1：在cinder中裸磁盘通常为卷，所以就是对于卷的管理，创建，删除，更改之类的操作

一：volume管理

cinder来操作

1：创建卷

格式：

cinder create --name volume1 --description  "new volume"  --volume-type size  c

创建了一个大小为2G的卷

[root@controller /]# cinder create --name volume1 --availabilitye nova 2

 

2：卷更新

1：重命名

格式：

cinder rename 旧卷名 新卷名

将volume1更改为test1

[root@controller /]# cinder rename volume1 test1
查看卷
[root@controller /]# cinder list
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
| ID                                   | Status    | Name  | Size | Volume Type | Bootable | Attached to |
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
| 656460cf-1d1d-4fbb-81e1-d34e065ab340 | available | test1 | 2    | __DEFAULT__ | false    |             |
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
[root@controller /]#

2：修改状态

可修改的状态有以下几种

available,error,createing,deleting，in-use，attaching，detaching ，error_deleting，maintenance

附加的状态：atached，detached，默认状态为none

格式：

cinder reset-state --state  状态 卷名

 

将test1的状态改为deleting的状态

[root@controller /]# cinder reset-state --state deleting test1
[root@controller /]# cinder list
+--------------------------------------+----------+-------+------+-------------+----------+-------------+
| ID                                   | Status   | Name  | Size | Volume Type | Bootable | Attached to |
+--------------------------------------+----------+-------+------+-------------+----------+-------------+
| 656460cf-1d1d-4fbb-81e1-d34e065ab340 | deleting | test1 | 2    | __DEFAULT__ | false    |             |
+--------------------------------------+----------+-------+------+-------------+----------+-------------+
[root@controller /]#

 

3：修改类型

修改类型之前这个卷的状态必须是available状态才能修改卷的类型

先将之前的test1的状态修改成可用的

[root@controller /]# cinder reset-state --state available test1
[root@controller /]# cinder list
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
| ID                                   | Status    | Name  | Size | Volume Type | Bootable | Attached to |
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
| 656460cf-1d1d-4fbb-81e1-d34e065ab340 | available | test1 | 2    | __DEFAULT__ | false    |             |
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
[root@controller /]#

 

成功将状态修改成available的状态

格式：

cinder retype 卷名 卷的类型

 

将test1的卷类型修改成lvm类型

[root@controller /]# cinder list
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
| ID                                   | Status    | Name  | Size | Volume Type | Bootable | Attached to |
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
| 656460cf-1d1d-4fbb-81e1-d34e065ab340 | available | test1 | 2    | __DEFAULT__ | false    |             |
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
[root@controller /]# cinder type-list
+--------------------------------------+-------------+---------------------+-----------+
| ID                                   | Name        | Description         | Is_Public |
+--------------------------------------+-------------+---------------------+-----------+
| 28550d3d-30cd-4c52-8d1a-c135ec2eee7f | __DEFAULT__ | Default Volume Type | True      |
| 6d590030-c967-4590-ac5f-9fc0cb72e7e4 | lvm         | -                   | True      |
+--------------------------------------+-------------+---------------------+-----------+
[root@controller /]# cinder retype test1 6d590030-c967-4590-ac5f-9fc0cb72e7e4 
[root@controller /]# cinder list
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
| ID                                   | Status    | Name  | Size | Volume Type | Bootable | Attached to |
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
| 656460cf-1d1d-4fbb-81e1-d34e065ab340 | available | test1 | 2    | lvm         | false    |             |
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
[root@controller /]#

　　

4：扩容的操作

可以从小改到大，但是不能从大改成小

格式：

cinder extend 卷名  size

 

将test1的空间增加到5

[root@controller /]# cinder extend test1 5
[root@controller /]# cinder list
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
| ID                                   | Status    | Name  | Size | Volume Type | Bootable | Attached to |
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
| 656460cf-1d1d-4fbb-81e1-d34e065ab340 | available | test1 | 5    | lvm         | false    |             |
+--------------------------------------+-----------+-------+------+-------------+----------+-------------+
[root@controller /]#

　　

　　

5：迁移

就是移动到特定的主机上面

 

二：type类型的管理

类型管理的语句

type-create 类型的创建
type-default 类型默认
type-delete 类型删除
type-key 
type-list 类型列表的查看
type-show 类型详情的查看
type-update 类型的更新

 

1：查看类型和创建类型

查看类型
[root@controller /]# cinder type-list
+--------------------------------------+-------------+---------------------+-----------+
| ID                                   | Name        | Description         | Is_Public |
+--------------------------------------+-------------+---------------------+-----------+
| 28550d3d-30cd-4c52-8d1a-c135ec2eee7f | __DEFAULT__ | Default Volume Type | True      |
| 46067585-3e65-4802-927b-b3cd80aaa6ce | none        | -                   | True      |
| 6d590030-c967-4590-ac5f-9fc0cb72e7e4 | lvm         | -                   | True      |
+--------------------------------------+-------------+---------------------+-----------+
[root@controller /]# 

创建类型

| 6d590030-c967-4590-ac5f-9fc0cb72e7e4 | lvm         | -                   | True      |
+--------------------------------------+-------------+---------------------+-----------+
[root@controller /]# cinder type-delete 46067585-3e65-4802-927b-b3cd80aaa6ce
Request to delete volume type 46067585-3e65-4802-927b-b3cd80aaa6ce has been accepted.
[root@controller /]# cinder type-list
+--------------------------------------+-------------+---------------------+-----------+
| ID                                   | Name        | Description         | Is_Public |

+--------------------------------------+-------------+---------------------+-----------+
[root@controller /]#

　　

3：修改类型

主要修改卷类型的名字，卷的描述，这个类型是否公共的

格式：

cinder type-update 类型 --name --description

 

将lvm这个类型名字改为none这个名字

[root@controller /]# cinder type-update 6d590030-c967-4590-ac5f-9fc0cb72e7e4  --name none
+--------------------------------------+------+-------------+-----------+
