| Doc Text: |
Previously, the Compute service only queried local disk statistics on Compute nodes, which are irrelevant when ephemeral disks are stored in RBD. This made it possible for the scheduler to prevent an instance from being scheduled when the total disk usage of instances already running on the node exceeded the total disk capacity as reported by the hypervisor driver. With this update, the Compute service now correctly queries Ceph for actual disk usage statistics.

*** Bug 1158201 has been marked as a duplicate of this bug. *** Can you please add steps about how to see these stats? *** Bug 1160408 has been marked as a duplicate of this bug. *** Look for the "disk_gb" column from `nova host-describe $hostname` and ensure it's appropriate for the rbd volume rather than the local disk. failed verification in version: python-nova-2014.1.3-8.el7ost.noarch python-novaclient-2.17.0-2.el7ost.noarch openstack-nova-common-2014.1.3-8.el7ost.noarch openstack-nova-compute-2014.1.3-8.el7ost.noarch verified in nova version: openstack-nova-cert-2014.1.3-9.el7ost.noarch openstack-nova-novncproxy-2014.1.3-9.el7ost.noarch python-nova-2014.1.3-9.el7ost.noarch openstack-nova-console-2014.1.3-9.el7ost.noarch openstack-nova-network-2014.1.3-9.el7ost.noarch openstack-nova-common-2014.1.3-9.el7ost.noarch openstack-nova-compute-2014.1.3-9.el7ost.noarch openstack-nova-conductor-2014.1.3-9.el7ost.noarch openstack-nova-scheduler-2014.1.3-9.el7ost.noarch openstack-nova-api-2014.1.3-9.el7ost.noarch python-novaclient-2.17.0-2.el7ost.noarch Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
