创建云硬盘卷类型
创建type标识的卷类型。
可以通过cinder type-create命令来创建卷类型，创建了一个名为“lvm”的卷类型。
cinder type-create Ivm
+--------------------------------------+------+-------------+-----------+ | ID | Name | Description | Is_Public | +--------------------------------------+------+-------------+-----------+ | 4f9e9349-d925-418e-9a78-215c569c009b | Ivm | - | True | +--------------------------------------+------+-------------+-----------+
查看云硬盘类型
可以通过cinder type-list命令来查看现有的卷类型。
cinder type-list
+--------------------------------------+-------+-------------+-----------+ | ID | Name | Description | Is_Public | +--------------------------------------+-------+-------------+-----------+ | 4f9e9349-d925-418e-9a78-215c569c009b | Ivm | - | True | | 6253684c-de6b-4bd2-8cee-e81bea05a905 | type1 | - | True | +--------------------------------------+-------+-------------+-----------+
创建带标识云硬盘
下面以type标识为例，创建一块带“Ivm”标识的云硬盘，命令如下。
[root@controller ~]# cinder create --name type_demo --volume-type Ivm 1
+--------------------------------+--------------------------------------+
| Property | Value |

| user_id | 0befa70f767848e39df8224107b71858 |
| volume_type | Ivm |
创建成功后可以通过命令查看结果,可以看到该卷的volume_type字段已修改为“ Ivm",查询命令如下。
cinder show type_demo
