    2. start writing objects to the pool

    # rados -p poolname bench 1000 write --no-cleanup

    3. Bring down 2 osds from 2 different localities which    contains data chunk:(for this we need to figure out
    mapping) for ex: with k=4, m=2, l=3 mapping looks like
    chunk nr    01234567
    step 1      _cDD_cDD    (Here DD are data chunks )
    step 2      cDDD____
    step 3      ____cDDD

    from "step 1" in the above mapping we can see that
    data chunk is divided into 2 localities which is
    anlogous to 2 data center. so in our case for ex
    we have to bring down (3,7) OR (2,7) OR (2,6) OR (3,6)    .
