"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/ -- 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
