Ext4 by default

[int]

Please add ext4fs and choose for installation...
Reasons:
1. Speedup file removing
2. Better and faster allocator
3. Bigger max file size
4. Precision timestamps
5. Bigger max number of folder inclusion
6. Faster indexation
7. Faster checking
8. Re-allocation for better video recording, torrent downloading etc.

I'd definitely want to take ext4 for a spin, but as default it would really be bad if there's problems. Better let it be optional so people have to choose to take that risk.

It normally takes years of usage to be sure there's no surprises, right?

http://fedoraproject.org/wiki/Features/Ext4

Indeed, I have been running on Ext4 since early in the F9 development cycle. I have never seen a problem with using it on my machines, and now that it has left behind the development status upstream it signifies a good time to adopt.

If Fedora 10 had not been in a development and feature freeze, the maintainer of the feature has expressed a desire to have pushed for the switch to be flipped and default to ext4. I suspect this will happen first thing after F11 development opens. As such it would probably be a good time for Ubuntu to adopt as well, share the experiences yet not the pain (since ext4 is an evolution of the stable ext3 code and has been tested heavily in Fedora for a year every major bug should have been shaken out of it making it low risk).

I would strongly favor adopting ext4, it has been very good to me and many other people. Also I have not heard any horror stories of ext4 eating babies from any of the testers which is also a very encouraging sign.

[Timon&Pumba]

There should also be ext4 support in Grub, so that we can boot from an ext4 filesystem.
But I get it is not too hard to develop that in 6 months, or is it?

I believe openSUSE had a Google Summer of Code student who worked on this, I don't know how far along that project has come though. But if we can't make this work before Jaunty, the simple solution would be to create /boot on a small separate ext3 partition (which is also a good idea since that allows us to mount it only on demand, lowering the risk of accidently kernel image corruption).

http://code.google.com/soc/2008/suse/appinfo.html?csaid=91DC4C762E7EE6D7

Grub2 apparently supports EXt4 with extends, so that is one solution right there though not without issues.

[apoth]

By default would be preferable, but not if there's more than the absolute tiniest risk of data loss.

[Quikee]

Now that it has been out of development it should be available at least as an option. There is no need to rush and enable it by default just yet - anyone that wants it can migrate from ext3 easily.

Well...

Ext4 is hardened with kernel 2.6.28 and with RC2 some bugs are fixed

http://lkml.org/lkml/2008/10/26/159

This one is also important:

http://ext4.wiki.kernel.org/index.php/Ext4_Howto

For people who are running Ubuntu

For people who are running Ubuntu, it is *highly* recommended that you download a set of modified util-linux packages and install them. Packages for Ubuntu Hardy are available here. These packages revert a change made by Ubuntu to use the volid library instead of the blkid library. The volid library has a number of shortcomings, including that they don't work on freshly created filesystems or swap devices until after you reboot (since it is tied to udev probing) and the volid library doesn't understand ext4dev filesystems. The blkid library is much better, and Debian uses the blkid library for util-linux. Unfortunately, Ubuntu chose to make this reason for some unknown reason. For other versions of Ubuntu, the patch that was applied can be found here.


So this must be clarified and also that testing starts as soon as possible.

We cannot let others do the "hard work". !!!

I don't believe its possible with default EXT4, but maybe...:confused:

(This also means that users which understands backups can test....)

[PatrickVogeli]

I'd rather choose xfs or jfs, both of which seem to perform better than ext2/3 and have been longer around than ext4

[gnomeuser]

Now that it has been out of development it should be available at least as an option. There is no need to rush and enable it by default just yet - anyone that wants it can migrate from ext3 easily.

Actually the migration is not as easy as it would seem. Merely changing ext3 to ext4 in fstab is not enough to gain the full ext4 feature set. You would currently need to reformat (or do a fresh install) to gain the optimal settings. A converter is not yet available (but should amply be possible to create).

One could do such a migration in a second stage upgrade such as Fedora's Anaconda/preupgrade, mainly this would be a good idea because messing with the partition resizing and moving all the data on a running system would be.. unsafe at best.

[Changturkey]

Maybe for 9.10 or whenever Grub2 is out?

[gnomeuser]

Maybe for 9.10 or whenever Grub2 is out?

AS Matthew Garrett puts it, grub2 is going to be the ultimate bootloader for GNU Hurd. It has been in development so long it's unfunny. It's still not complete and likely won't fit every scenario we need for a while. Worse still upstream have all but abandoned grub1 which everyone uses so we pretty much using unmaintained code which won't support ext4 unless someone produces the patch and maintains it themselves.

3 paths logically then present themselves:

1) Add support for ext4 (and btrfs which will also be needed soon) to grub1
2) Put a massive amount of work into helping finish grub2
3) Find an alternative to grub such as extlinux

Of these number 1 seems the most likely to be the outcome short term.

[Eclipse.]

There is no chance of it being default.

Ext4 still isnt bug free and we need to wait for grub2 (or patch grub1, the first option seems more likely).

Possibley see it available but definetly not defauult.

[bash]

Sure like to see ext4. But as I said in another thread, not if that ends up in a Pulse Audio like mess. There also Fedora picked it up first, everyone was enthralled because it sounded brilliant in theory, but what then ended up in Ubuntu should have definitly not been put in a LTS release. So all I'm saying is: If it's ready, great, then take it and put it in. If it's not though, then please don't rush it in, just so we have it (Offering it as an option then would be ok though).

