Manually deactivating the maintenance mode on the source instance

For the final migration, the maintenance mode is activated on the source instance. This means that the instance can no longer be used via the graphical user interface. Normally, the maintenance mode is automatically deactivated if the final migration fails. If this is not the case, the maintenance mode can be deactivated manually on the source instance.

Requirement

  • Final migration has failed.
  • The source instance is in maintenance mode.
  • The source instance can still be reached via its FQDN.

CES VM procedure

  • Log in to the command line of the source instance, e.g. via SSH.
  • Switch to superuser mode (sudo su).
  • Delete the ETCD key /config/_global/maintenance with the command etcdctl rm /config/_global/maintenance.

CES MN procedure

  • Execute the following command:

    kubectl edit cm global-config
    • The global-config opens in a command line editor (e.g. Vim)
  • Remove the key maintenance with the corresponding key from the file
  • Save the changes. The change to the maintenance key is automatically recognized and applied by the other components.
