Hello Paul, I didn't skip this step. Actually I'm sure that everything on Cluster is on Nautilus because I had issues with SLES 12SP2 Clients that failed to connect due to outdated client tools that could not connect to Nautilus. Would it make sense to execute ceph osd require-osd-release nautilus again?
