Public bug reported:

Description
===========

When trying to launch an instance and nova determines that a compute
node is out of disk space, other hypervisors are not considered for
scheduling.

Steps to reproduce
==================

OpenStack deployed using local storage on two nodes (using Kolla), 50 GB disk in my lab.
Launch instances until disk is near full, fex 2 Centos with flavor with 20 GB disk.
Launch another instance with flavor 20 GB disk.

Expected Result
===============
Nova schedules the "other instance" on the second compute host where there are sufficient resources.

Actual Result
=============
Nova fails with "Not Enough Hosts"
