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_overview - Votequorum Library Overview
OVERVIEW
The votequorum library is delivered with the corosync project. It is the external interface to the vote-based quorum service. This service
is optionally loaded into all nodes in a corosync cluster to avoid split-brain situations. It does this by having a number of votes
assigned to each system in the cluster and ensuring that only when a majority of the votes are present, cluster operations are allowed to
proceed.
The library provides a mechanism to:
* Query the quorum status
* Get a list of nodes known to the quorum service
* Receive notifications of quorum state changes
* Change the number of votes assigned to a node
* Change the number of expected votes for a cluster to be quorate
* Connect an additional quorum device to allow small clusters to remain quorate during node outages.
BUGS
No known bugs at the time of writing. The authors are from outerspace. Deal with it.

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)
