Then come up with something that allows you to have +AD4- sequential writes IO within a zone, and something that allows you to decide +AD4- how many zones to use, when to skip between zones, etc. Hello Jens, SMR support for fio has been reworked. The reworked patches are available at https://github.com/axboe/fio/pull/585. The following two test scripts allow to verify whether the fio behavior is identical for SMR and non-SMR storage media: +ACo- t/zbd/run-tests-against-regular-nullb +ACo- t/zbd/run-tests-against-zoned-nullb Thanks, Bart.
