21.3. Configuring global resource operation defaults

You can change the default value of a resource operation for all resources with the pcs resource op defaults update command.

The following command sets a global default of a timeout value of 240 seconds for all monitoring operations.

# pcs resource op defaults update timeout=240s

The original pcs resource op defaults name=value command, which set resource operation defaults for all resources in previous releases, remains supported unless there is more than one set of defaults configured. However, pcs resource op defaults update is now the preferred version of the command.

Overriding resource-specific operation values

Note that a cluster resource will use the global default only when the option is not specified in the cluster resource definition. By default, resource agents define the timeout option for all operations. For the global operation timeout value to be honored, you must create the cluster resource without the timeout option explicitly or you must remove the timeout option by updating the cluster resource, as in the following command.

# pcs resource update VirtualIP op monitor interval=10s

For example, after setting a global default of a timeout value of 240 seconds for all monitoring operations and updating the cluster resource VirtualIP to remove the timeout value for the monitor operation, the resource VirtualIP will then have timeout values for start, stop, and monitor operations of 20s, 40s and 240s, respectively. The global default value for timeout operations is applied here only on the monitor operation, where the default timeout option was removed by the previous command.

# pcs resource config VirtualIP
 Resource: VirtualIP (class=ocf provider=heartbeat type=IPaddr2)
   Attributes: ip=192.168.0.99 cidr_netmask=24 nic=eth2
   Operations: start interval=0s timeout=20s (VirtualIP-start-timeout-20s)
               monitor interval=10s (VirtualIP-monitor-interval-10s)
               stop interval=0s timeout=40s (VirtualIP-name-stop-interval-0s-timeout-40s)

Changing the default value of a resource operation for sets of resources

You can create multiple sets of resource operation defaults with the pcs resource op defaults set create command, which allows you to specify a rule that contains resource and operation expressions. All of the rule expressions supported by Pacemaker are allowed.

With this command, you can configure a default resource operation value for all resources of a particular type. For example, it is now possible to configure implicit podman resources created by Pacemaker when bundles are in use.

The following command sets a default timeout value of 90s for all operations for all podman resources. In this example, ::podman means a resource of any class, any provider, of type podman.

The id option, which names the set of resource operation defaults, is not mandatory. If you do not set this option, pcs will generate an ID automatically. Setting this value allows you to provide a more descriptive name.

# pcs resource op defaults set create id=podman-timeout meta timeout=90s rule resource ::podman

The following command sets a default timeout value of 120s for the stop operation for all resources.

# pcs resource op defaults set create id=stop-timeout meta timeout=120s rule op stop

It is possible to set the default timeout value for a specific operation for all resources of a particular type. The following example sets a default timeout value of 120s for the stop operation for all podman resources.

# pcs resource op defaults set create id=podman-stop-timeout meta timeout=120s rule resource ::podman and op stop

Displaying currently configured resource operation default values

The pcs resource op defaults command displays a list of currently configured default values for resource operations, including any rules you specified.

The following command displays the default operation values for a cluster which has been configured with a default timeout value of 90s for all operations for all podman resources, and for which an ID for the set of resource operation defaults has been set as podman-timeout.

# pcs resource op defaults
Meta Attrs: podman-timeout
  timeout=90s
  Rule: boolean-op=and score=INFINITY
    Expression: resource ::podman

The following command displays the default operation values for a cluster which has been configured with a default timeout value of 120s for the stop operation for all podman resources, and for which an ID for the set of resource operation defaults has been set as podman-stop-timeout.

# pcs resource op defaults]
Meta Attrs: podman-stop-timeout
  timeout=120s
  Rule: boolean-op=and score=INFINITY
    Expression: resource ::podman
    Expression: op stop
