Detailed Description

Cluster status and scheduling.

Definition in file status.h.

Function Documentation

calculate_active_ops()

void calculate_active_ops	(	const GList *	sorted_op_list,
		int *	start_index,
		int *	stop_index
	)

Definition at line 2628 of file unpack.c.

cleanup_calculations()

void cleanup_calculations

(

pcmk_scheduler_t *

scheduler

)

Reset scheduler data to defaults without freeing it or constraints.

Parameters

[in,out]

scheduler

Scheduler data to reset

Deprecated:

This function is deprecated as part of the API; pe_reset_working_set() should be used instead.

Definition at line 338 of file status.c.

cluster_status()

gboolean cluster_status

(

pcmk_scheduler_t *

scheduler

)

Definition at line 103 of file status.c.

find_operations()

GList* find_operations	(	const char *	rsc,
		const char *	node,
		gboolean	active_filter,
		pcmk_scheduler_t *	scheduler
	)

Definition at line 5038 of file unpack.c.

pe_bundle_replicas()

int pe_bundle_replicas

(

const pcmk_resource_t *

rsc

)

Get the number of configured replicas in a bundle.

Parameters

[in]

rsc

Bundle resource

Returns

Number of configured replicas, or 0 on error

Definition at line 1894 of file bundle.c.

pe_find_node_any()

pcmk_node_t* pe_find_node_any	(	const GList *	nodes,
		const char *	id,
		const char *	uname
	)

Find a node by name or ID in a list of nodes.

Parameters

[in]	nodes	List of nodes (as pcmk_node_t*)
[in]	id	If not NULL, ID of node to find
[in]	node_name	If not NULL, name of node to find

Returns

Node from nodes that matches id if any, otherwise node from nodes that matches uname if any, otherwise NULL

Definition at line 488 of file status.c.

pe_find_node_id()

pcmk_node_t* pe_find_node_id	(	const GList *	nodes,
		const char *	id
	)

Find a node by ID in a list of nodes.

Parameters

[in]	nodes	List of nodes (as pcmk_node_t*)
[in]	id	ID of node to find

Returns

Node from nodes that matches id if any, otherwise NULL

Definition at line 510 of file status.c.

pe_find_resource()

pcmk_resource_t* pe_find_resource	(	GList *	rsc_list,
		const char *	id
	)

Definition at line 453 of file status.c.

pe_find_resource_with_flags()

pcmk_resource_t* pe_find_resource_with_flags	(	GList *	rsc_list,
		const char *	id,
		enum pe_find	flags
	)

Definition at line 459 of file status.c.

pe_free_working_set()

void pe_free_working_set

(

pcmk_scheduler_t *

scheduler

)

Free scheduler data.

Parameters

[in,out]

scheduler

Scheduler data to free

Definition at line 56 of file status.c.

pe_new_working_set()

pcmk_scheduler_t* pe_new_working_set

(

void

)

Create a new object to hold scheduler data.

Returns

New, initialized scheduler data on success, else NULL (and set errno)

Note

Only pcmk_scheduler_t objects created with this function (as opposed to statically declared or directly allocated) should be used with the functions in this library, to allow for future extensions to the data type. The caller is responsible for freeing the memory with pe_free_working_set() when the instance is no longer needed.

Definition at line 34 of file status.c.

pe_reset_working_set()

void pe_reset_working_set

(

pcmk_scheduler_t *

scheduler

)

Reset scheduler data to default state without freeing it.

Parameters

[in,out]

scheduler

Scheduler data to reset

Definition at line 393 of file status.c.

rsc_printable_id()

const char* rsc_printable_id

(

const pcmk_resource_t *

rsc

)

Definition at line 563 of file utils.c.

set_working_set_defaults()

void set_working_set_defaults

(

pcmk_scheduler_t *

scheduler

)

Definition at line 418 of file status.c.
