+== NooBaa pvPool scaling
+
+When using clusters with more than 3 workers, both the number of pvPool volumes
+and the per-pod resource requests/limits need to be configured. Otherwise
+workloads like Quay that consume object storage will fail.
+
+Set all of the following in your AgnosticV catalog item:
+
+[source,yaml]
+----
+# Scale pvPool volumes to match worker node count
+ocp4_workload_external_odf_backingstore_pv_volumes: "{{ worker_instance_count | int }}"
+
+# Enable custom resource requests/limits for each BackingStore pod
