That's not how I interpret documentation. 5. Verify that the cluster re-detected all resources correctly. Which implies that after full restart cluster is not aware of previous application state and relies on normal probing. > There has been a "stop cluster" thread recently.

It works with target state; so this would mean either setting target-role of each individual resource to Stopped which is impractical or setting global resource defaults which is unreliable as they may be overridden. >> >> Is there any other way to stop pacemaker on both nodes gracefully ? > > Not a perfect one, I'm afraid. > > Regards, > Ulrich > > >> Thanks in advance. >> >> Thanks & Regards >> >> Dileep Nair >> Squad Lead ‑ SAP Base >> Togaf Certified Enterprise Architect >> IBM Services for Managed Applications >> +91 98450 22258 Mobile >> dilen...@in.ibm.com >> >> IBM Services > > > > _______________________________________________ > Manage your subscription: > https://lists.clusterlabs.org/mailman/listinfo/users > > ClusterLabs home: https://www.clusterlabs.org/ > _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
