--------------------------------

 

volumev3가 없으면 아래와 같은 error가 나옴 그래서 volumev3도 생성 필요.

[root@network ~]# source ~/keystonerc
[root@network ~]# cinder service-list
ERROR: publicURL endpoint for volumev3 service not found
[root@network ~]#

 

------------------------------------------------

인스턴스가 삭제 안되거나 볼륨이 삭제안될때

컨트롤러host와 네트워크 host 에서.. 데몬 재시작

[root@controller ~]# systemctl restart openstack-cinder-api openstack-cinder-scheduler

[root@network ~]# systemctl restart openstack-cinder-volume

 

-----------------------------------------

볼륨삭제 안될때 강제 삭제

 

status가 available일때만 삭제 가능 하지만 deleting또는 creating에서 멈춰있을때 삭제가 안됨

[root@controller ~]# openstack volume list
+--------------------------------------+-----------+----------+------+-------------+
| ID                                   | Name      | Status   | Size | Attached to |
+--------------------------------------+-----------+----------+------+-------------+
| b1ad9f4e-2f49-4598-b538-0c1f68de90e5 | ceph-vol1 | deleting |    1 |             |
+--------------------------------------+-----------+----------+------+-------------+

 

그래서 DB에서 적용해서 삭제해야함.
