## 管理 Nebula Graph 集群的 Storage 节点

首先将 Storage 节点加入 Nebula Graph 集群。更多管理集群命令请参见 [管理逻辑机架（Zone）](../4.deployment-and-installation/5.zone.md)。

从 3.0.0 版本开始，在配置文件中添加的 Storage 节点无法直接读写，配置文件的作用仅仅是将 Storage 节点注册至 Meta 服务中。必须使用`ADD HOSTS`命令后，才能正常读写 Storage 节点。

```ngql
ADD HOSTS <ip>:<port> [,<ip>:<port> ...];
```

<!--
```ngql
ADD HOSTS <ip>:<port> [,<ip>:<port> ...] [INTO NEW ZONE "<new_zone_name>"];
```
