VOTEQUORUM_QDEVICE_UPDATE(3) Corosync Cluster Engine Programmer's Manual VOTEQUORUM_QDEVICE_UPDATE(3) NAME
votequorum_qdevice_update - Updates quorum device name SYNOPSIS
#include <corosync/votequorum.h> int votequorum_qdevice_update(votequorum_handle_t handleconst char oldname, const char newname); DESCRIPTION
The votequorum_qdevice_update is used to change the name of the quorum device to corosync. The name of q quorum device is purely informa- tional and has no significance to votequorum itself, but it's useful for the name (displayed by corosync-quorumtool) to reflect the actual device contributing votes to quorum to avoid user confusion.

VOTEQUORUM_QDEVICE_POLL(3) Corosync Cluster Engine Programmer's Manual VOTEQUORUM_QDEVICE_POLL(3) NAME
votequorum_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. ERRORS
