10.7. Cluster-Controlled Services Fails to Migrate

If a cluster-controlled service fails to migrate to another node but the service will start on some specific node, check for the following conditions.
  • Ensure that the resources required to run a given service are present on all nodes in the cluster that may be required to run that service. For example, if your clustered service assumes a script file in a specific location or a file system mounted at a specific mount point then you must ensure that those resources are available in the expected places on all nodes in the cluster.
  • Ensure that failover domains, service dependency, and service exclusivity are not configured in such a way that you are unable to migrate services to nodes as you'd expect.
  • If the service in question is a virtual machine resource, check the documentation to ensure that all of the correct configuration work has been completed.
  • Increase the resource group manager's logging, as described in 節 10.6, “Cluster Service Will Not Start”, and then read the messages logs to determine what is causing the service start to fail to migrate.
