   1 Corosync-qdevice
   2 ----------------
   3 corosync-qdevice is a daemon running on each node of a cluster. It provides
   4 a configured number of votes to the quorum subsystem based on a third-party
   5 arbitrator's decision. Its primary use is to allow a cluster to sustain more
   6 node failures than standard quorum rules allow. It is recommended for clusters
   7 with an even number of nodes and highly recommended for 2 node clusters.
   8
   9 corosync-qnetd is a daemon running outside of the cluster with the purpose
  10 of providing a vote to the corosync-qdevice model net. It's designed to
  11 support multiple clusters and be almost configuration and state free.
  12 New clusters are handled dynamically and no configuration file exists.
  13 It's also able to run as non-root user - which is recommended.
  14 Connection between the corosync-qdevice model net client can be optionally
  15 configured with TLS client certificate checking. The communication protocol
  16 between server and client is designed to be very simple and allow
  17 backwards compatibility.

  19 Originally both qdevice and qnetd were part of the Corosync codebase
  20 (https://github.com/corosync/corosync) but because it's got quite big we
  21 decided to split it into it's own sub project.
