Thanks for following up. Do you happen to know how far it would get on runs where it went on to hang? Would it be it in the middle of a job or was it still doing setup or varied? Would it take hours to happen? On 7 March 2018 at 15:39, Rob Scheepens <rob.scheepens@xxxxxxxxxxx> wrote: > Adding to David's comments: my success percentage was roughly 30%.

I can see your desire for a simplified reproducer. When I get back to this issue, I will see what I can come up with. I am sure something simpler will reproduce the issue, but I have not spent the time to find something simpler that works. I will explore number of disks/files, numjobs and also determine if the working set makes any difference. > > In my experience, the python script never completed when run on Windows. Rob had better luck than I did and the script ran to completion for him several times, but it also showed the failure multiple times as well, but I don't remember what the pass percentage was for him. > > When I run the same python or bash script on Linux (just updating the path to the raw disks and the ioengine), it runs 100% reliably. -- 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
