Version 2.7.0 beta1
-------------------
-*(unreleased)*
+*(Released Wed, 6 Feb 2013)*
- ``gnt-instance batch-create`` has been changed to use the bulk create
opcode from Ganeti. This lead to incompatible changes in the format of
<rapi>` interface and when an instance allocator is used. If the
``opportunistic_locking`` parameter is set the opcode will try to
acquire as many locks as possible, but will not wait for any locks
- held by other opcodes. If the not enough resources can be found to
+ held by other opcodes. If not enough resources can be found to
allocate the instance, the temporary error code
:pyeval:`errors.ECODE_TEMP_NORES` is returned. The operation can be
retried thereafter, with or without opportunistic locking.
+- The functionality for allocating multiple instances at once has been
+ overhauled and is now also available through :doc:`RAPI <rapi>`.
- Man pages can now be included when the documentation is built, in
which case the output is in ``doc/man-html``. The configure-time
option is ``--enable-manpages-in-doc``. Sphinx 1.0 or higher is
required.
+- A new htool called ``hroller`` helps scheduling parallel shutdown of
+ nodes on clusters where all instances are shut down, but without ever
+ rebooting both primary and secondary node for an instance at the same
+ time.
+- Queries not needing locks or RPC access to the node can now be
+ performed by the confd daemon, making them independent from jobs, and
+ thus faster to execute. This is selectable at configure time.
+- The KVM hypervisor has been updated with many new hypervisor
+ parameters, including a generic one for passing arbitrary command line
+ values. See a complete list in :manpage:`gnt-instance(8)`.
+- A new tool, called ``mon-collector``, is the stand-alone executor of
+ the data collectors for a monitoring system. As of this version, it
+ just includes the DRBD data collector, that can be executed by calling
+ ``mon-collector`` using the ``drbd`` parameter. See
+ :manpage:`mon-collector(7)`.
+- New ``exclusive-storage`` node parameter added. When it's set to true,
+ physical disks are assigned in an exclusive fashion to instances, as
+ documented in :doc:`Partitioned Ganeti <design-partitioned>`.
+ Currently, only instances using the ``plain`` disk template are
+ supported.
+- New network management functionality to support automatic allocation
+ of IP addresses and managing of network parameters. See
+ :manpage:`gnt-network(8)` for more details.
+- New external storage backend, to allow managing arbitrary storage
+ systems external to the cluster. See
+ :manpage:`ganeti-extstorage-interface(7)`.
+- Instance renames of LVM-based instances will now update the LV tags
+ (which can be used to recover the instance-to-LV mapping in case of
+ emergencies)
