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.
