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.

    Anyone running raid 0 does so knowing that their data exists in a fragile bubble.

    Precisely.

    This is why I take frequent backups of my RAID 0.
