Describe the issue:

ODF is sending the S3 requests to the RGWs with the host: rook-ceph-rgw-ocs-external-storagecluster-cephobjectstore.openshift-storage.svc  header, therefore it needs to be defined at the zonegroup configuration [1]. 

Otherwise noobaa SC does not become available, also OBC requests to the RGW SC got stuck in "pending" status  as it get 404 from the RGW:

RGW logs:

Describe the task you were trying to accomplish:

- Integrate external ODF with RHCS 5.x

Suggestions for improvement:

add a note to the doc to add the hostname into the ZG or if there is default zone then add rgw_dns_name.
