【产品名称】oceanbase社区版
【产品版本】ob-deploy-1.2.1 oceanbase-ce-3.1.2
【问题描述】obd扩容集群失败1-1-1扩容到2-2-2
三台服务器通过obd部署集群obce-3zones为1-1-1模式，通过obd扩容为2-2-2，服务器数量不变，采用不同的端口启动observer。
1、修改配置文件添加新的observer配置不同的目录及端口
[admin@obd soft]$ obd cluster deploy obce-3zones-2 -c obce-3zone-addserver.yaml
Update OceanBase-community-stable-el7 ok
Update OceanBase-development-kit-el7 ok
oceanbase-ce-3.1.2 already installed.

2、添加部署的ob到原有集群
修改/home/admin/.obd/cluster/obce-3zones
vi config.yaml
