I’m going to work on setting up a test environment to see how it behaves, but can anybody answer a few questions?<br><br>1. is cluster.halo-enabled a global setting? Or does it only apply to certain volumes in the TSP?<o:p></o:p></p><p class=MsoNormal>2. cluster.halo-min-replicas: How does this interact with a traditional gluster volume create command? What replica levels are recommended? Does it work with or need Arbiter?<o:p></o:p></p><p class=MsoNormal>3. Related to above: assuming you have 5 nodes per site (if you were doing distributed/replicate with Arbiter previously), what halo-min-replicas setting is recommended?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p></div>