[insane_alien]

ext4 should be an option in the next release, jaunty+1 can have it by default as it should be stable enough to take up the mantle of ext3 by then.

[plun]

Well... instead of discuss, how do I setup a ext4 partition ?


http://ext4.wiki.kernel.org/index.php/Ext4_Howto


I have 3 partitions and can easily test with one....:)

I was not aware of this. As far as I read all needed to do is to enable at least on of the feature of ext4 (extends for example) via tune2fs and the migration will be performed automatically in the next mandatory fsck run.

[Slug71]

I'm all for EXT4 as default for all the reasons the OP said. I think the only way EXT4 will have all the bugs ironed out is for more people to be using it and therefore should be included from Alpha 1.

If it can speed up Ubuntu then thats definitely a plus too.

If it can speed up Ubuntu then thats definitely a plus too.

ext4 is already very bugfree, it builds on the ext3 code which has been vetted for years. It has also been tested by hundreds of volunteers over the past year in Fedora alone (just check the smolts.org stats for ext4dev and ext4 - the latter is low for a good reason, the name only just changed and smolt only updates once a month so it will take a while for even all F10 testers to get onboard).

Aside that a few of the developers have moved production machines to ext4 and while it still doesn't have all the planned features the disk format is forward compatible. The only changes might be tweaks at mkfs time for optimal behaviour but it's not in flux at all. It's stable code.

As for speedups, I will be honest, I don't feel any with my current setup. fsck is faster which is nice but it's an evolution not a revolution (like btrfs is). It brings much needed features to the old and trusty ext3 code, it is faster in most benchmarks but as a user you are unlikely to experience it as a big upgrade. You should not press for ext4 for performance reasons, io is slow regardless of what filesystem you use, it will always be painful so it's better to look at the features we gain. Ext4 is significantly better at scaling to todays large disks, fsck is a big problem on ext3 something ext4 will bring much needed improvement to (multiple TB disks such as is found on kernel.org can take days to perform fsck, which is completely unacceptable downtime). As drives keep growing this problem is increasingly finding it's way to end user desktops, I am already seeing this on my machine and I only have slightly less than a terrabyte of storage in this machine (considering that 1.5 TB drives just started coming out with the promise of 2TB drives in Q109 - this will be a problem on every machine near you soon).

[gnomeuser]

Ext4 still isnt bug free and we need to wait for grub2 (or patch grub1, the first option seems more likely).

Okay then please point me to said bugs, also please explain to me how we find them without testing (never mind the fact that we actually have been intensely testing ext4 for over a year on production machines without hitting major bugs).

You also should mention that the support lacking in grub is not booting into ext4 but having /boot on ext4. A problem we can get around either by having a separate /boot which is a perfectly fine compromise till such a time as a patch or grub2 is ready.

[Slug71]

So i've decided i'm gonna be on board Jaunty with Alpha 1 since the final of Intrepid seems to have gone backwards for me.

If EXT4 isn't included with Alpha 1 of Jaunty, what will be the best way for me to mount it?


Why not include the Alpha or whatever stage Grub2 is at now with Alpha 1 so that EXT4 can be included? Perhaps this could help Grub2 move along a little faster with more people contributing??

[SunnyRabbiera]

I think ext4 should be made optional as many still use ext3 and we dont want people to break their systems.

I will say this now, no guarantees, a quick way that should work, but remember never.. ever.. under any circumstances change the partition you have /boot on to ext4, it will fail horribly. Double check before doing this that you have a separate partition for /boot.

If the module is compiled with your kernel (and I believe Ubuntu ships ext4 as a module). Then you can change ext3 into ext4 for existing partitions in /etc/fstab. This as I mentioned earlier will not get you all of the ext4 features but will allow you to fully rollback to ext3 in a purely harmless way.

You can also enable extends, the biggest new feature, to do this I would recommend working on your partitions while not live, so boot a LiveCD and invoke tune2fs -O extends /dev/sdXY (where XY denotes device and partition). Once you have done this, there is no going back to ext3, this needs to be understood fully, you cannot go back to your cozy ext3 ways when extends has been enabled on your partition so be sure you want this. Then I would run fsck on the partition just to be safe.

For this guide to work, your e2fsprogs package must be at least version 1.41 or higher. This version has ext4 support and will be needed.

This still will not get you to a full ext4 experience, since at mkfs time for a new ext4 partition certain parameters are invoked to attain optimal values. THese are set differently on ext3 partitions and cannot to my knowledge easily be changed. To get here thus you will need to backup your data and recreate the partition from scratch, also as these values are being tweaked currently a ext4 partition created now might not be fully optimal for all future changes but it will work, the disk format is stable and there is no obvious adverse stability effects to this.

I will however repeat, do not.. ever.. change the partition containing /boot to ext4, if you do not know how to determine which partition that is, disregard this guide entirely and wait for migration tools to become available or at such a time as installs onto ext4 are supported, do a fresh install.

[gnomeuser]

I think ext4 should be made optional as many still use ext3 and we dont want people to break their systems.

Existing ext3 partitions could either be left as such or upgraded to ext4 without extends which is 100% compatible and as such should you ever decide to go back to ext3 that is possible simply by changing ext4 to ext3 in fstab.

This method does not grant all the cool features of ext4 but it does provide a progression to ext4 without regressions and full reversibility.

Eventually an upgrade might offer a migration to a full ext4 partition, when well tested tools for this have been released or systems like this could be left in the non-optimal state forever to be extra careful.

