ERROR_CLUSTER_SHARED_VOLUMES_IN_USE

ERROR_CLUSTER_SHARED_VOLUMES_IN_USE means the requested operation cannot proceed while one or more Cluster Shared Volumes are configured. CSVs must be handled through the corresponding CSV workflow, with workloads protected first.

Enumerate active CSVs and workloads before the blocked operation. Drain or migrate dependent workloads and use the CSV-specific maintenance sequence so storage ownership changes do not interrupt shared-volume access.

What to check

Identify every CSV and the workloads using it.
Move or stop affected roles only through a planned maintenance procedure.
If a disk must leave CSV, use the supported CSV management operation and verify the volume returns to Available Storage.
