Well «crazy things» ? Since 8 days, I had 5 servers (over ~200) with data corruption on ext4 partitions (over LVM, over Xen blockfront/blockback, over DRBD, over LVM). Specialy with partitions mounted with defaults,noatime,nodev,nosuid,noexec,data=ordered (MySQL InnoDB data).
I was thinking about a problem with DRBD, then I saw this news... so... I don't know. Is it really the only way to trigger that problem ?
