Ah yes, good point, I always seem to assume that people are running fio out of the git repo. But yes, the IOPS is a recent(ish) addition. Though 2.0.3 is more than a year old at this point. > As Jens said, you can also switch to JSON format instead. > So maybe you are stuck to use Fio from the git repo to have a newer version. Yep, json is an even newer addition than terse v3, so an update is in order in any case. -- Jens Axboe -- 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
