+* StatefulSet volume zone spreading when using dynamic provisioning is currently not compatible with
+pod affinity or anti-affinity policies.
+
+* If the name of the StatefulSet contains dashes ("-"), volume zone spreading

+* When specifying multiple PVCs in a Deployment or Pod spec, the StorageClass
+needs to be configured for a specific, single zone, or the PVs need to be
+statically provisioned in a specific zone. Another workaround is to use a
+StatefulSet, which will ensure that all the volumes for a replica are
+provisioned in the same zone.
