Issue

  • How can I temporarily disable rgmanager status checks against a service so that I can perform maintenance on the resources without causing a service failure?
  • For maintenance it is needed to temporarily stop a resource that is part of a cluster service, but the rest of the service should remain running
  • When stopping a resource that is part of a cluster service, rgmanager automatically starts the resource again when it detects it has stopped
  • How to freeze cluster services during network outages or maintenance?

Environment

  • Red Hat Enterprise Linux (RHEL) 5 Update 3 or later with the High Availability Add On
  • Red Hat Enterprise Linux Server (RHEL) 6 with the High Availability Add On
