cephrgw-operator v0.4.0 adds immutable placementTarget selection on Buckets; the nine CNPG backup buckets should live on the ec (4/1) placement instead of 3-replica. Existing buckets cannot change placement, so after this merges the buckets get deleted and recreated on ec and fresh base backups are triggered (day-old backups are accepted losses, per Ben). - bump cephrgw-operator image and CRD ref to v0.4.0 - add placementTarget: ec to all nine cnpg backup Bucket CRs Reviewed-on: #312 Co-authored-by: Ben Vincent <ben@unkin.net> Co-committed-by: Ben Vincent <ben@unkin.net>

# Ceph RGW (S3) backup target for the artifactapi CNPG cluster, provisioned by the

# in-estate cephrgw-operator. One dedicated bucket + owner user per cluster:
|
|
# cephrgw CRs are namespace-scoped and CNPG reads its S3 credential Secret from
|
|
# its own namespace, so backups are per-database rather than one shared bucket.
