1.如何使用cinder帮助命令?
2.如何查看用户的所有资源?
3. cinder credentials命令的作用是什么?
cinder命令初学: 1、#cinder help 获得帮助信息,列出所有命令。 2、[root@wi115-10 ~]# cinder absolute-limits
+-------------------------+-------+
| Name | Value |
+-------------------------+-------+
| maxTotalVolumeGigabytes | 1000 |
| maxTotalVolumes | 10 |
+-------------------------+-------+ 列出当前用户的所有资源(Print a list of absolute limits for a user),此用户能够用的磁盘总大小为1000G,volume个数最大为10个。 3、[root@wi115-10 ~]# cinder create --display_name cin01 10
+---------------------+--------------------------------------+
| Property | Value |
+---------------------+--------------------------------------+
| attachments | [] |
| availability_zone | nova |
| created_at | 2012-12-18T07:03:08.490263 |
| display_description | None |
| display_name | cin01 |
| id | 93b42627-f4db-4e70-8531-5687b30cc32a |
| metadata | {} |
| size | 10 |
| snapshot_id | None |
| status | creating |
| volume_type | None |
+---------------------+--------------------------------------+ 创建一个volume,后还可以接其他参数,如:--volume_type <type_name>。 4、[root@wi115-10 ~]# cinder list
+--------------------------------------+-----------+--------------+------+-------------+-------------+
| ID | Status | Display Name | Size | Volume Type | Attached to |
+--------------------------------------+-----------+--------------+------+-------------+-------------+
| 65d23a41-b13f-4345-ab65-918a4b8a6fe6 | available | qt | 10 | None | |
| 93b42627-f4db-4e70-8531-5687b30cc32a | error | cin01 | 10 | None | |
+--------------------------------------+-----------+--------------+------+-------------+-------------+ 列出所有的volume(刚刚创建的那个error了T_T。。。。),与cinder没有独立出来之前的 # nova volume-list命令功能相同。 5、[root@wi115-10 ~]# cinder delete 93b42627-f4db-4e70-8531-5687b30cc32a [root@wi115-10 ~]# cinder list
+--------------------------------------+-----------+--------------+------+-------------+-------------+
| ID | Status | Display Name | Size | Volume Type | Attached to |
+--------------------------------------+-----------+--------------+------+-------------+-------------+
| 65d23a41-b13f-4345-ab65-918a4b8a6fe6 | available | qt | 10 | None | |
+--------------------------------------+-----------+--------------+------+-------------+-------------+ 删除一个volume,#cinder delete <volume_id or volume_name>,与cinder没有独立出来之前的 # nova volume-delete <volume_id or volume_name>命令功能相同。 6、[root@wi115-10 ~]# cinder credentials 帮助里的解释是:“Discover endpoints that get returned from the authenticate services.”,这条命令的具体用途我不是很清楚,但是看列出来的类容,是将openstack的几个独立模块的authority信息给列出来了。

[root@wi115-10 ~]# cinder snapshot-list
[root@wi115-10 ~]# 删除一个volume快照。 12、[root@wi115-10 ~]# cinder type-create AP
+----+------+
| ID | Name |
+----+------+
| 1 | AP |
+----+------+ 创建一个volume类型,这样在创建volume的时候就可以加上类型: [root@wi115-10 ~]# cinder create --display_name ss --volume_type AP 2

| 1 | AP |
+----+------+ 列出所有的volume type。 14、[root@wi115-10 ~]# cinder type-delete 1
[root@wi115-10 ~]# cinder type-list
[root@wi115-10 ~]# 删除指定的volume type。不知道是什么原因,之前在测试创建有类型的volume时,--volume_type后只能接type的名字,而在删除type时,只能接type的ID。 另外,cinder还有几个关于quato的命令,目前没有研究有什么作用,待进一步学习。
