Event Source: NTFS
Event ID: 55
The file system structure on disk is corrupt and unusable. Please run the chkdsk utility on the volume "Drive_letter:"
However, if you have an incorrectly configured cluster, data corruption may occur. Use of the Microsoft Cluster Configuration Validation Wizard can provide a high level of confidence that your subsequent cluster installation and operation will be successful. The Microsoft Cluster Configuration Validation Wizard, "ClusPrep," is a validation tool that does a complete system inventory and runs focused tests on servers that are configured and ready for Microsoft Server Cluster installation (or, in other words, before the servers are a cluster). For more information about the tool, visit the following Microsoft Web site:
Note The Clusdisk load delay is less than 10 milliseconds. In this short time, the NTFS file system cannot mount. Therefore, this conflict cannot pose a problem to the NTFS file system.
In this situation, the event is logged only when the following conditions are true:
- The computer is running Windows Clustering and is a node in a cluster.
- The event is recorded when the node starts.
Note When there are multiple nodes, the reservation on the disk normally prevents the other nodes from writing to the disk. However, if the nodes are unable to communicate through the cluster networks, then a "split-brain" scenario may occur. A node that is isolated from the other nodes when it is started will not be able to communicate with the owning node and will try to form the cluster itself, which may break the reservation on some or all cluster disks.
