Hi Jens,
There's a bug in cinder that causes, at least, to get size wrong from
cinder. If you search a little bit you will find it. I think it's still
not solved.

I am working with Cinder Multi Backends on an Icehouse installation and have
added another backend (Quobyte) to a previously running Cinder/Ceph
installation.
I can now create QuoByte volumes, but no longer any ceph volumes. The
cinder-scheduler log get’s an incorrect number for the free size of the volumes
pool and disregards the RBD backend as a viable storage system:
