[Bug 330824] Re: Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28
I have experienced a similar bug removing largish video files (about 4GB or so) from an internal SATA drive formatted with an xfs filesystem. Sometimes when doing an rm -rf on a directory on that file system, the rm will hang and remain pegged at 100% cpu usage. As opposed to other posters in this thread, I don't see any suspicious messages in dmesg about hangs or timeouts, and usually I'm able to rm -rf the directory in question from another terminal session without a hang. The only thing that kills the rm is a reboot, kill -9, Ctrl-C and so on all won't work on that process. Please let me know if you need any further logs, I'm running kernel 2.6.32-27-generic #49-Ubuntu SMP Wed Dec 1 23:52:12 UTC 2010 i686 GNU/Linux on Linux Mint10 which is based on Maverick 10.10. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/330824 Title: Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 330824] Re: Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28
It seems like the fix has been released for this but I am still having this problem. I can copy large files (around 15-20 gig) to a NTFS hard drive and there is no problem. However when I try to copy same files to an internal hard drive which uses ext4, the system freezes. I am using Karmic with kernel 2.6.31-16-generic. My question is, how do I get the fix? I get auto updates but do I have to manually install the fix? And where is the patch files are located?

However when I try to copy same files to an internal hard drive which uses ext4, the system freezes. This would be a different bug, as this bug only occurs when removing files. My question is, how do I get the fix? It looks like the latest karmic kernel release is 2.6.31-17. You might want to try installing that. If that doesn't work, and assuming that it really is a kernel problem and not caused by something else, you could try the 2.6.32 kernel from lucid's repository, though since lucid is still in alpha stages, it might be best to find out if it really is being caused by the kernel first. -- Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28 https://bugs.launchpad.net/bugs/330824 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

actually I'm sorry, I take that back. I was trying to rm -rf over 1.3TB of data, composed of over 17,000 sub directories each a dozen or so files located inside. I too had complete system lock-up when I would try deleting them (moving and copying was fine). I tried to move the directories in blocks of about 100 or so to another directory, then tried deleting those. I had the same lockup issues. The method that taigolp proposed helped a lot, but didn't completely solve my problem.While I could delete about a 100 or so directories now, I still can't delete the entire 17k directory tree without a full lock-up. for the record, I'm running jaunty 32-bit, 2.6.28-15-generic. ext4 native on a LVM volume spanned across two 1.5TB sata drives on a silicon image SATA pci card. -- Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28 https://bugs.launchpad.net/bugs/330824 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

At this point, it seems pretty clear to me that no one is really working on this for Jaunty; if you must use Januty, the only thing I can suggest is to use a mainline kernel --- any mainline kernel, whether it is 2.6.28, 2.6.29, or 2.6.30 will work fine. The problem seems to be in Canonical's backports of patches to the 2.6.28 kernel, and the only people who could work on it are busy working on the Karmic release and/or the Karmic kernel. Those of us (like myself) who are working on the upstream ext4 are busy working on the latest set of improvements and bug fixes that will go into 2.6.31 or 2.6.32. For those of you who need some proprietary drivers, I'm sorry to say, the only thing you can really do is wait for them to become ported to the Karmic kernel (or port them yourself). -- Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28 https://bugs.launchpad.net/bugs/330824 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This sounds similar to a problem that I experienced yesterday. I did a fresh installation of Ubuntu 9.04 recently and formatted every partition to ext4. Yesterday, I was moving huge video files from my home directory to a removable USB hard disk (formatted to ext4 as well) when the system froze permanently (i.e. all hard disks stopped running completely). I did this with a couple of my other removable USB hard disks and the same thing happened many times. The problem can be replicated by copying or moving files within the same IDE hard disk as well. Just a while ago, the system froze when I emptied Trash. The computer has Windows XP installed, and no such problem problem occurs when I'm running it. However, as far as I know, I have not experienced any data loss. With reference to a few of the comments made above, I have more than 40Gb on every partition at any time, so the locking up seems unrelated to the amount of free hard disk space that one has. -- Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28 https://bugs.launchpad.net/bugs/330824 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Full acknowledgement! For me, I installed Kubuntu Jaunty fresh with native ext4 and external backup drive, also ext4. Actually it was because of a system crash in which I lost my complete partition. So I want to have the backup-system working now before I proceed! But I was stuck because of this ext4-bug, system freezed very often! I'm just a user and didn't want to experiment!!

