查看云硬盘的挂载情况
(my_new_env) [email protected]:~$ nova volume-list

查看云硬盘的qos：nova volume-show <volume-id>
(my_new_env) [email protected]:~$ nova volume-show c2a0f8dc-a1a4-4912-a0a4-990b3916e5a7

将volume-qos设置为不限制：nova update-qos <server-id> <volume-id>

修改云主机的qos与云硬盘的qos非常相似，通过一下命令即可完成：
修改云主机的qos
nova update-instance-qos 3f0bab10-0ad9-4e88-b937-f316dd7cbe4a read_iops=0 write_iops=0 read_bps=0 write_bps=0
