VOTEQUORUM_GETINFO(3)				    Corosync Cluster Engine Programmer's Manual 			     VOTEQUORUM_GETINFO(3)

NAME
votequorum_getinfo - Get information about the VoteQuorum service SYNOPSIS
#include <corosync/votequorum.h> int votequorum_getinfo(votequorum_handle_t *handle, unsigned int nodeid, struct votequorum_info *info); DESCRIPTION
The votequorum_getinfo function is used to get information about the voting system and its nodes. The nodeid argument indicates which node information should be stored in the votequorum_info structure. The votequorum_info structure is defined as follows: struct votequorum_info { unsigned int node_id; unsigned int node_state; unsigned int node_votes; unsigned int node_expected_votes; unsigned int highest_expected; unsigned int total_votes; unsigned int quorum; unsigned int flags; unsigned int qdevice_votes; char qdevice_name[VOTEQUORUM_QDEVICE_MAX_NAME_LEN]; }; The node_state is defined as: #define VOTEQUORUM_NODESTATE_MEMBER 1 #define VOTEQUORUM_NODESTATE_DEAD 2 #define VOTEQUORUM_NODESTATE_LEAVING 3 The flags are defined as: #define VOTEQUORUM_INFO_TWONODE 1 #define VOTEQUORUM_INFO_QUORATE 2 #define VOTEQUORUM_INFO_WAIT_FOR_ALL 4 #define VOTEQUORUM_INFO_LAST_MAN_STANDING 8 #define VOTEQUORUM_INFO_AUTO_TIE_BREAKER 16 #define VOTEQUORUM_INFO_ALLOW_DOWNSCALE 32 #define VOTEQUORUM_INFO_QDEVICE_REGISTERED 64 #define VOTEQUORUM_INFO_QDEVICE_ALIVE 128 #define VOTEQUORUM_INFO_QDEVICE_CAST_VOTE 256 #define VOTEQUORUM_INFO_QDEVICE_MASTER_WINS 512 The members starting node_ hold information specific to the requested nodeid, the other are general to the voting system.

VOTEQUORUM_QDEVICE_POLL(3)			    Corosync Cluster Engine Programmer's Manual 			VOTEQUORUM_QDEVICE_POLL(3)

NAME
votequorum_qdevice_poll - Tells votequorum the result of the quorum device poll SYNOPSIS
#include <corosync/votequorum.h> int votequorum_qdevice_poll(votequorum_handle_t handle, const char * name, unsigned int cast_vote); DESCRIPTION
The votequorum_qdevice_poll is called by the quorum device subsystem (not provided as part of votequorum) to tell the voting system if the quorum device is present/active or not. If cast_vote is 1 then the votes for the device are included in the quorum calculation, otherwise not. This routine should be called at regular intervals to ensure that the device status is always known to votequorum. If votequorum_qde- vice_poll is not called for (default) 10 seconds then the device will be deemed to be dead and its votes removed from the cluster. This does not unregister the device. The default poll time can be changed by setting the cmap variable quorum.quorumdev_poll. RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned. ERRORS
CS_ERR_TRY_AGAIN Resource temporarily unavailable CS_ERR_INVALID_PARAM Invalid argument CS_ERR_ACCESS Permission denied CS_ERR_LIBRARY The connection failed CS_ERR_INTERRUPT System call inturrupted by a signal CS_ERR_NOT_SUPPORTED The requested protocol/functuality not supported CS_ERR_MESSAGE_ERROR Incorrect auth message received CS_ERR_NO_MEMORY Not enough memory to completed the requested task SEE ALSO