So I decided to tweak the system and get the kernel 2.6.29 (the 2.6.30 seems to have other problems..), following: http://www.ramoonus.nl/2009/03/24/linux-kernel-2629-installation-guide- for-ubuntu-and-debian-linux/ But this doesn't put it in GRUB, so you have to change your menu.lst and do update-grub and update-initramfs. Well, no crashes so far, even copying about 30gig. I actually removed the nodelalloc mount option, still stable so far. I really recommend to get a newer kernel ( =.29), especially because this is just an Ubuntu problem and Ted Ts'o is probably busy fixing more important stuff :) But the ubuntu guys should provide indeed an automatic update for the _really_ unexperienced people! -- Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28 https://bugs.launchpad.net/bugs/330824 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 330824] Re: Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28
I've also been using the Karmic kernels on Jaunty (and the new nvidia drivers) as suggested by martinm1000. Unfortunately, it seems to require also updating the graphics drivers, in my case nvidia. I've applied this temporary fix a while back, seeing this is taking too long to fix. I also vote for a backport as a temporary fix, instead of having inexperienced users jump through hoops. Most of the solutions posted so far seem to mess with your 3d acceleration, either requiring an update to the video drivers or manual installation. Another reason why i think a backport would be preferred. I understand package policy would make it difficult for kernel 2.6.29 or newer to make it into jaunty. But isn't that what jaunty-backports is for? Using mainline kernels or getting karmic packages is not exactly a 1 click installation, and in fact could break your system. A backport on the other hand can be enabled using the GUI. And could provide an easier fix for those who need it. The solution i adopted is very similar to having a backport: 1) Add a pin, by editing /etc/apt/preferences Package: * Pin: release a=karmic Pin-Priority: 50 2) Append karmic to your sources.list: deb http://us.archive.ubuntu.com/ubuntu/ karmic main restricted 3) Update your repositories. sudo apt-get update 4) Use apt or synaptic to get the packages you want. linux-image-2.6.31-3-generic linux-headers-2.6.31-3-generic linux-headers-2.6.31-3 nvidia-glx-180 nvidia-kernel-common -- Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28 https://bugs.launchpad.net/bugs/330824 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Installed linux-image-2.6.28-14-generic 2.6.28-14.46 from jaunty- proposed. Ran hang.py, and still obtained a soft lockup. Doesn't seem like the update fixes this problem.

We might have a break in this bug. For those people who can reliably reproduce the problem, are you using ecryptfs, possibly extensively? Roland Drier has reported a potential lockdep report that might explain why some of us have had extreme problems reproducing the problem; namely we might not be using ecryptfs. See: http://lkml.org/lkml/2009/7/4/93 If so, there is a sample patch which **might*** fix this problem. See: http://lkml.org/lkml/2009/7/5/79 Also, if people could try building their kernel with CONFIG_PROVE_LOCKING, that would be interesting to see if we get a lockdep report. If so, it might be that this bug has been around all along, but it's something about Ubuntu patches that makes it 100,000 times more likely to trigger. (In practice, it looks like it should only trigger on a truncate to a size which is not a multiple of the filesystem blocksize, not on an unlink --- but maybe there was a bug in the Ubuntu backports that made this possible to trigger on an unlink. This is only a theory, but it's the first lockdep report I've gotten that could at least potentially be related to this problem that to date, only Ubuntu users have been complaining about, even though at this point we've got a huge number of Fedora 11 users using ext4 w/o any problems.) -- Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28 https://bugs.launchpad.net/bugs/330824 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

At that time, (during the beta of Jaunty), the most common use case that triggered the bug was the running of multiple Virtualbox virtual machines WHILE simultaneously moving/deleting files across/from multiple partitions. I must note that, over the last two and a half months, I have had a relatively stable experience with Ext4 on Ubuntu. My Ubuntu laptop sees lots of daily use, and I have only had about five lockups (which may not be the fault of ext4). I still use Virtualbox - although not as much. I still move files around - but not as much. The more recent freezes have all occurred when I have a few large projects open in Eclipse and I am doing an ant build outside on the commandline. The builds and projects are usually large enough to cause a bit of memory pressure (and swapping) on a laptop with 4GB RAM. I am no filesystem expert - so I don't know if this information helps or just clouds things up further.

