VOTEQUORUM_QDEVICE_REGISTER(3)			    Corosync Cluster Engine Programmer's Manual 		    VOTEQUORUM_QDEVICE_REGISTER(3)

NAME

       votequorum_qdevice_register - Registers a new quorum device

SYNOPSIS

       #include <corosync/votequorum.h>

       int votequorum_qdevice_register(votequorum_handle_t handle, const char * name);

DESCRIPTION

       The  votequorum_qdevice_register  is  used  to  register a new quorum device. A quorum device is an external way of adding votes to a small
       cluster. The quorum device is, in effect, a pseudo node in the cluster that provide votes based on some external device, usually  a  shared
       disk partition or perhaps a network router.
       This  call creates the device but does not mark it active.  votequorum_qdevice_poll must be called for the votes to be included in the quo-
       rum calculation.
       name is string containing an informative name for the quorum device. It is simply stored by votequorum and used in the display of corosync-
       quorumtool, it can be a maximum of 254 characters.
       The  number  of votes contributed by the quorum device is already known to votequorum, it is set in cmap quorum.device.votes and not by the
       device.
       Note that it is the responsibility of the quorum device subsystem (not provided as part of votequorum) to keep all nodes  informed  of  the
       quorum device status.

RETURN VALUE

       This call returns the CS_OK value if successful, otherwise an error is returned.

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.
