How to start _single_ OpenNebula Frontend node configured as HA setup

Is it possible to start a single oned node (part of a HA / RAFT cluster) in “single” mode? I ran into an issue configuring HA where there was no leader anymore, but only “follower” and “candidate”. In that state you are not allowed to make any changes to the cluster because there is no consensus yet (makes sense). At that point you have two options:

  1. create a third node to get consensus
  2. fall back to single node

I went for option 1. But I figured, in case of an emergency, I would like to be able to “rollback” to single node. Is this possible? What would I need to do to achieve that? I tried disabling oned.conf and restarting oned, but that did not help.