However, the problem Roland reported could very well lead to a deadlock in the truncate path, which is very much related to the problems are reported. The only way the problem Roland's potential deadlock could be related to this is if there is a bug in the Ubuntu ext4 backport such that the truncate code thinks it's only doing a partial truncate in the case of a delete. But we it seems pretty clear that there was a bug in the Ubuntu backports of various ext4 patches, so the one-line patch which I suggested might actually make things better. - Ted -- Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28 https://bugs.launchpad.net/bugs/330824 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Otherwise a bug that makes e.g. xournal completely unusable would be low priority. Instead it must be high priority, it's high in xournal, not in ubuntu. Likewise, the medium designation for a bug that deadlocks the kernel seems a bit wrong also in my opinion. It should be high in the kernel.

[Bug 330824] Re: Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28
I registered just to say that I have been seriously affected by this bug, and it certainly deserves more than the medium designation. Single core, ~1GHz processor, would deadlock consistently on rm -rf'ing a directory of photos (~4MB each, thousands of them) using the stock ubuntu kernel 2.6.28-11 (then -.13) on an ext4 filesystem (native), LVMed and RAID-1. All of the LVM RAID overhead might have exacerbated the bug if it was a race condition. I love Linux in general, and have been very happy with the hands off safe, stable feel of Ubuntu distros, but this latest install was a freaking disaster since I primarily use this machine remotely. If EXT4 was known to be so unstable, it should have been marked so. Since the bug has been known for months, and people have offered to ship pre- installed machines that can reliably reproduce the problem, some more progress should have been made. Admittedly, it's tough to bitch when I haven't done anything to help fix the problem, but seriously I would be much happier if someone just upgraded the bug status from medium. I've gone to the mainline kernel 2.6.30 and I had to install the newer 180 version of nvidia drivers in order to do so. Very helpful directions for how to do this are given here: https://bugs.launchpad.net/ubuntu/+source/nvidia-common/+bug/384639. After the switch to the mainline kernel, no problem with the mass deletes. I highly suggest that anyone having this problem do the same. These directions should be linked on the main Ubuntu Jaunty page. Releasing with ext4 (without any sort of cautionary warnings in the installer!) in this shape was a serious mistake.

While I can definitely understand your frustration, please keep in mind the context of your issue. Ext4 is not the default file system so it only affects a small minority of users. See https://wiki.ubuntu.com/Bugs/Importance for more information. I am not sure if this would qualify as a severe impact and it is already fixed in newer kernels as you noted. Also this isn't affecting all ext4 users, as some people on this report including myself are unable to reproduce it and have had absolutely zero problems with ext4.

If EXT4 was known to be so unstable, it should have been marked so. As others have said, if you want the most stable release, go with the file system the OS recommends. The fact that it isn't the default should in itself tell you it is believed to be less stable. The overall stability also was not fully known, which was the point of including it as an option in 9.04, to get testing and learn about important bugs like this so they can be fixed.

We just must keep in mind the perspective of what we are doing as testers, testing early software, and understand that sometimes it IS going have issues and not to use it for production environments or systems which need to be stable.

