show variables like "log_bin"; show pump status; show drainer status; |
总结：
1.先将pump的节点缩容到12.配置tidb的binlogEnabled: false配置tidb的binlogEnabled: false
2.将pump节点缩容到0
如果pump的pod无法自动删除，可以标记为下线

kubectl -n tidb exec -it tidb-cluster-drainer-0 bash
/binlogctl -pd-urls=http://tidb-cluster-pd:2379 -cmd update-pump -node-id tidb-cluster-pump-0:8250 --state offline

/binlogctl -pd-urls=http://tidb-cluster-pd:2379 -cmd update-pump -node-id tidb-cluster-pump-2:8250 --state offline |
3.删除pump配置项
4.删除 Pump StatefulSet 资源
