no significant testing" of XFS on Linux is almost certainly way off.

2) ReiserFS has been on SuSE since 6.4 and, for example, is being used in production where I work. It's been up since Sept 17,2000 without a crash or data loss. And, my Microsurf co-workers insist on rebooting it every week in order to use Norton's Ghost to mirror the HD. That's 28 reboots without a failure.

Does ReiserFS serve NFS files yet? I can't - not won't, but can't - use it until it does. And I mean reliably, not some hack.

While milage may vary depending on the hardware envolved, and the configuration of Linux and its supporting applications, anecdotal evidence like mine is better than the blue-sky theory which is all the XFS has for support.

See point one. XFS and IBM's JFS have been around for years. From the ramblings of Hans Reiser which I've read I know who I suspect as having "blue-sky theory". (Go to http://www.namesys.com and click on the "Future Vision" link. The guy clearly has a brain the size of a planet, but I've never been quite sure his feet are on this one!) Disclaimer: I speak for myself and not IBM. None of the above should be taken as indication of IBM policy or practice.

I am not defending anyone or anything..I am not getting in the middle of a filesystem holy war..but what Jon and others have said was/is that "SuSE" hasn't tested it completely..meaning with the "SuSE Distribution". As others have said, it appears to have a lot of RHcentric ..ummm.. issues such as liking GCC 2.96.1. Going off on rants about what's tested..not tested and who tested .. it is pointless. Until the SuSE guys are confident that it works with what they put together..it most likely won't be include yet. Everyone just calm down...sheesh.. }=}Reiser test their product so I'm not going to knock them, but your claim that }=}there has been been "no significant testing" of XFS on Linux is almost }=}certainly way off. -- Ben Rosenberg mailto:ben@whack.org ----- If two men agree on everything, you can be sure that only one of them is doing the thinking.

I believe they have alot invested in reiser and don't want to appear as if they aren't in full support of reiser

This, to a degree, is true.

so you may NEVER see it on a SUSE dist.

But this is, pardon the language, utterly wrong! Of course we will eventually include *all* the journaling file systems (ext3, XFS, JFS) if they prove to be solid in their Linux implementation and coexist with the other journaling file systems. I know XFS has had some issues but I do not know the current status. So I'll just wait and see what happens. BTW, that XFS has a proven track record on other OS doesn't mean much to me, as that still leaves quite a bit to do wrong in the port to a new platform. Let's just wait a bit and see what experience people have with it. -- Penguins to save the dinosaurs -- Handelsblatt on Linux for S/390

Hi Woops mistake no 1 watch that subject line when sending a message (I appologies Sorry). I am rather new to this list and I have one of the most basic questions that seem to go beyond the installation support offered by SuSE.... Please could someone post me a very simple setup for configuring a gateway to connect 3 linux boxes to the internet where the modem is only connected to one box... ie internet <--->modem<--> box1 <---> box2 <--> box3 So that all the users can connect to the internet. my network is setup with box1 192.168.10.1 box2 192.168.10.2 box3 192.168.10.3 hostname box1 = linuxbox1 hostname box2 = linuxbox2 hostname box3 = linuxbox3 All I need is edit this file .... type this into it etc.. etc... Any ideas ? Regards Matt

Hi

I am rather new to this list and I have one of the most basic questions that seem to go beyond the installation support offered by SuSE....

Please could someone post me a very simple setup for configuring a gateway to connect 3 linux boxes to the internet where the modem is only connected to one box...

ie internet <--->modem<--> box1 <---> box2 <--> box3

So that all the users can connect to the internet.

my network is setup with

box1 192.168.10.1 box2 192.168.10.2 box3 192.168.10.3

hostname box1 = linuxbox1 hostname box2 = linuxbox2 hostname box3 = linuxbox3

Assuming you can get on the 'net from box1 all you have to do is on box2,box3 set the gateway to box1 Kind regards, -- Gerhard den Hollander Phone +31-10.280.1515 Technical Support Jason Geosystems BV Fax +31-10.280.1511 (When calling please note: we are in GMT+1) gdenhollander@jasongeo.com POBox 1573 visit us at http://www.jasongeo.com 3000 BN Rotterdam JASON.......#1 in Reservoir Characterization The Netherlands This e-mail and any attachment is/are intended solely for the named addressee(s) and may contain information that is confidential and privileged.

Dont forget to set up masquerading if you need it. There is a nice HOWTO which explains that very well. If you are using a 2.2.x kernel you have to read it.

Well -- no bugs, crashes etc. Runs like a charm. It is on my laptop, so wrt performance I cannot say anything. And logrecovery is really fast. Seems to me as a good fs, and I'll not be surprised if it makes it into the kernel pretty soon.

There's still some issues with it though; it is a port of the Irix XFS, so it is not really finished yet. Haven't looked into 1.0 yet though.

I have a question wrt XFS... does it have the extended attributes, as ext2 does? So you can set the t bit, etc? ReiserFS doesn't, and it bothers me. If XFS does, then that is a step in the right direction. Thanks for any info, Steven
