Запуск службы MAAS Region Controller и API

Question 1

После отключения питания наша установка OpenStack вышла из строя. Первый шаг - попытаться восстановить и запустить MAAS, но у меня проблемы с этим. RC и CC работают и могут общаться (есть сеть).

В моем понимании API контроллера MAAS Region Controller запускается как приложение Django через WSGI на Apache. Apache работает, но не удается загрузить сценарий MAAS WSGI ( /usr/share/maas/wsgi.py ). Следовательно, сервис и API никогда не запускаются. RabbitMQ и другие сервисы работают на RC. Я также пытался сделать:

dpkg-reconfigure maas-region-controller

без какого-либо успеха.

Журнал ниже можно найти в /var/log/apache/error.log .

Есть идеи, что я могу попробовать?
