Title:
Nova compute service exception that performs cold migration virtual
machine stuck in resize state.
Status in OpenStack Compute (nova):
Fix Released
Status in OpenStack Compute (nova) train series:
Fix Released
Bug description:
Description:
In the case of a nova-compute service exception, such as down, the instance gets stuck in the resize state during cold migration and cannot perform evacuation.The command request for nova API is also issued, server_status and Task State have been changed, but compute cannot receive the request, resulting in the server State remaining in the resize State. When nova-compute is restarted, the server State becomes ERROR.It is recommended to add validation to prevent instances from entering inoperable states.
This can also happen with commands such as stop/rebuild/reboot.
Environment:
1. openstack-Q;nova -version:9.1.1
2. hypervisor: Libvirt + KVM
3. One control node, two compute nodes.
