ERROR_CLUSTER_SHARED_VOLUME_REDIRECTED - 5966 (0x174E)
CSVFS failed operation as volume is in redirected mode.
Updated: Feb 21, 2026
Technical Meaning
The error code ERROR_CLUSTER_SHARED_VOLUME_REDIRECTED (0x174E) indicates that a CSVFS (Cluster Shared Volume File System) operation failed because the volume is in redirected mode. This implies that the operation attempted to modify or access the volume while it was being managed by another node in a cluster, which is not allowed.
Error Details
CSVFS manages shared volumes across multiple nodes in a Windows Failover Cluster. When a volume is in redirected mode, it means that the volume's state has been altered such that direct access to the volume from other nodes is no longer possible or appropriate. This can occur due to various reasons, including maintenance operations or changes in the cluster configuration.
Usage Context
This error typically occurs when an application or system attempt to perform a write operation on a CSVFS-managed volume while it is in redirected mode. The operation will fail with this specific error code, indicating that the requested action cannot be completed due to the current state of the volume.
Developer Interpretation
Developers should interpret this error as an indication that the operation they attempted was not allowed under the current configuration or state of the CSVFS-managed volume. This could mean that the volume is being managed by another node, or it might be in a maintenance state where direct access is restricted.
