3 data nodes + 1 arbiter node is possible?

[Mimikoo]

Hello.

I want to have 3 data replica nodes, plus fourth glusterfs node as arbiter for this three data nodes. Is this possible?

Currently I have 3 replica data nodes only. When I want to add the arbiter I get the error:

> gluster volume add-brick www replica 4 arbiter 1 IP:/path
For arbiter configuration, replica count must be 3 and arbiter count must be 1. The 3rd brick of the replica will be the arbiter

Three data nodes and one arbitration node cannot be combined together.

@Mimikoo technically, if you are doing a experiment, it is possible. But with currently available glusterd configurations its not possible.

If you test these templates using external management layer like https://github.com/kadalu/moana you may try to test such configurations.
