  with 3 possible values -- ``up``, ``down`` and ``offline``.
12 735e1318 Michael Hanselmann
- Replaced ``--disks`` option of ``gnt-instance replace-disks`` with a
13 735e1318 Michael Hanselmann

14 735e1318 Michael Hanselmann
  upon recreation.
15 09037780 Michael Hanselmann
- Removed deprecated ``QueryLocks`` LUXI request. Use
16 09037780 Michael Hanselmann

Incompatible/important changes and bugfixes
25 42539276 Michael Hanselmann
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
26 896a03f6 Iustin Pop
27 88bc199a Michael Hanselmann
- The default of the ``/2/instances/[instance_name]/rename`` RAPI
28 88bc199a Michael Hanselmann
  resource's ``ip_check`` parameter changed from ``True`` to ``False``
29 42539276 Michael Hanselmann
  to match the underlying LUXI interface.
30 de40437a Michael Hanselmann
- The ``/2/nodes/[node_name]/evacuate`` RAPI resource was changed to use
31 de40437a Michael Hanselmann
  body parameters, see :doc:`RAPI documentation <rapi>`. The server does
32 de40437a Michael Hanselmann
  not maintain backwards-compatibility as the underlying operation
33 de40437a Michael Hanselmann
  changed in an incompatible way. The RAPI client can talk to old
34 de40437a Michael Hanselmann
  servers, but it needs to be told so as the return value changed.
35 526a662a Michael Hanselmann
- When creating file-based instances via RAPI, the ``file_driver``
36 42539276 Michael Hanselmann
  parameter no longer defaults to ``loop`` and must be specified.
37 42539276 Michael Hanselmann
- The deprecated ``bridge`` NIC parameter is no longer supported. Use
38 42539276 Michael Hanselmann
  ``link`` instead.
39 3fd7f652 Michael Hanselmann
- Support for the undocumented and deprecated RAPI instance creation
40 3fd7f652 Michael Hanselmann
  request format version 0 has been dropped. Use version 1, supported
41 3fd7f652 Michael Hanselmann
  since Ganeti 2.1.3 and :doc:`documented <rapi>`, instead.
42 7578ab0a Michael Hanselmann
- Pyparsing 1.4.6 or above is required, see :doc:`installation
43 42539276 Michael Hanselmann
  documentation <install>`.
44 56372573 Guido Trotter
- The "cluster-verify" hooks are now executed per group by the
45 42539276 Michael Hanselmann
  ``OP_CLUSTER_VERIFY_GROUP`` opcode. This maintains the same behavior
46 42539276 Michael Hanselmann
  if you just run ``gnt-cluster verify``, which generates one opcode per
47 42539276 Michael Hanselmann
  group.
48 896a03f6 Iustin Pop
- The environment as passed to the OS scripts is cleared, and thus no
49 896a03f6 Iustin Pop
  environment variables defined in the node daemon's environment will be
50 42539276 Michael Hanselmann
  inherited by the scripts.
51 42539276 Michael Hanselmann
- The :doc:`iallocator <iallocator>` mode ``multi-evacuate`` has been
52 42539276 Michael Hanselmann
  deprecated.
53 42539276 Michael Hanselmann
- :doc:`New iallocator modes <design-multi-reloc>` have been added to
54 42539276 Michael Hanselmann
  support operations involving multiple node groups.
55 42539276 Michael Hanselmann
- Offline nodes are ignored when failing over an instance.
56 7cbdc2a2 Michael Hanselmann
- Support for KVM version 1.0, which changed the version reporting format
57 7cbdc2a2 Michael Hanselmann
  from 3 to 2 digits.
58 7cbdc2a2 Michael Hanselmann
- Includes all bugfixes made in the 2.4 series
59 42539276 Michael Hanselmann

91 42539276 Michael Hanselmann
- When given an explicit job ID, ``gnt-job info`` will work for archived
92 42539276 Michael Hanselmann
  jobs.
93 42539276 Michael Hanselmann
- Jobs can define dependencies on other jobs (not yet supported via
94 42539276 Michael Hanselmann
  RAPI or command line, but used by internal commands and usable via
95 42539276 Michael Hanselmann
  LUXI).
96 42539276 Michael Hanselmann
97 42539276 Michael Hanselmann
  - Lock monitor (``gnt-debug locks``) shows jobs waiting for

~~~~~~~~~~~~~~~~~~~~~~~
110 42539276 Michael Hanselmann
111 42539276 Michael Hanselmann

  request
243 e20832af Renรฉ Nussbaumer

  relative path, the documentation was right
251 6e1156ff Iustin Pop

*(Released Thu, 12 May 2011)*
273 1bbf0c40 Iustin Pop
274 1bbf0c40 Iustin Pop
Many bug-fixes and a few new small features:

280 1bbf0c40 Iustin Pop
- Many fixes related to the ``cluster-merge`` tool
281 1bbf0c40 Iustin Pop
- Fixed a race condition in the lock monitor, which caused failures
282 1bbf0c40 Iustin Pop
  during (at least) creation of many instances in parallel
283 1bbf0c40 Iustin Pop
- Improved output for gnt-job info
284 1bbf0c40 Iustin Pop

289 1bbf0c40 Iustin Pop
  (e.g. DRBD replace-disks) other jobs do not enter 'blocking acquire'
290 1bbf0c40 Iustin Pop
  too early and thus prevent the use of the 'fair' mechanism
291 1bbf0c40 Iustin Pop
- Changed instance query data (``gnt-instance info``) to not acquire
292 1bbf0c40 Iustin Pop
  locks unless needed, thus allowing its use on locked instance if only
293 1bbf0c40 Iustin Pop
  static information is asked for
294 1bbf0c40 Iustin Pop
- Improved behaviour with filesystems that do not support rename on an
295 1bbf0c40 Iustin Pop
  opened file
296 1bbf0c40 Iustin Pop
- Fixed the behaviour of ``prealloc_wipe_disks`` cluster parameter which
297 1bbf0c40 Iustin Pop
  kept locks on all nodes during the wipe, which is unneeded
298 1bbf0c40 Iustin Pop
- Fixed ``gnt-watcher`` handling of errors during hooks execution
299 1bbf0c40 Iustin Pop
- Fixed bug in ``prealloc_wipe_disks`` with small disk sizes (less than
300 1bbf0c40 Iustin Pop
  10GiB) which caused the wipe to fail right at the end in some cases
301 1bbf0c40 Iustin Pop
- Fixed master IP activation when doing master failover with no-voting
302 1bbf0c40 Iustin Pop
- Fixed bug in ``gnt-node add --readd`` which allowed the re-adding of
303 1bbf0c40 Iustin Pop
  the master node itself
304 1bbf0c40 Iustin Pop
- Fixed potential data-loss in under disk full conditions, where Ganeti
305 1bbf0c40 Iustin Pop
  wouldn't check correctly the return code and would consider
306 1bbf0c40 Iustin Pop
  partially-written files 'correct'
307 1bbf0c40 Iustin Pop
- Fixed bug related to multiple VGs and DRBD disk replacing
308 1bbf0c40 Iustin Pop
- Added new disk parameter ``metavg`` that allows placement of the meta
309 1bbf0c40 Iustin Pop
  device for DRBD in a different volume group