[Metaleks]

Gonna have to vote no on this one. ext4 recently came out of a "hot development" phase, and while nothing thats really significant will be added to it, it needs a lot more testing. Even having it as an option is too much, in my opinion. I don't think there is a single doubt in anyone's mind that ext4 is better than ext3, or that it will eventually take ext3's place in Ubuntu. But until then, it really needs more testing. This is a file system we're talking about. Throwing even the smallest caution to the wind will be detrimental in the long run.

[plun]

Yes and this is a development forum where software should be tested... not endless discussions about rumours.

As soon as possible this testing must start !!

Maybe also Ubuntu can contribute to upstream... ???(real upstream).

Of course it probably will end in some broken file systems... thats testing and "**** happens".:)

I wouldn't have it as default in Jaunty but I think there should be a option in the partitioner.

A years worth of testing without any kinds of dataloss bugs or other regressions. It even managed to improve the ext3 codebase whenever a problem was caused.

There will always be bugs, it's a lot of code but it's not as you would have us believe a hotbed of change which is entirely untested as well as completely new. The filesystem has been deemed stable by it's developers. Cautious people as it already is.

You have a smooth incremental upgrade with the option of backing out fully to your existing ext3 partition for upgrades with NO RISK AT ALL as well as the option to jump full on to the ext4 path with all the new features enabled.

Hundreds of people use ext4 today and have done so for a year. No serious bugs have been found during the time of this testing, regression test suites are run on this code often and the tool suite is now complete. I don't understand what more safety you expect will come out of not testing it nor encouraging it's adoption.. for a development cycle (where we do changes far more likely to cause dataloss than the transition from ext3 to ext4 would on a quite regular basis).

This would seem to be a good time to include it and get testing - right at the beginning of a new version cycle.

It will for sure be there, the challenge is more to do important functions early in a development cycle.

Not wait for Debian, work directly with upstream. :)

We have several examples such as Firefox 3, OO-3, PulseAudio.

It will be broken PCs but thats better then a mess after release out of too short testing and lousy test procedures.

I agree, but who was discussing rumours? Is it really a rumour that ext4 needs more testing? I thought that it was fact. ext4 has been officially "stable" since October 11th. A mere few weeks have passed. All I'm saying is that lets not jump the gun and make it default for 9.04. I don't see the problem with waiting this out a little more.

I believe he was just generalising with the rumours part as they are always flying around the forum.

That is exactly why now is a good time to bring in Ext4. Ext4 will be the future for the next few years now and if its deemed stable then why not bring it in so that it can be thoroughly tested and polished?

[of_darkness]

if it is on by default then the boot issue must be solved 1st.

Grub2, well i loked arund the wiki for grub2 and nothing about X86-64 suport, only a test on a 64bit platform but no real plans on suport for 64bit so im very sckeptical about it.

Mabe fixing suport in leagcy grub so long as it dosent make it bad in any way and i think it is somthing that neads extensive testing ,more then 6months normal testing. if it got alot of testers doing some intensive try to brake it testing then maybe..


So put it optional untill its tested and working solidly as it is souch a critical pize of software thats neads to be treated whit silk glowes in part.

Grub2 must have 64bit support since they're both gonna be around for a while. But thats why i said Grub2 should also be added from Alpha 1 so that it can move along faster.

Ext4 has been tested for around a year now and has been deemed 'stable' as of Oct 11. Read Gnomeuser's posts about Ext4.

[kernelhaxor]

ext4 is alread out of development and testing is goin on .. I think it wud be pretty stable by next April .. personally, I would use it if available at least as an option

[BwackNinja]

Is there even all that much point in 64-bit support for grub2? Regardless if it is a 32-bit or 64-bit program, it should still be able to load operating systems, and having grub2 as the _one_ 32-bit app in a 64-bit install shouldn't make anyone cry. I have a 32-bit grub loading both 32-bit and 64-bit operating systems.

I can't wait until grub-legacy is out of the picture and grub2 becomes mainstream.

There should also be ext4 support in Grub, so that we can boot from an ext4 filesystem.
But I get it is not too hard to develop that in 6 months, or is it?It's something like this that makes me say it should certainly be an option, but not yet the default.

[MacUntu]

Make it an option. Ext4 left development state but still broad testing is needed to consider something as important as a filesystem stable enough to get default.

[gnomeuser]

Make it an option. Ext4 left development state but still broad testing is needed to consider something as important as a filesystem stable enough to get default.

How does +700 people running it for a year sound in terms of testing as well as artificial stress tests, without hitting major issues that is?

[MacUntu]

700+ doesn't sound overwhelming to me but I can't remember the beginnings of ext3 so that's just a gut feeling. On the other hand ext4 isn't something made from scratch...

9.04 dev cycle would be a good time to test ext4 "in the wild" but I'm not yet convinced it should be default.

It's also a matter of how far the software around ext4 is developed. Starts with GRUB, ends with all the tools eg. for accessing the partitions with other OS.

EXT4
Fedora 10 brings a fully ext4-compatible e2fsprogs. In addition Anaconda's partition screen has an ext4 filesystem option available if you launch the installer with the ext4 option.

Fedora 10 also brings delayed allocation for ext4. However, ext4 in Fedora 10 does not currently support filesystems larger than 16 terabytes.

e2fsprogs 1.41 is compatible, I believe that is what ships in Intrepid as well (or you have patches applied - I saw on the mailing list). also..go Fedora.. yay! (I had to)

[Sophont]

As an option - sure. Always nice to have options.

