VOTEQUORUM_QDEVICE_MASTER_WINS(3)
Corosync Cluster Engine Programmer's Manual
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 quorate 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.
