Can be queried using `SHOW STATUS`.
`sudo mysql --exec "SHOW STATUS LIKE 'wsrep%'"`
**wsrep_cluster_status:**
- Primary; desired state. Primary component (so the cluster is one big component). Quorum of nodes is present.
- Non-Primary; Part of a partition (the non primary one) of nodes, so the cluster is partitioned. Cluster lost quorum.
- Disconnected: The node is not connected to the cluster at all.
