      Allow 'add instance' to not start the new instance · bdd55f71
      Iustin Pop authored
      This patch allows 'gnt-instance add' to not start the newly-created
      instance. It also allow 'gnt-instance add' and 'gnt-backup import' to
      not check for IP conflicts (only when not starting the instance).

      Change resolved hostname from dict to a class · bcf043c9
      Iustin Pop authored
      The current result of utils.LookupHostname() is a dict, but this does
      not allow static checkers to check the correctness of the code. This
      patch introduces a new class names HostInfo and changes LookupHostname
      to return an instance of this class; this allows better checking of the
      code (and also the code is cleaner).

      Implement cluster rename operation · 07bd8a51
      Iustin Pop authored
      This patch adds a new OpCode (and corresponding LU) that implements the
      cluster rename functionality.
      
      This is done by shutting down the master role, making the needed sstore
      modifications and distributing the changed files to all nodes, and then
      re-enabling the master role.
      
      The modification to the man page of gnt-cluster also moves the section
      on gnt-cluster destroy in order to correct alphabetical ordering.

      Remove OpQueryNodeData and LUQueryNodeData · 4a72cc75
      Iustin Pop authored
      Now that LUQueryNodes supports all the functionality of LUQueryNodeData,
      let's migrate gnt-node.ShowNodeConfig to use it and remove all traces of
      OpQueryNodeData and LUQueryNodeData.

      Change LUQueryNodes to return raw values and support selective listing · ec223efb
      Iustin Pop authored
      LUQueryNodes it's very similar to LUQueryNodeData, but it lacks two
      features:
        - instance list (it has count though), both primary and secondary
        - selective node listing
      
      In order to support these features, we change it to return raw values
      instead of stringified ones (like the recent change to LUQueryInstances)
      and to support query-ing of a restricted set of nodes.
      
      This CL also modifies the gnt-node script to conform to the new protocol
      and the opcode OpQueryNodes to support the new "nodes" attribute.

      Change _GetWanted* to return names instead of objects · a7ba5e53
      Iustin Pop authored
      On closer look, all except one of the current users of _GetWantedNodes are
      using only the name of the nodes and throw away the other attributes. It makes
      sense to make this function return only the name list (as in the future this
      might be faster than computing all attributes).

      Move string formatting out of LUQueryInstances · 8a23d2d3
      Iustin Pop authored
      Currently, LUQueryInstances will provide strings for its results. This makes it
      hard for other consumers than "gnt-instance list" to use the OpQueryInstances
      opcode for whatever they wish to.
      
      The change moves the formatting in five of the six cases where this happens to
      the actual gnt-instance.ListInstances procedure and removes the unconditional
      convert to string in LUQueryInstances.Exec()

      Rework ssh known-hosts handling. · 82122173
      Iustin Pop authored
      This changes:
        - cluster setup, we no longer edit /etc/ssh/ssh_known_hosts but our
          own file
        - node add, we no longer remove root's known_hosts (twice)
        - gnt-instance console, both the LU and the script: since now the ssh
          setup is not standard, we need to build the ssh cmdline in the LU
          (instead of manually building it in the script) with the correct
          parameters and use the command line as returned in the script
        - ssh.py, many changes, split options in module-level constants so
          that building the command line in different places is easier/more
          logical
        - backend.py, we no longer remove root's known_hosts in Add node, and
          we allow our own known_hosts file to be uploaded

      Improve LURunClusterCommand · 02715459

      This function used a hand-coded ssh call to remote nodes. Fix it to use the
      ssh.SSHCall function, and in the process drop the command field from the
      results, as it's too verbose and we can use (in gnt-cluster) what we passed in.

      if the master netdev does not exist.

      Style changes for pep-8 and python-3000 compliance. · 3ecf6786
      Iustin Pop authored
      This changes the raising of exceptions from:
        raise Exception, value
      to
        raise Exception(value)
      
      as the first form will be removed in python-3000 and the second form is
      preferred now.
      
      The changes also involve a few cases of changing from raising standard
      exceptions and use our own ones.
      
      The new version also fixes many pylint-generated warnings, especially in
      ganeti-noded where I changed many methods to @staticmethod.
      
      There is no functionality changed (barring any bugs).

      Big change/cleanup in relation to the master startup: · 880478f8
      Iustin Pop authored
        - move the master node name from the ConfigWriter to SimpleStore (all
          nodes need this, and it was the only thing pulled in from the
          ConfigWriter on nodes)
        - fix mcpu.py and the testing w.r.t. this change; for testing, rename
          the fake_config.py to mocks.py and add a FakeSStore object
        - then add a ganeti-master script which can be run on any node at boot
          and which will not do anything if not master on start (on stop it
          will still try to remove the ip address)
        - also add a new cluster-wide variable (master_netdev) that determines
          on which interface we add this ip address; it's customizable at
          cluster init time
        - also remove the cluster name file which was separately handled from
          ssconf (not needed anymore)
        - remove the master init.d links from the list of config files as this
          is not our responsibility now
