VOTEQUORUM_QDEVICECorosync Cluster Engine ProgrammerVOTEQUORUM_QDEVICE_POLL(3)NAMEvotequorum_qdevice_poll - Tells votequorum the result of the quorum
device poll
SYNOPSIS
#include <corosync/votequorum.h>
int votequorum_qdevice_poll(votequorum_handle_t handle, const char *
name, unsigned int cast_vote);
DESCRIPTION
The votequorum_qdevice_poll is called by the quorum device subsystem
(not provided as part of votequorum) to tell the voting system if the
quorum device is present/active or not. If cast_vote is 1 then the
votes for the device are included in the quorum calculation, otherwise
not. This routine should be called at regular intervals to ensure that
the device status is always known to votequorum. If votequorum_qde‐
vice_poll is not called for (default) 10 seconds then the device will
be deemed to be dead and its votes removed from the cluster. This does
not unregister the device. The default poll time can be changed by
setting the cmap variable quorum.quorumdev_poll.
RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is
returned.
