创建卷

  1. 获取 demo 凭证，以非管理项目身份执行以下步骤

    $ . demo-openrc

  2. 创建一个 1 GB 卷

    $ openstack volume create --size 1 volume1

+---------------------+--------------------------------------+
| Field               | Value                                |
+---------------------+--------------------------------------+
| attachments         | []                                   |
| availability_zone   | nova                                 |
| bootable            | false                                |
| consistencygroup_id | None                                 |
| created_at          | 2016-03-08T14:30:48.391027           |
| description         | None                                 |
| encrypted           | False                                |
| id                  | a1e8be72-a395-4a6f-8e07-856a57c39524 |
| multiattach         | False                                |
| name                | volume1                              |
| properties          |                                      |
| replication_status  | disabled                             |
| size                | 1                                    |
| snapshot_id         | None                                 |
| source_volid        | None                                 |
| status              | creating                             |
| type                | None                                 |
| updated_at          | None                                 |
| user_id             | 684286a9079845359882afc3aa5011fb     |
+---------------------+--------------------------------------+

  3. 稍后，卷状态应从 creating 变为 available

    $ openstack volume list

+--------------------------------------+--------------+-----------+------+-------------+
| ID                                   | Display Name | Status    | Size | Attached to |
+--------------------------------------+--------------+-----------+------+-------------+
| a1e8be72-a395-4a6f-8e07-856a57c39524 | volume1      | available |    1 |             |
+--------------------------------------+--------------+-----------+------+-------------+

将卷附加到实例

  1. 将卷附加到实例

    $ openstack server add volume INSTANCE_NAME VOLUME_NAME

    将 INSTANCE_NAME 替换为实例的名称，将 VOLUME_NAME 替换为要附加到该实例的卷的名称。

    示例

    将 volume1 卷附加到 provider-instance 实例

    $ openstack server add volume provider-instance volume1

    注意

    此命令不会产生任何输出。

  2. 列出卷

    $ openstack volume list

+--------------------------------------+--------------+--------+------+--------------------------------------------+
| ID                                   | Display Name | Status | Size | Attached to                                |
+--------------------------------------+--------------+--------+------+--------------------------------------------+
| a1e8be72-a395-4a6f-8e07-856a57c39524 | volume1      | in-use |    1 | Attached to provider-instance on /dev/vdb  |
+--------------------------------------+--------------+--------+------+--------------------------------------------+

  3. 使用 SSH 访问您的实例，并使用 fdisk 命令验证卷是否存在，作为 /dev/vdb 块存储设备

     $ sudo fdisk -l

 Disk /dev/vda: 1073 MB, 1073741824 bytes
 255 heads, 63 sectors/track, 130 cylinders, total 2097152 sectors
 Units = sectors of 1 * 512 = 512 bytes
 Sector size (logical/physical): 512 bytes / 512 bytes
 I/O size (minimum/optimal): 512 bytes / 512 bytes
 Disk identifier: 0x00000000

    Device Boot      Start         End      Blocks   Id  System
/dev/vda1   *       16065     2088449     1036192+  83  Linux

 Disk /dev/vdb: 1073 MB, 1073741824 bytes
 16 heads, 63 sectors/track, 2080 cylinders, total 2097152 sectors
 Units = sectors of 1 * 512 = 512 bytes
 Sector size (logical/physical): 512 bytes / 512 bytes
 I/O size (minimum/optimal): 512 bytes / 512 bytes
 Disk identifier: 0x00000000

 Disk /dev/vdb doesn't contain a valid partition table

    注意

    您必须在设备上创建文件系统并挂载它才能使用该卷。