310 1bbf0c40 Iustin Pop
- Fixed error handling in the node daemon when the system libc doesn't
311 1bbf0c40 Iustin Pop
  have major number 6 (i.e. if ``libc.so.6`` is not the actual libc)
312 1bbf0c40 Iustin Pop
- Fixed lock release during replace-disks, which kept cluster-wide locks
313 1bbf0c40 Iustin Pop
  when doing disk replaces with an iallocator script
314 1bbf0c40 Iustin Pop
- Added check for missing bridges in cluster verify
315 1bbf0c40 Iustin Pop
- Handle EPIPE errors while writing to the terminal better, so that
316 1bbf0c40 Iustin Pop
  piping the output to e.g. ``less`` doesn't cause a backtrace
317 1bbf0c40 Iustin Pop
- Fixed rare case where a ^C during Luxi calls could have been
318 1bbf0c40 Iustin Pop
  interpreted as server errors, instead of simply terminating
319 1bbf0c40 Iustin Pop
- Fixed a race condition in LUGroupAssignNodes (``gnt-group
320 1bbf0c40 Iustin Pop
  assign-nodes``)
321 1bbf0c40 Iustin Pop
- Added a few more parameters to the KVM hypervisor, allowing a second
322 1bbf0c40 Iustin Pop
  CDROM, custom disk type for CDROMs and a floppy image
323 1bbf0c40 Iustin Pop
- Removed redundant message in instance rename when the name is given
324 1bbf0c40 Iustin Pop
  already as a FQDN
325 1bbf0c40 Iustin Pop
- Added option to ``gnt-instance recreate-disks`` to allow creating the
326 1bbf0c40 Iustin Pop
  disks on new nodes, allowing recreation when the original instance
327 1bbf0c40 Iustin Pop
  nodes are completely gone
328 1bbf0c40 Iustin Pop
- Added option when converting disk templates to DRBD to skip waiting
329 1bbf0c40 Iustin Pop
  for the resync, in order to make the instance available sooner
330 1bbf0c40 Iustin Pop
- Added two new variables to the OS scripts environment (containing the
331 1bbf0c40 Iustin Pop
  instance's nodes)
332 1bbf0c40 Iustin Pop
- Made the root_path and optional parameter for the xen-pvm hypervisor,
333 1bbf0c40 Iustin Pop
  to allow use of ``pvgrub`` as bootloader
334 b92a2f3e Iustin Pop
- Changed the instance memory modifications to only check out-of-memory
335 b92a2f3e Iustin Pop
  conditions on memory increases, and turned the secondary node warnings
336 b92a2f3e Iustin Pop
  into errors (they can still be overridden via ``--force``)
337 f01738fc Iustin Pop
- Fixed the handling of a corner case when the Python installation gets
338 f01738fc Iustin Pop
  corrupted (e.g. a bad disk) while ganeti-noded is running and we try
339 f01738fc Iustin Pop
  to execute a command that doesn't exist
340 bb851c63 Iustin Pop
- Fixed a bug in ``gnt-instance move`` (LUInstanceMove) when the primary
341 bb851c63 Iustin Pop
  node of the instance returned failures during instance shutdown; this
342 bb851c63 Iustin Pop
  adds the option ``--ignore-consistency`` to gnt-instance move
343 1bbf0c40 Iustin Pop
344 1bbf0c40 Iustin Pop
And as usual, various improvements to the error messages, documentation
345 1bbf0c40 Iustin Pop
and man pages.

353 c199dbae Iustin Pop
Emergency bug-fix release. ``tools/cfgupgrade`` was broken and overwrote

*(Released Mon, 28 Feb 2011)*
376 94b697b0 Iustin Pop
377 94b697b0 Iustin Pop
A critical fix for the ``prealloc_wipe_disks`` feature: it is possible
378 94b697b0 Iustin Pop
that this feature wiped the disks of the wrong instance, leading to loss
379 94b697b0 Iustin Pop
of data.
380 94b697b0 Iustin Pop
381 94b697b0 Iustin Pop
Other changes:
382 94b697b0 Iustin Pop
383 df3df936 Michael Hanselmann

*(Released Mon, 21 Feb 2011)*
392 e41a1c0c Iustin Pop
393 e41a1c0c Iustin Pop
A number of bug fixes plus just a couple functionality changes.
394 e41a1c0c Iustin Pop
395 e41a1c0c Iustin Pop
On the user-visible side, the ``gnt-* list`` command output has changed
396 df3df936 Michael Hanselmann
with respect to "special" field states. The current rc1 style of display
397 df3df936 Michael Hanselmann
can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in
398 df3df936 Michael Hanselmann
the default output mode special fields states are displayed as follows:
399 e41a1c0c Iustin Pop
400 df3df936 Michael Hanselmann
- Offline resource: ``*``
401 df3df936 Michael Hanselmann
- Unavailable/not applicable: ``-``
402 df3df936 Michael Hanselmann
- Data missing (RPC failure): ``?``
403 df3df936 Michael Hanselmann
- Unknown field: ``??``
404 e41a1c0c Iustin Pop
405 e41a1c0c Iustin Pop
Another user-visible change is the addition of ``--force-join`` to
406 e41a1c0c Iustin Pop
``gnt-node add``.
407 e41a1c0c Iustin Pop
408 e41a1c0c Iustin Pop
As for bug fixes:
409 e41a1c0c Iustin Pop
410 e41a1c0c Iustin Pop
- ``tools/cluster-merge`` has seen many fixes and is now enabled again
411 df3df936 Michael Hanselmann
- Fixed regression in RAPI/instance reinstall where all parameters were
412 e41a1c0c Iustin Pop
  required (instead of optional)
413 df3df936 Michael Hanselmann
- Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2
414 df3df936 Michael Hanselmann
- Fixed iallocator usage (offline nodes were not considered offline)
415 df3df936 Michael Hanselmann
- Fixed ``gnt-node list`` with respect to non-vm_capable nodes
416 df3df936 Michael Hanselmann
- Fixed hypervisor and OS parameter validation with respect to
417 e41a1c0c Iustin Pop
  non-vm_capable nodes
418 df3df936 Michael Hanselmann
- Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly
419 e41a1c0c Iustin Pop
  cosmetic)
420 df3df936 Michael Hanselmann
- Fixed ``tools/listrunner`` with respect to agent-based usage

*(Released Fri,  4 Feb 2011)*
427 ec31a18f Iustin Pop
428 ec31a18f Iustin Pop
Many changes and fixes since the beta1 release. While there were some
429 ec31a18f Iustin Pop
internal changes, the code has been mostly stabilised for the RC
430 ec31a18f Iustin Pop
release.
431 ec31a18f Iustin Pop
432 ec31a18f Iustin Pop
Note: the dumb allocator was removed in this release, as it was not kept
433 ec31a18f Iustin Pop
up-to-date with the IAllocator protocol changes. It is recommended to
434 ec31a18f Iustin Pop
use the ``hail`` command from the ganeti-htools package.
435 ec31a18f Iustin Pop
436 ec31a18f Iustin Pop
Note: the 2.4 and up versions of Ganeti are not compatible with the
437 ec31a18f Iustin Pop
0.2.x branch of ganeti-htools. You need to upgrade to
438 ec31a18f Iustin Pop
ganeti-htools-0.3.0 (or later).
