I could be wrong but doesn't an iodepth of 32 and 64 jobs means that you would try and queue up 2048 (32*64) 4K I/Os on the same disk at once? Does /dev/sde really have a queue depth that high (cat /sys/block/sde/queue/nr_requests will tell you the kernel side) and is that your intent? -- Sitsofe | http://sucs.org/~sits/ -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
