VOTEQUORUM_OVERVIECorosync Cluster Engine Programmer's MVOTEQUORUM_OVERVIEW(8)NAMEvotequorum_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.
