      An attempt at fixing some encoding issues · 26f15862
      Iustin Pop authored
      This patch unifies the hardcoded re-encoding attempts into a single
      function in utils.py. This function is used to take either an unicode or
      str object and convert it to a ASCII-only str object which can be safely
      displayed and transmitted.
      
      We replace then the current manual re-encodings with this function. In
      mcpu we stop re-encoding the hooks output and instead we do it right at
      the hook generation in backend.py.
      
      This passes on my 'custom' lvs output with non-ASCII chars. But there
      are probably other places we will need to fix.

      cluster init: don't discard the hypervisor · 8f348e36
      Guido Trotter authored
      On cluster init if the user specifies a default hypervisor (with -t)
      which is not in the default list of enabled hypervisors (currently just
      xen-pvm) without explicitely specifying the list we silently override
      the choice.
      
      With this patch we set the list by default to just the required one, and
      we bail out should the list be hand-specified and not contain the
      default one. This still has an issue when the user doesn't specify a
      default hypervisor but specifies a list which doesn't include xen-pvm:
      in this case though we give an error, rather than silently discarding
      choices.

      Enable gnt-cluster modify to hv/beparams · 779c15bb
      Iustin Pop authored
      This patch enables the cluster modify to change:
        - enabled hypervisor list
        - hvparams (per hypervisor)
        - beparams (only the default group)
      
      Syntax:
        gnt-cluster modify -B vcpus=3 -H xen-pvm:no_initrd_path
      
      Validation for parameters is somewhat missing - the individual
      hypervisors will be checked for syntax and validation, but beparams
      doesn't have validation yes (nowhere), it should be added here once we
      have a global method (will come soon).

      Add an interface for the drain flag changes/query · 3ccafd0e
      Iustin Pop authored
      This adds the set/reset in the jqueue and luxi modules, and a way to
      query it in OpQueryConfigValues, and also the comand line interface for
      it:
      $ gnt-cluster queue info
      The drain flag is unset
      $ gnt-cluster queue drain
      $ gnt-cluster queue info
      The drain flag is set
      $ gnt-cluster queue undrain
      $ gnt-cluster queue info
      The drain flag is unset
      
      The choice of making the setting via luxi and not an opcode is that
      opcodes can't be executed when drained, but we don't query via luxi
      since in the future it might become a cluster property as opposed to a
      node one.

      Change SshRunner usage · 56bece1f
      Iustin Pop authored
      Currently the SshRunner uses a SimpleConfigReader instance, however this
      is not best. We change it to use the cluster name directly (and its
      constructor now takes this as parameter, instead of SCR), and its
      callers are change to pass the name directly.
      
      As a consequence, we can now remove the initialization of SCR in
      gnt-cluster (copyfile and command), and instead we query the master for
      the cluster name).

      Rework master startup/shutdown/failover · b1b6ea87
      Iustin Pop authored
      This (big) patch reworks the master startup/shutdown and the fixes the
      master failover.
      
      What does the patch do?
      
      For master start/stop:
        - remove the old ganeti-master script and its associated man page
        - moves the ip start/stop directly into the backend.(Start|Stop)Master
        - adds start/stop of the master/rapi daemon into these functions,
          selectively based on the start/stop arguments
        - makes the master call via rpc StartMaster(start_daemons=False) to
          the local node so that the master IP is started
        - and finally changes the example init.d script to directly start and
          stop all three daemons, since they do the right thing (depending on
          master/not master role)
      
      For master failover:
        - moves the code from LUMasterFailover into bootstrap.MasterFailover,
          since we need to start/stop the master during this operation and
          thus it can't be executed from the master
        - removes the LUMasterFailover and its associated opcode
      
      Notes: ubuntu's /etc/lsb-base-logging.sh is dumb, so the messages 'not
      master' are not seen during startup on non-master nodes.

      Fix gnt-cluster “command” and “copyfile” · b3989551
      Iustin Pop authored
      Since the disabling of forking in the master daemon, the two ssh-based
      subcommands were not working anymore. However, there is no need at all
      for the commands to be run from the master daemon (permissions to read
      the cluster private ssh key notwithstanding), they can be run directly
      from the command line utilities.
      
      The patch removes the two opcodes OpRunClusterCommand and
      OpClusterCopyFile (and their associated LUs) and changes the code in
      ‘gnt-cluster’ to query the list of nodes and run directly the SshRunner
      over the list. As such, all forking is done from the gnt-cluster script,
      and the commands are working again.
