      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.).

      call_instance_start: add optional hv/be parameters · 0eca8e0c
      Iustin Pop authored
      
      
      This patch modifies the rpc.call_instance_start - the master side - to
      take optional hv/be parameters. The noded side is unchanged and
      oblivious to the change.
      
      This will allow implementation of single-user capability and such on
      startup (temporary, as opposed to permanent).

      LUDiagnoseOS: change locking and error handling · a6ab004b
      Iustin Pop authored
      Since the “list OSes” call is exported via RAPI, this can be used pretty
      easily to DOS the master daemon during long jobs.
      
      The implementation of LUDiagnoseOS makes an RPC call to all nodes; we
      lock nodes here in order to prevent node removal.
      
      However, after closer examination, the worst case is:
        - we get the list of nodes from the config
        - another thread removes a node
        - our RPC queries reach the removed node
      
      As this point, if ganeti-noded is stopped or doesn't accept our queries,
      the RPC call will return failed, and in the current implementation all
      OSes will become invalid.
      
      If we change the ‘failed RPC’ handling to ignore such nodes, this allows
      us to both remove locking, and to handle transient RPC failures better
      (not invalidating all OSes).
      
      This patch does both these things, with a single drawback: in gnt-os
      diagnose, the down nodes do not appear at all. I think this is a small
      drawback, and the alternative is to add them with status failed; this
      works (3-line patch), but then the output of “list” and “diagnose” will
      no longer be consistent. As such, my proposal is to not list the nodes.

      Fix verify-disks with broken volume groups · ea9ddc07
      Iustin Pop authored
      When a remote node returns invalid LVM data, we check it, but we don't
      stop and continue with the rest of the checks (which require a valid
      volume group). This raises an internal error and breaks verify disks.
      
      This seems unchanged for a long while, I don't know why it surfaced just
      recently.

      Prevent errors when xenvg is broken cluster verify · 9a198532
      Iustin Pop authored
      When vg_name is not returned at all, we currently abort with an internal
      error. This is because we don't catch KeyError.
      
      This patch adds a custom message for this case, and also adds KeyError
      to the list of catched exceptions, just for safety.
      
      On the other hand, we could also just remove this piece of code since
      it's not used at all the ["dfree"] value.

      A bunch of doc and other small fixes · 949bdabe

      This patch adds a couple of both externally and internally reported

        - 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

        - “gnt-instance reinstall --select-os” has wrong prompt, we only
          accept a number for the OS and not the template name

      Distribute built documentation · 2ab2b9f5
      Iustin Pop authored
      This patch changes the way documentation is built in order to distribute
      the generated output in the 'dist' archive, and thus no longer
      requiring the presence of the docbook/rst toolchains during build time.
      This will lower the requirements for installation and also makes the
      build time insignificant.
      
      First, we remove the docbook2pdf rules and variables, since we no longer
      build this kind of docs. Furthermore, the rst source files are not
      (today) processed via replace_vars_sed, so the whole .in rules for doc/
      go away.
      
      Next, we change the ".sgml|.rst -> replace_vars_sed -> .in -> processor
      -> final file" processing to ".sgml|.rst -> generator -> .in ->
      replace_vars_sed -> final file"; this means we first process the file
      using the formatter, with the @VARIABLE@ entries in it, and save the
      output as .in; this output we distribute, and on the user side, the
      replace_vars_sed will use the new configure flags to transform the
      (almost final .in form) to the final form, without needing the
      toolchain.
      
      In configure.ac we also change from ERROR to WARN for the documentation
      generators, and extra tests in Makefile.am check that the programs have
      been found.
      
      This was tested with distcheck and works as expected.

      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

      Change the watcher to use jobs instead of queries · 6dfcc47b
      Iustin Pop authored
      As per the mailing list discussion, this patch changes the watcher to
      use a single job (two opcodes) for getting the cluster state (node list
      and instance list); it will then compute the needed actions based on
      this data.
      
      The patch also archives this job and the verify-disks job.
