in cinder-scheuduler.log: No weighed hosts found for volume with properties: {'extra_specs': {'multiattach': '<is> True'}}

In principle, you can create multi-attach volumes. It works for other Cinder backends; perhaps it doesn't for Ceph. In any case, in Mitaka Nova can't attach a volume to more than one instance, so that multi-attach is fairly useless.