439 ec31a18f Iustin Pop
440 ec31a18f Iustin Pop
Regressions fixed from 2.3
441 ec31a18f Iustin Pop
~~~~~~~~~~~~~~~~~~~~~~~~~~
442 ec31a18f Iustin Pop
443 ec31a18f Iustin Pop
- Fixed the ``gnt-cluster verify-disks`` command
444 ec31a18f Iustin Pop
- Made ``gnt-cluster verify-disks`` work in parallel (as opposed to
445 ec31a18f Iustin Pop
  serially on nodes)
446 ec31a18f Iustin Pop
- Fixed disk adoption breakage
447 ec31a18f Iustin Pop
- Fixed wrong headers in instance listing for field aliases
448 ec31a18f Iustin Pop
449 ec31a18f Iustin Pop
Other bugs fixed
450 ec31a18f Iustin Pop
~~~~~~~~~~~~~~~~
451 ec31a18f Iustin Pop
452 ec31a18f Iustin Pop
- Fixed corner case in KVM handling of NICs
453 ec31a18f Iustin Pop
- Fixed many cases of wrong handling of non-vm_capable nodes
454 ec31a18f Iustin Pop
- Fixed a bug where a missing instance symlink was not possible to
455 ec31a18f Iustin Pop
  recreate with any ``gnt-*`` command (now ``gnt-instance
456 ec31a18f Iustin Pop
  activate-disks`` does it)
457 ec31a18f Iustin Pop
- Fixed the volume group name as reported by ``gnt-cluster
458 ec31a18f Iustin Pop
  verify-disks``
459 ec31a18f Iustin Pop
- Increased timeouts for the import-export code, hopefully leading to
460 ec31a18f Iustin Pop
  fewer aborts due network or instance timeouts
461 ec31a18f Iustin Pop
- Fixed bug in ``gnt-node list-storage``
462 ec31a18f Iustin Pop
- Fixed bug where not all daemons were started on cluster
463 ec31a18f Iustin Pop
  initialisation, but only at the first watcher run
464 ec31a18f Iustin Pop
- Fixed many bugs in the OOB implementation
465 ec31a18f Iustin Pop
- Fixed watcher behaviour in presence of instances with offline
466 ec31a18f Iustin Pop
  secondaries
467 ec31a18f Iustin Pop
- Fixed instance list output for instances running on the wrong node
468 ec31a18f Iustin Pop
- a few fixes to the cluster-merge tool, but it still cannot merge
469 ec31a18f Iustin Pop
  multi-node groups (currently it is not recommended to use this tool)
470 ec31a18f Iustin Pop
471 ec31a18f Iustin Pop
472 ec31a18f Iustin Pop
Improvements
473 ec31a18f Iustin Pop
~~~~~~~~~~~~
474 ec31a18f Iustin Pop
475 ec31a18f Iustin Pop
- Improved network configuration for the KVM hypervisor
476 ec31a18f Iustin Pop
- Added e1000 as a supported NIC for Xen-HVM
477 ec31a18f Iustin Pop
- Improved the lvmstrap tool to also be able to use partitions, as
478 ec31a18f Iustin Pop
  opposed to full disks
479 ec31a18f Iustin Pop
- Improved speed of disk wiping (the cluster parameter
480 ec31a18f Iustin Pop
  ``prealloc_wipe_disks``, so that it has a low impact on the total time
481 ec31a18f Iustin Pop
  of instance creations
482 ec31a18f Iustin Pop
- Added documentation for the OS parameters
483 ec31a18f Iustin Pop
- Changed ``gnt-instance deactivate-disks`` so that it can work if the
484 ec31a18f Iustin Pop
  hypervisor is not responding
485 ec31a18f Iustin Pop
- Added display of blacklisted and hidden OS information in
486 ec31a18f Iustin Pop
  ``gnt-cluster info``
487 ec31a18f Iustin Pop
- Extended ``gnt-cluster verify`` to also validate hypervisor, backend,
488 ec31a18f Iustin Pop
  NIC and node parameters, which might create problems with currently
489 ec31a18f Iustin Pop
  invalid (but undetected) configuration files, but prevents validation
490 ec31a18f Iustin Pop
  failures when unrelated parameters are modified
491 ec31a18f Iustin Pop
- Changed cluster initialisation to wait for the master daemon to become
492 ec31a18f Iustin Pop
  available
493 ec31a18f Iustin Pop
- Expanded the RAPI interface:
494 ec31a18f Iustin Pop
495 ec31a18f Iustin Pop
  - Added config redistribution resource
496 ec31a18f Iustin Pop
  - Added activation/deactivation of instance disks
497 ec31a18f Iustin Pop
  - Added export of console information
498 ec31a18f Iustin Pop
499 ec31a18f Iustin Pop
- Implemented log file reopening on SIGHUP, which allows using
500 ec31a18f Iustin Pop
  logrotate(8) for the Ganeti log files
501 ec31a18f Iustin Pop
- Added a basic OOB helper script as an example
502 ec31a18f Iustin Pop

516 3daa24ea Michael Hanselmann
  document <design-oob>`
517 3daa24ea Michael Hanselmann
- Removed support for roman numbers from ``gnt-node list`` and
518 3daa24ea Michael Hanselmann
  ``gnt-instance list``.
519 3daa24ea Michael Hanselmann
- Allowed modification of master network interface via ``gnt-cluster
520 3daa24ea Michael Hanselmann
  modify --master-netdev``
521 3daa24ea Michael Hanselmann
- Accept offline secondaries while shutting down instance disks
522 3daa24ea Michael Hanselmann
- Added ``blockdev_prefix`` parameter to Xen PVM and HVM hypervisors
523 3daa24ea Michael Hanselmann
- Added support for multiple LVM volume groups
524 3daa24ea Michael Hanselmann
- Avoid sorting nodes for ``gnt-node list`` if specific nodes are
525 3daa24ea Michael Hanselmann
  requested
526 3daa24ea Michael Hanselmann
- Added commands to list available fields:
527 3daa24ea Michael Hanselmann
528 3daa24ea Michael Hanselmann
  - ``gnt-node list-fields``
529 3daa24ea Michael Hanselmann
  - ``gnt-group list-fields``
530 3daa24ea Michael Hanselmann
  - ``gnt-instance list-fields``
531 3daa24ea Michael Hanselmann

Integration
535 3daa24ea Michael Hanselmann
~~~~~~~~~~~
536 3daa24ea Michael Hanselmann
537 fdd9ac5b Michael Hanselmann
- Moved ``rapi_users`` file into separate directory, now named
538 df3df936 Michael Hanselmann
  ``.../ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a
539 3daa24ea Michael Hanselmann
  symlink
540 3daa24ea Michael Hanselmann
- Added new tool for running commands on many machines,
541 3daa24ea Michael Hanselmann
  ``tools/ganeti-listrunner``
542 cc0dec7b Iustin Pop
- Implemented more verbose result in ``OpInstanceConsole`` opcode, also
543 3daa24ea Michael Hanselmann
  improving the ``gnt-instance console`` output
544 3daa24ea Michael Hanselmann
- Allowed customisation of disk index separator at ``configure`` time
545 3daa24ea Michael Hanselmann
- Export node group allocation policy to :doc:`iallocator <iallocator>`

548 3daa24ea Michael Hanselmann
- Split ``utils`` module into smaller parts
549 d7a08491 Michael Hanselmann
- Changed query operations to return more detailed information, e.g.
550 d7a08491 Michael Hanselmann
  whether an information is unavailable due to an offline node. To use
551 d7a08491 Michael Hanselmann
  this new functionality, the LUXI call ``Query`` must be used. Field
552 d7a08491 Michael Hanselmann
  information is now stored by the master daemon and can be retrieved
553 3daa24ea Michael Hanselmann
  using ``QueryFields``. Instances, nodes and groups can also be queried
554 3daa24ea Michael Hanselmann
  using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet
555 3daa24ea Michael Hanselmann
  exposed via RAPI). The following commands make use of this
556 3daa24ea Michael Hanselmann
  infrastructure change:
557 3daa24ea Michael Hanselmann
558 3daa24ea Michael Hanselmann
  - ``gnt-group list``

581 3daa24ea Michael Hanselmann
  - Implemented ``no_install`` for instance creation
582 3daa24ea Michael Hanselmann
  - Implemented OS parameters for instance reinstallation, allowing
583 3daa24ea Michael Hanselmann
    use of special settings on reinstallation (e.g. for preserving data)

782 529a8d17 Iustin Pop
Version 2.2.0 rc0
783 529a8d17 Iustin Pop
-----------------
784 529a8d17 Iustin Pop
785 41c44dcf Iustin Pop
*(Released Fri, 30 Jul 2010)*
786 529a8d17 Iustin Pop
787 529a8d17 Iustin Pop
Important change: the internal RPC mechanism between Ganeti nodes has
788 529a8d17 Iustin Pop
changed from using a home-grown http library (based on the Python base
789 529a8d17 Iustin Pop
libraries) to use the PycURL library. This requires that PycURL is
790 529a8d17 Iustin Pop
installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
791 529a8d17 Iustin Pop
against GnuTLS by default. cURL's support for GnuTLS had known issues
792 529a8d17 Iustin Pop
before cURL 7.21.0 and we recommend using the latest cURL release or
793 529a8d17 Iustin Pop
linking against OpenSSL. Most other distributions already link PycURL
794 529a8d17 Iustin Pop
and cURL against OpenSSL. The command::
795 529a8d17 Iustin Pop
796 529a8d17 Iustin Pop
  python -c 'import pycurl; print pycurl.version'
797 529a8d17 Iustin Pop
798 529a8d17 Iustin Pop
can be used to determine the libraries PycURL and cURL are linked
799 529a8d17 Iustin Pop
against.
