Closing the loop in case someone does a search on this... I have an update. I am getting some time on 1,000 node soon so I have started to validate jumping to gluster 7.2 on my small lab machine.
I switched the packages to my own build of gluster 7.2 with gnfs. I re-installed my leader node (gluster/gnfs servers) and created the volumes the same way as before. This includes heavy cache optimization for the NFS services volume. I can no longer duplicate this problem on gluster 7.2. I was able to duplicate rebalance troubles on NFS clients every time on gluster 4.1.6. I do have a couple questions on some rebalance errors, which I will send in a separate email.