[Bug 330824] Re: Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28
I want to apologize for my last comment. I really like having a free operating system and all the free software, and I love the people who volunteer their time putting it all together and making it work as well as it does (thank you!). I was in a bit of a mood after messing with this thing all night. I use Ubuntu because I am lazy. I don't go out of my way to install the newest cutting edge stuff because I would rather not be the one who spends his hours sifting through these forums / the source / git bisect / etc. I'd rather benefit from the hard work of the people who like to do that stuff (thanks again!) So once every year or so, whenever I get a new drive or update some hardware in some significant way, I go to the Ubuntu website and download the latest installation image, and usually only after it's been out a few months. With minimal faffing I have my system up and running in half an hour or so, all my old data happily copying over to the new system. I never read release notes, things just work (well, laptops usually need a little tweaking). I had no idea this last time that when I installed 9.04 that selecting ext4 was in any way dangerous or experimental. Deviating away from the stable defaults that Ubuntu provides was as easy as cursoring up (or down, I don't remember) from ext3 to ext4. I saw the option, thought to myself, cool, it's here, this is Ubuntu, it must be working well why not use ext4 vs. ext3? I had no idea that I was doing something even slightly risky, because there was nothing in the lazy man's path from download to having a running system that would have told me so. If there was, I would have gone ext3 and I never would have read this thread and you wouldn't be wasting your time reading this right now. From now on, I'll read the release notes and hopefully save us all some time. I'd like to be more lazy, but there simply isn't a better option than Ubuntu right now. So lazy talk aside, I'd actually like to be more helpful when these things come up. This particular case looks (from the tiny bit I have seen) like a classic deadlock. In the codebase I am most familiar with, it's pretty simple to turn on traces for locks that you know are in contention and use the trace to find the culprit. It's been almost ten years since I've done any significant work in the Linux kernel, however, so I'd have to do some ramping up. Anyone have pointers to your favorite kernel hacking resources (I'm sure even the basic tools have changed a lot in 10 years) in case I find myself motivated and with some time on my hands?

However, I am operating two very different machines (no two pieces of hardware the same) with the same operating system (Jaunty [ext4] with all the latest updates). Both machines exhibit the same 'freezing' problem on deleting files and the effect is random with seemingly no preference to size or number of files being deleted. As an engineer I hate to give qualitative (versus quantitative) comment, but I have noticed that the frequency of system freezes has increased roughly threefold (conservatively) in the last few weeks, particularly since the move to 2.6.28-13 from 2.6.28-12. For the first time in 30 years I am having to modify my software to have it not delete temporary files just to avoid the operating system hanging... madness! Dare I say I cannot remember Windoze ever having a bug this bad; I think this one needs nailing fast gang. -- Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28 https://bugs.launchpad.net/bugs/330824 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

If you need your computers to be stable, then there is no-one stopping you from using EXT3, which is rock solid. EXT4 is not the Jaunty default fs and warnings about EXT4 are clearly available in the release-notes: http://www.ubuntu.com/getubuntu/releasenotes/904#Lock-ups%20when%20deleting%20files%20from%20ext4%20filesystems My advice: don't jump on EXT4 until Karmic.

[Bug 330824] Re: Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28
Regarding Øyvind's wise words... I completely agree Øyvind and you are right sir. That said, there are an awful lot of people (like me) who have opted for ext4 believing that any major bugs would be sorted in the usual timely fashion that we have come to enjoy from the Ubuntu community. I think in retrospect ext4 should not have been offered as an option because it is just 'too tempting' to either take the option at install time or follow the procedure for upgrading from ext3 to ext4; you only have to look at the plethora of posts in this and other fora to see how many folk (a lot of them newbies to Linux and/or technically weak) were and still are desperate to try out the new FS because that is a normal human trait. I can live with the bug or go back to ext3 and wait for KK; my post was not really about me. My real point is the damage to reputation and trust that something like this has with the public at large, particularly those 'converts' from Window$ who maybe are not as technically minded as us (and use such fora as this to research what is going on) who will 'bad mouth' Linux/Ubuntu and got back to Windoze for all the wrong reasons. My personal advice... either the bug gets fixed in a timely fashion or a much stronger warning is issued (including taking the option away to opt for ext4). Please be assured of my best intentions... Ubuntu is king in my book!

Yep, and it was not my intention to be rude either. But at the risk of sounding a bit harsh, I'd say that comments like «this should be fixed NOW because it ain't working» also don't help. But I certainly do understand the frustration that many EXT4 Jaunty users must be having wrt. this, and I think this bug is grave. I initially had all three of my machines converted to EXT4 when upgrading to Jaunty. But after observing this bug report for a few weeks, I quikly realised the dangers and converted about 13 partitions on 5 disks back to EXT3 :). My reason for replying was that Nicholas Roberts stated that he was modifying his software to work-around Jaunty EXT4 bugs.

