ERROR_CORE_RESOURCE
Core cluster resources have protected lifecycle rules
Failover Clustering maintains infrastructure resources used by the cluster itself. These core objects are different from application resources added to a clustered role. Deleting one through an ordinary resource-removal path could remove functionality required for cluster identity or core operation.
Identify the resource type and owning group before deciding that the object is stale. A cluster core resource should be changed through the feature-specific workflow that owns it, such as quorum or administrative access point configuration.
What to inspect
- List the resource, ResourceType, and OwnerGroup to determine whether it belongs to cluster core infrastructure.
- Check quorum and cluster access-point configuration before modifying core resources.
- Do not use registry edits or unsupported force-removal techniques to bypass core-resource protection.
