-Version 2.7.0 beta1
--------------------
+*(Released Mon, 22 Apr 2013)*
-*(Released Wed, 6 Feb 2013)*
+Incompatible/important changes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+- Instance policies for disk size were documented to be on a per-disk
+ basis, but hail applied them to the sum of all disks. This has been
+ fixed.
+- ``hbal`` will now exit with status 0 if, during job execution over
+ LUXI, early exit has been requested and all jobs are successful;
+ before, exit status 1 was used, which cannot be differentiated from
+ "job error" case
+- Compatibility with newer versions of rbd has been fixed
- ``gnt-instance batch-create`` has been changed to use the bulk create
opcode from Ganeti. This lead to incompatible changes in the format of
the JSON file. It's now not a custom dict anymore but a dict
destination node, named ``prepare-node-join``, to configure the SSH
daemon. Paramiko is no longer necessary to configure nodes' SSH
daemons via ``gnt-node add``.
+- Draining (``gnt-cluster queue drain``) and un-draining the job queue
+ (``gnt-cluster queue undrain``) now affects all nodes in a cluster and
+ the flag is not reset after a master failover.
+- Python 2.4 has *not* been tested with this release. Using 2.6 or above
+ is recommended. 2.6 will be mandatory from the 2.8 series.
+
+
+New features
+~~~~~~~~~~~~
+
+- 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)`.
+- New ``exclusive-storage`` node parameter added, restricted to
+ nodegroup level. 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.
+- 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)`.
- A new user option, :pyeval:`rapi.RAPI_ACCESS_READ`, has been added
for RAPI users. It allows granting permissions to query for
information to a specific user without giving
a cluster from a machine by stopping all daemons, removing
certificates and ssconf files. Unless the ``--no-backup`` option is
given, copies of the certificates are made.
-- Draining (``gnt-cluster queue drain``) and un-draining the job queue
- (``gnt-cluster queue undrain``) now affects all nodes in a cluster and
- the flag is not reset after a master failover.
- Instance creations now support the use of opportunistic locking,
potentially speeding up the (parallel) creation of multiple instances.
This feature is currently only available via the :doc:`RAPI
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.
+- New experimental linux-ha resource scripts.
+- Restricted-commands support: ganeti can now be asked (via command line
+ or rapi) to perform commands on a node. These are passed via ganeti
+ RPC rather than ssh. This functionality is restricted to commands
+ specified on the ``$sysconfdir/ganeti/restricted-commands`` for security
+ reasons. The file is not copied automatically.
+
+
+Misc changes
+~~~~~~~~~~~~
+
+- Diskless instances are now externally mirrored (Issue 237). This for
+ now has only been tested in conjunction with explicit target nodes for
+ migration/failover.
- 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)
-- ``hbal`` will now exit with status 0 if, during job execution over
- LUXI, early exit has been requested and all jobs are successful;
- before, exit status 1 was used, which cannot be differentiated from
- "job error" case
+- The functionality for allocating multiple instances at once has been
+ overhauled and is now also available through :doc:`RAPI <rapi>`.
+
+Since beta2:
+
+- Fix hail to verify disk instance policies on a per-disk basis (Issue 418).
+- Fix data loss on wrong usage of ``gnt-instance move``
+- Properly export errors in confd-based job queries
+- Add ``users-setup`` tool
+- Fix iallocator protocol to report 0 as a disk size for diskless
+ instances. This avoids hail breaking when a diskless instance is
+ present.
+- Fix job queue directory permission problem that made confd job queries
+ fail. This requires running an ``ensure-dirs --full-run`` on upgrade
+ for access to archived jobs (Issue 406).
+- Limit the sizes of networks supported by ``gnt-network`` to something
+ between a ``/16`` and a ``/30`` to prevent memory bloat and crashes.
+- Fix bugs in instance disk template conversion
+- Fix GHC 7 compatibility
+- Fix ``burnin`` install path (Issue 426).
+- Allow very small disk grows (Issue 347).
+- Fix a ``ganeti-noded`` memory bloat introduced in 2.5, by making sure
+ that noded doesn't import masterd code (Issue 419).
+- Make sure the default metavg at cluster init is the same as the vg, if
+ unspecified (Issue 358).
+- Fix cleanup of partially created disks (part of Issue 416)
+
+
