    Phoronix: There Might Be Another EXT4 Corruption Bug

    It was only days ago that an EXT4 file-system corruption bug affected the stable Linux kernel, which was finally patched yesterday. Now though it looks like there may be another EXT4 corruption bug affecting the stable kernel...

    Scary

    ext4 is supposed to be mature, reliable and well tested system today.

    It is scary with so these file corruption bugs lately.

    Luckily this one is reproducible so hopefully it will soon be fixed.

        More important, i always reformat the HD when install a new Linux and NEVER upgrade a distro (as in: from 12.04 to 12.10 or 13.37 to current)

        There is nothing like a fresh start.....


        OTOH, i'm starting to get fed up with EXT4....any other FS recommended that is more stable, corruption free and if possible, faster ?


        TIA,

          1. Format and label a target Ext4 partion using Ubuntu 12.04
          2. Install 64bit 12.10 OS using that target without reformatting it
          3. Shut down
          4. Boot an alternate copy of Ubuntu
          5. Restart selecting the newly installed OS
          6. Login then shutdown
          6. Boot an alternate copy of Ubuntu
          7.Fsck the newly installed OS allowing corrections to be made
          Why would anyone do that?

            So much bullshit in one single post. First: I'm happy for you if you format every 6 Months. You are the future. Second: stick to Ext3 as it has a long history when compared to a baby like ext4. I'm also not sure how can you be fed of Ext4 if you never encountered the bug described in the this post or in any other one.

              If he was just helping out doing some extra testing, I'm genuinely impressed!

                So much hasty conclusions (and bullshit) in one single post.

                If you read previous posts from me you would know by now that i use SLACKWARE as my only distro (i do install other distros in another partitation for testing purposes but don't use them in a regular basis, hence my reference to 12.04 to 12.10) ....SLACKWARE , as opposite to CRAPBUNTU is not "replaced" every 6 months....

                As for EXT4...
                Actually i encountered corruption in EXT4 in the past and last weeks news about a new surge of bugs made me remember "good old times" about it....these events in last weeks are not 1st time that EXT4 is hit by serious corruption bugs.


                So, besides going back to EXT3, any more good alternatives ?

                  As far as I know, ZFS is the only usable alternative available that provides solid data integrity guarentees.

                    Well, he forgot a few steps:

                    8. Pull hard drive without shutting down computer.
                    9. Throw hard drive at wall.
                    10. Krazy-glue "alternate copy of ubuntu" to hard drive, and hook up to car battery.

                      Thanks, i will try it in my nest build....i might need to build a Linux box around a mini-ITX MB sooner than i thought and will use ZFS on it...

                      Is ZFS by any reason slower than EXT4 ?

                      Data integrity is a must but i would like to know if there is a speed penalty if i also use it in a gaming rig....

This, being open source, we see bugs like these daily and you get the impression that ext4 is shit when it's actually pretty good.
                        +1

                        In Window$ we download patches for what we even haven't a clue for what they are.....and yes, one of the several reasons i dropped Window$ was data integrity because several times some games locked my rig and only way to switch off was to hard reset making data corruption....

                        Alt+PrtScrn+REISUB is our friend

                          some of use like to use software from current decade... It's not like even basic software is feature complete (for example: pdf readers)

                          You use only emacs/vim with ratpoison on 4-5 year old hardware, good, I'm sure it works great for you and not having software updates, beside security stuff, is not a problem. But I've got news for you: not everybody has the same needs.

                          BTW: Ubuntu upgrade process is quite solid (compared to Windows, it's rock solid), so you're really barking up the wrong tree.

                            I'm a software developer myself and I'm all for testing software. But in this case, I've to agree with dsmithhfx.

                            At some level most software will fail. And that 'testcase' consists of so much bullshit that throwing the hard drive against a wall is exactly on the same level.