800 529a8d17 Iustin Pop
801 529a8d17 Iustin Pop
Other significant changes:
802 529a8d17 Iustin Pop
803 529a8d17 Iustin Pop
- Rewrote much of the internals of the job queue, in order to achieve
804 529a8d17 Iustin Pop
  better parallelism; this decouples job query operations from the job
805 529a8d17 Iustin Pop
  processing, and it should allow much nicer behaviour of the master
806 529a8d17 Iustin Pop
  daemon under load, and it also has uncovered some long-standing bugs
807 529a8d17 Iustin Pop
  related to the job serialisation (now fixed)
808 529a8d17 Iustin Pop
- Added a default iallocator setting to the cluster parameters,
809 529a8d17 Iustin Pop
  eliminating the need to always pass nodes or an iallocator for
810 529a8d17 Iustin Pop
  operations that require selection of new node(s)
811 529a8d17 Iustin Pop
- Added experimental support for the LXC virtualization method
812 529a8d17 Iustin Pop
- Added support for OS parameters, which allows the installation of
813 529a8d17 Iustin Pop
  instances to pass parameter to OS scripts in order to customise the
814 529a8d17 Iustin Pop
  instance
815 529a8d17 Iustin Pop
- Added a hypervisor parameter controlling the migration type (live or
816 529a8d17 Iustin Pop
  non-live), since hypervisors have various levels of reliability; this
817 529a8d17 Iustin Pop
  has renamed the 'live' parameter to 'mode'
818 529a8d17 Iustin Pop
- Added a cluster parameter ``reserved_lvs`` that denotes reserved
819 529a8d17 Iustin Pop
  logical volumes, meaning that cluster verify will ignore them and not
820 529a8d17 Iustin Pop
  flag their presence as errors
821 529a8d17 Iustin Pop
- The watcher will now reset the error count for failed instances after
822 529a8d17 Iustin Pop
  8 hours, thus allowing self-healing if the problem that caused the
823 529a8d17 Iustin Pop
  instances to be down/fail to start has cleared in the meantime
824 529a8d17 Iustin Pop
- Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
825 529a8d17 Iustin Pop
  check for, and warn, if the drbd module parameter ``usermode_helper``
826 529a8d17 Iustin Pop
  is not consistent with the cluster-wide setting; this is needed to
827 529a8d17 Iustin Pop
  make diagnose easier of failed drbd creations
828 529a8d17 Iustin Pop
- Started adding base IPv6 support, but this is not yet
829 529a8d17 Iustin Pop
  enabled/available for use
830 529a8d17 Iustin Pop
- Rename operations (cluster, instance) will now return the new name,
831 529a8d17 Iustin Pop
  which is especially useful if a short name was passed in
832 529a8d17 Iustin Pop
- Added support for instance migration in RAPI
833 529a8d17 Iustin Pop
- Added a tool to pre-configure nodes for the SSH setup, before joining
834 529a8d17 Iustin Pop
  them to the cluster; this will allow in the future a simplified model
835 529a8d17 Iustin Pop
  for node joining (but not yet fully enabled in 2.2); this needs the
836 529a8d17 Iustin Pop
  paramiko python library
837 529a8d17 Iustin Pop
- Fixed handling of name-resolving errors
838 529a8d17 Iustin Pop
- Fixed consistency of job results on the error path
839 529a8d17 Iustin Pop
- Fixed master-failover race condition when executed multiple times in
840 529a8d17 Iustin Pop
  sequence
841 529a8d17 Iustin Pop
- Fixed many bugs related to the job queue (mostly introduced during the
842 529a8d17 Iustin Pop
  2.2 development cycle, so not all are impacting 2.1)
843 529a8d17 Iustin Pop
- Fixed instance migration with missing disk symlinks
844 529a8d17 Iustin Pop
- Fixed handling of unknown jobs in ``gnt-job archive``
845 529a8d17 Iustin Pop
- And many other small fixes/improvements
846 529a8d17 Iustin Pop
847 529a8d17 Iustin Pop
Internal changes:
848 529a8d17 Iustin Pop
849 529a8d17 Iustin Pop
- Enhanced both the unittest and the QA coverage
850 529a8d17 Iustin Pop
- Switched the opcode validation to a generic model, and extended the
851 529a8d17 Iustin Pop
  validation to all opcode parameters
852 529a8d17 Iustin Pop
- Changed more parts of the code that write shell scripts to use the
853 529a8d17 Iustin Pop
  same class for this
854 529a8d17 Iustin Pop
- Switched the master daemon to use the asyncore library for the Luxi
855 529a8d17 Iustin Pop
  server endpoint

866 e0897adf Michael Hanselmann
- Added per-request RPC timeout
867 ab221ddf Michael Hanselmann
- RAPI now requires a Content-Type header for requests with a body (e.g.
868 ab221ddf Michael Hanselmann
  ``PUT`` or ``POST``) which must be set to ``application/json`` (see
869 a4978169 Michael Hanselmann
  :rfc:`2616` (HTTP/1.1), section 7.2.1)
870 e0897adf Michael Hanselmann
- ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
871 e0897adf Michael Hanselmann
  reachable
872 e0897adf Michael Hanselmann
- Implemented initial support for running Ganeti daemons as separate
873 e0897adf Michael Hanselmann

  ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
875 e0897adf Michael Hanselmann
  time)
876 e0897adf Michael Hanselmann

  key (instead of 1024 bit)
880 e0897adf Michael Hanselmann
- Added new cluster configuration file for cluster domain secret
881 e0897adf Michael Hanselmann

Bugfixes only:
924 ae828011 Guido Trotter
  - Add an option to only select some reboot types during qa/burnin.
925 ae828011 Guido Trotter
    (on some hypervisors consequent reboots are not supported)
926 ae828011 Guido Trotter
  - Fix infrequent race condition in master failover. Sometimes the old
927 ae828011 Guido Trotter
    master ip address would be still detected as up for a short time
928 ae828011 Guido Trotter
    after it was removed, causing failover to fail.
929 ae828011 Guido Trotter
  - Decrease mlockall warnings when the ctypes module is missing. On
930 ae828011 Guido Trotter
    Python 2.4 we support running even if no ctypes module is installed,
931 ae828011 Guido Trotter
    but we were too verbose about this issue.
932 ae828011 Guido Trotter
  - Fix building on old distributions, on which man doesn't have a
933 ae828011 Guido Trotter
    --warnings option.
934 ae828011 Guido Trotter
  - Fix RAPI not to ignore the MAC address on instance creation
935 ae828011 Guido Trotter
  - Implement the old instance creation format in the RAPI client.

984 14d91053 Guido Trotter
A medium sized development cycle. Some new features, and some
985 14d91053 Guido Trotter
fixes/small improvements/cleanups.
986 14d91053 Guido Trotter
987 14d91053 Guido Trotter
Significant features
988 14d91053 Guido Trotter
~~~~~~~~~~~~~~~~~~~~
989 14d91053 Guido Trotter
990 14d91053 Guido Trotter
The node deamon now tries to mlock itself into memory, unless the
991 14d91053 Guido Trotter
``--no-mlock`` flag is passed. It also doesn't fail if it can't write
992 14d91053 Guido Trotter
its logs, and falls back to console logging. This allows emergency
993 14d91053 Guido Trotter
features such as ``gnt-node powercycle`` to work even in the event of a
994 14d91053 Guido Trotter
broken node disk (tested offlining the disk hosting the node's
995 722702e3 Guido Trotter
filesystem and dropping its memory caches; don't try this at home)
996 14d91053 Guido Trotter
997 14d91053 Guido Trotter
KVM: add vhost-net acceleration support. It can be tested with a new
998 14d91053 Guido Trotter
enough version of the kernel and of qemu-kvm.
