Subject: RE: Specify range and distribution of accesses
Thanks for the suggestions and patches. Using the latest fio
version, the JESD219 workload is possible:
# fio -version
fio-2.6-27-gd283
# fio --name=JESD219 --ioengine=libaio --direct=1 --rw=randrw --
norandommap --randrepeat=0 --rwmixread=40 --rwmixwrite=60 --
iodepth=256 --size=100% --numjobs=4 --
bssplit=512/4:1024/1:1536/1:2048/1:2560/1:3072/1:3584/1:4k/67:8k/10:1
6k/7:32k/3:64k/3 --random_distribution=zoned:50/5:30/15:20/80 --
overwrite=1 --filename=/dev/nvme0n1 --group_reporting --runtime=5m --
time_based --output=JESD219
That would fit well in the examples/ directory.
Agree, I have added it. I removed the 'overwrite=1' as that only applies
to files, not devices. And norandommap is redundant with a non uniform
random distribution, but it serves as documentation, so I left it.
size=100% was also removed, as that is the default.
