If I recall correctly, it's due to overlaps of the ios screwing up the verify headers. It's not impossible to fix, but you have to either relax the IO coverage or make the random block generator more clever (so eg once a 512b block has been allocated, you can only fit < 128KB blocks into the remaining offsets). -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
