Hey folks, I'm having an issue with name collision of rgw zones across different realms in three multi-site clusters. Clusters are setup with bi-directional multi-site peering in addition to a local realm in each cluster for container images and thanos metrics. All clusters are running Reef v18.2.2 The local realm's `default` zone from the primary cluster's multi-site realm `cloud` was added to the period map by mistake and it propogated to the replica clusters. The zone name collided with the existing `default` zone in the `default` realm. I see the default zone in both pcloud and default realms with the same UUID. When I run `radosgw-admin period get --rgw-realm default` on the replica clusters, it returns with no zones or zonegroups when it should have one each named `default`. In a test cluster, I tried renaming or deleting the `default` zone from the multi-site realm but it knocks out any zones named `default` regardless of realm. ### Primary cluster (west coast) goneill@us-west-2-ceph-mon1:~$ sudo radosgw-admin period get --rgw-realm default | jq -r '.period_map.zonegroups[].zones[] | [.id, .name, .endpoints[]] | @tsv' 37929bb2-2eb3-4827-952a-6b5ca05627a6 default http://us-west-2-ceph-mon1:8080 goneill@us-west-2-ceph-mon1:~$ sudo radosgw-admin period get --rgw-realm savagebucket | jq -r '.period_map.zonegroups[].zones[] | [.id, .name, .endpoints[]] | @tsv' 250a2a20-5e11-486b-bae4-e29b173d2556 thanos 107d29a0-b732-4bf1-a26e-1f64f820e839 us-east-1-prod http://us-east-1-ceph-rgw1:8080 1e27bf9c-3a2f-4845-85b6-33a24bbe1c04 us-west-2-corp http://us-west-2-ceph-rgw1:8080 331d3f1e-1b72-4c56-bb5a-d1d0fcf6d0b8 us-west-1-prod http://us-west-1-ceph-rgw1:8080 37929bb2-2eb3-4827-952a-6b5ca05627a6 default ### Replica cluster (west coast) goneill@us-west-1-ceph-mon1:~$ sudo radosgw-admin period get --rgw-realm default | jq -r '.period_map.zonegroups[].zones[] | [.id, .name, .endpoints[]] | @tsv' goneill@us-west-1-ceph-mon1:~$ sudo radosgw-admin period get --rgw-realm savagebucket | jq -r '.period_map.zonegroups[].zones[] | [.id, .name, .endpoints[]] | @tsv' 250a2a20-5e11-486b-bae4-e29b173d2556 thanos 107d29a0-b732-4bf1-a26e-1f64f820e839 us-east-1-prod http://us-east-1-ceph-rgw1:8080 1e27bf9c-3a2f-4845-85b6-33a24bbe1c04 us-west-2-corp http://us-west-2-ceph-rgw1:8080 331d3f1e-1b72-4c56-bb5a-d1d0fcf6d0b8 us-west-1-prod http://us-west-1-ceph-rgw1:8080 37929bb2-2eb3-4827-952a-6b5ca05627a6 default ### Replica cluster (east coast) goneill@us-east-1-ceph-mon1:~$ sudo radosgw-admin period get --rgw-realm default | jq -r '.period_map.zonegroups[].zones[] | [.id, .name, .endpoints[]] | @tsv' goneill@us-east-1-ceph-mon1:~$ sudo radosgw-admin period get --rgw-realm savagebucket | jq -r '.period_map.zonegroups[].zones[] | [.id, .name, .endpoints[]] | @tsv' 250a2a20-5e11-486b-bae4-e29b173d2556 thanos 107d29a0-b732-4bf1-a26e-1f64f820e839 us-east-1-prod http://us-east-1-ceph-rgw1:8080 1e27bf9c-3a2f-4845-85b6-33a24bbe1c04 us-west-2-corp http://us-west-2-ceph-rgw1:8080 331d3f1e-1b72-4c56-bb5a-d1d0fcf6d0b8 us-west-1-prod http://us-west-1-ceph-rgw1:8080 37929bb2-2eb3-4827-952a-6b5ca05627a6 default
