But be caution about stop failure of the application migrate trigger stonith. "stonith-enabled=false" could remove such risk.

[ClusterLabs] Safe way to stop pacemaker on both nodes of a two node cluster
Hi, I am confused about the best way to stop pacemaker on both nodes of a two node cluster. The options I know of are 1. Put the cluster in Maintenance Mode, stop the applications manually and then stop pacemaker on both nodes. For this I need the application to be stopped manually 2. Stop pacemaker on one node, wait for all resources to come up on second node, then stop pacemaker on second node. This might cause a significant delay because all resources has to come up on second node. Is there any other way to stop pacemaker on both nodes gracefully ? Thanks in advance.
