Being that I just switched to reiserfs which came with FC2, I was wondering if Fedora Core 3 will be released with ReiserFS 4? If anyone has any info on this that would be great...

Im looking forward to FC3 like its Christmas.... :)

I hope FC3 will come with Reiser4.

If not... I will manually install Reiser4 then :)

Wow. the stats for reiser4 are impressive..

I wonder if windows or someone think of a way to mount reiser4 drives in windows :D... if not.. it's still all good :)

you can run (on Windows) something like coLinux with some minimal distro on top of it, than you can mount any FS that Linux supports and export it via Samba for Windows host...

i think you just answer and issue i am having with mounting mkd 10 from the grub....i believe during installation that is the type of partitions mkd is using....

you can always use another FS for /boot partition...

Han's tells you not to run rs4 on /boot, you should use ext2/3

I've ran rs4 on a gentoo box on / and /home and when i get a chance I will mv / on a test fc2 box and format it with rs4 and bring it back and see if she lives. (of course you have to roll a kernel with the patch - mm-sources)

I certainly hope so. I also hope Gnome 2.8 and Xorg 6.8 make it in.

here's a thread on the fedora-devel mailinglist about Reiser 4. There are some excelent points made: http://www.redhat.com/archives/fedora-devel-list/2004-August/msg00954.html

here is the schedule (http://fedora.redhat.com/participate/schedule/). is reiser4 really stable yet, sure they released it as stable, but so did redhat with fc2 and there were a few known bugs. with a filesystem, you can't have bugs becuase the result will be lost data and thats not acceptable for any computer, no matter how cuting edge.

I'm still running a box w/ reiser4 (gentoo) and it is been stable for me. I've gone through the reset test/pull plug and the system has come up just fine.

If I have time this weekend, I still plan and giving rs4 some time on my dual xeon box, I haven't booted in the fc2 for over a month and been using my rawhide install so I figure I'll format fc2 to reiserf4 and mv/cp the data from my rawhide slice and adjust grub accordingly and see what happens. (just have to find some time) ;(

edit:

Just found some reiser4progs rpms from:

http://apt.bea.ki.se/kernel-desktop/fedora/linux/2/i386/kernel-desktop/SRPMS/

So atleast I wont have to build those ;-)

did you unplug thw box while the system was under heavy load? that will really test its ability to recover, and that usualy the only time disaster strikes ;)

I wouldn't say it was under heavy load, just going about doing stuff and unplugged.

Why don't I just clear this up: NO! Fedora Core 3 will not include Reiser4.

I have a great personal interest in Reiser4, I provided testing during the release phase via the love-sources kernel tree and Reiser4 is fine for day to day use, I have a machine running it right now. But it's not in vanilla and the stated goal is to keep as close to vanilla as possible.

Also there are some issues, like Reiser4 still doesn't compile with 4kb stacks, it's only been tested on i386 and there are semantic issues that amongst others Al Viro and Linus have been critical about. Meaning we probably won't see Reiser4 in mainline anytime soon and definately not in FC3.

Regardless Reiser4 has some interesting features, and I'm looking forward to seeing where this goes in the future.

Just curious, what FS does FC use at the moment? I'm guessing it's Reiser3 yes?

superbnerd

no, the default linux filesystem is ext3 :(

There is no default filesystem for Linux. there are default settings for DISTROS, but linux itself has agnostic. Most distros tend to favor ext3 or ReiserFS3 - RedHat has historically backed ext2 and now ext3, so Fedora does use that as it's default but you can by passing arguments to the installer get support for JFS, XFS and ReiserFS.

some one left this comment in my reputation section:

and i qoute ..."Unsubstanciated guesswork not taking into account of RedHat history of spreading FUD about Namesys products - either way Reiser4 is FAR from ready to become the default FS for Linux, and it quite possibly never will be for so many technical reasons."

and please dont get me wrong but how can you explain this other article, because i understood it will not be possible to use ever, now here is article and benchmarks:
http://www.namesys.com/v4/v4.html

please let us know why is not possible to use for so many technical reasons?

The reason I say ReiserFS 4 won't make it into Fedora Core 3 is that including it would be a big change. Big changers don't happen so late in the development process.

In addition to this, the Red Hat developers have a slightly negative attitude to reiserFS, as there's been some difficulty getting the upstream ReiserFS developers to handle Red Hats issues. After reading the core developers response to this question on the mailing lists, I'm almost certain ReiserFS 4 won't make it into Core 3. If it gets more stable and the developers get more cozy, it might make it into Core 4, even though I think ext3 will be the defauls filesystem for quite some time.

Either way there has been a great deal of debating on lkml about Reiser4 and Hans Reiser personally since he's trying to make Reiser4 more intrusive, violating POSIX standards in the name of progress.

Regardless Namesys has gotten themselves a bad name since they were the first to make a journalised filesystem to be included in the Linux kernel, and back then it was buggy and had no fsck program - you can just imagine what amount of fun that was, I was an early tester and I did feel the pain of many a bug in ReiserFS3, so I can understand why some people, especially those who's business depend on it are a bit... addiment to hail Reiser4 as the solution to all our problems.

I have a Reiser4 system running, and there are very few issues with it in daily use, but I'm not sure I would run out and install it on production servers till it has seen more testing.

But word is that Fedora will support Reiser4 the same way it supports ReiserFS , JFS and XFS but not for FC3, maybe FC4 depending on Reiser4 making it to mainline.

in other words.....like i previously stated, maybe be the standare in the future. i never said or mention it will be included in fc3, just stated the possibility of the future.

I noticed imdeemvp was banned, was that because he posted something from a PM, but left it annonymous?

What do you have to do to get banned?

And, what a lot of folks don't realize is that services and applications like PostgreSQL also come back up without data loss. Here in Tornado Alley storms come suddenly and when lightening pops outside I don't hesitate to protect my box by yanking the power cord out of the wall without doing a shutdown. Sometimes the first strike takes my section of the powergrid down, and my box with it. When power comes back up I'm back in business without a loss.

I've been using ReiserFS since SUSE 6.4 without a single incident of data loss during who knows how many accidental or forced shutdowns. I installed reiserFS during an FC2 install by using "linux reiserfs" at the install boot prompt, and FC2 running ReiserFS exhibits that same behavior as it did on my other installs. Very comforting. I've even disconnected my 500W UPS a couple of years ago, after an identical UPS at work, which always tested OK when I pushed the test button, died with the PC during a power outtage.

It's also nice to know that my wife has an easily understood instruction on how to do an emergency shutdown on my home box! :)

For the first time ever, I've been using XFS on a four disk RAID0 and it's performance has been outstanding so far. If I'm hearing you all correctly, I could expect even better performance and better reliability from ReiserFS4 ???

That I would have to see and try. ;)

For those interested in ReiserFS4, take a look at this LWN.net link (http://lwn.net/Articles/100148/). IMHO, Hans has his work cut out for him convincing the Linux developers that the major changes he proposes are the best/right way to go.
