NAME

crmd - CRM Daemon Options

SYNOPSIS

[dc-version=string] [cluster-infrastructure=string] [dc-deadtime=time] [cluster-recheck-interval=time] [load-threshold=percentage] [node-action-limit=integer] [election-timeout=time] [shutdown-escalation=time] [crmd-integration-timeout=time] [crmd-finalization-timeout=time] [crmd-transition-delay=time] [stonith-watchdog-timeout=time] [stonith-max-attempts=integer] [expected-quorum-votes=integer]

DESCRIPTION

This is a fake resource that details the options that can be configured for the CRM Daemon.

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 [heartbeat]

The messaging stack on which Pacemaker is currently running.

Used for informational and diagnostic purposes.

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

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.

crmd-integration-timeout = time [3min]

*** Advanced Use Only ***.

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

crmd-finalization-timeout = time [30min]

*** Advanced Use Only ***.

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

crmd-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

expected-quorum-votes = integer [2]

The number of nodes expected to be in the cluster

Used to calculate quorum in openais based clusters.
