      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()

      Fix the ssh change which breaks remote ssh commands · 72f0f7fd
      Iustin Pop authored
      Explanation: since we use lists and not a string, every argument we give
      is passed unchanged to the remote shell. So, for example, passing
      '/etc/init.d/ganeti restart' to the remote shell, it will try to run the
      path /etc/init.d/ganeti\ restart. With the s space included. This
      breaks, for example, gnt-node add and gnt-cluster command.
      
      The original problem with the backup routines that led to the "'" change
      is that they use a plain " ".join(list), but we don't need to quote the
      whole ssh remote command for this. We can simply use the existing
      utils.ShellQuoteCmd(list) which does the proper quoting of the ';' or
      '&&' metacharacters.
      
      With this change, both gnt-node add, gnt-cluster command and
      export/import work.
      
      This also improves the error-handling behaviour of one cat command by
      making it conditional on the preceding mkdir.

      Make import/export use the auxiliary ssh library to build the remote commands. · 00003458
      Guido Trotter authored
      This avoids forgetting some parameters, as it's happening right now 
      (the correct known host file is not being passed)
      
      In order to do so we split SSHCall into an auxiliary BuildSSHCmd which builds
      the command but doesn't actually call it, and SSHCall itself which runs RunCmd
      on top of BuildSSHCmd's result. BuildSSHCmd is then explicitely called by 
      import/export who has to build a more complex command to be run later.

      Switch utils.RunCmd from popen2 to subprocess · 113b55aa
      Iustin Pop authored
      This changes the implementation of RunCmd from using the popen2 module
      to using the (new in 2.4) subprocess module.
      
      This is helpful because the subprocess module has more advanced features
      than popen2, the most important ones being the ability to run code in the
      child process before the exec and ability to launch with modified
      environment.

      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

      This function used a hand-coded ssh call to remote nodes. Fix it to use the
