      Added support for the new current_reloads table - this table is intended · 455dcee9
      Robert Ricci authored
      to contain a list of reloads currently in processes. It is filled by
      os_load, and is cleared out by the tmcd 'reset' command or by nfree.
      The tmcd 'loadaddr' command now uses this table instead of the reloads table.
      
      Also added Frisbee support to sched_reload, and changed the Frisbee command
      line option to os_load to '-r' to avoid a conflict with sched_reload's '-f'
      option.

      Changes to nfree in how scheduled reloads are handled. Instead of · 2007505d
      Leigh B. Stoller authored
      firing off an os_load, just move the node from its current reservation
      to emulab-ops/reloadpending. This moves the operation out of band from
      the user's perspective (he gets more immediate response when an
      experiment ends, and besides we cannot handle mass reloads anyway, and
      so this approach is unusable until Frisbee.
      
      Change the reload_daemon to look for free nodes that need a reload (as
      before) *and* nodes in emulab-ops/reloadpending (as put there by nfree).
      In this case, the imageid comes from the reloads table instead of the
      node-types table. I also updated the reload_daemon to use libdb routines.
      
      Also change testbed/reloading to emulab-ops/reloading. Maybe someday
      I'll remove these hardwired strings.

      Added sched_reserve. Works kind of like sched_reload, but for a reservation. · e1f4263c
      Mac Newbold authored
      Rob and I noticed that when we need to do maintainance to a node, its hard
      to grab it when it gets freed before it gets taken again. So this will allow
      admins to set up nodes so that when the current owner frees them, they
      immediately are moved into another experiment. For instance, if I need to do
      an upgrade on all the machines in the testbed, I can do:
      
      sched_reserve testbed down pc1 pc2 pc3 [...] pc40
      
      and it will immediately reserve any free nodes, skip any that are already
      in testbed/down, and add an entry to the next_reserve table for any nodes
      that are already reserved. Then nfree checks for entries in the next_reserve
      table before it lets any nodes go (much like it does for the reloads table),
      and moves them into the expt before it can get reserved again. So we can
      guarantee that the next time a node is freed, it will be saved for us.
      
      Note that this can also be useful to accumulate nodes for a large experiment,
      since you can make sure you get them as soon as the current owner is done.

      A slew of changes for new images/os_info tables. disk_images is gone, · e39b61a2
      Leigh B. Stoller authored
      replaced by the "images" table. New os_info table is added. New web
      pages to add and delete OSIDs to/from the os_info table, for use in
      the NS file. tb-create-os is gone. handle_os no longer operates on the
      tbcmds file, and no longer writes anything into the ir file. Moved the
      setting up of os state (nodes table) from os_setup to handle_os, where
      it should be. os_load and sched_reload now take a single argument, the
      name of the imageid from the images table.

      A set of change for exporting project and user directories only to · 407cd1ac
      Leigh B. Stoller authored
      machines in the experiment. exports_setup runs on paper and queries
      the DB, generating a set of export lines. That is sent over to
      plastic, and piped into exports_setup.proxy, which generates a new
      /etc/exports file and restarts mountd. All of the client setup scripts
      have been changed to mount the project and user directories.
