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.
