Compile fio with RADOS and RBD ioengine

Posted on

Binary packages of Fio often don’t come with rado and rbd ioengine. In order to use such ioengine to test Ceph, you need to compile the fio on your own. Below are step by step instructions to build it.

  1. Clond source code
    clone the source code and check out to the specific version you want to compile. (I used fio-3.27)

    git clone git://git.kernel.dk/fio.git
    git checkout fio-3.27
  1. Install dependecy library and compile

    apt install -y librbd-dev
    rados=yes ./configure

    #you should be able to see in the log
    # Rados engine                  yes
    # Rados Block Device engine     yes

    rados=yes sudo make 
    rados=yes sudo make install
  1. Verify
    you should be able to see rados and rbd after installation,

    Available IO engines:
            cpuio
            mmap
            sync
            psync
            vsync
            pvsync
            pvsync2
            null
            net
            netsplice
            ftruncate
            filecreate
            filestat
            filedelete
            posixaio
            falloc
            e4defrag
            splice
            mtd
            sg
            io_uring
            libaio
            rados  <<<<<<<
            rbd    <<<<<<<

you now run rados ioengine to benchmark Ceph
