This would work If all nodes have a single function only (mon, mgr, old). I tried everything to update the monitors first, but due to the dependencies between the Ceph packages the monitors and mgr daemons can not simply be updated separately from the OSDs What I don't get, though, is that once all three monitors and mgrs are updated the OSDs do not fall back in line after a reboot. I will try to force the install of ceph-base, ceph-common and mon/mgr and then force upgrade the OSDs to test whether that will work. If not at least a workflow should be considered that allows upgrade of hyper converged clusters, which are becoming more and more important for edge sites. On Fri, Apr 24, 2020 at 5:50 PM Dan Hill
