   @nepfag We were doing this with VAX clusters back in the 80s.

      @nepfag "VAXclusters reached the point where the cluster as a whole essentially never went down. Rolling upgrades even allowed the system operators to upgrade the OpenVMS system software, shutting down, upgrading, and rebooting individual nodes while the cluster as a whole continued processing. Cluster uptimes are frequently measured in years with the current longest uptime being at least sixteen years." https://en.wikipedia.org/wiki/VMScluster
