VOTEQUORUM_QDEVICE_MASTER_WINS(3) Corosync Cluster Engine Programmer's Manual VOTEQUORUM_QDEVICE_MASTER_WINS(3)
NAME
votequorum_qdevice_master_wins - Sets or clears quorum device master_wins flag
SYNOPSIS
#include <corosync/votequorum.h>
int votequorum_qdevice_master_wins(votequorum_handle_t handle const char name, unsigned int allow);
DESCRIPTION
The votequorum_qdevice_master_wins informs votequorum whether or not the currently registered qdevice subsystem supports 'master_wins' mode
(default 0). This mode allows the qdevice to effectively take over the quorum calculations of votequorum. Any node with an active qdevice
that also has master_wins set becomes quorate regardless of the node votes of the cluster. It is left up to the qdevice subsystem itself
(not part of votequorum) to communicate across the nodes or otherwise provide some system of deciding which nodes will be part of the quo-
rate cluster, if any. eg They may be the set of nodes that has access to a quorum disk.
name The name of the currently registered quorum device on this node. This must match the existing name known to votequorum.
allow 0 (the default) means that master_wins is not active on this node. 1 means that master_wins is active on this node.
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
