Returns

Standard Pacemaker return code

Definition at line 113 of file cluster.c.

pcmk_cluster_free()

void pcmk_cluster_free

(

Parameters

[in,out]

cluster

Cluster object to free

Definition at line 160 of file cluster.c.

)

Get a log-friendly string equivalent of a cluster layer.

Parameters

[in]

layer

Cluster layer

Returns

Log-friendly string corresponding to layer

Definition at line 352 of file cluster.c.

pcmk_cluster_new()

pcmk_cluster_t* pcmk_cluster_new

(

void

)

Allocate a new pcmk_cluster_t object.

Returns

A newly allocated pcmk_cluster_t object (guaranteed not NULL)

Note

The caller is responsible for freeing the return value using pcmk_cluster_free().

Definition at line 145 of file cluster.c.

pcmk_cluster_set_destroy_fn()

int pcmk_cluster_set_destroy_fn	(	pcmk_cluster_t *	cluster,
		void(*)(gpointer)	fn
	)

Definition at line 180 of file cluster.c.

pcmk_get_cluster_layer()

enum pcmk_cluster_layer pcmk_get_cluster_layer

(

void

)

Get and validate the local cluster layer.

If a cluster layer is not configured via the PCMK__ENV_CLUSTER_TYPE local option, this will try to detect an active cluster from among the supported cluster layers.

Returns

Local cluster layer

Note

This will fatally exit if the configured cluster layer is invalid.