As default - I don't see how that makes sense. From what I gathered the changes on performances won't be felt by most typical users and the biggest advantages are for use cases that are not typical (very large files, huge filesystems, etc...).

So even when the risks are low enough there simply are no compelling features (for typical users) to make it worth *any* risk.

And that's without taking missing support from tools and grub into account.

Advanced users who really need it's new features and can make it work will also be able to install it.

Well, we are very early in development of a non-LTS release. I think ext4 would be a great idea considering the minimal risk. If anything does break, we can always switch anytime between alpha 2 and beta.

Also, it mentions improvements for torrents and deleting files. Both of those things should be considered highly useful for average users.

Let's not let fedora beat us

Yep exactly. EXT3 will always be there anyway for the people that do not want to use Ext4.

[poebae]

I'd be willing to be a guinea pig for an ext4 test. Given Ubuntu's massive userbase, this is a great chance for Ubuntu to contribute something back to the rest of the Linux community, by rigorously testing ext4 and reporting any bugs or holes.

I know that not every user shares my sentiment and they want their system to have the most stable, secure FS available, but it'd be great if ext4 was at least included as an option.

[Slug71]

Well according to Linus its ready to go.

http://www.linux-magazine.com/online/news/kernel_ext_4_filesystem_moves_beyond_developer_sta tus



Another reason to give us 2.6.28 ASAP!

[Progressive]

If Linus said it then that is The Word. I mean, who else needs to approve? Stephen Colbert?

[Slug71]

Yep,

And last i heard Ext4 is bootable with Grub Legacy. I either read it here somewhere or when i was searching Google for info.
Not sure how true it is but apparently it was just a bug. Hopefully it is true.

[Progressive]

If you look in the expanded list of Jaunty blueprints, you will notice that Ext4 is already added as a proposed feature.

https://blueprints.launchpad.net/ubuntu/jaunty/+specs?show=all

[RAOF]

It's worth noting that anyone can propose blueprints, and that blueprint doesn't seem to be associated with an active Ubuntu developer (as determined by MOTU, core-dev, or ubuntu-universe-contributors status). He could certainly go to UDS and suggest to have a session discussing the merits, though.

I don't have a firm grasp of the benefits/risks of EXT4, but I'm not sure that it's the best idea to go from "it's now declared stable" to "let's make it default". It'll already receive much wider testing by being available in Fedora 10 and (presumably) Jaunty. Give it a release or two for this wide testing (with self-selecting clueful users) to catch some of the really obscure corner cases that are undoubtedly hiding away in there. Then set it as the default the people who don't know or care what their filesystem is get.

To give you a rough idea. I have used ext4 on all my machines for a year and I have only ever been bitten by one bug. This one (https://bugzilla.redhat.com/show_bug.cgi?id=468437), it was non destructive not to mention fixed really quickly.

[SunnyRabbiera]

I hope ext4 is at least an option but should not be forced

[kestal]

I think ext4 will be great :) by default, on my end.

[jnw222]

not super stable for server, but interesting for the desktop users who want to use it.

needs to be added as an option, even if only available in an expert mode

[Gina]

I would by willing to test ext4 if/when it's available for testing in Ubuntu as an option. I have several PCs and not unduly worried if a test one goes belly-up - I'll just reformat and reinstall.

Obviously it should be optional, as is ext3 etc.

[michaeldadmum]

I think it should be an option when the user space tools (mkfs.ext4, fsck.ext4, grub2, etc.) are ready. I am already running grub2 and I will upgrade my / filesystem to ext4 first, then my /home filesystem after linux 2.6.28 is out.

I hope for the same, although I do hope there is a downloadable alternate ISO which has everything so even that can be tested.

but Ubuntu.....

For people who are running Ubuntu

For people who are running Ubuntu, it is *highly* recommended that you download a set of modified util-linux packages and install them. Packages for Ubuntu Hardy are available here. These packages revert a change made by Ubuntu to use the volid library instead of the blkid library. The volid library has a number of shortcomings, including that they don't work on freshly created filesystems or swap devices until after you reboot (since it is tied to udev probing) and the volid library doesn't understand ext4dev filesystems. The blkid library is much better, and Debian uses the blkid library for util-linux. Unfortunately, Ubuntu chose to make this reason for some unknown reason. For other versions of Ubuntu, the patch that was applied can be found here.

[decard_pain]

slightly off topic but did any one notice that btrfs(with dev tag) may be in kernel 2.6.29.so we may see that working right by end of next year

[autocrosser]

Yes, very troubling---I have sent a note to the developer-list about this topic & Plymouth--we shall see if that brings any movement......If anyone feels that writing to the dev-list can further the case...I would recommend it.

My note is as follows:

Thoughts about EXT4 optional in Jaunty Development & questions about Plymouth

I am active at ubuntuforums in the testing/development support area & there has been a fair amount of talk in the following thread: http://ubuntuforums.org/showthread.php?t=965879

As EXT4 has just been termed "stable", is there a possibility that it can be included as optional ? A use request/bugreport is filed at: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/197311

A fair amount of testing users (myself included) are ready to include EXT4 in their systems for testing use & I would think that this would be a ideal time in the cycle to testdrive the filesystem that I believe will be the standard within the next year or so.

On another topic:

There has been talk in the testing group about Plymouth & possible replacement of Usplash...IMO Plymouth provides a better user experience due to a "more" seamless blending of Grub, Kernel boot & GDM. I realize that there could be "issues" with this, but it could also net a more positive user experience .

