[root@ceph-admin rbd0]# rbd help create | grep thick [root@ceph-admin rbd0]# Maybe not support on the Luminous.

Hi! Although I'm not sure why you'd want to do it, there's a thick provision option for RBD create, i.e. it is possible: $ rbd help create | grep thick --thick-provision fully allocate storage and zero image Note that fully allocating and zeroing the image means writing data to every block, which may take considerable time.
