Yes. And, you explained some more details about replica 3 arbiter setups were one can still get splits on it that I think is vey helpful. The documentation is good on the, if do X, you get Y. It would be nice to have a if you want HA with no possibility of split brain, you must do X. If you want HA with the possibility of split brain, you must to Y. This allows one that knows what they want, to read the one sentence (and nothing else), and get HA with no possibility of split brain. If they don’t know what split brain is, then can follow that link and read up on it. And decide if they want it or not. If you link HA to a glossary, you can then define what HA means. Informally, I wanted to define a cluster that can sustain reads and writes without failure with no single point server failure mode. Or put another way, I want to survive any single machine going down. They can read what you define as HA, and see if that meets what they wanted. Thank you for the updates and the information. _______________________________________________ Gluster-users mailing list [email protected] http://www.gluster.org/mailman/listinfo/gluster-users
