Chapter 4. Developer previews
This section describes the developer preview features introduced in Red Hat OpenShift Data Foundation 4.17.
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.
4.1. Multi-Volume Consistency for Backup - CephFS
Provides crash consistent multi-volume consistency groups for backup solutions to be used by applications that are deployed over multiple volumes. This provides support for OpenShift Virtualization and helps to better support applications.
For an example, see the knowledgebase article, Enabling Consistency Groups for CephFS Workloads.
4.2. Efficient SELinux volume relabelling for all access modes
OpenShift Data Foundation now supports efficient SELinux volume relabelling for all access modes. The context set for SELinux in the PodSpec or container is used by the driver to mount the volume directly with the correct SELinux labels. This feature helps to eliminate the need to recursively relabel the volume and pod startup can be significantly faster.
For more information, see the knowledgebase article, SELinux relabeling using mount options (RWX).
4.4. Access buckets with DNS subdomain style (Virtual host style) for RGW
Virtual-host-style S3 bucket addressing can be configured for OpenShift Data Foundation internal mode object stores and ObjectBucketClaims. The client access is secured with TLS using OpenShift builtin platform certificates.
