Comment 38 for bug 1469179

We are having the same problem, we use cinder iscsi volumes as storage backend.

The placement API gives the following error when we create a volume bigger then the local disk of the nova compute node:

Got no allocation candidates from the Placement API. This may be a temporary occurrence as compute nodes start up and begin reporting inventory to the Placement service. (nova-16.0.7/lib/python2.7/site-packages/nova/scheduler/manager.py:133)
