Gluster Peer Probe
Establishes a peer relationship between the specified appliances in the grid. You should create all the gluster peers by linking all the appliances back to one master peer node as gluster will automatically create all the rest of the peer relationships. Gluster has a peer-to-peer design but if you try linking appliances A->B then B->C you can get errors whereas linking appliances as A->B then A->C will succeed and link together everything as A<->B, A<->C, and B<->C automatically.
