## 初始化流程:

###step 1
启动store、directory、proxy、pitchfork
store启动后,zookeeper看到/rack 有store节点

###step 2:
调用space()函数,初始化store,调用完成后,磁盘空间会被分配;bfs存储目录看到生成的volume文件。

###step 3:
调用groups()函数,store分组,调用完成后,zookeeper看到/group/ 有组节点

###step 4:
调用volumes()函数, 生效volume,调用完成后,zookeeper看到/volume/有volume节点

### Done
