Hi, It sounds quite unclear for me about the possibility *in Folsom* to have two distinct Cinder hosts having each one LVM backend called cinder-volumes ? As per the doc [1], I would say the answer is no, but could you please confirm ? If so, do you have any idea on how to trick a nearly full LVM cinder-volumes VG ? (I can't hardly add a new disk for adding a second PV). Thanks, -Sylvain [1] : http://docs.openstack.org/grizzly/openstack-block-storage/admin/content/multi_backend.html