Phoronix testing Ext4.....;)

http://www.phoronix.com/scan.php?page=article&item=ext4_benchmarks&num=1

9 pages !!!

Conclusion:

EXT4 is clearly a significant improvement over EXT3 when it came to the pure disk benchmarks, however, in the real world, saying better performance should not be used as a reason to replace your existing EXT3 or XFS partitions. In our tests that cater towards Linux desktop users and gamers, EXT4 hadn't delivered a sizable quantitative advantage. That's not to say though it's not worth switching to EXT4. EXT4 is more scalable, more efficient through the use of Extents, supports larger disk capacities, can handle twice the number of sub-directories, is capable of handling online defragmentation, and there is improved reliability via journal checksums. What perhaps is more important is that with the addition of these new features, the performance hasn't regressed. Also, when testing the EXT4 file-system, we hadn't run into any problems with stability, file corruption, or any other issues.

EXT4 is declared stable in the soon to be released Linux 2.6.28 kernel, but from there it isn't clear how big of a role EXT4 will play within the Linux ecosystem. Chances are we would see it be adopted officially by Fedora or another bleeding-edge distribution before it's used by default within Ubuntu or a commercially supported distribution. The development timeline for btrfs places a 1.0 release in Q4'08, but it doesn't look we'll see a stable release of that until next year. Depending upon how fast that file-system is hardened and what adoption rates it sees, it may largely influence how EXT4 fairs as a temporary alternative.


Still testing with one partition and a self-brewed kernel, also built it with 1000Hz and everything is "snappy"....:D

[druellan]

After reading Phoronix test run I'm convinced that EXT4 is called to be the default filesystem on any distro that takes seriously performance and speed.

Speaking of Ubuntu and since ext4 still on vias to be stable on Kernel 2.6.28, adding it as an option now seems risky and a waste of resources. There are plenty of things to improve on Ubuntu, specially on video performance and detection. But once the fs get tested no doubt is amust and should be the default fs for the distro.

[Slug71]

Anyone know when we can expect to see the Ext4 option in the installer?

[Starks]

I'd still like to see ReiserFS and Reiser4 as options. </sarcasm>

:3

[MacUntu]

Just something about file defragmentation with ext3:

- 15gb ext3 partition formatted for Intrepid
- no heavy use
- 38% free space
- created 10 80MB files

That's how they are spread over the partition [from the smallest block to the largest they use, each file a color]:

http://img.xrmb2.net/images/582328.png

I'm glad ext4 will have online-defragmentation and I'll try to repeat that "test" when I'll jump to Jaunty dev. :)

[Archmage]

Since the Kernel 2.6.28 ext4 is now official stable, therefore I'm really waiting impatiently to start testing it.

Could someone please inform us when we can use it? I would download the latest daily build as soon as I hear that it is there.

[Gina]

Tomorrow's daily builds of Jaunty will include ext4 as a partitioning option. As far as I can tell, it installs and boots fine (including full ext4 /; you don't need a separate /boot). I haven't tested resizing yet although I did add some code which ought to support it to the same degree as ext3, using resize2fs.

Dunno if we will get gparted 0.4.2 which has ext4 in this cycle.

[cjwatson]

I think that just means that that's what the gparted maintainer was testing with. gparted certainly doesn't have bits of the kernel built into it or anything (wouldn't that be a hideous layering violation!), so it's not really important that he was testing with an older kernel version.

[cjwatson]

Oh, disregard my last post, you were talking about the gparted live CD which of course does have a kernel built in.

I don't know anything about the gparted release schedule. The changes for ext4 are not entirely trivial but not all that complicated either, so they're potentially backportable in case 0.4.2 doesn't arrive in time.

[Gina]

Very interesting :) I'm hoping I can find the time to install an ext4 Jaunty at the weekend - looks like there should be a good chance of it working :) Thank you Colin (and others) for all your work on this :):)

Yep, thanks to you Devs who made this possible.

No but maybe we tries to eat developers...:D

[ShirishAg75]

bits of btrfs are slated for 2.6.29 release but the filesystem is supposed to take a year or more .

I saw the gparted trunk, most probably the devs will sync from the GNOME SVN.

Didn't know that the gparted guys had moved to GNOME (atleast for coding)

http://svn.gnome.org/viewvc/gparted/

i say this because I used gparted first time when it was a baby (0.1) from then it has come a long long way.

[LordVeovis]

Does anyone have a status update for BTRFS? I am really looking forward to this but their site has not had really any useful information added to it in a while. (at least not that I can find)

less off topic please, this thread is only about ext4 in jaunty.

Well, I converted my testing installs over last night---and did not leave myself a easy way out......To make a long story short, my boot partition didn't like what I did & thumbed it's nose at me........6 hours later & replacing a drive with a spare that just happened to have a much older bootable version of Jaunty on it---I'm now running Jaunty totally in EXT4. :)

Just glad that I thought to keep that drive I changed out a month ago.........:P:P:P

"Tomorrow's daily builds of Jaunty will include ext4 as a partitioning option. As far as I can tell, it installs and boots fine (including full ext4 /; you don't need a separate /boot)"

First ever post to a Linux forum so forgive me if I do something incorrectly or should be posting this elsewhere.

I installed Jaunty with this build. I used ext4 exclusively but did seperate /boot, /,/home,/usr,/var, et. al. into seperate partitions.

I made /boot bootable and left the rest with the standard default.

