pacemaker default behavior changed
This document (7014282) is provided subject to the disclaimer at the end of this document.
This change was needed because the DLM and all services depending on it such as cLVM2 and OCFS2 cannot work properly if stonith-enabled is set to false. They will silently fail and block forever in case of a node failure or split-brain scenario that cannot be resolved without fencing. So these services should not start (to avoid data corruption) if stonith is explicitly disabled.
This stonith-enabled check can be overridden by configuring the parameter
in the DLM resource, allowing the resource to start even if stonith-enabled is set to false. However this is not recommended for production environments.
