Looking at the logs, there are warning messages about inconsistent cluster id. After restarting, the local cluster id is local-member-cluster-id=fd16c20d10f48177, while the one read from tikv is remote-peer-cluster-id=18b4a84de13b98e3.

Do the other PD nodes have similar logs?

Is there an error on the TiKV side saying it can’t start?

The other PD nodes are normal, and TiKV is also normal.

The PD node returned to normal after reloading through scaling.
