It was ok with or without the colon, the size didn’t seem to make a difference, but blocksize did.. see the commented block sizes below. fio2.fio [global] ioengine=windowsaio ;blocksize=64k - error ;blocksize=32k - error ;blocksize=16k - no error blocksize=16k direct=1 thread size=512g time_based runtime=10 [asdf] filename=F\:\\testfile:G\:\\testfile:H\:\\testfile:I\:\\testfile:J\:\\testfile:K\:\\testfile:L\:\\testfile:M\:\\testfile:P\:\\testfile Results: Run status group 0 (all jobs): READ: bw=141MiB/s (148MB/s), 141MiB/s-141MiB/s (148MB/s-148MB/s), io=1413MiB (1481MB), run=10001-10001msec -Dave -----Original Message----- From: Sitsofe Wheeler [mailto:sitsofe@xxxxxxxxx] Sent: Tuesday, October 31, 2017 2:28 PM To: David Hare <david.hare@xxxxxxxxxxxxxxx> Cc: Jens Axboe <axboe@xxxxxxxxx>; fio@xxxxxxxxxxxxxxx Subject: Re: FIO windows Hi, On 31 October 2017 at 20:46, David Hare <david.hare@xxxxxxxxxxxxxxx> wrote: > > If I remove - "blocksize=64k" "direct=1" "thread=8" "size=1g" > "time_based with runtime=10" or ":P\:\\testfile:" (the 9th drive) the file works. > > The below file generates this error: > fio: pid=8404, err=22/file:ioengines.c:333, func=td_io_queue, > error=Invalid argument > asdf: (groupid=0, jobs=1): err=22 (file:ioengines.c:333, > func=td_io_queue, error=Invalid argument): pid=8404: Tue Oct 31 > > > [global] > > ioengine=windowsaio > blocksize=64k > direct=1 > > thread=8 > size=1g > > time_based > runtime=10 > > [asdf] > filename=F\:\\testfile:G\:\\testfile:H\:\\testfile:I\:\\testfile:J\:\\testfile:K\:\\testfile:L\:\\testfile:M\:\\testfile:P\:\\testfile: "thread=8" should be the same as using "thread" and would be required on Windows. "P\:\\testfile:" should be "P\:\\testfile" (note the lack of trailing colon - see the examples in http://fio.readthedocs.io/en/latest/fio_doc.html#cmdoption-arg-filename ). time_based and runtime sound required. Perhaps a smaller blocksize means it takes longer than 10 seconds to hit the problem - presumably blocksize=128k is still as problematic? I'm also assuming the problem still happens with size=512m ? -- Sitsofe | http://sucs.org/~sits/ ��.n��������+%������w��{.n�������^n�r������&��z�ޗ�zf���h���~����������_��+v���)ߣ�
