** Changed in: nova Status: Incomplete => Expired -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1849154 Title: Live Migrations complete but occasionally fail to update the Openstack Database Status in OpenStack Compute (nova): Expired Bug description: [Description] Occasionally when evacuating vms off of nova compute hosts for host reboots, a vms migration will be reported as complete in the migration list, but queries to the openstack api, such as 'openstack show uuid' will report the host & hypervisor-hostname unchanged. The only indication that something is wrong is that power_state will be NOSTATE. We can see that the instance is in fact migrated and running on the new host with 'sudo virsh list --all | grep $instance_name'. In order to resolve this issue we perform a direct database edit such as: 'update instances set host="$newhost", node="$newhost.domain", progress="0" where uuid="" and deleted="0";' * In one instance, the 'progress' value was stuck at 99 and I needed to set that to 0 in the database as well. [Expected] Its expected that the live migration completes and that the instance in the openstack database correctly reflects the name of the new host, and its power state. [Impact] Instances that are found to be in power state NOSTATE are blocked from performing certain actions; instances in this state do not self recover. [Environment] Openstack Queens; Nova 17.0.10 libvirtd/virsh: 4.0.0 ceph: 12.2.8 neutron-openvswitch: 12.0.5 [Logs] In this particular set of logs (sosreports from the live migration source and destination hosts); the instance that was in error had uuid 67f328d0-cb5e-416a-9af4-c6e47e68a1e0.
