Hi Itamar,

hosted engine supports running on *multiple* nodes, providing out of the box HA between them. the setup should ask you if this is the second host and take care of all the right things to copy.
thanks for the pointer. The documentation at [1] describes the required steps to setup a second node. Unfortunately it failed for me because my second node was added to the cluster before [2].
Indeed. Might it be possible to not just move to maintenance but remove it from the engine? Then you can try again deploy as a second host.
Even manual setting the second node to "maintenance" and back to state "up" didn't help, hosted-engine-setup as unable to detect the host's state [3].
This is obviously a bug, as Itamar suggested, but I do not think it will be solved for 3.4, except for perhaps a cleaner error message.
Though following the steps was enough to start the hosted-engine VM manually on the second node. This makes a manual failover possible, which is sufficient for now :)
Well, this is also an unplanned, unsupported configuration. Might work for you - I don't know about anyone that tried that - but if possible, it's really better if you can add another host by hosted-engine --deploy.
Thanks - Frank
