Hi,
An arbiter volume is a special class of replica-3 volume. Arbiter is
special because the third brick of replica set contains only directory
hierarchy information and metadata. Therefore, arbiter provides
split-brain protection with the equivalent consistency of a replica-3
volume without incurring the additional storage space overhead.
If you already have a replica volume in your config with three
bricks then that config should be good. You do not need to create a
arbiter.
Hope this helps !!
Thanks
kasturi
