Hello, The code on the master branch of my fio repository on github has been updated again. The changes compared to the previous version are: +ACo- A new job option has been added, namely zonemode. zonemode+AD0-zbd has to be specified when filename refers to a zoned block device. zonesize has a new meaning for zonemode+AD0-zbd. When both zonemode and zonesize have been specified and filename refers to a regular block device the I/O pattern the same as for a zoned block device (at least if all write pointers of the zoned block device are reset before fio is started). This behavior change was requested by Jens. +ACo- A subtle bug has been fixed that caused I/O against a zoned block device to stop early if multiple jobs were doing random writes to the same LBA range and with the random map enabled. +ACo- The zonemode+AD0-zbd do+AF8-verify+AD0-1 combination no longer causes fio to report verify errors when run against the conventional zones of a zoned block device. +ACo- The code for skipping offline zones should now work. Offline zones were not skipped in previous versions. I have not yet tested this code - testing this change requires access to a real or simulated openchannel SSD. +ACo- Several new unit tests have been added to t/zbc/test-zbc-support. See also https://github.com/axboe/fio/pull/585. Best regards, Bart.
