[Encountered Problem: Phenomenon and Impact]
During the cluster’s data center migration, in the final step, after using tiup to expand with 3 new PDs, switching the leader, and scaling down the old PDs, the script of TiKV still contains the offline PD nodes in the --pd parameter:
–pd “,,,”
The ps -ef|grep tikv command shows that the PD list still contains the old offline PDs.
What should I do now?

It doesn’t matter, it will change when TiKV restarts someday.

However, the old PD is no longer in your TiUP cluster configuration file. When you reload the TiKV nodes or restart the cluster, this will be overwritten with the new one.

It will be gone after a restart.