I gave /boot 500mb of space and the rest all received 40 GB except /home (which I allocated 100GB) and /data which I allocated the rest I believe. My swap is 6-12GB. /tmp wasn't allocated 40GB but was quite generous with it as well. I thought most of that would be overkill for space. Don't quote me on the /data as I do want to install other linux distros and may have left some of the remaining space unallocated.


Everything installed great. Unfortunately when I tried to login in, I keep getting incorrect user name and password. I know what I set as username and the password had to be typed twice to make certain there are no errors. So either I made matching typos twice or I errored in some other manner.

As a wild guess I wondered if it had anything to do with the way I set my partitions. I did read at first that when using ext4 one had to use a seperate ext3 /boot partion in order to boot. But when I read the quote above, I partially went with it and made the seperate /boot partion but with ext4. Maybe I errored here and either should have made the /boot ext3 or not made a seperate partion for it? Grub is 1.5. Seems I read somewhere that Grub 2 was necessary for boot with ext4?

I am semi new to linux obviously. :D

Still, I put together a cheap system for testing purposes. Thought I would try Jaunty. The testing system is an amd 64 x2 5000+ processor, asus m2n-mx se plus motherboard, 4GB corsair 800mhz memory, (2) 1 TB Hitachi sata HDs. Second HD entirely ext4 with /data as mount point.

If I did happen to make the typo errors for user name and password during install, is there any way to find out without blowing it up and reinstalling? If it is something else I errored at that is obvious to you pros, any help would be appreciated. Thanks.

Oh, I don't know what or if this has to do with anything but on boot I received a 8324 error. Don't quote me on the number but it had to do with apic/apci. I disabled it in Bios instead of putting noapic(sp) in boot up with grub. No more error. Could not use the wireless keyboard to install Jaunty as it would lock up at start of install. Still received the error message with standard keyboard but it did install. I disabled in Bios after install. Again, don't know if it has anything to do with my issue or not, but thought I'd mention the only error I did receive.

Why so many partitions??

Just need
Use Ext4 and mount as /(root) 40GB More than enough
Swap 2GB, 6-12 is WAY Overkill!!
Use Ext4 and mount as /home. 50GB More than enough

I'd maybe make a Fat32 partition too and mount as Windows which would be a shared partition and give it like 100GB. Linux can read and write to Fat32 partitions so if you have any more OSs on there they can all share that. Good for keeping files on there you may need in another OS.

Grub 1.5 is fine


Sweet test system though!

Well--You should cruise the forums a bit---normally to test or normal use--setup a / (root) partition & a /home partition--it is not needed or recommended to create all those /usr /lib etc partitions...creates a nightmare to install/admin your system that way.....a seperate /home will allow you to reinstall if/when the testing install "blows" up on you....Got to admire your guts to dive into a early alpha as a noob....I would normally recommend you get some time under your belt with stable installs first....And setting up with EXT4 is really for the advanced users right now.....

If you let system pic for ya it will make swap 12 GB on a 1TB hd.

I know most say 2GB but I think I made it 6GB. Still overkill I realize but got plenty of space to work with and figured I could try and change things around in the partion editor once I was in Gnome.

So many partitions---I had read it is more secure. Not that familiar with Linux security at all. Don't know anything about ipstables, apparmor, SElinux, etc. Thought I'd give the seperate partions a whirl. I realize I have the space for the seperate partions or the way you mentioned it.

I don't mind the nightmare. Gotta learn. ;) What could I possible learn from point and click? Setting up a /home, swap, /root only seems nearly as simple as it gets. I jump into a lot of things without knowing. Has been how I learn it seems. Heck I read things such as string theory for fun without any advanced mathmatical knowledge beyond algebra and geometry and minor experience with basic physics. lol
Complexity is the spice of life.

I do use Ubuntu on the computer I am at currently. Intrepid Ibex. Started out with version right before Hardy. Have played around with a few things.

I know one learns better when figuring out for oneself but that attitude got old.

I am not new to a computer nor am I incapable of learning quickly. I have had some networking courses in college at ITT Tech and elsewhere. I also have stayed at a Holiday Inn. :D

Just figured my question was a simple one to get answered without blowing it all up and reinstalling. But it seems the time I have spent writing and waiting for a response could have been spent reinstalling and I probably could have been mostly done with it by now. Still, if the same situation arose, I'd be right back at square one and searching around reading for hours for something that seems should be simple.

Not a problem---I started with UNIX in the early 70's, so I'm not exactly a spring chicken myself....The only reason I recommended the / & /home method is after you install/reinstall multiple times...it gets a bit tiresome to redo all those separate partitions (and a update/reinstall is murder--I've been there before)...and as far as security--well, just a / & /home is several levels above anything Windows can do.

About the partitions though, i think youre the first person ive come across that has used them all or had more than / and /home.
Nothing wrong with learning though. :)

Done, everything went sweet. Just made sure my Vista partition booted too.
Everything just seems to work with Jaunty.

Might of worked now though with os-prober but not sure and i didnt really feel like doing a reinstall. :P

Just got a very good reply from Scott Remnant about the underlying libraries that slowed the introduction of EXT4--makes some very good reading. You can follow the bug report/request at: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/197311

Scott's information really shed light on the reasons we are using the vol_id library instead of blkid & show the start of one library to replace both (I REALLY vote a +1 to get blkid functions in Ubuntu!!!).

I have also reported that there is a 3sec faster boot from grub to gdm in my system with EXT4--I encourage everyone to run bootchart--you need to have a good base of results before changing to EXT4 & try to run it within the same kernel to try & negate any other variables other than the change from EXT3 to EXT4.

