Today, I installed a pump and a Drainer component. When checking the status, I found that there are actually two nodes, 10.13.2.141:8250 and 10.13.2.141:8249, which are no longer visible in the TiDB cluster. It is possible that the nodes were not properly removed before directly upgrading the cluster, and the metadata is still stored in PD. Now, I am unable to remove these two non-existent nodes using the binlog-ctl tool. I would like to ask how I should proceed.
