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.