As one of the aims of Jaunty is a faster boot--anything that shaves 3sec off boot is a very good start.........

[Gina]

I have just installed Jaunty with ext4 partitions for / and /home on an old desktop. This has a K6-2/450Mhz processor 256MB RAM and 8.6GB HD with very old SIS AGP graphics card. It's struggling a bit but it's working. I used yesterday's daily build Alternate i386 CD and manual partitioning. 3.5, 4.5 and 0.6 GB partitions for / /home and swap.

I think it's being hampered by low memory as it's using swap with very little running. I might be able to get more RAM into it from my P3 desktop which seems to be on the way out. Pity about the P3 - it's got a better processor.

what do you mean broken? Any screenshots or something about what happens when you try to do partitioning in ubiquity using daily.

Also has anybody tried using the alternate-installer, any luck with that anybody?

I used the AMD64 Alternate to install. Worked fine for me.
I had a DOS like screen all through setup and partitioning though.

You cannot use Manual partitioning...

Blow the whole disk is working...

I have 2 partitions I want to preserve, my old /home and my /media partition

Phoronix with a brand new test...

Yes for 64 bit but I am using 32 bit...

The text based manual partitioner works with the mini.iso and the alternate installer

sda2 is my system partition, also includes /home for a while, EXT4...

sda3 media which already was a EXT4 partition

sda4 is my old /home which I preserved as EXT3... I am a coward..


On sda2 I got my home now because I wanted a complete clean environment..

[MacUntu]

I have also reported that there is a 3sec faster boot from grub to gdm in my system with EXT4--I encourage everyone to run bootchart
No difference here but 2.6.28 boots a lot faster than 2.6.27. Some numbers for my 1.83GHz Core Duo, 2GB RAM notebook:

Intrepid, 80GB 5400rpm, EXT3: 28 sec.
Intrepid, 320GB 7200rpm, EXT3: 21 sec.
Jaunty, 80GB 5400rpm, EXT3: 21 sec.
Jaunty, 80GB 5400rpm, EXT4: 21 sec.

Damn, I didn't need that faster hard disk! :D Too bad I can't test Jaunty on the 7200rpm disk as I need it for my productive system.

[Gina]

Also has anybody tried using the alternate-installer, any luck with that anybody?32bit yes - 64bit no.

[Gina]

I'm hoping to have another go at installing a new Jaunty system on my AMD64. Alt CD won't work with CD or DVD so I'm goint to try the "install from Ubuntu" way (or maybe unetbootin). I have a working Jaunty system on my AMD64 using ext3 and I want to check out ext4. The Alt CD and manual partitioning worked fine on a very old desktop. So having got it going on my oldest working machine, I want to try it on my newest and best :lol:

I've been having that problem with the Live CD too.

Added to the bug report in Launchpad.

For Alpha 3 maybe I shall study QA for CD testing and Ubiquity.. this should just work, more then basic functionality, IMHO.

[ShirishAg75]

the master bug 310083was found and our bug was marked as a duplicate.

Would do a clean install only when this is resolved.

[Gina]

To check whether the "media change" problem was due to the host machine or system to install, I tried installing a 32 bit version on my AMD64 and it failed. This was the same CD I used to install Jaunty successfully on my AMD K6-2 machine.

I've added a 128MB RAM module making 384MB and it's made a big difference - it's now reasonable for that level of machine.

Hi all,
A new ubiquity is in the offing.



ubiquity (1.11.3) jaunty; urgency=low

[ Colin Watson ]
* Correct Bazaar link in debian/copyright, really this time.
* Update copyright years.
* Fetch subarchitecture in remove_extras (LP: #316446).

[ Evan Dandrea ]
* Fix the edit partition dialog by properly preseeding
partman/active_partition.
* Add support for encrypting the home directory to the gtk frontend.
* Automatic update of included source packages: apt-setup
1:0.37ubuntu8, partconf 1.30ubuntu1.

[ Mario Limonciello ]
* Reset random mysql password on every ubiquity mythbuntu invocation.
* Don't set anything in the mythbuntu_summary step.
* Transition apply-type code into python to be called directly from
mythbuntu_install.py instead.
- Along with this, handling for leaving files when not reformatting
/home should be fixed. (LP: #305236)
- Mythweb acl to SQL should be fixed now, but not necessarily
authentication.

Its building as we speak.

Update:- The i386 build is supposed to start an hour. Others as late as 17 hours from now. Few archs already done.

Those would be in the publishing queue

Please forgive me but what alternate AMD64-CDs will be able to create a ext4 at the installation?

(image of crossed fingers) The 15th "should" be Alpha 3

[Gina]

Well, up to yesterday, no daily builds of Alt AMD64 CDs have installed with ext4 (or ext3 for that matter) nor have I had any joy with the 32 bit version on my 64 bit machine. I'm not bothering to try again until Alpha 3.

Huh? Aren't delayed allocation and preallocation two key features that would even more reduce the likeliness of fragmentation compared to ext3...

[cjwatson]

If you're new to Linux, separating out your partitions so finely is probably just making trouble for yourself down the line, as you don't have the experience to know what a good split of disk space would be. (Personally, I do have the experience and I just use a single giant partition; life's too short to mess about with resizing and moving partitions all the time.)

It's not obvious to me what your username/password problem is, but I rather doubt that it has anything to do with ext4; I would suggest booting in recovery mode and resetting it. It's accessible from the GRUB menu.

