Hi,
Apologies if this is documented somewhere else but I couldn't find it
in the fio man page, example job files, or list archives.
I'm exploring fio as a testing tool and it seems very well suited for
my needs. I'm currently running experiments with N sequential writers
all writing at 200k. The jobs file is very simple:
[global]
size=10m
directory=.
[foo1]
rw=write
rate=200k
[foo2]
...
fio creates various foo* files as part of its test but they all seem
to contain the same content. I would have expected fio to generate
random data in each file to avoid potential optimizations like
deduplication. Am I missing the flag to generate random test
patterns or is this behavior intentional?
I'm currently using fio 1.57.
Thanks,
brian
