NAME

6       votequorum_qdevice_poll  -  Tells  votequorum  the result of the quorum
7       device poll

SYNOPSIS

10       #include <corosync/votequorum.h>
11
12       int votequorum_qdevice_poll(votequorum_handle_t handle,  const  char  *
13       name, unsigned int cast_vote, votequorum_ring_id_t ring_id);
14

DESCRIPTION

16       The  votequorum_qdevice_poll  is  called by the quorum device subsystem
17       (not provided as part of votequorum) to tell the voting system  if  the
18       quorum  device  is  present/active  or  not. If cast_vote is 1 then the
19       votes for the device are included in the quorum calculation,  otherwise
20       not.   Current  ring_id  must  be  set (one get in votequorum_notifica‐
21       tion_fn callback) otherwise poll is ignored.  This  routine  should  be
22       called  at regular intervals to ensure that the device status is always
23       known to votequorum.  If  votequorum_qdevice_poll  is  not  called  for
24       (default)  10  seconds  (or  30 seconds for sync phase) then the device
25       will be deemed to be dead and its votes removed from the cluster.  This
26       does  not  unregister the device.  The default poll time can be changed
27       by setting the cmap variable quorum.device.timeout for normal operation
28       or quorum.device.sync_timeout for synchronization phase.
