The logical volume manager storage (LVMS) supports persistent volume claim (PVC) cloning for logical volume manager (LVM) thin volumes. A clone is a duplicate of an existing volume that can be used like any other volume. When provisioned, an exact duplicate of the original volume is created if the data source references a source PVC in the same namespace. After a cloned PVC is created, it is considered a new object and completely separate from the source PVC. The clone represents the data from the source at the moment in time it was created.
注意
Cloning is only possible when the source and destination PVCs are in the same namespace. To create PVC clones, you must configure thin volumes on the RHEL for Edge host.
