ERROR_CLUSTER_SINGLETON_RESOURCE

ERROR_CLUSTER_SINGLETON_RESOURCE means the cluster allows only one instance of this resource type. Creating a second independent instance is not supported by that resource type.

What to check

  • List existing resources of the same type and determine which one already owns the required function.
  • Check whether the new configuration should reuse the existing resource rather than create another one.
  • Read the resource type documentation before attempting to bypass the restriction.
