hello FIO experts,
I am a beginner in FIO, and I met with a problem.
Currently in my Ubuntu based server the "/dev/vdb1" volume is attached
to the "/home/batman/fio/cindervolume" path. FIO job is configured
like this
[global]
filename=fio-172_20_2_13
directory=/home/batman/fio/cindervolume rw=rw
rwmixread=60
rwmixwrite=40
bs=4k
rate=500k
direct=1
numjobs=1
time_based=1
runtime=14d
verify=crc32c
continue_on_error=all
group_reporting=1
[file1]
iodepth=1
; -- end job file --
FIO is started like this and works well:
/usr/bin/fio --size=10G
--output=/home/batman/fio/cindervolume/fio-172_20_2_13-process.log
/home/batman/fioApp/fio-seq-RW.job &
FIO version I use: fio-3.25
My next step would be to attach a 2nd volume for example "/dev/vdc" to
"/home/batman/fio/cindervolume-2" path, and I would do performance
measurement between the volumes. I was checking the FIO user’s guide,
https://fio.readthedocs.io/en/latest/fio_doc.html but unfortunately I
cannot figure out which parameter might help me to solve this topic.
By-the-way is this possible to do with FIO? If so, could you please
help me by giving some direction/hints?
thanks for your help,
/Robi
