Describe the results you received:
docker@master1:~$ docker swarm leave
Error response from daemon: You are attempting to leave cluster on a node that is participating as a manager. The only way to restore a cluster that has lost consensus is to reinitialize it with `--force-new-cluster`. Use `--force` to ignore this message.
docker@master1:~$ docker swarm leave --force
Error response from daemon: context deadline exceeded
