## Configuring the Secondary Zone in a Separate Cluster
-4. Edit the all.yml in group_vars
+5. Edit the all.yml in group_vars
```
copy_admin_key: true
**Note:** `rgw_zone_user`, `system_access_key`, and `system_secret_key` should match what you used in the Primary Cluster
-**Note:** `ansible_fqdn` domain name assigned to `rgw_multisite_endpoint_addr` must be resolvable from the Primary Ceph cluster's mon and rgw node(s)
+**Note:** `ansible_fqdn` domain name assigned to `rgw_multisite_endpoint_addr` must be resolvable from the Primary Ceph clusters mon and rgw node(s)
**Note:** if there is more than 1 RGW in the Secondary Cluster, `rgw_multisite_endpoints` needs to be set with the RGWs in the Secondary Cluster just like it was set in the Primary Cluster
5. Run the ceph-ansible playbook on your 2nd cluster
+6. **(Optional)** Edit the rgws.yml in group_vars for rgw related pool creation
+
+```
+rgw_create_pools:
+ "{{ rgw_zone }}.rgw.buckets.data":
+ pg_num: 64
+ size: ""
+ type: ec
+ ec_profile: myecprofile
+ ec_k: 5
+ ec_m: 3
+ "{{ rgw_zone }}.rgw.buckets.index":
+ pg_num: 8
+ size: ""
+ type: replicated
+```
+**Note:** The pg_num values should match the values for the rgw pools created on the primary cluster. Mismatching pg_num values on different sites can result in very poor performance.
+
+**Note:** An online pgcalc tool (ex: https://ceph.io/pgcalc) should be used to determine the optimal sizes for the rgw.buckets.data, rgw.buckets.index pools as well as any other pools declared in this dictionary.
+
+7. Run the ceph-ansible playbook on your 2nd cluster

## Conclusion
You should now have a master zone on cluster0 and a secondary zone on cluster1 in an Active-Active mode.
