We have an error here as the rule cannot be created until the buckets in the CRUSH map are not properly defined. So, before injecting the CRUSH map with the new stretch_rule, you have to create DC1 and DC2 buckets:

ceph osd crush add-bucket allDC root
ceph osd crush add-bucket DC1 datacenter
ceph osd crush add-bucket DC2 datacenter
ceph osd crush move DC1 root=allDC
ceph osd crush move DC2 root=allDC

Finally, you have to move your host  under the proper bucket in the CRUSH map:

ceph osd crush move ceph1 datacenter=DC1

Once everything is ready, you can inject the CRUSH map in the cluster with the new stretch_rule.

Thanks. Regards
