openstack之cinder命令存储
翟修明
说明
cinder volumes的配置项，添加一个backend_host 目的是在cind volumes在不同控制节点上切换时，从直接点主机名称不一致，导致不能管理之前控制节点上时创建的cinder卷；该配置项就时统一这个控制节点的名称问题；
同理 fc的存储也需要用一个配置项 backend_host=fc:volumes;
iSCSi的存储也需要用一个配置项backend_host=iscsi:volumes
cinder命令初学：
1、cinder help
获得帮助信息，列出所有命令。
2、cinder absolute-limits
[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、cinder create --display_name cin01 10
[root@wi115-10 ~]# cinder create --display_name cin01 10
+---------------------+--------------------------------------+
| Property | Value |

| 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、cinder list
[root@wi115-10 ~]# cinder list

+--------------------------------------+-----------+--------------+------+-------------+-------------+
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、 cinder delete ID(cinder list 查看)
[root@wi115-10 ~]# cinder delete 93b42627-f4db-4e70-8531-5687b30cc32a

6、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。

14、 cinder type-delete 1
[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。
