from the patch-immediately dept.

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.

    How does any of that apply when the system in question refuses to boot because of a failure of systemd?

        §1 Systemd is flawless and the solution to everything(tm)

        §2 If rule (1) should for any reason be wrong. Just ask Poettering about it's validity.

    It doesn't apply if the init system fails to initialize the system. How often does that happen, though? We run plenty of CentOS 7 and I don't remember having any failures to boot.

      I had it happen to me numerous times while running Debian systems that used systemd. I finally got fed up, and moved these Debian systems to other OSes.
