* If you already have a robust permanent keepstore infrastructure, you can set @Containers.LocalKeepBlobBuffersPerVCPU@ to 0 to disable this feature and preserve the previous behavior of sending container I/O traffic to your separately provisioned keepstore servers.
* This feature is enabled only if no volumes use @AccessViaHosts@, and no volumes have underlying @Replication@ less than @Collections.DefaultReplication@. If the feature is configured but cannot be enabled due to an incompatible volume configuration, this will be noted in the @crunch-run.txt@ file in the container log.
+h3. Backend support for vocabulary checking
+
+If your installation uses the vocabulary feature on Workbench2, you will need to update the cluster configuration by moving the vocabulary definition file to the node where @controller@ runs, and set the @API.VocabularyPath@ configuration parameter to the local path where the file was placed.
+This will enable the vocabulary checking cluster-wide, including Workbench2. The @Workbench.VocabularyURL@ configuration parameter is deprecated and will be removed in a future release.
+You can read more about how this feature works on the "admin page":{{site.baseurl}}/admin/metadata-vocabulary.html.
