- Corosync-qdevice
- ----------------
- corosync-qdevice is a daemon running on each node of a cluster. It provides
- a configured number of votes to the quorum subsystem based on a third-party
- arbitrator's decision. Its primary use is to allow a cluster to sustain more
- node failures than standard quorum rules allow. It is recommended for clusters
- with an even number of nodes and highly recommended for 2 node clusters.
- corosync-qnetd is a daemon running outside of the cluster with the purpose
- of providing a vote to the corosync-qdevice model net. It's designed to
- support multiple clusters and be almost configuration and state free.
- New clusters are handled dynamically and no configuration file exists.
- It's also able to run as non-root user - which is recommended.
- Connection between the corosync-qdevice model net client can be optionally
- configured with TLS client certificate checking. The communication protocol
- between server and client is designed to be very simple and allow
- backwards compatibility.
- Originally both qdevice and qnetd were part of the Corosync codebase
- (https://github.com/corosync/corosync) but because it's got quite big we
- decided to split it into it's own sub project.
