Subject: FIO performance measurement between volumes
Date: Thu, 13 Jan 2022 12:47:11 +0100	[thread overview]
Message-ID: <> (raw)

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

    directory=/home/batman/fio/cindervolume rw=rw

    ; -- end job file --

FIO is started like this and works well:
    /usr/bin/fio --size=10G
/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, 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,
