Ceph 풀 삭제 코드 백엔드로 OpenStack을 구성해 보았습니다.
다음 블로그처럼 —data-poolceph.conf에서 사용하려고 합니다.rbd default data poolhttps://themeanti.me/technology/2018/08/23/ceph_erasure_openstack.html, 하지만 이미지를 생성할 때 이와 같은 오류가 발생하면서 여전히 문제가 발생합니다.

Openstack은 복제본 풀(glance, cinder, nova)에서 만든 키링을 사용하여 ceph에 연결합니다.

답변1
이 오류의 주요 문제는 키링이 데이터 풀에 액세스할 수 없다는 것입니다.
이전 키는 다음과 같습니다
ceph auth get-or-create client.glance mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=images -o /etc/ceph/ceph.client.glance.keyring
올바른 키는 다음과 같습니다
ceph auth get-or-create client.glance mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=images, allow rwx pool=images_data' -o /etc/ceph/ceph.client.glance.keyring
