-Version 2.5.0 beta1
+
+Version 2.6.0 beta1
-------------------
*(unreleased)*
+- Deprecated ``admin_up`` instance field. Instead, ``admin_state`` is
+ introduced, with 3 possible values -- ``up``, ``down`` and
+ ``offline``.
+- Replaced ``--disks`` option of ``gnt-instance replace-disks`` with a
+ more flexible ``--disk`` option. Now disk size and mode can be changed
+ upon recreation.
+- Removed deprecated ``QueryLocks`` LUXI request. Use
+ ``Query(what=QR_LOCK, ...)`` instead.
+- The LUXI requests :pyeval:`luxi.REQ_QUERY_JOBS`,
+ :pyeval:`luxi.REQ_QUERY_INSTANCES`, :pyeval:`luxi.REQ_QUERY_NODES`,
+ :pyeval:`luxi.REQ_QUERY_GROUPS`, :pyeval:`luxi.REQ_QUERY_EXPORTS` and
+ :pyeval:`luxi.REQ_QUERY_TAGS` are deprecated and will be removed in a
+ future version. :pyeval:`luxi.REQ_QUERY` should be used instead.
+- RAPI client: ``CertificateError`` now derives from ``GanetiApiError``
+- Deprecation warnings due to PyCrypto/paramiko import in
+ ``tools/setup-ssh`` have been silenced, as usually they are safe;
+ please make sure to run an up-to-date paramiko version
+- The QA scripts now depend on Python 2.5 or above
+
+
+Version 2.5.1
+-------------
+
+*(Released Fri, 11 May 2012)*
+
+A small bugfix release.
+
+The main issues solved are on the topic of compatibility with newer LVM
+releases:
+
+- fixed parsing of ``lv_attr`` field
+- adapted to new ``vgreduce --removemissing`` behaviour where sometimes
+ the ``--force`` flag is needed
+
+Also on the topic of compatibility, ``tools/lvmstrap`` has been changed
+to accept kernel 3.x too (was hardcoded to 2.6.*).
+
+A regression present in 2.5.0 that broke handling (in the gnt-* scripts)
+of hook results and that also made display of other errors suboptimal
+was fixed; the code behaves now like 2.4 and earlier.
+
+Another change in 2.5, the cleanup of the OS scripts environment, is too
+aggressive: it removed even the ``PATH`` variable, which requires the OS
+scripts to *always* need to export it. Since this is a bit too strict,
+we now export a minimal PATH, the same that we export for hooks.
+
+The fix for issue 201 (Preserve bridge MTU in KVM ifup script) was
+integrated into this release.
+
+Finally, a few other miscellaneous changes were done (no new features,
+just small improvements):
+
+- Fix ``gnt-group --help`` display
+- Fix hardcoded Xen kernel path
+- Fix grow-disk handling of invalid units
+- Update synopsis for ``gnt-cluster repair-disk-sizes``
+- Accept both PUT and POST in noded (makes future upgrade to 2.6 easier)
+
+
+Version 2.5.0
+-------------
+
+*(Released Thu, 12 Apr 2012)*
+
+Incompatible/important changes and bugfixes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
- The default of the ``/2/instances/[instance_name]/rename`` RAPI
resource's ``ip_check`` parameter changed from ``True`` to ``False``
- to match the underlying LUXI interface
+ to match the underlying LUXI interface.
+- The ``/2/nodes/[node_name]/evacuate`` RAPI resource was changed to use
+ body parameters, see :doc:`RAPI documentation <rapi>`. The server does
+ not maintain backwards-compatibility as the underlying operation
+ changed in an incompatible way. The RAPI client can talk to old
+ servers, but it needs to be told so as the return value changed.
- When creating file-based instances via RAPI, the ``file_driver``
- parameter no longer defaults to ``loop`` and must be specified
-- The deprecated "bridge" nic parameter is no longer supported. Use
- "link" instead.
+ parameter no longer defaults to ``loop`` and must be specified.
+- The deprecated ``bridge`` NIC parameter is no longer supported. Use
+ ``link`` instead.
- Support for the undocumented and deprecated RAPI instance creation
request format version 0 has been dropped. Use version 1, supported
since Ganeti 2.1.3 and :doc:`documented <rapi>`, instead.
- Pyparsing 1.4.6 or above is required, see :doc:`installation
- documentation <install>`
+ documentation <install>`.
+- The "cluster-verify" hooks are now executed per group by the
+ ``OP_CLUSTER_VERIFY_GROUP`` opcode. This maintains the same behavior
+ if you just run ``gnt-cluster verify``, which generates one opcode per
+ group.
+- The environment as passed to the OS scripts is cleared, and thus no
+ environment variables defined in the node daemon's environment will be
+ inherited by the scripts.