[cjwatson]

I believe I fixed the "media change" problem today. (I couldn't reproduce it myself, annoyingly, but I did get one report that my semi-guesswork fix had done the job, so I'm hopeful.)

Seriously (and this goes to everyone mentioning installation failures here, though I know some of you did file bugs), please file bugs about installation failures. Even though I have trouble following all the bug reports that get filed, I have even less chance of following all the forum posts that get made! If you don't file a bug, you're betting that the problem is not specific to you and that somebody else will report it; if neither of those is the case then it's entirely possible that your bug won't get fixed.

With regard to installation failures, I operate mainly on noise. If lots of people are shouting about something, then I'd better go and have a look at it - however, that shouting does need to be in a place where I'll see it, which is more likely to be the bug tracking system.

[autocrosser]

Thank You Colin!!!

It's good to have you here....:guitar:

Oddly enough, these are major new features in ext4, which is also getting support for online defragmentation http://lwn.net/Articles/284529/

[MacUntu]

Oddly enough, these are major new features in ext4, which is also getting support for online defragmentation http://lwn.net/Articles/284529/
And having a defragmentation tool leads to "it requires too much defragmentation"? Sorry, that doesn't sound reasonable.

[Gina]

Thank you Colin from me too :) Will the fix make it to Alpha 3?

[MacUntu]

Are there any stress tools available (fsstress?) to test EXT4?

[blazemore]

The advanced users will all choose ext4. That gives them time to fix the bugs and iron everything out, so they can make it the default in 9.10, which is the idea I think.

where or which package has the fix ? Perhaps need to move to daily build of 17th January?

[spudgunner]

I'm interested in studying the ext4 source code to help me with a programming project in school. Does anybody know where I could download it from (and if it exists, a site that keeps track of code for multiple open source projects)?

[cjwatson]

https://launchpad.net/linux has the download links; grab the most current version, extract it, and look in the fs/ext4/ directory.

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git is the master revision control tree for the kernel.

As for a site that keeps track of multiple open source projects, that's part of Launchpad (https://launchpad.net/)'s purpose.

Thank you very much!

[zedx555]

I don't think GRUB supports EXT4 does it? It boots up but it is not officialy supported. GRUB 2 officialy supports it.

[MacUntu]

It does.

[cjwatson]

It's supported by Ubuntu's GRUB (Legacy) package, even if not by upstream.

[deepclutch]

Does a Ubuntu Intrepid on a ext4 is straight installable.does the kernel detects?should I need debian-installer based cd ?

[forcecore]

i always do manual installs only so ext4 exist for me and i chose ext4 by option.

[cjwatson]

Intrepid is not installable on ext4, and there are no plans to make it so.

[autocrosser]

Does a Ubuntu Intrepid on a ext4 is straight installable.does the kernel detects?should I need debian-installer based cd ?

Intrepid's kernel will not support it---you would need a 2.6.28 kernel. That would be the only limiting factor.

Wait a couple of months & install Jaunty at the RC release......

[autocrosser]

Greeting Colin!!!!!;)

[cjwatson]

No, it would not be the only limiting factor; there were several other components that needed small tweaks in order to support ext4.

[forcecore]

Intrepid is not installable on ext4, and there are no plans to make it so.

but in manual mode it is or not? so far alphas was insallable with ext4 on manual mode.

[cjwatson]

I repeat that Intrepid is not installable with ext4, regardless of whether you use manual or automatic partitioning. Jaunty alpha releases are installable with ext4; that feature was added well after the release of Intrepid. We do not intend to backport it.

He says it not possible to install Intrepid on an EXT4 partition... not that is impossible to switch an Intrepid install over to ext4 via updating the kernel/booting off a liveCD

[Kow]

That's not true either. The 2.6.27 kernel does support ext4, but I don't know if it should be trusted.

[cjwatson]

I'm sure you can make it work on something that started out being Intrepid if you try hard enough (it's all just software after all), but it won't work out of the box in any reasonable meaning of that term. In Intrepid's 2.6.27 kernel, it's only available as ext4dev; klibc doesn't have the necessary patch to let you boot off it; the module isn't copied into the initramfs; the installer's partitioner has no support for it; and so on. Obviously you can do anything with software if you try hard enough, but my statement is still true for most people.

(I'd also think twice before risking it given the ext4dev status, myself; but I'm not a filesystem developer.)

[deepclutch]

interesting :) .If I compile a custom 2.6.28 kernel(latest) with optimizations and with built-in ext4 support on Intrepid - Then ,Can I do a mirror(dd) of the current partition to a new ext4 partition created ?(ofcourse ,with new kernel).I would like to know.thanks.Already e2fsprogs is 1.41 in Intrepid.

Is there anything I am missing ? :confused: ;I had already tried such kind of copying of installation from failing hdd's(where ,the transfer sometimes cease temparorily).Only thing ,I found difficult is ,some files/permissions(like suid bit etc messed out) problems ,which ,can be solvable .

[cjwatson]

It's all theoretically possible, but if you're going to mess about with this then maybe you might as well just use Jaunty ...

[Starks]

I'm getting "no space left on device" messages at least 5 times a week and they don't go away until I do a fsck from a livecd/liveusb environment.

[forcecore]

I repeat that Intrepid is not installable with ext4, regardless of whether you use manual or automatic partitioning. Jaunty alpha releases are installable with ext4; that feature was added well after the release of Intrepid. We do not intend to backport it.

sorry if i posted i wanted to say jaunty manual mode not intrepid.
