The default crush rule uses "host" as the failure domain, so in order to deploy on one host you will need to make a crush rule that specifies "osd". Then simply adding more hosts with osds will result in automatic rebalancing. Once you have enough hosts to satisfy the crush rule ( 3 for replicated size = 3) you can change the pool(s) back to the default rule.
