Different volumes means different bricks/disks, right?
So, if I would like to have all replicated 3 times (1 disk per server)
with 2 volumes, i have to put at least 2 disks per server?

Any differences between replica2 + arbiter or replica3 without arbiter?
Replica 3 should be more safe, as data are replicated 3 times.
