The cluster shared volume is not locally mounted on this node.
Updated: Feb 21, 2026
Introduction
This article provides a detailed explanation of the ERROR_CSV_VOLUME_NOT_LOCAL error, including its technical meaning and developer interpretation. The error code 5951 (0x173F) is associated with issues related to cluster shared volumes not being locally mounted on a specific node.
Technical Meaning
The ERROR_CSV_VOLUME_NOT_LOCAL error indicates that the system has attempted to access or operate on a cluster shared volume, but this volume is not currently mounted on the local node. This can occur in scenarios where multiple nodes are part of a cluster and one or more volumes are shared among these nodes.
Error Details
- Error Name: ERROR_CSV_VOLUME_NOT_LOCAL
- Numeric Code: 5951 (0x173F)
- Short Description: The cluster shared volume is not locally mounted on this node.
This error typically arises when a process or operation requires access to a cluster shared volume, but the volume is not available on the current node. This can be due to various reasons such as network issues, configuration errors, or operational states of the nodes in the cluster.
Usage Context
The ERROR_CSV_VOLUME_NOT_LOCAL error is relevant in scenarios where applications or services rely on cluster shared volumes for data storage and access. It can occur during file operations, directory manipulations, or any other operation that requires the presence of a specific volume within the local node's context.
Developer Interpretation
Developers should interpret this error as an indication that the required cluster shared volume is not available on the current node. This might necessitate checking the configuration and state of the nodes in the cluster, ensuring network connectivity, or verifying the mount status of the volumes.
Related Errors
- ERROR_CSV_VOLUME_DOES_NOT_EXIST: Indicates that a specified cluster shared volume does not exist.
- ERROR_CSV_NODE_DOWN: Indicates that a node is down and cannot serve requests for cluster shared volumes.
- ERROR_CSV_NO_QUORUM: Indicates that the quorum required to access a cluster shared volume is not available.
FAQ
Q: What causes ERROR_CSV_VOLUME_NOT_LOCAL?
A: This error can occur due to various reasons, such as network issues preventing the local node from accessing the cluster shared volume, incorrect configuration of the nodes in the cluster, or operational states where the required volumes are not mounted on the current node.
Q: How can I resolve ERROR_CSV_VOLUME_NOT_LOCAL?
A: To resolve this error, ensure that the necessary cluster shared volumes are properly configured and mounted on the local node. Check network connectivity between nodes, verify the configuration settings, and ensure that all required services are running correctly.
Summary
The ERROR_CSV_VOLUME_NOT_LOCAL error (0x173F) is a specific technical issue related to the availability of cluster shared volumes on a particular node within a Windows cluster environment. Developers should interpret this error as an indication that the required volume is not locally mounted and take appropriate steps to resolve the underlying configuration or operational issues.
