NAME

7       ter_wins flag

SYNOPSIS

10       #include <corosync/votequorum.h>
11
12       int  votequorum_qdevice_master_wins(votequorum_handle_t  handle   const
13       char name, unsigned int allow);

DESCRIPTION

16       The  votequorum_qdevice_master_wins  informs  votequorum whether or not
17       the currently registered qdevice subsystem supports 'master_wins'  mode
18       (default 0).  This mode allows the qdevice to effectively take over the
19       quorum calculations of votequorum. Any node with an active qdevice that
20       also  has  master_wins set becomes quorate regardless of the node votes
21       of the cluster. It is left up to the qdevice subsystem itself (not part
22       of  votequorum)  to  communicate  across the nodes or otherwise provide
23       some system of deciding which nodes will be part of the  quorate  clus‐
24       ter,  if any. eg They may be the set of nodes that has access to a quo‐
25       rum disk.
26       name The name of the currently registered quorum device on  this  node.
27       This must match the existing name known to votequorum.
28       allow  0  (the  default)  means  that master_wins is not active on this
29       node. 1 means that master_wins is active on this node.
