VOTEQUORUM_QDISK_POLL(3) Corosync Cluster Engine Programmer's Manual VOTEQUORUM_QDISK_POLL(3)NAME
votequorum_qdisk_poll - Tells votequorum the result of the quorum device poll
SYNOPSIS
#include <corosync/votequorum.h>
int votequorum_qdisk_poll(votequorum_handle_t handle, unsigned int state);
DESCRIPTION
The votequorum_qdisk_poll is called by the quorum device subsyetem (not provided as part of votequorum) to tell the voting system if the
qurum device is present/active or not. If state 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_qdisk_poll
is not called after (default) 10 seconds then the device will be deeded 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 object database variable quorum.quorumdev_poll.
RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned.
ERRORS
The errors are undocumented.

VOTEQUORUM_QDISK_REGISTER(3) Corosync Cluster Engine Programmer's Manual VOTEQUORUM_QDISK_REGISTER(3)NAME
votequorum_qdisk_register - Registers a new quorum device
SYNOPSIS
#include <corosync/votequorum.h>
int votequorum_qdisk_register(votequorum_handle_t handle, char * name, unsigned int votes);
DESCRIPTION
The votequorum_qdisk_register is used to register a new quorum device. A quorum device is an external way of adding votes to a small clus-
ter. 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_qdisk_poll must be called for the votes to be included in the quorum
calculation.
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.
ERRORS
The errors are undocumented.

Was wondering if anyone would entertain the idea of creating open source voting software--seems like as this issue moves forward we have an opportunity and the ability to build a powerful worldwide tool to secure voting rights for everyone (2 Replies)
Hi all,
I would like to ensure that a volume group has an effective quorum setting of 1 (or off). I know you can change the quorum setting using the chvg -Q command but want to know if the setting has been changed before the vg was varied on or a reboot.
In other words how can I ensure that... (3 Replies)
