ERROR_RESOURCE_FAILED
The resource is failed; find the first resource-specific cause
Failover Clustering monitors resource health and calls resource DLL entry points such as Online, Offline, LooksAlive, and IsAlive. Microsoft documents that a failed LooksAlive check can trigger IsAlive for a more complete health check. A failed resource is therefore the result of resource-specific health or lifecycle processing.
The status does not identify the application fault by itself. The useful diagnostic sequence begins with the first resource event before the failure, then follows recovery, restart, or group failover actions taken by the cluster.
What to inspect
- Capture the resource type, owner group, owner node, and state before manually restarting anything.
- Review the resource-specific application or service logs together with FailoverClustering events and Cluster.log.
- If the resource repeatedly fails health checks, repair the underlying workload or resource DLL condition rather than only increasing restart thresholds.
