That works now:
$ fio --create_only=1 --name=test --directory=./tests --rw=read
--size=10M --bs=4k --numjobs=4
test: (g=0): rw=read, bs=4K-4K/4K-4K, ioengine=sync, iodepth=1
...
test: (g=0): rw=read, bs=4K-4K/4K-4K, ioengine=sync, iodepth=1
fio-2.0.7-13-g3b7f

Run status group 0 (all jobs):
$ ls tests/
test.1.0  test.2.0  test.3.0  test.4.0

Nice!
Thanks, Georg
