root-filesystem borkage

Hm. After a reset, both 9TB-Filesystems were normal (journal replayed. But a
few minutes after the boot, we got really strange errors (see attachment) and
could only resurrect the root-filesystem with a live-cd and it's fsck, as grub
wouldn't detect a filesystem anymore. fsck fixed it, though (broken superblock
and some minor fixes). The system boots as I write this, and I'll continue the
same backup-tests but this time without barriers on both filesystems.
