Replication data between two machines only

[gonzalez.al at ikusi.es (Gonzalez Tolaretxipi, Alain)]

Hello everyone, 

Is it possible to replicate data between two machines with GlusterFS?
But only two physical machines. I have tested with three machines and it
works (two servers glusterfsd and a client glusterfs). 

Is it possible with two machines? 

Thanks
