Running Fio under AIX 7

Running Fio under AIX 7

[Georg Schönberger]

Hi fio users,

I am trying to run Fio under AIX 7 - according to the documentation there shouldn't be any problem with it.
For now I am getting the following error, do you have any idea what's the problem here (filesystem jfs/jfs2)?

Thanks for you help, Georg

Odd, so it's posix_fadvise() getting EINVAL. Most likely reason for that
is that fio is not picking up the right values for it.

It finds them here, on this platform:

AIX aixbuild 3 5 00C1DC964C00

Does it need some other magic on AIX 7 to find them? You can bypass the
error by setting invalidate_cache=0, but it would be great if you could
dig around a bit in /usr/include and see what is up. Alternatively, if I
can log into the machine, I can definitely fix it up.

Setting invalidate=0 did not fix the error. Or do I have to set it an other option?

# fio --rw=write --name=test --size=10M --invalidate=0
test: (g=0): rw=write, bs=4K-4K/4K-4K/4K-4K, ioengine=sync, iodepth=1
fio-2.1.2

test: Laying out IO file(s) (1 file(s) / 10MB)

fio: pid=0, err=22/file:filesetup.c:412, func=invalidate_cache, error=Invalid argument

What did you mean with digging around in /usr/include? I expect you mean to look at posix_fadvise, but what information do you exactly need?

Thanks a lot, Georg
