Since there is no bare disk, the directory is directly specified as osd. It seems that specifying directory as osd is not supported in the new version of luminous,ceph-deploy.

# mkdir-p / data/ceph/data# chown ceph:ceph / data/ceph/data/# ceph-deploy osd prepare k8s2:/data/ceph/data # ceph-deploy osd activate k8s2:/data/ceph/data

Three nodes one osd for each node