Well said Andri. Now back to the bug. I have been running 2 entirely different servers with the desktop version of 9.10 for 3 weeks now with EXT3 and other with EXT4. In 8.10 and 9.04 Ubuntu froze as described above when I deleted large numbers of files. Or indeed when any software deleted anything (eg Sabnzbd, newsleecher etc) However I upgraded the Kernel on one server as recommended and upgraded to 9.10 on the other and the problem hasn't shown its ugly head in three weeks. Whatever the problem is it isn't restricted to EXT4. So whatever is in the new kernel or 9.10 is working and should be brought to 9.04. If like me your not a huge Linux tech and looking for a quick easy fix from 9.04 press ALT F2, in the box type update-manager -d and press run, in the next window click upgrade. -- Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28 https://bugs.launchpad.net/bugs/330824 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Yes the bug is fixed in Karmic, but in development releases many many worse bugs can be found (especially this early).

Re: [Bug 330824] Re: Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28
Hi There is a better solution as suggested before in the discussion. Download 2.6.30 from here http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/. I never had a problem after installing mainline. I wont recommend it if you are using some proprietary drivers from Ubuntu. They may not be supported. My / is not on ext4 though but all other partitons which I used for storage are on ext4 now and I was having problem with stock jaunty kernel.

[Bug 330824] Re: Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28
Another possibility is to use the Karmic kernel but keep a Jaunty userspace. I haven't tried this myself, but I suspect it is highly likely to work. As far as people complaining --- please note that (a) Ubuntu has not made this the default, and (b) when I talked to the Canonical kernel team, they were using ext4 and very happy with it; they weren't seeing this problem; (c) I've not been able to reproduce the problem, even using some of the Python reproduction scripts provided here, on a 1024meg Atom netbook running Jaunty. It may be because I (and the canonical kernel team) don't run some critical program which is needed to enable this bug to trigger. (d) From working with the people who *can* trigger this bug reliably, it seems to be related to the Ubuntu specific backports of ext4 patches; if those 10 patches are removed, the system is stable. With *any* upstream kernel, either before, after, or at the Jaunty snapshot, these problems don't show (at least for the people who have done testing for me and who are able to replicate bug --- as I've said, I can't reproduce it all on my systems). As far as jagnet's report that he sees hangs when deleting large number of files using ext3 with the Jaunty kernel --- that's interesting. I don't know how to square that with people who took the stock kernel at the Jaunty snapshot point, saw that they had no problems, applied the Ubuntu-specific ext4 patches from the Jaunty sauce (aka 'value-added' distribution patches) and then were able to reproduce system hangs when deleting files. In any case, I'm a volunteer, and I do ext4 development largely on my own time. I'm not paid to support Ubuntu.So I have to ration my ext4 late-night development hours carefully, and there's been a lot of need of my time to get fixes and support for 64-bit e2fsprogs in upstream. And unfortunately, there is no paid Ubuntu resource supporting ext4, at least as far as I know. Eric Sandeen, on the other hand, is a Red Hat employee, who has spent a *huge* amount of his time (both paid and personal time) helping to make sure that Fedora 11's ext4 was rock solid stable. As a former SGI employee employed to work on XFS, he's extended the XFS test suite to work on ext4, and we're using it to make sure that the upstream ext4 is rock-solid stable, and he's been using it to make sure F11's ext4 is highly stable. I'm sorry I can't spend more time working on Ubuntu's ext4, but at the end of the day it boils down to time management --- especially when there are workarounds such as using the Karmic kernel or using upstream kernel. I'm sorry for those of you using proprietary drivers, but there's a reason upstream kernel developers aren't terribly fond of such things. -- Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28 https://bugs.launchpad.net/bugs/330824 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Ulrich: Are you sure none of those operations involved deleting files? The usual symptom is that the system hangs *after* the rm is successful, so that's not out of character. SVN does some amount of file-based locking, IIUC, which means at some point it has to rm the lock file. Creating a tarball shouldn't remove anything - but surfing the Web may very well, if the cache is full and it has to start clearing out old entries. And I know that it's not in *all* cases that heavy load is important - as I'm encountering the bug, ANY rm freezes the system every single time. @DanielV: Are they on the same volume?
