Bug Description
Glance and Cinder appear to be using different defaults for the rbd_chunk_size while they should not or operations which involve snapshotting/
This is especially important when the Ceph cluster is at the Pacific level, where such a thing is enforced with the cluster returning error if it isn't, see https:/
While recent versions of Cinder are trying to workaround this by adopting whichever chunk size is in use for the source image, we should configure the services to use by the same value and eventually make it configurable for performance reasons.
puppet-glance and puppet-cinder support this already
