DESCRIPTION

       Cluster properties used by Pacemaker's controller, formerly known as crmd

SUPPORTED PARAMETERS

       dc-version = string [none]
           Version of Pacemaker on the cluster's DC.

           Includes the hash which identifies the exact changeset it was built from. Used for
           diagnostic purposes.

       cluster-infrastructure = string [corosync]
           The messaging stack on which Pacemaker is currently running.

           Used for informational and diagnostic purposes.

       cluster-name = string [(null)]
           An arbitrary name for the cluster

           This optional value is mostly for users' convenience as desired in administration, but
           may also be used in Pacemaker configuration rules via the #cluster-name node
           attribute, and by higher-level tools and resource agents.

       dc-deadtime = time [20s]
           How long to wait for a response from other nodes during startup.

           The "correct" value will depend on the speed/load of your network and the type of
           switches used.

       cluster-recheck-interval = time [15min]
           Polling interval for time based changes to options, resource parameters and
           constraints.

           The Cluster is primarily event driven, however the configuration can have elements
           that change based on time. To ensure these changes take effect, we can optionally poll
           the cluster's status for changes. Allowed values: Zero disables polling. Positive
           values are an interval in seconds (unless other SI units are specified. eg. 5min)

       load-threshold = percentage [80%]
           The maximum amount of system resources that should be used by nodes in the cluster

           The cluster will slow down its recovery process when the amount of system resources
           used (currently CPU) approaches this limit

       node-action-limit = integer [0]
           The maximum number of jobs that can be scheduled per node. Defaults to 2x cores

       fence-reaction = string [stop]
           How a cluster node should react if notified of its own fencing

           A cluster node may receive notification of its own fencing if fencing is
           misconfigured, or if fabric fencing is in use that doesn't cut cluster communication.
           Allowed values are "stop" to attempt to immediately stop pacemaker and stay stopped,
           or "panic" to attempt to immediately reboot the local node, falling back to stop on
           failure.

       election-timeout = time [2min]
           *** Advanced Use Only ***.

           If need to adjust this value, it probably indicates the presence of a bug.

       shutdown-escalation = time [20min]
           *** Advanced Use Only ***.

           If need to adjust this value, it probably indicates the presence of a bug.

       join-integration-timeout = time [3min]
           *** Advanced Use Only ***

           If need to adjust this value, it probably indicates the presence of a bug

       join-finalization-timeout = time [30min]
           *** Advanced Use Only ***

           If you need to adjust this value, it probably indicates the presence of a bug

       transition-delay = time [0s]
           *** Advanced Use Only *** Enabling this option will slow down cluster recovery under
           all conditions

           Delay cluster recovery for the configured interval to allow for additional/related
           events to occur. Useful if your configuration is sensitive to the order in which ping
           updates arrive.

       stonith-watchdog-timeout = time [(null)]
           How long to wait before we can assume nodes are safely down

       stonith-max-attempts = integer [10]
           How many times stonith can fail before it will no longer be attempted on a target
