      check_ident_key_val, handle no_ and - prefixes · 8b46606c
      Guido Trotter authored
      
      
      If an ident member of an IdentKeyVal relationship starts with no_ or -,
      handle it the same way we do for a key. Some unittests are added to
      check that check_ident_key_val behaves as expected.
      
      This patch also changes ForceDictType to, for now, fail on such an
      entry, and the same to happen when creating an instance or modifying its
      nics or disks.
      
      This behavior will be used later on to allow deletion of os entries in
      os parameters.

      Add -H/-B startup parameters to gnt-instance · d04aaa2f
      Iustin Pop authored
      
      
      This patch modifies the start instance script, opcode and logical unit
      to support temporary startup parameters.
      
      Different from 1.2, where only the kernel arguments were supporting
      changes (and thus xen-pvm specific), this version supports changing all
      hypervisor and backend parameters (with appropriate checks).
      
      This is much more flexible, and allows for example:
        - start with different, temporary kernel
        - start with different memory size
      
      Note: in later versions, this should be extended to cover disk
      parameters as well (e.g. start with drbd without flushes, start with
      drbd in async mode, etc.).

      This patch adds a couple of both externally and internally reported

        - missing SGML tags (Issue 54), report and patch by superdupont
        - wrong variable used in the init.d script, report and patch by
          Karsten Keil <karsten-keil@t-online.de>
        - man page for gnt-instance reinstall needs clarification (Issue 56)
        - gnt-instance man page missing --disks documentation for
          replace-disks
        - gnt-node modify help output is unclear about the -C/-D/-O input
          format, and the man page doesn't document this command at all
        - “gnt-node modify -C yes” for offline or drained nodes had wrong
          error message
        - “gnt-instance reinstall --select-os” has wrong prompt, we only
          accept a number for the OS and not the template name

      Disable synchronous (locking) queries · 77921a95
      Iustin Pop authored
      This patch raises an error in the master daemon in case the user
      requests a locking query; accordingly, all clients were modified to send
      only lockless queries. This is short-term fix, for proper fix the
      clients should be modified to submit a job when the user request a
      locking query.
      
      The other approach would be to ignore the flag passed by the client;
      this would be worse as client's wouldn't get at least an error.
      
      The possible impact of this is multiple:
        - some commands could have been not converted, and thus fail; this
          can be remedied easily
        - the consistency of commands is lost; e.g. node failover will not
          lock the node *while we get the node info*, so we could miss some
          data; this is again in the thread of atomic operations which are
          missing in the current model of query-and-act from gnt-* scripts

      Remove the extra_args parameter in instance start · 07813a9e
      Iustin Pop authored
      This patch removes the extra_args parameter and instead switches the
      instance to the HV_KERNEL_ARGS hypervisor option.
      
      This is a big change, but it's a needed cleanup, this extra parameter on
      all RPC calls is not generic and we also need to have a persistent value
      here.

      gnt-instance info: remove hvattr descriptions · dfff41f8
      Guido Trotter authored
      Having hvattr descriptions is only confusing for the user, because even
      if they explain better what an attribute is about, they don't help in
      deciding what keyword should be used to actually set it. If in the
      future we want descriptions they should probably live in constants.py,
      and be displayed together with the key, rather than instead of it.
      
      This patch also changes the handling of the vnc console connection
      description, making compatible work with both kvm and xen-hvm.

      Some batcher fixes · 4082e6f9
      Iustin Pop authored
      Currently the batcher hypervisor parameter must be a dict with one
      element (e.g. {"xen-hvm": { "acpi": true }}). This is overly complex and
      hard to validate correctly; the patch splits it in two:
        - one "hypervisor" string parameter, with the name of the hypervisor
        - one "hvparams" dictionary, with the hypervisor parameters
      
      The patch also changes the error handling in parsing the definition file
      - since this is not a long-running file, we are less concerned with safe
      closing of the file, and more with presenting meaningful error
      messages.

      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 new instance query flag ‘disk_usage’ · 024e157f
      Iustin Pop authored
      This patch adds a new instance query flag called disk_usage that
      retrieves the overall space used by an instance on each of its nodes.
      This can be used when balancing the cluster or checking N+1 status.
      
      The flag is also exported in RAPI. Note the flag is currently broken for
      file-based instances, as it represents the amount of space in the
      cluster volume group.

      Implement lockless query operations · ec79568d
      Iustin Pop authored
      This patch adds the framework for, and enables lockless OpQueryInstances. This
      means that instances will be shown in ERROR_up or ERROR_down state, even though
      this is not an error (but just an in-progress job).
      
      The framework is implemented as follows:
        - the OpQueryInstances, OpQueryNodes and OpQueryExports opcodes take
          an additional “use_locking” flag which will denote whether to lock
          or not; this patch only implements this for LUQueryInstances
        - the luxi query functions take an additional argument use_locking
          which is passed to the master daemon, and then passed to the above
          opcodes
        - cli.py export a new SYNC_OPT command line options which implement
          setting this flag to true
        - except for gnt-instance list, which uses this option, and for
          name-only queries (e.g. QueryNodes(fields=["names"])), all other
          callers are setting this flag to True
        - RAPI also sets the flag to True
      
      The patch was tested with a continuous (0.2s sleep in-between)
      gnt-instance list during a burnin, and no problems were observed.
