Openstack — не удалось создать экземпляр с использованием параметра зоны доступности

Краткое содержание

У меня довольно небольшой кластер Openstack с 2 AZ: AZ-GOLD-6248R имеет 3 вычислительных узла, а AZ-E5-2630 имеет 1 вычислительный узел (оба AZ имели разные характеристики).

  1. Я могу создать экземпляр AZ-E5-2630 с помощью Horizon или интерфейса командной строки openstack.
  2. Я не могу создать экземпляр AZ-GOLD-6248R с помощью Horizon или интерфейса командной строки openstack с параметром --availability-zone, ошибка.No Valid Host was Found
  3. Но я могу создать экземпляр AZ-GOLD-6248R, используя параметр --host в CLI openstack.
  4. Это происходит во всех проектах и ​​учетных записях пользователей.
  5. Все гипервизоры работают и имеют много доступных ресурсов.

Моя спецификация кластера

  • 3 узла контроллера, 1 вычислительный узел на AZ-GOLD-6248R, 3 вычислительных узла на AZ-E5-2630
  • Внутреннее хранилище для виртуальной машины, тома и образа (cinder, glight) с использованием хранилища NFS в другом кластере.
  • Развертывание Openstack с использованием Kolla Ansible, версия openstack. Йога
  • ОС Ubuntu 22.04 ЛТС

Что я сделал

  1. Перезапустите службы Neutron и OVN на контроллере (neutron_server Neutron_ovn_metadata_agent openvswitch_db ovn_northd ovn_nb_db ovn_sb_db ovn_controller)
  2. Перезапустите службы Nova на контроллере (nova_conductor nova_scheduler)
  3. Перезапустите службы Neutron и OVN на вычислительных узлах (openvswitch_db ovn_controller Neutron_ovn_metadata_agent)
  4. Перезапустите службы Nova на вычислительных узлах (nova_compute nova_api).
  5. Перезапустите службу Placement API на контроллере (placement_api).
