The offline node usually indicates the TiKV node. You can determine whether the offline process is finished by the pd-ctl or the monitor. After the node is offline, perform the following steps:

  1. Manually stop the relevant services on the offline node.
  2. Delete the node_exporter data of the corresponding node from the Prometheus configuration file.
  3. Delete the data of the corresponding node from Ansible inventory.ini.