999 14d91053 Guido Trotter
1000 14d91053 Guido Trotter
KVM: Add instance chrooting feature. If you use privilege dropping for
1001 14d91053 Guido Trotter
your VMs you can also now force them to chroot to an empty directory,
1002 14d91053 Guido Trotter
before starting the emulated guest.
1003 14d91053 Guido Trotter
1004 14d91053 Guido Trotter
KVM: Add maximum migration bandwith and maximum downtime tweaking
1005 14d91053 Guido Trotter
support (requires a new-enough version of qemu-kvm).
1006 14d91053 Guido Trotter
1007 14d91053 Guido Trotter
Cluster verify will now warn if the master node doesn't have the master
1008 14d91053 Guido Trotter
ip configured on it.
1009 14d91053 Guido Trotter
1010 14d91053 Guido Trotter
Add a new (incompatible) instance creation request format to RAPI which
1011 14d91053 Guido Trotter
supports all parameters (previously only a subset was supported, and it
1012 14d91053 Guido Trotter
wasn't possible to extend the old format to accomodate all the new
1013 14d91053 Guido Trotter
features. The old format is still supported, and a client can check for
1014 14d91053 Guido Trotter
this feature, before using it, by checking for its presence in the
1015 14d91053 Guido Trotter
``features`` RAPI resource.
1016 14d91053 Guido Trotter
1017 14d91053 Guido Trotter
Now with ancient latin support. Try it passing the ``--roman`` option to
1018 722702e3 Guido Trotter
``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
1019 722702e3 Guido Trotter
(requires the python-roman module to be installed, in order to work).

Other changes
1022 14d91053 Guido Trotter
~~~~~~~~~~~~~
1023 14d91053 Guido Trotter
1024 14d91053 Guido Trotter
As usual many internal code refactorings, documentation updates, and
1025 14d91053 Guido Trotter
such. Among others:
1026 14d91053 Guido Trotter
1027 14d91053 Guido Trotter
  - Lots of improvements and cleanups to the experimental Remote API
1028 14d91053 Guido Trotter
    (RAPI) client library.
1029 14d91053 Guido Trotter
  - A new unit test suite for the core daemon libraries.
1030 14d91053 Guido Trotter
  - A fix to creating missing directories makes sure the umask is not
1031 14d91053 Guido Trotter
    applied anymore. This enforces the same directory permissions
1032 14d91053 Guido Trotter
    everywhere.
1033 14d91053 Guido Trotter
  - Better handling terminating daemons with ctrl+c (used when running
1034 14d91053 Guido Trotter
    them in debugging mode).
1035 14d91053 Guido Trotter
  - Fix a race condition in live migrating a KVM instance, when stat()
1036 14d91053 Guido Trotter
    on the old proc status file returned EINVAL, which is an unexpected
1037 14d91053 Guido Trotter
    value.
1038 1de45c78 Guido Trotter
  - Fixed manpage checking with newer man and utf-8 charachters. But now
1039 1de45c78 Guido Trotter
    you need the en_US.UTF-8 locale enabled to build Ganeti from git.

1054 ba538816 Iustin Pop
1055 ba538816 Iustin Pop
Another release with a long development cycle, during which many
1056 ba538816 Iustin Pop
different features were added.
1057 ba538816 Iustin Pop
1058 ba538816 Iustin Pop
Significant features
1059 ba538816 Iustin Pop
~~~~~~~~~~~~~~~~~~~~
1060 ba538816 Iustin Pop
1061 ba538816 Iustin Pop
The KVM hypervisor now can run the individual instances as non-root, to
1062 ba538816 Iustin Pop
reduce the impact of a VM being hijacked due to bugs in the
1063 ba538816 Iustin Pop
hypervisor. It is possible to run all instances as a single (non-root)
1064 ba538816 Iustin Pop
user, to manually specify a user for each instance, or to dynamically
1065 ba538816 Iustin Pop
allocate a user out of a cluster-wide pool to each instance, with the
1066 ba538816 Iustin Pop
guarantee that no two instances will run under the same user ID on any
1067 ba538816 Iustin Pop
given node.
1068 ba538816 Iustin Pop
1069 ba538816 Iustin Pop
An experimental RAPI client library, that can be used standalone
1070 ba538816 Iustin Pop
(without the other Ganeti libraries), is provided in the source tree as
1071 ba538816 Iustin Pop
``lib/rapi/client.py``. Note this client might change its interface in
1072 ba538816 Iustin Pop
the future, as we iterate on its capabilities.
1073 ba538816 Iustin Pop
1074 ba538816 Iustin Pop
A new command, ``gnt-cluster renew-crypto`` has been added to easily
1075 ba538816 Iustin Pop
replace the cluster's certificates and crypto keys. This might help in
1076 ba538816 Iustin Pop
case they have been compromised, or have simply expired.
1077 ba538816 Iustin Pop
1078 ba538816 Iustin Pop
A new disk option for instance creation has been added that allows one
1079 ba538816 Iustin Pop
to "adopt" currently existing logical volumes, with data
1080 ba538816 Iustin Pop
preservation. This should allow easier migration to Ganeti from
1081 ba538816 Iustin Pop
unmanaged (or managed via other software) instances.
1082 ba538816 Iustin Pop
1083 ba538816 Iustin Pop
Another disk improvement is the possibility to convert between redundant
1084 ba538816 Iustin Pop
(DRBD) and plain (LVM) disk configuration for an instance. This should
1085 ba538816 Iustin Pop
allow better scalability (starting with one node and growing the
1086 ba538816 Iustin Pop
cluster, or shrinking a two-node cluster to one node).
1087 ba538816 Iustin Pop
1088 ba538816 Iustin Pop
A new feature that could help with automated node failovers has been
1089 ba538816 Iustin Pop
implemented: if a node sees itself as offline (by querying the master
1090 ba538816 Iustin Pop
candidates), it will try to shutdown (hard) all instances and any active
1091 ba538816 Iustin Pop
DRBD devices. This reduces the risk of duplicate instances if an
1092 ba538816 Iustin Pop
external script automatically failovers the instances on such nodes. To
1093 ba538816 Iustin Pop
enable this, the cluster parameter ``maintain_node_health`` should be
1094 ba538816 Iustin Pop
enabled; in the future this option (per the name) will enable other
1095 ba538816 Iustin Pop
automatic maintenance features.
1096 ba538816 Iustin Pop
1097 ba538816 Iustin Pop
Instance export/import now will reuse the original instance
1098 ba538816 Iustin Pop
specifications for all parameters; that means exporting an instance,
1099 ba538816 Iustin Pop
deleting it and the importing it back should give an almost identical
1100 ba538816 Iustin Pop
instance. Note that the default import behaviour has changed from
1101 ba538816 Iustin Pop
before, where it created only one NIC; now it recreates the original
1102 ba538816 Iustin Pop
number of NICs.
1103 ba538816 Iustin Pop
1104 ba538816 Iustin Pop
Cluster verify has added a few new checks: SSL certificates validity,
1105 ba538816 Iustin Pop
/etc/hosts consistency across the cluster, etc.
