Hi, How is LFSR used? When running the job file: [global] readwrite=randwrite size=64k bs=8192 random_generator=lfsr [test_job] fio returns: "fio: failed allocating random map. If running a large number of jobs, try the 'norandommap' option or set 'softrandommap'. Or give a larger --alloc-size to fio." I tried the recommendations in the message above to no avail. I also tried other combinations of size, bs, and readwrite. Thank you, Juan -- 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
