环境介绍
看官方文档 ， 什么环境也描述得不清楚，只说要在controller node 和share node 上做配置，也没有画一个架构图。
如果你有share node(上面有sdb, sdc等存储设备可用）的话，就按照文档来。
其实，更常见的一种情景时：
三个控制节点+N个计算节点， 其中控制节点上跑Manila服务， 由另外的一套存储（如Isilon, netapp等）提供NFS资源给Manila使用。
Manila 对接存储设备，其实类似cinder， 其backend driver因设备不同而不同； 但manila有一个通用的driver可以使用，叫generic , generic其实是拿Openstack环境中的cinder volume通过manila提供NFS服务。
下文以generic为例，详细描述配置，网络，以及使用Manila share的方法。
manila.conf配置
如下是我摸索出来的配置， service_instance_XXX是用service_image_name启动的instance时的一些参数，应该很好理解。
其中service_network_cidr 怎么配呢？
[generic]
share_driver = manila.share.drivers.generic.GenericShareDriver
interface_driver = manila.network.linux.interface.OVSInterfaceDriver
driver_handles_share_servers = True
service_instance_password = manila
service_instance_user = manila
service_image_name = manila-service-image
manila_service_keypair_name = default
cinder_volume_type = netapp-iscsi
service_instance_flavor_id = 22
service_network_name = manila-service-network
service_network_cidr = 10.56.60.0/24
service_instance_security_group = default
service_instance_name_template = manila_service_instance_%s
share_backend_name = GENERIC
volume_snapshot_name_template = manila-snapshot-%s
service_instance_smb_config_path = $share_mount_path/smb.conf
share_volume_fstype = ext4
share_helpers = CIFS=manila.share.drivers.helpers.CIFSHelperIPAccess, NFS=manila.share.drivers.helpers.NFSHelper
网络
manila服务启动之后,就会出现manila-service-network 网络，这个是service network, manila service instance运行在该网络中,在该instance中提供nfs server ， 这个instance在官方文档中也叫做share server,感觉叫法很混乱，所以文档不好懂。
[root@cloud-02 manila]# openstack network list

这个manila-service-network网络如何设置呢？我这里采用一个私网，建议不要跟系统中现有的网络相同，以便区分。
创建share network，所谓share network, 就是nfs client端。

service network 和 share network 如何通信呢？ service network是在service这个租户之下，而share network 是在其他的租户下面，
- 如果share network是一个租户的私有网络， 则manila要求该网络必须通过router连接到外部网络。
- 如果share network是一个公共的网络， 则由用户去保证share network和service network的互通，还没有测试！！！

图中的英文术语跟官方文档是一致的。

Manila Type
[root@cloud-02 manila-share]# manila type-create generic yes
yes代表的是driver_handles_share_servers=yes, 我的理解是manila driver是否要创建service instance，Manila backend driver必须明确指定这个参数
参见官方解释
For simplicity, this guide describes configuring the Shared File Systems service to use one of either:
the generic back end with the driver_handles_share_servers mode (DHSS) enabled that uses the Compute service (nova), Image service (glance), Networking service (neutron) and Block storage service (cinder); or,
the LVM back end with driver_handles_share_servers mode (DHSS) disabled.
在对接EMC isilon设备时，通常Openstack环境与存储设备是三层互通，2层不通。
所以这时，就需要设置driver_handles_share_servers 为false.
[root@cloud-sz-control-b13-02 neutron-openvswitch-agent]# manila create --share-type isilon nfs 3
ERROR: Share network must be set when the driver_handles_share_servers is true.

How to use the Nfs?
创建一个vm , 注意，它运行在share network里面。

Usual Case
share network 没有上接router
Manila使用geniric driver时， 要求share network的上面必须接到一个router中，为了和service network 打通，如果没有接，则会报如下错误：

## service instance 是如何提供nfs 的？
service instance 会挂载一个cinder volume上来，这个instance把/dev/vdb, vdc
```bash
[root@cloud-02 neutron-openvswitch-agent]# openstack volume list --all
