GlusterFS developer here.  Sure, we have bugs just like anybody else.  So do you.  Nonetheless, just saying that GlusterFS replication &quot;is not split-brain safe&quot; is FUD.  Neither is yours, not 100%.  Likewise, &quot;static assignment&quot; is simply not true.  We move files around to rebalance capacity, we have tiering, and users can explicitly place a file on a particular node (though the mechanisms for that are clunky and poorly documented).  I&#x27;ve been fair and even complimentary toward XtreemFS in many blog posts and public appearances.  I&#x27;d appreciate the same honesty and courtesy in return.
