Chapter 5. Technology previews
This section describes the technology preview features introduced in Red Hat OpenShift Data Foundation 4.18 under Technology Preview support limitations.
Technology Preview features are not supported with Red Hat production service level agreements (SLAs), might not be functionally complete, and Red Hat does not recommend using them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
Technology Preview features are provided with a limited support scope, as detailed on the Customer Portal: Technology Preview Features Support Scope.
5.1. Multi-Volume Consistency for Backup - CephFS and block
Multi-volume consistency which provides crash consistent multi-volume consistency groups for backup solutions can be used by applications that are deployed over multiple volumes. This provides support for OpenShift Virtualization and helps to better support applications.
Red Hat OpenShift Data Foundation is the first storage vendor that implements this new and important CSI feature.
For more information, see the knowledgebase article CephFS VolumeGroupSnapshot in OpenShift Data Foundation.
