      Export the disk index in the import/export scripts · 74c47259
      Iustin Pop authored
      We want to export the disk index as some OSes will only want to export
      the first disk (or the second one, etc.), even if we have multiple
      disks.
      
      The patch also updates the backend.ExportSnapshot docstring.

      The newly-added node-specific ValidateParams hypervisor method is
      exported over RPC, using the semi-standard (success, message) return
      value. Multi-node call, so that we call on both primary and secondary at

      Fix a few rpc-related errors · 16ad1a83
      Iustin Pop authored
      This fixes:
        - whitespace change, double lines between methods
        - duplication of call_upload_file, introduced by mistake in rev 1795
          and which went undetected because of the many changes in that ref
          (only diff -b shows it clearly)
        - call_instance_info didn't pass the hypervisor name parameter, but
          the backend requires it

      Abstract checking own address into a function · caad16e2
      Iustin Pop authored
      Currently, we check if we have a given ip address (i.e. it's alive on
      one of our interfaces) but manually calling TcpPing(source=localhost).
      This works, but having it spread all over the code makes it hard to
      change the implementation.
      
      The patch abstracts this into a separate utils.OwnIpAddress(addr)
      function. We add a rpc call for it, which we use instead of the
      (single-use of) call_node_tcp_ping. We leave node_tcp_ping in, as seems
      useful and eventually it should be removed in a separate patch.

      Move the hypervisor attribute to the instances · e69d05fd
      Iustin Pop authored
      This (big) patch moves the hypervisor type from the cluster to the
      instance level; the cluster attribute remains as the default hypervisor,
      and will be renamed accordingly in a next patch. The cluster also gains
      the ‘enable_hypervisors’ attribute, and instances can be created with
      any of the enabled ones (no provision yet for changing that attribute).
      
      The many many changes in the rpc/backend layer are due to the fact that
      all backend code read the hypervisor from the local copy of the config,
      and now we have to send it (either in the instance object, or as a
      separate parameter) for each function.
      
      The node list by default will list the node free/total memory for the
      default hypervisor, a new flag to it should exist to select another
      hypervisor. Instance list has a new field, hypervisor, that shows the
      instance hypervisor. Cluster verify runs for all enabled hypervisor
      types.
      
      The new FIXMEs are related to IAllocator, since now the node
      total/free/used memory counts are wrong (we can't reliably compute the
      free memory).

      Unify SetupDaemon/SetupLogging · 59f187eb
      Iustin Pop authored
      The 'old-style' info, error, debug logs do not make much sense. This
      patch unifies the SetupLogging and SetupDaemon functions. As a result,
      all the commands logs to a 'commands.log' file.
      
      The patch also changes the log setup to keep going if there's an error
      in setting up the file logging but we're logging to stderr.
      
      Also, burnin now logs to its own file (burnin.log).

      This patch adds a new, unused for now, parameter to the start and stop

      Fix double-logging in daemons · ff5fac04
      Iustin Pop authored
      Currently, in debug mode, both the logfile handler and the stderr
      handler will log debug messages. Since the stderr is redirected to the
      same logfile (to catch non-logged errors), it means log entries are
      doubled.
      
      The patch adds an extra parameter to the logger.SetupDaemon() function
      that allows disabling of the stderr logging. The master and node daemon
      will use this to enable stderr logging only when running in foreground.

      Add a rpc call for BlockDev.Close() · d61cbe76
      Iustin Pop authored
      This patch adds rpc layer calls (in rpc.py and the equivalent in
      ganeti-noded) to close a list of block devices, and the wrapper in
      backend.py that takes a list of Disk objects, identifies them and
      returns correctly formatted results.
      
      The reason why this very basic call was missing until now from the rpc
      layer is that we usually don't care about device closes (though we
      should, and will do so in the future) as only drbd has a meaningful
      Close() operation; right now we directly do Shutdown().
      
      The patch is clean enough that it's actually independent of the live
      migration implementation.

      Move iallocator script execution to ganeti-noded · 8d528b7c
      Iustin Pop authored
      Currently the iallocator execution takes place in the master, which is a
      violation of the current architecture, and will create problems with a
      threaded master daemon.
      
      This patch moves the execution to the backend, similar to the hooks
      runner, by:
        - introducing a new class that handles the execution in the backend
          (and could be used also for listing the allocators, etc.)
        - introducing a new rpc call
        - replacing the actual execution in IAllocator.Run() with a rpc call
      
      This passes burnin with the dumb allocator
