Can two single-node hosts be used together?

两个单节点主机可以组合使用吗？
我看文档【多机多盘】最少需要4台服务器。但是我看横向扩容添加集群的方式是将另一个集群池添加进来。那么一个单机的集群池可以加进来吗？

Can two single-node hosts be used together?
I read in the document [Multiple machines and multiple disks] that at least 4 servers are required. But I see that the way to add a cluster for horizontal expansion is to add another cluster pool. So can a single-machine cluster pool be added?

Yes, it is not possible to join with 1 server.

They must have the same stripe.
