原来是用tidb-ansible安装的集群，切换到tiup后，用tiup新增tiflash节点，报错，但新节点上的tiflash已起来，监控上也能看到新节点，请问下是什么原因。报错信息：
- [ Serial ] - Download: component=alertmanager, version=v0.17.0, os=linux, arch=amd64
- [ Serial ] - Download: component=prometheus, version=v4.0.0, os=linux, arch=amd64

3.扩容文件
tiflash_servers:
- host: 192.168.1.4
4.扩容
tiup cluster scale-out aist-test-cluster scale-out.yaml