1106 ba538816 Iustin Pop
1107 ba538816 Iustin Pop
Other changes
1108 ba538816 Iustin Pop
~~~~~~~~~~~~~
1109 ba538816 Iustin Pop
1110 ba538816 Iustin Pop
As usual, many internal changes were done, documentation fixes,
1111 ba538816 Iustin Pop
etc. Among others:
1112 ba538816 Iustin Pop
1113 ba538816 Iustin Pop
- Fixed cluster initialization with disabled cluster storage (regression
1114 ba538816 Iustin Pop
  introduced in 2.1.1)
1115 ba538816 Iustin Pop
- File-based storage supports growing the disks
1116 ba538816 Iustin Pop
- Fixed behaviour of node role changes
1117 ba538816 Iustin Pop
- Fixed cluster verify for some corner cases, plus a general rewrite of
1118 ba538816 Iustin Pop
  cluster verify to allow future extension with more checks
1119 ba538816 Iustin Pop
- Fixed log spamming by watcher and node daemon (regression introduced
1120 ba538816 Iustin Pop
  in 2.1.1)
1121 ba538816 Iustin Pop
- Fixed possible validation issues when changing the list of enabled
1122 ba538816 Iustin Pop
  hypervisors
1123 ba538816 Iustin Pop
- Fixed cleanup of /etc/hosts during node removal
1124 ba538816 Iustin Pop
- Fixed RAPI response for invalid methods
1125 ba538816 Iustin Pop
- Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
1126 ba538816 Iustin Pop
- Multiple small improvements to the KVM hypervisor (VNC usage, booting
1127 ba538816 Iustin Pop
  from ide disks, etc.)
1128 ba538816 Iustin Pop
- Allow OS changes without re-installation (to record a changed OS
1129 ba538816 Iustin Pop
  outside of Ganeti, or to allow OS renames)
1130 ba538816 Iustin Pop
- Allow instance creation without OS installation (useful for example if
1131 ba538816 Iustin Pop
  the OS will be installed manually, or restored from a backup not in
1132 ba538816 Iustin Pop
  Ganeti format)
1133 ba538816 Iustin Pop
- Implemented option to make cluster ``copyfile`` use the replication
1134 ba538816 Iustin Pop
  network
1135 ba538816 Iustin Pop
- Added list of enabled hypervisors to ssconf (possibly useful for
1136 ba538816 Iustin Pop
  external scripts)
1137 ba538816 Iustin Pop
- Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
1138 ba538816 Iustin Pop
  1.2 clusters
1139 ba538816 Iustin Pop
- A partial form of node re-IP is possible via node readd, which now
1140 ba538816 Iustin Pop
  allows changed node primary IP
1141 ba538816 Iustin Pop
- Command line utilities now show an informational message if the job is
1142 ba538816 Iustin Pop
  waiting for a lock
1143 ba538816 Iustin Pop
- The logs of the master daemon now show the PID/UID/GID of the
1144 ba538816 Iustin Pop
  connected client

1151 bdc93557 Iustin Pop
1152 c655522d Iustin Pop
During the 2.1.0 long release candidate cycle, a lot of improvements and
1153 c655522d Iustin Pop
changes have accumulated with were released later as 2.1.1.
1154 c655522d Iustin Pop
1155 c655522d Iustin Pop
Major changes
1156 c655522d Iustin Pop
~~~~~~~~~~~~~
1157 c655522d Iustin Pop
1158 c655522d Iustin Pop
The node evacuate command (``gnt-node evacuate``) was significantly
1159 c655522d Iustin Pop
rewritten, and as such the IAllocator protocol was changed - a new
1160 c655522d Iustin Pop
request type has been added. This unfortunate change during a stable
1161 c655522d Iustin Pop
series is designed to improve performance of node evacuations; on
1162 c655522d Iustin Pop
clusters with more than about five nodes and which are well-balanced,
1163 c655522d Iustin Pop
evacuation should proceed in parallel for all instances of the node
1164 c655522d Iustin Pop
being evacuated. As such, any existing IAllocator scripts need to be
1165 c655522d Iustin Pop
updated, otherwise the above command will fail due to the unknown
1166 c655522d Iustin Pop
request. The provided "dumb" allocator has not been updated; but the
1167 c655522d Iustin Pop
ganeti-htools package supports the new protocol since version 0.2.4.
1168 c655522d Iustin Pop
1169 c655522d Iustin Pop
Another important change is increased validation of node and instance
1170 c655522d Iustin Pop
names. This might create problems in special cases, if invalid host
1171 c655522d Iustin Pop
names are being used.
1172 c655522d Iustin Pop
1173 c655522d Iustin Pop
Also, a new layer of hypervisor parameters has been added, that sits at
1174 c655522d Iustin Pop
OS level between the cluster defaults and the instance ones. This allows
1175 c655522d Iustin Pop
customisation of virtualization parameters depending on the installed
1176 c655522d Iustin Pop
OS. For example instances with OS 'X' may have a different KVM kernel
1177 c655522d Iustin Pop
(or any other parameter) than the cluster defaults. This is intended to
1178 c655522d Iustin Pop
help managing a multiple OSes on the same cluster, without manual
1179 c655522d Iustin Pop
modification of each instance's parameters.
1180 c655522d Iustin Pop
1181 c655522d Iustin Pop
A tool for merging clusters, ``cluster-merge``, has been added in the
1182 c655522d Iustin Pop
tools sub-directory.

- Improved the int/float conversions that should make the code more
1188 c655522d Iustin Pop
  robust in face of errors from the node daemons
1189 c655522d Iustin Pop
- Fixed the remove node code in case of internal configuration errors
1190 c655522d Iustin Pop
- Fixed the node daemon behaviour in face of inconsistent queue
1191 c655522d Iustin Pop
  directory (e.g. read-only file-system where we can't open the files
1192 c655522d Iustin Pop
  read-write, etc.)
1193 c655522d Iustin Pop
- Fixed the behaviour of gnt-node modify for master candidate demotion;
1194 df3df936 Michael Hanselmann
  now it either aborts cleanly or, if given the new "auto_promote"
1195 c655522d Iustin Pop
  parameter, will automatically promote other nodes as needed
1196 c655522d Iustin Pop
- Fixed compatibility with (unreleased yet) Python 2.6.5 that would
1197 c655522d Iustin Pop
  completely prevent Ganeti from working
1198 c655522d Iustin Pop
- Fixed bug for instance export when not all disks were successfully
1199 c655522d Iustin Pop
  exported
1200 c655522d Iustin Pop
- Fixed behaviour of node add when the new node is slow in starting up
1201 c655522d Iustin Pop
  the node daemon
1202 c655522d Iustin Pop
- Fixed handling of signals in the LUXI client, which should improve
1203 c655522d Iustin Pop
  behaviour of command-line scripts
1204 c655522d Iustin Pop
- Added checks for invalid node/instance names in the configuration (now
1205 c655522d Iustin Pop
  flagged during cluster verify)
1206 c655522d Iustin Pop
- Fixed watcher behaviour for disk activation errors
1207 c655522d Iustin Pop
- Fixed two potentially endless loops in http library, which led to the
1208 c655522d Iustin Pop
  RAPI daemon hanging and consuming 100% CPU in some cases
1209 c655522d Iustin Pop
- Fixed bug in RAPI daemon related to hashed passwords
1210 c655522d Iustin Pop
- Fixed bug for unintended qemu-level bridging of multi-NIC KVM
1211 c655522d Iustin Pop
  instances
1212 c655522d Iustin Pop
- Enhanced compatibility with non-Debian OSes, but not using absolute
1213 c655522d Iustin Pop
  path in some commands and allowing customisation of the ssh
1214 c655522d Iustin Pop
  configuration directory
1215 c655522d Iustin Pop
- Fixed possible future issue with new Python versions by abiding to the
1216 c655522d Iustin Pop
  proper use of ``__slots__`` attribute on classes
1217 c655522d Iustin Pop
- Added checks that should prevent directory traversal attacks
1218 c655522d Iustin Pop
- Many documentation fixes based on feedback from users
1219 c655522d Iustin Pop
1220 c655522d Iustin Pop
New features
1221 c655522d Iustin Pop
~~~~~~~~~~~~
1222 c655522d Iustin Pop
1223 df3df936 Michael Hanselmann
- Added an "early_release" more for instance replace disks and node
1224 c655522d Iustin Pop
  evacuate, where we release locks earlier and thus allow higher
1225 c655522d Iustin Pop
