Hi,
When I run fio with --create_only=1 and it runs out of space, it still
exits with status 0. I could not figure out if this was intentional
(except for the fill_device case, where this is obviously the expected
behavior).
$ cat ~/fio
[global]
ioengine=posixaio
rw=readwrite
size=2g
directory=${HOME}/mounts/testdisk
thread=1
[trivial-readwrite-1g]
$ df -h .

$ echo $?

A trivial patch for this gives me the behavior I expect.
