You need to change the CRUSH map to select osd instead of host.

             this is what it shows.
             does it mean I need to add up to 3 osds? I just use  the
        default setup.


        If you went with the defaults then your pool size will be 3,
        meaning it
        needs 3 copies of the data (replica 3) to be valid - as you only
        have
        two nodes/osd's that can never happen :)

        Your options are:
        - Add another node and osd.
        or
        - reduce the size to 2.(ceph osd set <poolname> size 2)
