      Remove requirement that host names are FQDN · 89e1fc26
      Iustin Pop authored
      We currently require that hostnames are FQDN not short names
      (node1.example.com instead of node1). We can allow short names as long
        - we always resolve the names as returned by socket.gethostname()
        - we rely on having a working resolver
      These issues are not as big as may seem, as we only did gethostname() in
      a few places in order to check for the master; we already required
      working resolver all over the code for the other nodes names (and thus
      requiring the same for the current node name is normal).  The patch
      moves some resolver calls from within execution path to the checking
      path (which can abort without any problems). It is important that after
      this patch is applied, no name resolving is called from the execution
      path (LU.Exec() or other code that is called from within those methods)
      as in this case we get much better code flow.
      This patch also changes the functions for doing name lookups and
      encapsulates all functionality in a single class.
      The final change is that, by requiring working resolver at all times, we
      can change the 'return None' into an exception and thus we don't have to
      check manually each time; only some special cases will check
      (ganeti-daemon and ganeti-watcher which are not covered by the
      generalized exception handling in cli.py). The code is cleaner this way.

      Move a constant from ganeti-master to constants.py · 619fdc8e
      Iustin Pop authored
      The EXIT_NODESETUP_ERROR is a useful constant and ganeti-watcher could
      use it too. This patch moves it to constants.py and modifed the
      ganeti-master script to use it from there.

      Ask for confirmation when touching multiple instances · 804a1e8e

      This patch makes the new startup/shutdown multi-instance operations to

      Improve the cli.AskUser() function · 47988778
      Iustin Pop authored
      This patch improves the AskUser function by allowing it to:
       - choose from multiple choices (instead of only y/n)
       - give help to the user
       - preserve line breaks and whitespace formatting in the message
      With this patch, an instance removal looks like this:
      root@xen-test1-4:~# gnt-instance remove tsetest1
      This will remove the volumes of the instance tsetest1 (including
      mirrors), thus removing all the data of the instance. Continue?
      y/[n]/?: ?
       y - Perform the operation
       n - Do not perform the operation
      This will remove the volumes of the instance tsetest1 (including
      mirrors), thus removing all the data of the instance. Continue?
      y/[n]/?: y
      The patch also removed the _ask_user member of the opts argument, since
      external code was using it (and thus it makes no sense for it to be a
      private member); now gnt-* scripts are using the AskUser function

      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

      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.

        - "gnt-instance startup --node name..." will work on all instances

          having primary node one of the passed names
        - "gnt-instance startup --secondary name..." will work on all
          instances having as secondary node one of the passed names
        - "gnt-instance startup --all" will work on all instances
      This allows a simple cluster-wide shutdown or node shutdown (or
      Note that this version stops at the first error - it will not try to

      "gnt-instance shutdown NAME", because it doesn't parallelize the
      shutdown/startup actions.

      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.
