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 quorate cluster, if any. eg They may be the set of nodes that has access to a quorum disk. .br .B name The name of the currently registered quorum device on this node. This must match the existing name known to votequorum. .br .B allow 0 (the default) means that master_wins is not active on this node. 1 means that master_wins is active on this node. .SH RETURN VALUE This call returns the CS_OK value if successful, otherwise an error is returned. .PP .SH ERRORS .PP .B CS_ERR_TRY_AGAIN Resource temporarily unavailable .B CS_ERR_INVALID_PARAM Invalid argument .B CS_ERR_ACCESS Permission denied .B CS_ERR_LIBRARY The connection failed .B CS_ERR_INTERRUPT System call interrupted by a signal .B CS_ERR_NOT_SUPPORTED The requested protocol/functionality not supported .B CS_ERR_MESSAGE_ERROR Incorrect auth message received .B CS_ERR_NO_MEMORY Not enough memory to complete the requested task .SH "SEE ALSO" .BR votequorum_overview (3), .BR votequorum_initialize (3), .BR votequorum_finalize (3), .BR votequorum_getinfo (3), .BR votequorum_trackstart (3), .BR votequorum_trackstop (3), .BR votequorum_fd_get (3), .BR votequorum_dispatch (3), .BR votequorum_context_set (3), .BR votequorum_context_get (3), .BR votequorum_setexpected (3), .BR votequorum_setvotes (3), .BR votequorum_qdevice_register (3), .BR votequorum_qdevice_poll (3), .BR votequorum_qdevice_update (3), .PP
