ERROR_CLUSTER_RESOURCE_VETOED_MOVE_NOT_ENOUGH_RESOURCES_ON_SOURCE - 5958 (0x1746)

Technical Background

This error code is specific to the Windows Cluster Service and indicates that a move operation between two nodes was vetoed due to insufficient resources on the source node. The Cluster Service manages resource groups and their distribution across nodes in a cluster environment.

Error Details

The ERROR_CLUSTER_RESOURCE_VETOED_MOVE_NOT_ENOUGH_RESOURCES_ON_SOURCE error is generated when a resource manager or a cluster service component determines that there are not enough available resources to successfully complete the move operation. This can include various types of resources such as CPU, memory, disk space, network bandwidth, and others depending on the specific resource being managed.

Common Causes

• Insufficient free resources (CPU, memory, disk space) on the source node.
• Resource constraints that prevent the move from completing successfully.
• Configuration issues within the cluster service or resource manager.

Real-World Context

In a clustered environment, resources are often shared and managed across multiple nodes. When a move operation is initiated, the Cluster Service checks if the target node can accommodate the resource without violating any resource constraints. If the source node does not have enough free resources to support the move, it will veto the operation.

Is This Error Critical?

The criticality of this error depends on the specific application or service that requires the moved resource. In some cases, the operation may be retried with different parameters or at a later time when more resources are available. However, in other scenarios, this could indicate a more severe issue requiring administrative intervention.

How to Diagnose

1. Review Operation Context: Ensure that the move operation is being performed under appropriate conditions and within the expected operational context.
2. Validate Parameters: Verify that all parameters passed to the move operation are correct and valid.
3. Confirm Object Types: Confirm that the resource type and object types involved in the move operation are correctly identified and managed by the cluster service.

How to Resolve

1. Correct Parameter Usage: Ensure that all parameters used in the move operation are within acceptable limits and constraints.
2. Adjust Operation Context: If possible, adjust the operational context or environment to provide more resources on the source node before retrying the move operation.
3. Restore Data: In cases where data integrity is compromised due to resource limitations, restore the data from a backup or another reliable source.

Developer Notes

Developers should ensure that their applications and services are designed to handle potential resource constraints gracefully. This includes implementing retry logic with exponential backoff and monitoring system resources to prevent such errors.

FAQ

Q: What does the error code 0x1746 mean?

A: The error code 0x1746, or ERROR_CLUSTER_RESOURCE_VETOED_MOVE_NOT_ENOUGH_RESOURCES_ON_SOURCE, indicates that a move operation between two nodes was vetoed due to insufficient resources on the source node.

Q: How can I prevent this error from occurring?

A: Ensure that your cluster environment has sufficient free resources and that resource constraints are properly managed. Implement monitoring and alerting for resource usage to proactively address potential issues.

Summary

The ERROR_CLUSTER_RESOURCE_VETOED_MOVE_NOT_ENOUGH_RESOURCES_ON_SOURCE error is a specific condition in the Windows Cluster Service where a move operation between nodes was vetoed due to insufficient resources on the source node. This error requires careful diagnosis and resolution, often involving resource management adjustments or operational context changes.
