10 garbd [options] [group address]

12
14 garbd joins Galera cluster as an additional node for the purpose of es‐
15 tablishing quorum in case of network partitioning. It can do so by
16 serving:
17 a) as an odd node to prevent split-brains;
18 b) as a reference connection point outside a datacenter.
19 Arbitrator node must see all messages that the other nodes of the clus‐
20 ter see, however it does not process them any further and just discards
21 them. As such it does not store any cluster state and can't be used to
22 bootstrap the cluster, so it only can join existing cluster.
