1.找到没有连接的卷，闲置的表现故障是删除这个卷之后显示删除成功，但是之后还是显示可用

[root@manage25 ~]# cinder list|grep ava
+--------------------------------------+------+-----------+------+----------------------------------------------------------+

2.在存储集群中找打这个卷

[root@manage25 ~]# rbd ls -p volumes |grep e591df3c-23fa-4e68-a5c9-4dd39ac88cc2
volume-e591df3c-23fa-4e68-a5c9-4dd39ac88cc2

3.查看卷的信息

[root@manage25 ~]# rbd info volume-e591df3c-23fa-4e68-a5c9-4dd39ac88cc2 -p volumes
rbd image 'volume-da605031-49d3-49c9-9b7d-968b100dcb87':
  size 54GiB in 13824 objects
  order 22 (4MiB objects)
  block_name_prefix: rbd_data.2be40e33483d1e
  format: 2
  features: layering, exclusive-lock, object-map, fast-diff, deep-flatten
  flags: 
  create_timestamp: Wed Feb 10 23:51:03 2021
  # 有一个快照
  parent: volumes/0ad7ae89-8b34-4db4-a873-7904c46ce17b@snap
  overlap: 50GiB

4.查看这个卷有没有客户端，如果有可以吧客户端断开之后再删除，比如rbd map

[root@manage25 ~]# rbd status volume-e591df3c-23fa-4e68-a5c9-4dd39ac88cc2 -p volumes
Watchers: none

5.查看快照信息，可以看出这个快照，并且是受保护状态，如果要删除，确定对集群不会产生影响，删除快照再删除块设备即可。

[root@manage25 ~]# rbd info volumes/0ad7ae89-8b34-4db4-a873-7904c46ce17b@snap
rbd image '0ad7ae89-8b34-4db4-a873-7904c46ce17b':
  size 50GiB in 6400 objects
  order 23 (8MiB objects)
  block_name_prefix: rbd_data.2b6dd7341ee655
  format: 2
  features: layering, exclusive-lock, object-map, fast-diff, deep-flatten
  flags: 
  create_timestamp: Wed Feb 10 23:18:07 2021
  protected: True

6.删除卷的信息

删除块设备：rbd rm volume-e591df3c-23fa-4e68-a5c9-4dd39ac88cc2 -p volumes
删除卷设备：openstack volume delete e591df3c-23fa-4e68-a5c9-4dd39ac88cc2
