NAME¶
crmd - CRM Daemon Options
SYNOPSIS¶
[dc-version=string] [cluster-infrastructure=string] [cluster-name=string] [dc-deadtime=time] [cluster-recheck-interval=time] [notification-agent=string] [notification-recipient=string] [load-threshold=percentage] [node-action-limit=integer] [fence-reaction=string] [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]
DESCRIPTION¶
This is a fake resource that details the options that can be configured for the CRM Daemon.
SUPPORTED PARAMETERS¶
dc-version = string [none]
Includes the hash which identifies the exact changeset it was built from. Used for diagnostic purposes.
cluster-infrastructure = string [heartbeat]
Used for informational and diagnostic purposes.
cluster-name = string [(null)]
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]
The "correct" value will depend on the speed/load of your network and the type of switches used.
cluster-recheck-interval = time [15min]
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)
notification-agent = string [/dev/null]
Use alert path in alerts section instead
notification-recipient = string []
Use recipient value in alerts section instead
load-threshold = percentage [80%]
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]
fence-reaction = string [stop]
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]
If need to adjust this value, it probably indicates the presence of a bug.
shutdown-escalation = time [20min]
If need to adjust this value, it probably indicates the presence of a bug.
crmd-integration-timeout = time [3min]
If need to adjust this value, it probably indicates the presence of a bug.
crmd-finalization-timeout = time [30min]
If you need to adjust this value, it probably indicates the presence of a bug.
crmd-transition-delay = time [0s]
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)]
stonith-max-attempts = integer [10]