+- The :doc:`iallocator <iallocator>` mode ``multi-evacuate`` has been
+ deprecated.
+- :doc:`New iallocator modes <design-multi-reloc>` have been added to
+ support operations involving multiple node groups.
+- Offline nodes are ignored when failing over an instance.
+- Support for KVM version 1.0, which changed the version reporting format
+ from 3 to 2 digits.
+- TCP/IP ports used by DRBD disks are returned to a pool upon instance
+ removal.
+- ``Makefile`` is now compatible with Automake 1.11.2
+- Includes all bugfixes made in the 2.4 series
+New features
+~~~~~~~~~~~~
-Version 2.4.3
+- The ganeti-htools project has been merged into the ganeti-core source
+ tree and will be built as part of Ganeti (see :doc:`install-quick`).
+- Implemented support for :doc:`shared storage <design-shared-storage>`.
+- Add support for disks larger than 2 TB in ``lvmstrap`` by supporting
+ GPT-style partition tables (requires `parted
+ <http://www.gnu.org/s/parted/>`_).
+- Added support for floppy drive and 2nd CD-ROM drive in KVM hypervisor.
+- Allowed adding tags on instance creation.
+- Export instance tags to hooks (``INSTANCE_TAGS``, see :doc:`hooks`)
+- Allow instances to be started in a paused state, enabling the user to
+ see the complete console output on boot using the console.
+- Added new hypervisor flag to control default reboot behaviour
+ (``reboot_behavior``).
+- Added support for KVM keymaps (hypervisor parameter ``keymap``).
+- Improved out-of-band management support:
+
+ - Added ``gnt-node health`` command reporting the health status of
+ nodes.
+ - Added ``gnt-node power`` command to manage power status of nodes.
+ - Added command for emergency power-off (EPO), ``gnt-cluster epo``.
+
+- Instance migration can fall back to failover if instance is not
+ running.
+- Filters can be used when listing nodes, instances, groups and locks;
+ see *ganeti(7)* manpage.
+- Added post-execution status as variables to :doc:`hooks <hooks>`
+ environment.
+- Instance tags are exported/imported together with the instance.
+- When given an explicit job ID, ``gnt-job info`` will work for archived
+ jobs.
+- Jobs can define dependencies on other jobs (not yet supported via
+ RAPI or command line, but used by internal commands and usable via
+ LUXI).
+
+ - Lock monitor (``gnt-debug locks``) shows jobs waiting for
+ dependencies.
+
+- Instance failover is now available as a RAPI resource
+ (``/2/instances/[instance_name]/failover``).
+- ``gnt-instance info`` defaults to static information if primary node
+ is offline.
+- Opcodes have a new ``comment`` attribute.
+- Added basic SPICE support to KVM hypervisor.
+- ``tools/ganeti-listrunner`` allows passing of arguments to executable.
+
+Node group improvements
+~~~~~~~~~~~~~~~~~~~~~~~
+
+- ``gnt-cluster verify`` has been modified to check groups separately,
+ thereby improving performance.
+- Node group support has been added to ``gnt-cluster verify-disks``,
+ which now operates per node group.
+- Watcher has been changed to work better with node groups.
+
+ - One process and state file per node group.
+ - Slow watcher in one group doesn't block other group's watcher.
+
+- Added new command, ``gnt-group evacuate``, to move all instances in a
+ node group to other groups.
+- Added ``gnt-instance change-group`` to move an instance to another
+ node group.
+- ``gnt-cluster command`` and ``gnt-cluster copyfile`` now support
+ per-group operations.
+- Node groups can be tagged.
+- Some operations switch from an exclusive to a shared lock as soon as
+ possible.
+- Instance's primary and secondary nodes' groups are now available as
+ query fields (``pnode.group``, ``pnode.group.uuid``, ``snodes.group``
+ and ``snodes.group.uuid``).
+
+Misc
+~~~~
+
+- Numerous updates to documentation and manpages.
+
+ - :doc:`RAPI <rapi>` documentation now has detailed parameter
+ descriptions.
+ - Some opcode/job results are now also documented, see :doc:`RAPI
+ <rapi>`.
+
+- A lockset's internal lock is now also visible in lock monitor.
+- Log messages from job queue workers now contain information about the
+ opcode they're processing.
+- ``gnt-instance console`` no longer requires the instance lock.
+- A short delay when waiting for job changes reduces the number of LUXI
+ requests significantly.
+- DRBD metadata volumes are overwritten with zeros during disk creation.
+- Out-of-band commands no longer acquire the cluster lock in exclusive
+ mode.
+- ``devel/upload`` now uses correct permissions for directories.
