I can't figure out the relation between the number of bricks and replica count.
I have 4 server nodes and after running the command to create a distributed replicated volume, with a replica count of 2, the following message appears:
"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/."
The documentation also says
"The number of bricks should be equal to of the replica count for a replicated volume."
Would it make sense to choose a replica count of 3 in this case? As far as I understand, this would only make sense if I had 6 server nodes - Is it because it makes more sense to say we have a file replicated across 3 replica volumes (considering node1-2, node3-4 and node5-6 are the 3 replica volumes)?
