Bigger blocks that are still a multiple of 4Kbytes should work though... Further by default bsrange will only picks block sizes that are multiples of the minimum specified blocksize so bsrange=4k-64k should pick 4k, 8k, 16k, 32k, 64k (see http://fio.readthedocs.io/en/latest/fio_doc.html#cmdoption-arg-blocksize-range ). Is that clearer? -- Sitsofe | http://sucs.org/~sits/ -- 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
