Subject: help with many files and many directory layout
Date: Wed, 28 Feb 2024 20:15:03 +1000 [thread overview]
Message-ID: <CADRoA0D_2YzTt-HLSpGQ_c91MzfTGB_eAKYyHzwDCfuCAi92BA@mail.gmail.com> (raw)
Hello,
I am trying to create a file layout of 3.5GB, 122 directories and
8,500 files spread across the directory structure.
This is what i have and i can't figure out if this is something fio can do.
[thousand-files]
directory=/tmp/fiojob
filename_format=a/b/c/($jobnum%69)/$jobname.$jobnum.$filenum
ioengine=posixaio
nrfiles=72
size=3500M
bs=8K
rw=randread
iodepth=128
openfiles=1000
numjobs=1
group_reporting=1
runtime=600
When I run this it doesn't do the mod function and just creates the
string repr as the directory name. Is there any way to achieve the
file layout I need?
Many thanks,
Don
