How To Test
-----------
If we bring down bricks and perform writes in such a way that arbiter
brick is the only source online, writes/reads will be made to fail with
ENOTCONN. See 'tests/basic/afr/arbiter.t' in the glusterfs tree for
examples.
User Experience
---------------
Similar to a normal replica 3 volume. The only change is the syntax in
volume creation. See
<https://github.com/gluster/glusterfs/blob/master/doc/features/afr-arbiter-volumes.md>
Dependencies
