Nothing is HA if you do it wrong, and there's lots of ways to do HA wrong. Rather than getting emotional and blaming a tool for not meeting your expectation, consider asking for help achieving your goals. You'll learn a lot more and you'll more likely reach your goals.

Could please state directly in the docs that replica isn’t useful to make reliable R/W HA filesystems. There are a ton of web pages that suggest that gluster can be used to make HA filesystems, but that is false.[1] To a normal person replica 2 means that it works when one goes offline. The problem is, if you configure quorums to avoid split brain, because you want a filesystem that works, then when the first replica pair goes offline, you get read-only errors on the filesystem. In the HA world, falling over dead, isn’t what people want. Not configuring a quorum is even worse, as then it isn’t even a reliable filesystem.
Also, please state that by default, because of the quorum setting, the filesystem isn’t reliable when replica is used.
Personally, I’d like a reliable high performance HA filesystem. I was hoping that gluster could be it.
