      Verify: fix crash when a node is down · a872dae6
      Guido Trotter authored
      Currently if ganeti-noded doesn't respond on a node gnt-cluster verify will die
      when verifying primary instances for that node. Fix this by just emitting an
      error message if no information about running instances is returned from the
      node.

      Fix misleading error message when checking disks · ad6d3f7d
      Guido Trotter authored
      _CheckDiskConsistency outputs "Can't get any data from node NODE" when no drbd
      is found on the target node. This causes a misleading error message to be
      output for example on failover (when the primary node is down, or the instance
      is not running), stating that no data could be got from the secondary node,
      which scares the user and misleads him. Changing this to "Disk degraded or not
      found on node %s" still reports that something is missing, but on the other
      hand doesn't make the user think the node is down, or has no data at all...

      Right now if you try to failover an instance which is not marked as up the
      operation will fail unless you pass the --ignore-consistency flag because the

      Improve export and fix export-on-norun bug · fb300fb7
      Guido Trotter authored
      Currently gnt-backup export chains the ShutdownInstance and StartupInstance
      opcodes to itself. This works but (a) it's suboptimal, because there's no need
      to deactivate the instance's disks as we are about to restart it anyway, and
      (b) doesn't take care of instances which are already down (and should be). This
      patch takes care of this by just calling the shutdown rpc function instead of
      the whole opcode, and just starting up the instance if it's configured as up in
      the first place.

      failover: only start instance if we should · 12a0cfbe

      Skip HasValidVG when --no-lvm-storage on cluster init · efa14262

      This patch does two things:
      - Remove "vg_name" from _OP_REQP due to the introduction of
        --no-lvm-storage. Since vg_name option has as default now None and is
        only set to the DEFAULT_VG if lvm_storage is enabled, this is needed
      - It changes LUInitCluster.CheckPrereq() to skip _HasValidVG check
        initializing the cluster with --no-lvm-storage. Furthermore it adds to
        the help message the statement of the possibility to use
        --no-lvm-storage if no 'xenvg' volume group is found.

      Change the order of config updates in some LUs · fe482621
      Iustin Pop authored
      In the start and stop instance LUs, the configuration update is done
      right at the end. This means that if, for example, the instance shutdown
      succeeds, but the drive deactivation fails, the next run of the watcher
      will start the instance again, as it's still marked in running mode.
      
      This patch changes these two LUs so that first the update the
      configuration to the desired state, and only then we proceed to update
      the config. This ensures that the state saved is the desired state.
      
      Because the config might be updated even though the LU failed, this
      patch also modifies the mcpu.Processor.ExecOpCode method to run the
      RunConfigUpdate hook in a finally: phase while the lu.Exec is done in
      its try phase. This ensures that config update hooks (tries to) run at
      all times when the config is updated.

      Disable cluster init with a reachable IP · 411f8ad0
      Iustin Pop authored
      Make the cluster init fail if the IP to which the cluster name resolved
      is already reachable by the master node. This is not a foolproof
      solution, but it allows a cheap method of detecting simple mistakes.
      
      It will also disallow using the master node name as cluster name (which
      is something good).
      
      The only drawbacks that I see are:
        - you are not allowed to do this, which might come in handy in cluster
          upgrades; but since we support rename, this is mitigated
        - cluster init takes longer now (+the timeout value, set to 5
          seconds), but since this is a one-off operation, it should be ok
