Thanks Martin, that actually helps a lot, because I was afraid of the implications.
So the error must really be elsewhere. I am having another look at the logs from the
HostedEngineLocal and it seems to complain that no Gluster members are up, not even the
initial one.
I also saw no entries in the Postgres gluster_servers table so I, killed the
HostedEngineLocal VM and am doing another setup run to see if I can find out what's
going wrong.
