Function Documentation

crm_cluster_connect()

gboolean crm_cluster_connect

(

crm_cluster_t *

cluster

)

Connect to the cluster layer.

Parameters

[in,out]

Initialized

cluster object to connect

Returns

TRUE on success, otherwise FALSE

Definition at line 75 of file cluster.c.

crm_cluster_disconnect()

void crm_cluster_disconnect

(

crm_cluster_t *

cluster

)

Disconnect from the cluster layer.

Parameters

[in,out]

cluster

Cluster object to disconnect

Definition at line 101 of file cluster.c.

crm_peer_uname()

const char* crm_peer_uname

(

const char *

uuid

)

Get the node name corresponding to a node UUID.

Parameters

[in]

uuid

UUID of desired node

Returns

name of desired node

Note

This relies on the remote peer cache being populated with all remote nodes in the cluster, so callers should maintain that cache.

Definition at line 250 of file cluster.c.

crm_peer_uuid()

const char* crm_peer_uuid

(

crm_node_t *

peer

)

Get (and set if needed) a node's UUID.

Parameters

[in,out]

peer

Node to check

Returns

Node UUID of peer, or NULL if unknown

Definition at line 38 of file cluster.c.

CRM_TRACE_INIT_DATA()

CRM_TRACE_INIT_DATA

(

cluster

)

get_cluster_type()

enum cluster_type_e get_cluster_type

(

void

)

Get (and validate) the local cluster type.

Returns

Local cluster type

Note

This will fatally exit if the local cluster type is invalid.

Definition at line 325 of file cluster.c.

get_local_node_name()

const char* get_local_node_name

(

void

)

Get the local node's name.

Returns

Local node's name

Note

This will fatally exit if local node name cannot be known.

Definition at line 184 of file cluster.c.

get_node_name()

char* get_node_name

(

uint32_t

nodeid

)

Get the node name corresponding to a cluster node ID.

Parameters

[in]

nodeid

Node ID to check (or 0 for local node)

Returns

Node name corresponding to nodeid

Note

This will fatally exit if nodeid is 0 and local node name cannot be known.

Definition at line 204 of file cluster.c.

is_corosync_cluster()

gboolean is_corosync_cluster

(

void

)

Check whether the local cluster is a Corosync cluster.

Returns

TRUE if the local cluster is a Corosync cluster, otherwise FALSE

Definition at line 389 of file cluster.c.

name_for_cluster_type()

const char* name_for_cluster_type

(

enum cluster_type_e

type

)

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

Parameters

[in]

type

Cluster type

Returns

Log-friendly string corresponding to type

Definition at line 304 of file cluster.c.

pcmk_cluster_free()

void pcmk_cluster_free

(

crm_cluster_t *

cluster

)

Free a crm_cluster_t object and its dynamically allocated members.

Parameters

[in,out]

cluster

Cluster object to free

Definition at line 141 of file cluster.c.

pcmk_cluster_new()

crm_cluster_t* pcmk_cluster_new

(

void

)

Allocate a new crm_cluster_t object.

Returns

A newly allocated crm_cluster_t object (guaranteed not NULL)

Note

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

Definition at line 127 of file cluster.c.

send_cluster_message()

gboolean send_cluster_message	(	const crm_node_t *	node,
		enum crm_ais_msg_types	service,
		const xmlNode *	data,
		gboolean	ordered
	)

Send an XML message via the cluster messaging layer.

Parameters

[in]	node	Cluster node to send message to
[in]	service	Message type to use in message host info
[in]	data	XML message to send
[in]	ordered	Ignored for currently supported messaging layers

Returns

TRUE on success, otherwise FALSE

Definition at line 162 of file cluster.c.

set_uuid()

void set_uuid	(	xmlNode *	xml,
		const char *	attr,
		crm_node_t *	node
	)

Definition at line 400 of file cluster.c.
