It’s very easy:

  1. Why is Grafana down, and can it be brought back up?
  2. If it can’t be brought back up, first use tiup cluster scale-in <cluster_name> -N <grafana_node_ip:port> to scale in Grafana.
  3. Then use tiup cluster scale-out to scale out one Grafana instance.

The expansion YAML file you wrote has a problem.
grafana_servers:

  • host: xxxx
    port: 3000
    deploy_dir: /home/tidb-deploy/grafana-3000

Write it this way.

Pay attention to whether it is an indentation issue.

Try a single line.

Your current problem is with the format.
You can resolve it by expanding or shrinking.
However, the data might be lost. I have tested changing the directory before.
