Updated: Feb 21, 2026
Technical Meaning
The error code ERROR_CLUSTER_NODE_DRAIN_IN_PROGRESS (5962, 0x174A) is returned when a node drain operation is already in progress within a Windows Failover Cluster. This indicates that the system is currently performing an evacuation of resources from one or more nodes to ensure a smooth transition and maintenance.
Error Details
This error code is specific to cluster management operations, particularly those related to node maintenance and failover scenarios. It signifies that the requested operation cannot proceed because another node drain operation is already underway. This state can occur during planned maintenance activities where resources are being moved from a node to ensure its safe removal from the cluster.
Usage Context
The ERROR_CLUSTER_NODE_DRAIN_IN_PROGRESS error code is typically encountered in scenarios involving cluster management tools and APIs, such as the Failover Cluster Manager or PowerShell cmdlets for managing clusters. Developers should be aware that attempting to initiate a node drain operation when one is already active will result in this error.
Developer Interpretation
When encountering ERROR_CLUSTER_NODE_DRAIN_IN_PROGRESS, developers should understand that the current state of the cluster does not allow for the requested operation due to an ongoing node drain. This error code can be used to inform users or applications that a different action is required, such as waiting until the current operation completes before proceeding with another task.
Related Errors
ERROR_CLUSTER_NODE_NOT_FOUND(0x8024D01E): Indicates that the specified node could not be found in the cluster.ERROR_CLUSTER_INVALID_REQUEST(0x8024D035): Indicates an invalid request was made to the cluster, which may include attempting to drain a node during an incompatible state.
FAQ
Q: What does ERROR_CLUSTER_NODE_DRAIN_IN_PROGRESS mean?
A: It means that a node drain operation is already in progress and cannot be initiated again until it completes.
Q: Can this error occur outside of cluster management tools?
A: No, this specific error code is related to Windows Failover Clusters and will not appear in other contexts within the operating system.
Summary
The ERROR_CLUSTER_NODE_DRAIN_IN_PROGRESS (5962) error code indicates that a node drain operation is already active. Developers should handle this error by either waiting for the current operation to complete or by adjusting their operations accordingly.
