NAME

       garbd - arbitrator daemon for Galera cluster

SYNOPSIS

       garbd [options] [group address]

DESCRIPTION

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