  parallelism within the cluster
1226 c655522d Iustin Pop
- Added watcher hooks, intended to allow the watcher to restart other
1227 c655522d Iustin Pop
  daemons (e.g. from the ganeti-nbma project), but they can be used of
1228 c655522d Iustin Pop
  course for any other purpose
1229 c655522d Iustin Pop
- Added a compile-time disable for DRBD barriers, to increase
1230 c655522d Iustin Pop
  performance if the administrator trusts the power supply or the
1231 c655522d Iustin Pop
  storage system to not lose writes
1232 c655522d Iustin Pop
- Added the option of using syslog for logging instead of, or in
1233 c655522d Iustin Pop
  addition to, Ganeti's own log files
1234 c655522d Iustin Pop
- Removed boot restriction for paravirtual NICs for KVM, recent versions
1235 c655522d Iustin Pop
  can indeed boot from a paravirtual NIC
1236 c655522d Iustin Pop
- Added a generic debug level for many operations; while this is not
1237 c655522d Iustin Pop
  used widely yet, it allows one to pass the debug value all the way to
1238 c655522d Iustin Pop
  the OS scripts
1239 c655522d Iustin Pop
- Enhanced the hooks environment for instance moves (failovers,
1240 c655522d Iustin Pop
  migrations) where the primary/secondary nodes changed during the
1241 c655522d Iustin Pop
  operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
1242 c655522d Iustin Pop
- Enhanced data validations for many user-supplied values; one important
1243 c655522d Iustin Pop
  item is the restrictions imposed on instance and node names, which
1244 c655522d Iustin Pop
  might reject some (invalid) host names
1245 c655522d Iustin Pop
- Add a configure-time option to disable file-based storage, if it's not
1246 c655522d Iustin Pop
  needed; this allows greater security separation between the master
1247 c655522d Iustin Pop
  node and the other nodes from the point of view of the inter-node RPC
1248 c655522d Iustin Pop
  protocol
1249 c655522d Iustin Pop
- Added user notification in interactive tools if job is waiting in the
1250 c655522d Iustin Pop
  job queue or trying to acquire locks
1251 c655522d Iustin Pop
- Added log messages when a job is waiting for locks
1252 c655522d Iustin Pop
- Added filtering by node tags in instance operations which admit
1253 c655522d Iustin Pop
  multiple instances (start, stop, reboot, reinstall)
1254 c655522d Iustin Pop
- Added a new tool for cluster mergers, ``cluster-merge``
1255 c655522d Iustin Pop
- Parameters from command line which are of the form ``a=b,c=d`` can now
1256 c655522d Iustin Pop
  use backslash escapes to pass in values which contain commas,
1257 c655522d Iustin Pop
  e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
1258 c655522d Iustin Pop
  ``b,c``
1259 c655522d Iustin Pop
- For KVM, the instance name is the first parameter passed to KVM, so
1260 c655522d Iustin Pop
  that it's more visible in the process list
1261 c655522d Iustin Pop

Ganeti 2.1 brings many improvements with it. Major changes:
1269 920a91bf Michael Hanselmann
1270 920a91bf Michael Hanselmann
- Added infrastructure to ease automated disk repairs
1271 920a91bf Michael Hanselmann
- Added new daemon to export configuration data in a cheaper way than
1272 920a91bf Michael Hanselmann
  using the remote API
1273 920a91bf Michael Hanselmann
- Instance NICs can now be routed instead of being associated with a
1274 920a91bf Michael Hanselmann
  networking bridge
1275 920a91bf Michael Hanselmann
- Improved job locking logic to reduce impact of jobs acquiring multiple
1276 920a91bf Michael Hanselmann
  locks waiting for other long-running jobs
1277 920a91bf Michael Hanselmann
1278 bfe61b0b Iustin Pop

1435 bdc93557 Iustin Pop
1436 61b5e342 Michael Hanselmann
- Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
1437 61b5e342 Michael Hanselmann

*(Released Fri, 17 Jul 2009)*
1453 bdc93557 Iustin Pop
1454 61b5e342 Michael Hanselmann
- Added experimental support for stripped logical volumes; this should
1455 61b5e342 Michael Hanselmann
  enhance performance but comes with a higher complexity in the block
1456 61b5e342 Michael Hanselmann
  device handling; stripping is only enabled when passing
1457 61b5e342 Michael Hanselmann
  ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
1458 61b5e342 Michael Hanselmann
  affected even in the non-stripped mode
1459 61b5e342 Michael Hanselmann
- Improved resiliency against transient failures at the end of DRBD
1460 61b5e342 Michael Hanselmann
  resyncs, and in general of DRBD resync checks
1461 61b5e342 Michael Hanselmann
- Fixed a couple of issues with exports and snapshot errors
1462 61b5e342 Michael Hanselmann
- Fixed a couple of issues in instance listing
1463 61b5e342 Michael Hanselmann
- Added display of the disk size in ``gnt-instance info``
1464 61b5e342 Michael Hanselmann
- Fixed checking for valid OSes in instance creation
1465 aa287e8c Michael Hanselmann
- Fixed handling of the "vcpus" parameter in instance listing and in
1466 61b5e342 Michael Hanselmann
  general of invalid parameters
1467 61b5e342 Michael Hanselmann
- Fixed http server library, and thus RAPI, to handle invalid
1468 61b5e342 Michael Hanselmann
  username/password combinations correctly; this means that now they
1469 61b5e342 Michael Hanselmann
  report unauthorized for queries too, not only for modifications,
1470 61b5e342 Michael Hanselmann
  allowing earlier detect of configuration problems
1471 aa287e8c Michael Hanselmann
- Added a new "role" node list field, equivalent to the master/master
1472 61b5e342 Michael Hanselmann
  candidate/drained/offline flags combinations
1473 61b5e342 Michael Hanselmann
- Fixed cluster modify and changes of candidate pool size
1474 61b5e342 Michael Hanselmann

1475 61b5e342 Michael Hanselmann
- Fixed a couple of issues with node demotion from master candidate role
1476 61b5e342 Michael Hanselmann
- Fixed node readd issues
1477 61b5e342 Michael Hanselmann
- Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
1478 aa287e8c Michael Hanselmann

1479 aa287e8c Michael Hanselmann
  on two-nodes clusters when the former master node is unreachable
1480 61b5e342 Michael Hanselmann

1486 bdc93557 Iustin Pop
*(Released Tue, 16 Jun 2009)*
1487 bdc93557 Iustin Pop
1488 61b5e342 Michael Hanselmann
- added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
1489 61b5e342 Michael Hanselmann
  allow re-adding the start in single-user option (regression from 1.2)
1490 61b5e342 Michael Hanselmann
- the watcher writes the instance status to a file, to allow monitoring
1491 61b5e342 Michael Hanselmann
  to report the instance status (from the master) based on cached
1492 61b5e342 Michael Hanselmann
  results of the watcher's queries; while this can get stale if the
1493 61b5e342 Michael Hanselmann
  watcher is being locked due to other work on the cluster, this is
1494 61b5e342 Michael Hanselmann
  still an improvement
1495 61b5e342 Michael Hanselmann
- the watcher now also restarts the node daemon and the rapi daemon if
1496 61b5e342 Michael Hanselmann
  they died
1497 61b5e342 Michael Hanselmann
- fixed the watcher to handle full and drained queue cases
1498 7faf5110 Michael Hanselmann
- hooks export more instance data in the environment, which helps if
1499 7faf5110 Michael Hanselmann
  hook scripts need to take action based on the instance's properties
1500 7faf5110 Michael Hanselmann
  (no longer need to query back into ganeti)
1501 61b5e342 Michael Hanselmann
- instance failovers when the instance is stopped do not check for free
1502 61b5e342 Michael Hanselmann
  RAM, so that failing over a stopped instance is possible in low memory
1503 61b5e342 Michael Hanselmann
  situations
1504 61b5e342 Michael Hanselmann
- rapi uses queries for tags instead of jobs (for less job traffic), and
1505 61b5e342 Michael Hanselmann
  for cluster tags it won't talk to masterd at all but read them from
