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
+--------------------------------------+------+-----------+------+----------------------------------------------------------+
| ID | Name | Status | Size | Attached to |
+--------------------------------------+------+-----------+------+----------------------------------------------------------+
| 19067f72-9340-4e40-9277-dada28b50afe | | in-use | 500 | Attached to idc-bj-ops-paas.monitor-3 on /dev/vda |
| 84772cdf-6b5b-4e28-b1a5-4dd9b3999c9d | | in-use | 500 | Attached to idc-bj-ops-paas.monitor-1 on /dev/vda |
| 54176c63-128c-4d8f-80b6-dfa9d0b82ecd | | in-use | 500 | Attached to idc-bj-ops-paas.monitor-2 on /dev/vda |
| e591df3c-23fa-4e68-a5c9-4dd39ac88cc2 | | available | 500 | | 43 | - | true | |
2.在存储集群中找打这个卷
[root@manage25 ~]# rbd ls -p volumes |grep e591df3c-23fa-4e68-a5c9-4dd39ac88cc2volume-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
