У меня есть свой кластер k8s. Я пытаюсь связать кластер с openstack / cinder.
Когда я создаю PVC, я вижу PV в k8s и том в Openstack.
Но когда я связываю модуль с PVC, у меня появляется сообщение k8s - Cinder «0 / x узлов доступно: у узла (ов) был конфликт схожести узла тома».
Мой тест yml:

Почему K8 успешно создали том Cinder, но не могут запланировать модуль?
