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. | |
| 18 | ||
| 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. | |
