Chapter 5. Developer previews
This section describes the developer preview features introduced in Red Hat OpenShift Data Foundation 4.19.
Developer preview feature is subject to Developer preview support limitations. Developer preview releases are not intended to be run in production environments. The clusters deployed with developer preview features are considered to be development clusters and are not supported through the Red Hat Customer Portal case management system. If you need assistance with developer preview features, reach out to the ocs-devpreview@redhat.com mailing list and a member of the Red Hat Development Team will assist you as quickly as possible based on availability and work schedules.
5.1. OpenShift Data Foundation Multus configuration for existing cluster
The existing clusters can be configured to use Multus network, which is useful in situations where network isolation is needed including data plane and control plane separation. For more information, see the knowledgebase article OpenShift Data Foundation Multus support for existing cluster.
5.2. Encryption at rest for existing clusters
The existing internal mode clusters without encryption can transition to use encryption at rest. This is applicable to both dynamic and local storage devices. For more information, see the knowledgebase article, Enabling encryption at rest as a post deployment operation.
5.3. Troubleshooting disaster recovery with ODF CLI commands
Deploying and configuring clusters for disaster recovery is complicated. To verify that the system is configured correctly, a simple application can be deployed and tested for the real disaster recovery flow. The odf dr command makes this verifying easy. Starting with OpenShift Data Foundation 4.19, odf dr command is introduced with two sub commands init and test. For more information, see the knowledgebase article, Testing disaster recovery with odf dr command.
