Function Documentation

pcmk_controld_api_fail()

int pcmk_controld_api_fail	(	pcmk_ipc_api_t *	api,
		const char *	target_node,
		const char *	router_node,
		const char *	rsc_id,
		const char *	rsc_long_id,
		const char *	standard,
		const char *	provider,
		const char *	type
	)

Ask the controller to fail a resource.

Parameters

[in,out]	api	Controller connection
[in]	target_node	Name of node resource is on
[in]	router_node	Router node for target
[in]	rsc_id	ID of resource to fail

[in]	standard	Standard of resource
[in]	provider	Provider of resource (if any)
[in]	type	Type of resource to fail

Returns

Standard Pacemaker return code

Note

Event callback will get a reply of type pcmk_controld_reply_resource.

Definition at line 556 of file ipc_controld.c.
