[Gluster-users] un-expected warning message when atempting to build a 4 node gluster setup.

[Thing]

Hi,

I am on centos 7.4 with gluster 4.

I am trying to a distributed and replicated volume on the 4 nodes

I am getting this un-expected qualification,

[***@glustep1 brick1]# gluster volume create gv0 replica 2
glusterp1:/bricks/brick1/gv0 glusterp2:/bricks/brick1/gv0
glusterp3:/bricks/brick1/gv0 glusterp4:/bricks/brick1/gv0

8><----

Replica 2 volumes are prone to split-brain. Use Arbiter or Replica 3 to
avoid this. See:
http://docs.gluster.org/en/latest/Administrator%20Guide/Split%20brain%20and%20ways%20to%20deal%20with%20it/
.
Do you still want to continue?
(y/n) n

8><-----

Looking at both gluster docs and redhat docs this seems un-expected.

regards

Steven

This warning was introduced from glusterfs 3.11 onward to encourage
people to move away from replica 2 and use arbiter (or replica 3)
instead.  If you are okay with the split-brain issues inherent in
replica 2, you can still go ahead and create it.

Ravi
