      Support for frisbee direct image upload to fs node. · 99943a19
      Mike Hibler authored
      We have had issues with uploading images to boss where they are then written
      across NFS to ops. That seems to be a network hop too far on CloudLab Utah
      where we have a 10Gb control network. We get occasional transcient timeouts
      from somewhere in the TCP code. With the convoluted path through real and
      virtual NICs, some with offloading, some without, packets wind up getting
      out of order and someone gets far enough behind to cause problems.
      
      So we work around it.
      
      If IMAGEUPLOADTOFS is defined in the defs-* file, we will run a frisbee
      master server on the fs (ops) node and the image creation path directs the
      nodes to use that server. There is a new hack configuration for the master
      server "upload-only" which is extremely specific to ops: it validates the
      upload with the boss master server and, if allowed, fires up an upload
      server for the client to talk to. The image will thus be directly uploaded
      to the local (ZFS) /proj or /groups filesystems on ops. This seems to be
      enough to get around the problem.
      
      Note that we could allow this master server to serve downloads as well to
      avoid the analogous problem in that direction, but this to date has not
      been a problem.
      
      NOTE: the ops node must be in the nodes table in the DB or else boss will
      not validate proxied requests from it. The standard install procedure is
      supposed to add ops, but we have a couple of clusters where it is not in
      the table!

      Yet another layer of backward compat... · afa1569d
      Mike Hibler authored
      If we support provenance but not deltas, then we do not use the
      newer create-versioned-image when creating images from Xen vnodes.
      However, we had a bug in that path where we would then not pass the
      imageid argument to the old script, resulting in us spewing the image
      out to stdout which got put in the logfile.
