Typedef Documentation

pcmk__scheduler_private_t

typedef struct pcmk__scheduler_private pcmk__scheduler_private_t

Definition at line 68 of file scheduler.h.

Enumeration Type Documentation

pe_quorum_policy

enum pe_quorum_policy

Possible responses to loss of quorum.

Enumerator
pcmk_no_quorum_freeze	Do not recover resources from outside partition.
pcmk_no_quorum_stop	Stop all resources in partition.
pcmk_no_quorum_ignore	Act as if partition still holds quorum.
pcmk_no_quorum_fence	Fence all nodes in partition.
pcmk_no_quorum_demote	Demote promotable resources and stop all others.
no_quorum_freeze	Deprecated Use pcmk_no_quorum_freeze instead
no_quorum_stop	Deprecated Use pcmk_no_quorum_stop instead
no_quorum_ignore	Deprecated Use pcmk_no_quorum_ignore instead
no_quorum_suicide	Deprecated Use pcmk_no_quorum_fence instead
no_quorum_demote	Deprecated Use pcmk_no_quorum_demote instead

Function Documentation

pcmk_find_node()

pcmk_node_t * pcmk_find_node	(	const pcmk_scheduler_t *	scheduler,
		const char *	node_name )

Find a node by name in scheduler data.

Parameters

[in]	scheduler	Scheduler data
[in]	node_name	Name of node to find

Returns

Node from scheduler data that matches node_name if any, otherwise NULL

Definition at line 282 of file scheduler.c.

pcmk_free_scheduler()

void pcmk_free_scheduler

(

pcmk_scheduler_t *

scheduler

)

Free scheduler data.

Parameters

[in,out]

scheduler

Scheduler data to free

Definition at line 193 of file scheduler.c.

pcmk_get_dc()

pcmk_node_t * pcmk_get_dc

(

const pcmk_scheduler_t *

scheduler

)

Definition at line 212 of file scheduler.c.

pcmk_get_no_quorum_policy()

enum pe_quorum_policy pcmk_get_no_quorum_policy

(

const pcmk_scheduler_t *

scheduler

)

Definition at line 226 of file scheduler.c.

pcmk_has_quorum()

bool pcmk_has_quorum

(

const pcmk_scheduler_t *

scheduler

)

Definition at line 264 of file scheduler.c.

pcmk_new_scheduler()

pcmk_scheduler_t * pcmk_new_scheduler

(

void

)

Create a new object to hold scheduler data.

Returns

New, initialized scheduler data, or NULL on memory error

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 pcmk_free_scheduler() when the instance is no longer needed.

Definition at line 32 of file scheduler.c.

pcmk_reset_scheduler()

void pcmk_reset_scheduler

(

pcmk_scheduler_t *

scheduler

)

Reset scheduler data to defaults.

Free scheduler data except the local node name and output object, and reset all other values to defaults, so the data is suitable for rerunning status

Parameters

[in,out]

scheduler

Scheduler data to reset

Definition at line 87 of file scheduler.c.

pcmk_set_scheduler_cib()

int pcmk_set_scheduler_cib	(	pcmk_scheduler_t *	scheduler,
		xmlNode *	cib )

Definition at line 246 of file scheduler.c.
