Не удается подключить том к экземпляру openstack

#openstack #openstack-nova #openstack-cinder

#openstack #openstack-nova #openstack-cinder

Вопрос:

Я пытаюсь прикрепить том к изображению. Мои попытки постоянно терпят неудачу.

Я использую следующую команду для создания вложения:

 openstack server add volume test_instance testvol
  

где test_instance — это мой экземпляр, а testvol — это том объемом 20 ГБ, который я создал с помощью Cinder.

Я не получаю сообщений об ошибках при попытке этого вложения, но когда я проверяю свой том, я не вижу вложения:

 cinder list

Я не вижу вложения. Вышесказанное — это то, что я получаю, независимо от того, пытаюсь ли я прикрепить testvol или volume1.

Просматривая журнал nova-compute, я получаю следующие сообщения:

Кто-нибудь знает, что является причиной этого сбоя? Как я могу подключить том к экземпляру?

Комментарии:

1. похоже, что проблема с библиотекой Python отсутствует или связана со старой версией…

2. Вы не предоставляете никакой информации об облаке (как оно было настроено) и работали ли когда-либо вложения тома. В любом случае, я бы попытался выяснить, что может вызвать ошибку «обнаружен сбой базы данных iSCSI». Возможно, несоответствие версии, как указано в предыдущем комментарии, или какая-либо ошибка конфигурации на вычислительном узле.
