I've noticed that you used bs= and gave a range, that wont work. Fio
should fail to parse that, but alas, it does not and you get this:
file-8: (g=0): rw=randrw, bs=64-64/128K-128K/128K-128K, ioengine=psync, iodepth=1
which is 64b reads, 128K writes, 128K trims. I will look into why this
doesn't fail to parse, but in the mean time, you want to use
bsrange=64k-128k which will do what you intend it to.
