HI, You should do something like #ceph osd in osd.${num}: But If this is your tree, I do not see any osd available at this moment in your cluster, should be something similar to this xesample:
ID CLASS WEIGHT TYPE NAME STATUS REWEIGHT PRI-AFF -1 58.21509 root default -2 29.12000 host cephosd01 1 hdd 3.64000 osd.1 up 1.00000 1.00000 ...... -3 29.09509 host cephosd02 0 hdd 3.63689 osd.0 up 1.00000 1.00000 ......
