Red Hat Summit2.12. Shallow volumes support for snapshot or clone
With this release, PVC creation from snapshot functionality in OpenShift Data Foundation supports shallow volumes. These shallow volumes act as a reference to the source subvolume snapshot with no actual new subvolume being created in CephFS. The supported access mode for the shallow volume is ReadOnlyMany. When such PVCs are mounted, it means that the respective CephFS subvolume snapshot is exposed to the workloads. These shallow volumes help to reduce the time and resources to create clones.
참고
It is not possible to take a snapshot of the ROX PVC and creating a ROX PVC clone from ROX PVC results in a pending state. This is an expected behavior.
