      Readd node: allow changed primary IP · 1513e2dd
      Iustin Pop authored
      
      
      The primary IP is not used for DRBD disks, only for the job queue and
      internal commands. As such, it's trivial (with a quiet job queue) to
      re-ip the node.
      
      The patch just relaxes the checks in LUAddNode, and manual testing shows
      that live instances on that node keep working, and that cluster verify
      is happy afterwards.

      Add RPC calls to import and export instance data · 1651d116
      Michael Hanselmann authored
      
      
      These RPC calls can be used to start, monitor and stop the instance data
      import/export daemon.

      Add daemon for instance import and export · 2d76b580
      Michael Hanselmann authored
      
      
      This backend daemon for instance import and export will be used to
      transfer instance data to other machines. It is implemented in a generic
      way to support different ways of data input and output. The third-party
      program “socat”, which is already used by the KVM hypervisor abstraction,
      is used to connect to remote machines using SSL/TLS. After starting the
      child processes in a separate process group, the import/export daemon
      monitors their output and updates a status file regularily. This status
      file can then be read by ganeti-noded (not in this patch).
      
      Three I/O methods are supported: Raw disk, file and script. Each of these
      can be used for import and export.
      
      Similar to daemon-util, an incomplete set of tests written in Bash is
      included.
      
      Two future enhancements are planned:
      - Run parts of the command chain as a dedicated user (privilege
        separation).
      - Currently users of this daemon have to poll the status file while data
        is transferred. This is inefficient and creates unnecessary delays. By
        adding “dd” into the chain and sending it SIGUSR1 regularily, we can get
        some statistics, optimize the polling frequenc and even provide the user
        with an ETA (which isn't available with all current methods to
        import/export instance data).
