Hi.
We're trying to run fio 2.1.7 on AIX 6 and we can't seem to eliminate these
errors:
fio: posix_fallocate fails: Invalid argument
This one you can ignore, or you can get rid of it by adding:
fallocate=none
to the job file.
fio: pid=0, err=22/file:filesetup.c:418, func=invalidate_cache, error=Invalid
argument
Fio should probably just ignore these flush-cache warnings and continue
on, it's not really a fatal condition. I have attached a patch for you,
can you apply that and give it a go?
we always get one or the other. It doesn't matter too much what command we run,
what options, etc. We saw a web page which indicates that fio requires an
Asynch IO package to be installed and running on AIX. Is that correct? We're

You'd get a different error if that was your issue.

Isn't that always the case with AIX? :-)
