Public bug reported:

In Juno-Release I am experiancing rbd_store_chunk_size setting the image
object size to bytes rather than kB resulting in much much more objects
being created

Icehouse Install
root@node-1:~# rbd info images/62e06da9-2d39-4c7f-a2d8-d869953b9996@snap
rbd image '62e06da9-2d39-4c7f-a2d8-d869953b9996':
        size 4096 MB in 512 objects
        order 23 (8192 kB objects)
        block_name_prefix: rbd_data.6a282e18d096
        format: 2
        features: layering
        protected: True

Juno Install
root@hvm003 ~]# rbd info images/136dd921-f6a2-432f-b4d6-e9902f71baa6@snap
rbd image '136dd921-f6a2-432f-b4d6-e9902f71baa6':
        size 4096 MB in 524288 objects
        order 13 (8192 bytes objects)
        block_name_prefix: rbd_data.10d73ac85fb6
        format: 2
        features: layering
        protected: True

Either the documentation needs updating or rbd_store_chunk_size needs to
be changed to set the object size in kB. Currently the workaround to get
back to 8MB object size is 'rbd_store_chunk_size = 8192'
