It appears that there is a limitation of 64 maximum zones. I tried to use 200 zones (100 empty and 100 with 1%) and I got the following error: "fio: access percentage don't add up to 100 for zoned random distribution (got=32)". Would it be possible to extend the number of zones up to 256 (since 200 is the maximum that you'd be able to use since the percentage is the smallest chance usable)? Here's the string I was using: fio --name=rand_reads --ioengine=libaio --direct=1 --exitall --thread --filename=/dev/sde --runtime=30 --readwrite=randread --iodepth=1 --random_distribution=zoned_abs:0/1879048192:1/256m:0/44023414784:1/256m:0/2415919104:1/256m:0/4563402752:1/256m:0/2415919104:1/256m:0/116500987904:1/256m:0/18253611008:1/256m:0/107642617856:1/256m:0/82946555904:1/256m:0/34359738368:1/256m:0/53687091200:1/256m:0/98247376896:1/256m:0/74088185856:1/256m:0/28185722880:1/256m:0/28722593792:1/256m:0/2415919104:1/256m:0/27380416512:1/256m:0/116769423360:1/256m:0/27380416512:1/256m:0/24159191040:1/256m:0/3221225472:1/256m:0/33554432000:1/256m:0/63619203072:1/256m:0/13958643712:1/256m:0/37312528384:1/256m:0/8589934592:1/256m:0/53687091200:1/256m:0/36507222016:1/256m:0/48586817536:1/256m:0/3489660928:1/256m:0/86436216832:1/256m:0/70866960384:1/256m:0/163477192704:1/256m:0/96099893248:1/256m:0/17985175552:1/256m:0/22817013760:1/256m:0/30064771072:1/256m:0/15300820992:1/256m:0/61740154880:1/256m:0/16911433728:1/256m:0/64961380352:1/256m:0/21206401024:1/256m:0/30870077440:1/256m:0/49660559360:1/256m:0/47513075712:1/256m:0/6710886400:1/256m:0/5637144576:1/256m:0/1879048192:1/256m:0/71940702208:1/256m:0/34896609280:1/256m:0/25232932864:1/256m:0/42949672960:1/256m:0/12079595520:1/256m:0/58787364864:1/256m:0/11005853696:1/256m:0/31943819264:1/256m:0/15837691904:1/256m:0/76772540416:1/256m:0/24427626496:1/256m:0/16642998272:1/256m:0/4831838208:1/256m:0/17179869184:1/256m:0/34628173824:1/256m:0/70330089472:1/256m:0/20937965568:1/256m:0/21474836480:1/256m:0/22548578304:1/256m:0/8321499136:1/256m:0/87509958656:1/256m:0/33017561088:1/256m:0/2952790016:1/256m:0/2415919104:1/256m:0/42949672960:1/256m:0/79725330432:1/256m:0/48586817536:1/256m:0/4563402752:1/256m:0/5905580032:1/256m:0/20669530112:1/256m:0/17179869184:1/256m:0/4563402752:1/256m:0/121064390656:1/256m:0/41875931136:1/256m:0/63082332160:1/256m:0/13958643712:1/256m:0/17985175552:1/256m:0/46707769344:1/256m:0/1342177280:1/256m:0/23085449216:1/256m:0/38654705664:1/256m:0/47244640256:1/256m:0/5100273664:1/256m:0/77846282240:1/256m:0/17179869184:1/256m:0/18522046464:1/256m:0/40533753856:1/256m:0/83483426816:1/256m:0/1342177280:1/256m:0/61471719424:1/256m:0/61740154880:1/256m:0/100126425088:1/256m --output-format=terse Thanks, Phillip Chen On Thu, Nov 30, 2017 at 2:22 PM, Jens Axboe <axboe@xxxxxxxxx> wrote: > On 11/30/2017 02:19 PM, Phillip Chen wrote: >> It looks like it's working great!