1506 61b5e342 Michael Hanselmann
  ssconf
1507 61b5e342 Michael Hanselmann
- a couple of error handling fixes in RAPI
1508 61b5e342 Michael Hanselmann
- drbd handling: improved the error handling of inconsistent disks after
1509 61b5e342 Michael Hanselmann
  resync to reduce the frequency of "there are some degraded disks for
1510 61b5e342 Michael Hanselmann
  this instance" messages
1511 61b5e342 Michael Hanselmann
- fixed a bug in live migration when DRBD doesn't want to reconnect (the
1512 61b5e342 Michael Hanselmann
  error handling path called a wrong function name)

1539 61b5e342 Michael Hanselmann
- change the OS list to not require locks; this helps with big clusters
1540 61b5e342 Michael Hanselmann
- fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
1541 61b5e342 Michael Hanselmann

1542 61b5e342 Michael Hanselmann

1543 61b5e342 Michael Hanselmann
  instances anymore; either pass ``--all`` or pass the desired
1544 61b5e342 Michael Hanselmann

*(Released Thu, 19 Feb 2009)*
1594 bdc93557 Iustin Pop

- Xen PVM and KVM have switched the default value for the instance root
1596 61b5e342 Michael Hanselmann
  disk to the first partition on the first drive, instead of the whole
1597 61b5e342 Michael Hanselmann
  drive; this means that the OS installation scripts must be changed
1598 61b5e342 Michael Hanselmann
  accordingly
1599 61b5e342 Michael Hanselmann
- Man pages have been updated
1600 61b5e342 Michael Hanselmann

1613 61b5e342 Michael Hanselmann
- Version 2 is a general rewrite of the code and therefore the
1614 61b5e342 Michael Hanselmann
  differences are too many to list, see the design document for 2.0 in
1615 61b5e342 Michael Hanselmann
  the ``doc/`` subdirectory for more details
1616 61b5e342 Michael Hanselmann
- In this beta version there is not yet a migration path from 1.2 (there
1617 61b5e342 Michael Hanselmann
  will be one in the final 2.0 release)
1618 61b5e342 Michael Hanselmann
- A few significant changes are:
1619 61b5e342 Michael Hanselmann
1620 61b5e342 Michael Hanselmann
  - all commands are executed by a daemon (``ganeti-masterd``) and the
1621 61b5e342 Michael Hanselmann
    various ``gnt-*`` commands are just front-ends to it
1622 7faf5110 Michael Hanselmann
  - all the commands are entered into, and executed from a job queue,
1623 7faf5110 Michael Hanselmann
    see the ``gnt-job(8)`` manpage
1624 7faf5110 Michael Hanselmann
  - the RAPI daemon supports read-write operations, secured by basic
1625 7faf5110 Michael Hanselmann
    HTTP authentication on top of HTTPS
1626 61b5e342 Michael Hanselmann
  - DRBD version 0.7 support has been removed, DRBD 8 is the only
1627 61b5e342 Michael Hanselmann
    supported version (when migrating from Ganeti 1.2 to 2.0, you need
1628 61b5e342 Michael Hanselmann
    to migrate to DRBD 8 first while still running Ganeti 1.2)
1629 61b5e342 Michael Hanselmann
  - DRBD devices are using statically allocated minor numbers, which
1630 61b5e342 Michael Hanselmann
    will be assigned to existing instances during the migration process
1631 61b5e342 Michael Hanselmann
  - there is support for both Xen PVM and Xen HVM instances running on
1632 61b5e342 Michael Hanselmann
    the same cluster
1633 61b5e342 Michael Hanselmann
  - KVM virtualization is supported too
1634 61b5e342 Michael Hanselmann
  - file-based storage has been implemented, which means that it is
1635 61b5e342 Michael Hanselmann
    possible to run the cluster without LVM and DRBD storage, for
1636 61b5e342 Michael Hanselmann
    example using a shared filesystem exported from shared storage (and
1637 61b5e342 Michael Hanselmann
    still have live migration)

1675 7faf5110 Michael Hanselmann
- instance auto_balance flag, set by default. If turned off it will
1676 7faf5110 Michael Hanselmann
  avoid warnings on cluster verify if there is not enough memory to fail
1677 7faf5110 Michael Hanselmann
  over an instance. in the future it will prevent automatically failing
1678 7faf5110 Michael Hanselmann
  it over when we will support that.
1679 61b5e342 Michael Hanselmann
- batcher tool for instance creation, see ``tools/README.batcher``
1680 61b5e342 Michael Hanselmann

1681 61b5e342 Michael Hanselmann
  operating system when reinstalling an instance.
1682 61b5e342 Michael Hanselmann
- when changing the memory amount on instance modify a check has been
1683 61b5e342 Michael Hanselmann
  added that the instance will be able to start. also warnings are
1684 61b5e342 Michael Hanselmann
  emitted if the instance will not be able to fail over, if auto_balance
1685 61b5e342 Michael Hanselmann
  is true.

  automatically started on master node, TCP port 5080, if enabled by
1718 61b5e342 Michael Hanselmann
  ``--enable-rapi`` parameter to configure script.
1719 61b5e342 Michael Hanselmann
- Instance allocator support. Add and import instance accept a
1720 61b5e342 Michael Hanselmann
  ``--iallocator`` parameter, and call that instance allocator to decide
1721 61b5e342 Michael Hanselmann
  which node to use for the instance. The iallocator document describes
1722 61b5e342 Michael Hanselmann
  what's expected from an allocator script.
1723 61b5e342 Michael Hanselmann
- ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
1724 61b5e342 Michael Hanselmann
  ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a

1726 61b5e342 Michael Hanselmann
  that reside on it.
1727 61b5e342 Michael Hanselmann
- ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
1728 61b5e342 Michael Hanselmann
  ``gnt-cluster verify``, to check for site-specific compliance. All the
1729 61b5e342 Michael Hanselmann
  hooks will run, and their output, if any, will be displayed. Any
1730 61b5e342 Michael Hanselmann
  failing hook will make the verification return an error value.
1731 61b5e342 Michael Hanselmann
- ``gnt-cluster verify`` now checks that its peers are reachable on the
1732 61b5e342 Michael Hanselmann
  primary and secondary interfaces
1733 61b5e342 Michael Hanselmann
- ``gnt-node add`` now supports the ``--readd`` option, to readd a node
1734 61b5e342 Michael Hanselmann
  that is still declared as part of the cluster and has failed.
1735 61b5e342 Michael Hanselmann
- ``gnt-* list`` commands now accept a new ``-o +field`` way of
1736 61b5e342 Michael Hanselmann
  specifying output fields, that just adds the chosen fields to the
1737 61b5e342 Michael Hanselmann
  default ones.
1738 61b5e342 Michael Hanselmann
- ``gnt-backup`` now has a new ``remove`` command to delete an existing
1739 61b5e342 Michael Hanselmann
  export from the filesystem.
1740 61b5e342 Michael Hanselmann
- New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
1741 61b5e342 Michael Hanselmann
  have been added. Using them you can enable/disable acpi and pae
1742 61b5e342 Michael Hanselmann
  support, and specify a path for a cd image to be exported to the
1743 61b5e342 Michael Hanselmann
  instance. These parameters as the name suggest only work on HVM
1744 61b5e342 Michael Hanselmann
  clusters.
1745 61b5e342 Michael Hanselmann
- When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
1746 61b5e342 Michael Hanselmann
  PAE support will be set to the previously hardcoded values, but the
1747 61b5e342 Michael Hanselmann
  (previously hardcoded) path to the CDROM ISO image will be unset and
1748 61b5e342 Michael Hanselmann
  if required, needs to be set manually with ``gnt-instance modify``
1749 61b5e342 Michael Hanselmann
  after the upgrade.
1750 61b5e342 Michael Hanselmann
- The address to which an instance's VNC console is bound is now
1751 61b5e342 Michael Hanselmann
  selectable per-instance, rather than being cluster wide. Of course
1752 61b5e342 Michael Hanselmann
  this only applies to instances controlled via VNC, so currently just
1753 61b5e342 Michael Hanselmann
  applies to HVM clusters.
