Volume to store vm

[Cristian Del Carlo <cristian.delcarlo@xxxxxxxxxxxxxxxxxx>]

Hi,

I have an environment consisting of 4 nodes ( with large disks).
I have to create a volume to contain image of virtual machines.

In documentation i read:
Hosting virtual machine images requires the consistency of three-way replication,
which is provided by three-way replicated volumes, three-way distributed replicated volumes,
arbitrated replicated volumes, and distributed arbitrated replicated volumes.

So I'm going to confusion to configure this volume.
I have 4 nodes and I don't want to lose space by dedicating one to the function of arbiter.

Would it be reasonable to configure the volume as in these two examples?

# gluster volume create test1 replica 3 \
server1:/bricks/brick1 server2:/bricks/brick1 server3:/bricks/brick1 \
server2:/bricks/brick2 server3:/bricks/brick2 server4:/bricks/brick2 \
server3:/bricks/brick3 server4:/bricks/brick3 server1:/bricks/brick3 \
server4:/bricks/brick4 server1:/bricks/brick4 server2:/bricks/brick4

# gluster volume create test1 replica 3 arbiter 1 \
server1:/bricks/brick1 server2:/bricks/brick1 server3:/bricks/arbiter_brick1 \
server2:/bricks/brick2 server3:/bricks/brick2 server4:/bricks/arbiter_brick2 \
server3:/bricks/brick3 server4:/bricks/brick3 server1:/bricks/arbiter_brick3 \
server4:/bricks/brick4 server1:/bricks/brick4 server2:/bricks/arbiter_brick4

Thanks,
