Fixed In Version:	openstack-nova-16.0.4-6.el7ost
Doc Type:	Bug Fix
Doc Text:	Prior to this update, a volume detach operation performed under certain failure scenarios could result in the removal of a volume's libvirt definition without full removal of the associated logical volume (LUN) from the host. This allowed Cinder to incorrectly perform subsequent operations while the compute host still had active paths to the device. As of this update, even under a failure scenario, Nova compute attempts to disconnect the LUN from the host. The result is a better release of the logical volume on the host.
