&quot;Split brain safety&quot; is not a commonly used term, and even if that weren&#x27;t the case I&#x27;d say it&#x27;s not a term that should be thrown around lightly.  Also, using Paxos or Raft doesn&#x27;t guarantee split-brain safety, as aphyr has proven over and over again with Jepsen.  So what we have is two systems that take different approaches to quorum and split brain and all that.  It seems a bit disingenuous to throw stones at the older open-source project while ignoring the potential for the exact same problems in the newer proprietary one.<p>FWIW, I do think the current Gluster approach to replication is not <i>sufficiently</i> resistant to split-brain in the all-important edge cases.  That&#x27;s why I&#x27;ve been working on a new approach, much more like Ceph and many other systems - though few of them use Paxos in the I&#x2F;O path.  That&#x27;s wasteful.  Other methods such as chain or splay replication are sufficient, with better performance, so they&#x27;re more common.
