ERROR_CLUSTER_NOT_SHARED_VOLUME

ERROR_CLUSTER_NOT_SHARED_VOLUME means the target path is not located on a Cluster Shared Volume (CSV). A CSV-specific operation cannot be applied to ordinary local storage or a non-CSV cluster disk.

Resolve the target path to its owning disk or CSV and verify it with cluster storage commands. If the workflow requires CSV semantics, move or provision the workload on supported CSV storage instead of applying CSV APIs to a normal disk.

What to check

Verify the path and identify the backing disk or volume.
List the cluster shared volumes and confirm the intended disk has been added to CSV.
Do not convert storage to CSV until workload, filesystem, and supported access requirements are verified.
