enables rolling upgrades of DRBD with no downtime. As permanent operation
of different DRBD versions within a node group is discouraged,
``gnt-cluster verify`` will emit a warning if it detects such a situation.
+- hroller now also plans for capacity to move non-redundant instances off
+ any node to be rebooted; the old behavior of completely ignoring any
+ non-redundant instances can be restored by adding the --ignore-non-redundant
+ option.
+- The cluster option '--no-lvm-storage' was removed in favor of the new option
+ '--enabled-disk-templates'.
+- On instance creation, disk templates no longer need to be specified
+ with '-t'. The default disk template will be taken from the list of
+ enabled disk templates.
+- New "inst-status-xen" data collector for the monitoring daemon, providing
+ information about the state of the xen instances on the nodes.
+- New "lv" data collector for the monitoring daemon, collecting data about the
+ logical volumes on the nodes, and pairing them with the name of the instances
+ they belong to.
+- New "diskstats" data collector, collecting the data from /proc/diskstats and
+ presenting them over the monitoring daemon interface.
+- The monitoring daemon is now running as root, in order to be able to collect
+ information only available to root (such as the state of Xen instances).
+- The ConfD client is now IPv6 compatible.
+- File storage is no longer dis/enabled at configure time, but using the
+ option '--enabled-disk-templates' at cluster initialization and
+ modification.
+- The default directory for file storage is not anymore specified at
+ configure time, but taken from the cluster's configuration. It can be
+ set at cluster initialization and modification with '--file-storage-dir'.
+- Cluster verification now includes stricter checks regarding the
+ default file storage dir. It now checks that the file storage
+ directory is explicitely allowed in the 'file-storage-paths' file and
+ that the directory exists on all nodes.
Version 2.8.0 beta1

+
+Incompatible/important changes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- Instance policy can contain multiple instance specs, as described in
+ the “Constrained instance sizes” section of :doc:`Partitioned Ganeti
+ <design-partitioned>`. As a consequence, it's not possible to partially change
+ or override instance specs. Bounding specs (min and max) can be specified as a
+ whole using the new option ``--ipolicy-bounds-specs``, while standard
+ specs use the new option ``--ipolicy-std-specs``.
+- The output of the info command of gnt-cluster, gnt-group, gnt-node,
+ gnt-instance is a valid YAML object.
+- hail now honors network restrictions when allocating nodes. This led to an
+ update of the IAllocator protocol. See the IAllocator documentation for
+ details.
+
+New features
+~~~~~~~~~~~~
-- The minimum Python version needed to run Ganeti is now 2.6.
- The :doc:`Remote API <rapi>` daemon now supports a command line flag
to always require authentication, ``--require-authentication``. It can
be specified in ``$sysconfdir/default/ganeti``.
creation.
- ``cfgupgrade`` now supports a ``--downgrade`` option to bring the
configuration back to the previous stable version.
-- The cluster option '--no-lvm-storage' was removed in favor of the new option
- '--enabled-disk-templates'.
+- Disk templates in group ipolicy can be restored to the default value.
+- Initial support for diskless instances and virtual clusters in QA.
+- More QA and unit tests for instance policies.
+- Every opcode now contains a reason trail (visible through ``gnt-job info``)
+ describing why the opcode itself was executed.
+- The monitoring daemon is now available. It allows users to query the cluster
+ for obtaining information about the status of the system. The daemon is only
+ responsible for providing the information over the network: the actual data
+ gathering is performed by data collectors (currently, only the DRBD status
+ collector is available).
+- In order to help developers work on Ganeti, a new script
+ (``devel/build_chroot``) is provided, for building a chroot that contains all
+ the required development libraries and tools for compiling Ganeti on a Debian
+ Squeeze system.
+- A new tool, ``harep``, for performing self-repair and recreation of instances
+ in Ganeti has been added.
+- Split queries are enabled for tags, network, exports, cluster info, groups,
+ jobs, nodes.
+- New command ``show-ispecs-cmd`` for ``gnt-cluster`` and ``gnt-group``.
+ It prints the command line to set the current policies, to ease
+ changing them.
+
+New dependencies
+~~~~~~~~~~~~~~~~
+The following new dependencies have been added:
+For Haskell:
+- The ``curl`` library is not optional anymore for compiling the Haskell code.
+- ``snap-server`` library (if monitoring is enabled).
-Version 2.7.0 rc2
------------------
+For Python:
+- The minimum Python version needed to run Ganeti is now 2.6.
+- ``yaml`` library (only for running the QA).
-*(unreleased)*
-- ``devel/upload`` now works when ``/var/run`` on the target nodes is a
- symlink.
-- Disks added through ``gnt-instance modify`` or created through
- ``gnt-instance recreate-disks`` are wiped, if the
- ``prealloc_wipe_disks`` flag is set.
-- If wiping newly created disks fails, the disks are removed. Also,
- partial failures in creating disks through ``gnt-instance modify``
- triggers a cleanup of the partially-created disks.
-- Removing the master IP address doesn't fail if the address has been
- already removed.
