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

NAME
votequorum_qdevice_register - Registers a new quorum device SYNOPSIS
#include <corosync/votequorum.h> int votequorum_qdevice_register(votequorum_handle_t handle, const char * name); DESCRIPTION
The votequorum_qdevice_register is used to register a new quorum device. A quorum device is an external way of adding votes to a small cluster. The quorum device is, in effect, a pseudo node in the cluster that provide votes based on some external device, usually a shared disk partition or perhaps a network router. This call creates the device but does not mark it active. votequorum_qdevice_poll must be called for the votes to be included in the quo- rum calculation. name is string containing an informative name for the quorum device. It is simply stored by votequorum and used in the display of corosync- quorumtool, it can be a maximum of 254 characters. The number of votes contributed by the quorum device is already known to votequorum, it is set in cmap quorum.device.votes and not by the device. Note that it is the responsibility of the quorum device subsystem (not provided as part of votequorum) to keep all nodes informed of the quorum device status. RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned. ERRORS

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
