      Create runtime dir in bootstrap · 9dae41ad
      Guido Trotter authored
      Some hypervisors (KVM) need RUN_GANETI_DIR to exist even at cluster init
      time. This patch creates it in InitCluster just before hv parameter
      checking. Since the code to make list of directories is already repeated
      twice in the code, and this would be the third time, we abstract it into
      an utils.EnsureDirs function and we call that one from ganti-noded,
      ganeti-masterd and bootstrap.

      99% of the epydoc return tags are "@return:", but each of the modified files
      had one "@returns:" line. We fix this for consistency.

      Instance parameters: force typing · a5728081
      Guido Trotter authored
      We want all the hv/be parameters to have a known type, rather than a
      random mix of empty string, boolean values, and None, so we declare the
      type of each variable and we enforce/convert it.
      
      - Add some new constants for enforceable value types
      - Add new constants dicts HVS_PARAMETER_TYPES and BES_PARAMETER_TYPES
        holding not only the valid parameters but also their types
      - Drop the old HVS_PARAMETERS and BES_PARAMETERS constants and calculate
        the values from the type dict
      - Convert all the default parameters to a valid type value
      - Create a new ForceDictType utils function, to check/enforce a dict's
        element value types, with relevant unit tests
      - Drop a few custom functions to check/convert the BE param types in
        utils and cli, in favor of ForceDictType
      - Double-check the parameter types using ForceDictType in both scripts
        and LogicalUnits, when possible.
      
      As a bonus:
      - Remove some old commented-out code in gnt-instance
      - Remove some already fixed FIXME
      - Fix a bug which prevented VALUE_DEFAULT to be applied to BE parameters
        in SetInstanceParams because the value was checked for validity before
        that transformation was made
      - Fix a bug which prevented initing a cluster and passing hvparams to
        work at all
      - ForceDictType allows an allowed_values for exceptions, which makes us
        able to do the checking even when some values must not be
        converted/typechecked (for example the 'default' string in
        SetInstanceParameters)

      Add a ‘drained’ attribute to node objects · af64c0ea
      Iustin Pop authored
      This attribute will be used to prevent any allocation on the node (any
      of replace-disks with new secondary this node, failover to the node,
      migration to the node).
      
      The patch adds the attribute and initializes it correctly in cluster
      init and for new nodes.

      Add a new node parameter 'offline' · fc0fe88c
      Iustin Pop authored
      This patch adds a new node parameter called offline that will be used to
      mark nodes which should be touched by commands.
      
      We also add this flag at cluster init, node add, and export it to
      iallocator scripts.

      Convert rpc results to a custom type · 781de953
      Iustin Pop authored
      For a long time we had the problem that both RPC-layer errors and
      results from the remote node share the same "valuespace". This is
      because we shouldn't raise an exception when only one node failed
      (and lose the results from the other nodes).
      
      This patch attempts to address this problem by returning a special
      object from RPC calls, which separates the rpc-layer status and the
      remote results into different attributes.
      
      All the users of rpc (mainly cmdlib, but also bootstrap and the
      HooksMaster in mcpu) have been converted to this new model. The code has
      changed from, e.g. for boolean return types:
      
        if not self.rpc.call_...
      
      to
      
        result = self.rpc.call_
        if result.failed or not result.data:
           ^ rpc-layer error    |
                                - result payload
      
      While this is slightly more complicated, it will allow cleaner checks in
      the future; right now the code is just a plain port, without
      optimizations.
      
      There's also a "result.Raise()" which raises an OpExecError if the
      rpc-layer had errors.
      
      One side-effect of the patch is that now all return types from the
      rpc.call_ functions are of either RpcResult (single-node) or dicts of
      (node name, RpcResult); previously, some functions were returning
      different object types based on error status.
      
      The code passes burnin (after many retries :).

      Fix master failover · bbe19c17
      Iustin Pop authored
      The ssconf files were not updated by the master failover. We need to
      push them, and since we already have RPC initialized, we can use the
      standard ConfigWriter to do so - this will take care of both the config
      file and the ssconf files.

      Improve the node add operation · 87622829
      Iustin Pop authored
      Currently, the node add operation uses a job to query the node name and
      the bootstrap function directly reads the config file for the cluster
      name.
      
      This patch changes to that both the cluster name and the verification of
      the node is done via queries to the master.
