Yeah, your CRUSH rule says to separate replicas across hosts. You have
only one host.
You can add another host and the PGs will go clean. Or, you can change
your CRUSH rule to separate across osds (not hosts) with
ceph osd crush rule create-simple myrule default osd
This should get crush ruleset 3; to confirm,
ceph osd crush dump
Then set your pools to use it with
ceph osd pool set data crush_ruleset 3
ceph osd pool set metadata crush_ruleset 3
ceph osd pool set rbd crush_ruleset 3
Just remember to switch back to replicating across hosts when your cluster
grows!
