How can I leave a resource in the configuration but no longer monitor it or have the cluster manage it in a Pacemaker cluster?

Solution Verified - Updated -

Issue

  • I need to perform maintenance on a resource and don't want pacemaker to run status checks. Is there a way to leave it running but just stop monitoring it?
  • I want to manually manage the state of a resource, but don't want to take it out of the configuration.
  • If I disable a resource in a group, then the rest of the group becomes unmanageable. Is there a way to tell pacemaker to stop managing a resource as part of its group temporarily?
  • Does umanaged persist across restarts and reboots?
  • The cluster service is having SAPDatabase resource which was set as unmanaged, but still pacemaker was performing monitor operations on it which had caused a resource failure and triggered a service relocation.
  • Resource is unmanaged but cluster still moved it when it failed 3 times
  • After marking a resource as unmanaged, is it also required to manually disable monitoring on it?
