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.

    [Neil Brown's] fix is present in the latest Linux Git code and will be found in [the May 24] release of Linux 4.1-rc5. [phoronix.com]
    This fix should also be back-ported to the relevant stable, currently-supported kernel series too in short order.
