Chapter 5. Developer previews
This section describes the developer preview features introduced in Red Hat OpenShift Data Foundation 4.13.
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 the 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. Allow override of the default NooBaa backing store
You can override the default backing store and remove it if you do not want to use the default configuration of backing store by using the manualDefaultBackingStore flag. This provides flexibility to customize your backingstore configuration and tailor it to your specific needs. By leveraging this feature, you can further optimize your system and enhance its performance.
For more information, see the knowledgebase article Allow override of default NooBaa backing store.
5.2. Ability to clone and restore volumes across different Ceph CSI storage classes
You can now clone and restore persistent volume claims (PVCs) across different Ceph CSI managed storage classes. You can take a snapshot of a PVC created with one Ceph CSI storage class and clone it into a PVC created using another Ceph CSI storage class. This ability helps in the following scenarios:
- To reduce the storage footprint
- To move from a storage class with replica 3 to replica 2 or replica 1 where you have your own high availability or underlying storage providing resiliency.
- To clone from a slower storage class to a faster storage class.
- To take a snapshot of an image on a storage class that has lower failure-domain tolerance and clone it to a storage class that has higher failure-domain tolerance
For more information, see the knowledgebase article Ability to clone and restore volumes across different Ceph CSI storage classes.
5.3. Enable external mode using SSL with RADOS Gateway
OpenShift Data Foundation now provides in-transit encryption for object storage between OpenShift Data Foundation and Red Hat Ceph Storage when using external mode. This enables Multicloud Object Gateway to use SSL when in external mode.
For more information, see the knowledgebase article Setting up TLS-enabled RGW in external Red Hat Ceph Storage for OpenShift Data Foundation.
5.4. Allow ocs-operator to deploy active and standby MGR pods
OpenShift Data Foundation now allows ocs-operator to deploy two MGR pods, one of them is active and the other is a standby. This helps to improve the reliability of MGR pods.
For more information, see the knowledgebase article Allowing ocs-operator to deploy two MGR PODs active and standby.
5.5. Network File System support for Active Directory and FreeIPA
In addition to LDAP, OpenShift Data Foundation provides Network File System (NFS) support for Active Directory and FreeIPA. This helps with better control of access management and leveraging of existing tools.
For more information, see the knowledgebase article Setting up Ceph NFS-Ganesha and using a Windows AD for user ID lookups.
