I know that this question has been asked in this forum a few years back but I wanted to see if the answer changed since the newer releases of AOS. In my case, I’m running AOS version 5.15.4 LTS and found that our 7-node cluster was configured for RF3 - although most of our containers are RF2 (the exceptions being the “NutanixManagementShare: and “SelfServiceContainer” containers).
Since most of our containers are only RF2 I’m not too concerned about extra overhead but was curious if AOS now supports the switchback from RF3 on the cluster.
