Run status group 0 (all jobs):
That's very weird, I wonder why fio exits. Can you try --debug=all instead and send that to me? Basically fallocate failing should not matter at all, the writes will extend the file. Perhaps sparse files don't work in AIX on your file system? In that case, you probably want overwrite=1 to have fio lay out the file manually for you.
