Running an ext4 RAID0 with a Linux 4.x Kernel? Better Spray for Bugs

The combination of RAID0 redundancy, an ext4 filesystem, a Linux 4.x kernel, and either Debian Linux or Arch Linux has been associated with data corruption.

El Reg reports EXT4 filesystem can EAT ALL YOUR DATA

Fixes are available, one explained by Lukas Czerner on the Linux Kernel Mailing List. That post suggests the bug is long-standing, possibly as far back as the 3.12-stable kernel. Others suggest the bug has only manifested in Linux 4.x.

[...] This patch for version 4.x and the patched Linux kernel 3.12.43 LTS both seem like sensible code to contemplate.

    On topic: I love this headline.

    Offtopic:

    Instead of an "Original Submission" link prominently displayed, can we hyperlink the word(s) after the submitter's ID?

    [submitter name](link to their profile) [writes/tips us about/suggested we cover/etc.](link to original submission)

    This is both cleaner and more intuitive - it's where I'd look for the story directly attached to the submitter.

    We are trying to automate the system and the quickest fix is to place the link at the bottom. The word 'writes' will not necessarily be what appears on each summary; if we edit the summary significantly then some other phrase would be more appropriate.

    However, what I would like to see is that we give this a try and then collect the views of the community after a while to decide. We have noted your suggestion - and I expect that there will be others in the coming days and weeks - and once we have something of a consensus we will revisit this to identify the optimum solution. We would rather not have the devs trying to respond to each suggestion as it occurs; that would be a very inefficient use of their time and effort.

      If there's a notable edit, how about "so-and-so tells us..."?

      I browse at -1 when I have mod points. It's unsettling.

        We have a variety of phrases that we can use - that isn't a particular problem for us. However, after the discussion a few days ago, explaining why the edit was necessary might take more space. Having it at the bottom makes it easier to implement a interim quick-fix solution while we decide what exactly is needed and how it can be best implemented.
