@THCTLO and all, is there a type of SSD that works better for you?? For me, kernels 3.13, 3.19, and 4.2 (all variants of linux mint 17.x) create this issue with intel SSD drive 460GB. Extremely annoying because windoze 7 worked like a beast on this drive for over a year and I just migrated the disk to run linux in another pc...

[Bug 992424] Re: ext4 filesystem errors on SSD disk
Wife has a U300s running Debian Mint. Got bit recently w/ custom 3.5.2 (standard .config updated with defaults and compiled). I'm compiling 3.8.4 on it now (again debian mint standard .config updated w/ defaults for 3.8.4) to see if that fixes it. Filesystem is ext4. I know I'm on ubuntu launchpad web site versus mint/debian/upstream but read through the problems here. Wife says system never ran on battery to battery death (I asked). However she likely suspends the system every evening. Don't know if that triggered the file system corruption. I'm frustrated (calmly so) and wondering whether JFS or bleeding edge kernel or ? what ? will fix. This is the only SSD in my house (of 5 house computers) and the only computer whose file system trashes this way. As a U300s (will never buy again) you cannot pop in a standard replacement SSD (non standard SSD). Again, hope this adds some insight.

[Bug 992424] Re: ext4 filesystem errors on SSD disk
Since I've been running days longer than previously (since the trouble started at the star of October) with no errors at all, it seems to have been a hardware problem. (One can imagine software problems that depended on an odd structure in the original file system, and I didn't copy the file system bytes: I copied its files into a new, empty file system. Even so, that possibility seems unlikely.) I don't think it was a fundamental mismatch between device and software, since I've had the SSD in the machine for about two years without fuss. I've got two remaining questions: what was the actual hardware error, and why did it not show up as a hardware error to the software (or if the hardware did try to signal it, why didn't the software diagnose that right away)? I've kept the old SSD, and when I've got some spare time I hope to experiment with it in another system, to see whether it misbehaves there, undetectably. It's tricky to do experiments with a device and a system that are being used for production (ie, paying) work.

[Bug 992424] Re: ext4 filesystem errors on SSD disk
I wondered whether ext4_mb_generate_buddy might be related to http://help.lockergnome.com/linux/ext4fs-error-ext4_mb_generate_buddy-741-group-16-8160-cluste--ftopict559576.html so for a final experiment, I've switched off discard once more. That bug seemed confined to scsi_debug, but who knows? On the other hand, another round of fsck -c -c -k found 3 more bad blocks, once again in the journal. Note that fsck -c -c -k has got a problem: it adds the blocks to the bad block list, and promptly complains that there are duplicate blocks in the bad block inode and in the journal. It then asks whether to clone the multiply-allocated blocks. Unfortunately, it gives no sign how it will clone them: will the bad blocks remain in the bad block list, with the copies going into the journal, or will the blocks remain in the journal, with copies uselessly being placed in the bad block list. I decided it was safer to delete the journal, re-run the check, leaving the blocks only in the bad block list, then recreate the journal, then switch discard off. The bad blocks were as follows: (0-2):2277409-2277411 (3-5):2277665-2277667 The pattern is easier to see in hex, I think: 22C021 22C022 22C023 22C121 22C122 22C123 Hmm. 3 in a row each time. 256 might be important in the internal geometry. *Might* be a failing drive. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/992424 Title: ext4 filesystem errors on SSD disk To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/992424/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Since my usage doesn't seem to be that unusual, and if anything is fairly light, and many people these days would be using SSDs with Ubuntu, even Ubuntu 12.04, I'd assumed that if there were a bug that was causing frequent corruption of [file systems on] SSDs at the rate I've seen, there would be widespread reports of dismay, but that doesn't seem to be so. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/992424 Title: ext4 filesystem errors on SSD disk To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/992424/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 992424] Re: ext4 filesystem errors on SSD disk
I was wrong about that. fsck -c -c -k ... had found 3 bad blocks, so I thought ah! it was device error after all. Having moved the bad blocks out of the way, I expected all to return to normal, and would have changed to moaning about the complete lack of visible diagnostics (including in dmesg) about the occurrence of any IO error when writing to the bad blocks. (It's possible that the IO ends up in the device cache and it's not until that's flushed to the drive that any error is detected, and that's not communicated back to the host, so there's little the software can do.)

Since I get problems anyway, I've enabled discard again. I might be willing to believe my SSD has hardware problems or is wearing out, but I've seen trouble on two different systems so far. Also, int February, when I had corruption with ext2/3, I thought it might be memory or SSD, but memory tests went fine, and then it happened on a conventional SATA drive as well on a different machine. I changed those machines to ext4 (since that seemed more actively maintained, and the diagnostic I was getting related to a known race in ext2/3), and ... the problem went away until last week. There have never been relevant errors in the drive's error log (SMART). I could change over to a replacement SSD I bought in February, but it's a bit of a slog that won't work if there really is a driver problem somewhere. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/992424 Title: ext4 filesystem errors on SSD disk To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/992424/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 992424] Re: ext4 filesystem errors on SSD disk
With ThinkPad X220 and 240 GB Intel 520 SSD I also get serious filesystem corruption errors running Ubuntu 12.04 desktop. Serious means: just now I couldn't boot from the Ubuntu partition on the SSD; I had to boot from another disk and fsck the Ubuntu partition on the SSD, and even then the booted Ubuntu 12.04 system behaves erratically, indicating file corruption has occurred. Until I figure out what is going on I have gone back to running Ubuntu 11.10 from my trusty old Hitachi hard disk. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/992424 Title: ext4 filesystem errors on SSD disk To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/992424/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 992424] Re: ext4 filesystem errors on SSD disk
I'm experiencing similar file system corruption issues with my Sandisk Extreme 120GB SSD. All Ubuntu or Debian based Linux OSes I tried so far, including Ubuntu 12.04, as well as Fedora 16 and 17, report file system errors on bootup irregularly. After fsck and fixing the errors (or in case it boots normally), I get various segmentation faults and/or CRC errors for files. Trying 5 or 6 different distributions with the same results, I must conclude this may be a kernel issue. I will update my SSD firmware in the hope that this solves the issue, but I doubt since the updated firmware supposedly only addresses TRIM issues (discard option in fstab). All distributions worked perfectly fine when booting them from a live USB stick. I checked my RAM using memtest86+ and it reports no errors. Also smartctl does not reveal any problems with the SSD. I managed to install and boot several 3.2 and later kernels from SSD, but when using synaptic for updates and installs I eventually get segmentation faults for synaptic, or the system doesn't boot anymore. It looks like something is corrupting the file system. Again, this happened with all new linux kernels 3.2 and above (see above list of distributions I tried). I do not have any issues with the SSD while running from a live USB stick. I can format the disk, install on it, chroot into it and install or modify things, but I can't get a stable system booting from the SSD. One of the common errors when the SSD doesn't boot is efidisk read error. But it also doesn't work with MBR formated SSD. I wonder if SSDs can be used with kernel 3.2 and above? I didn't try older kernel versions, though. Sorry I can't post more specific details, but if anybody is interested to get output of debugging commands with Ubuntu 12.04, I will try. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/992424 Title: ext4 filesystem errors on SSD disk To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/992424/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report at bugzilla.kernel.org [1]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug. If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.4kernel[1] (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed.
