I doubt that this is actually an ext3 problem so I'm taking a bit of a liberty, but... We have several machines that have two ext3 partitions (/, /boot) and a large raw partition. Something happened that destroyed both the ext3 partitions on all machines. I appears that the app writing to the raw partition had a bug that caused it to write to negative block numbers and that this wrote all over the disk. But I would have thought that the writes would have been constrained but the raw device. Is there an ext3 issue or is it a bug in the rawdevice implementation?
