Limitations

As opposed to known issues, limitations are functionality restrictions that are part of the predefined system design and capabilities in a particular version.

Volume snapshot limitations

The following limitations apply when using volume snapshots with the IBM block storage CSI driver:

When deleting a PersistentVolumeClaim (PVC), the persistent volume (PV) remains until all snapshots of the specific PV are deleted.
When using the CSI (Container Storage Interface) driver with Spectrum Virtualize Family products, a snapshot can only be used to provision a new volume of equal size.
