SUSE Linux Enterprise High Availability Extension 11 Service Pack 3


The Pacemaker update to version 1.1.10 introduces a behavior change that might prevent the DLM resource (ocf:pacemaker:controld) from starting if stonith-enabled is set to false

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.
