VOTEQUORUM_QDEVICECorosyncWCluster Engine ProVOTEQUORUM_QDEVICE_MASTER_WINS(3)NAMEvotequorum_qdevice_master_wins - Sets or clears quorum device mas‐
ter_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 quorate clus‐
ter, if any. eg They may be the set of nodes that has access to a quo‐
rum 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.
