-Version 2.7.0 beta1
+Version 2.7.0 beta3
-------------------
-*(unreleased)*
+*(Released Mon, 22 Apr 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
<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.
+- 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 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)
+
+
+Version 2.7.0 beta2
+-------------------
+
+*(Released Tue, 2 Apr 2013)*
+
+This was the second beta release of the 2.7 series. Since beta1:
+
+- Networks no longer have a "type" slot, since this information was
+ unused in Ganeti: instead of it tags should be used.
+- The rapi client now has a ``target_node`` option to MigrateInstance.
+- Fix early exit return code for hbal (Issue 386).
+- Fix ``gnt-instance migrate/failover -n`` (Issue 396).
+- Fix ``rbd showmapped`` output parsing (Issue 312).
+- Networks are now referenced indexed by UUID, rather than name. This
+ will require running cfgupgrade, from 2.7.0beta1, if networks are in
+ use.
+- The OS environment now includes network information.
+- Deleting of a network is now disallowed if any instance nic is using
+ it, to prevent dangling references.
+- External storage is now documented in man pages.
+- The exclusive_storage flag can now only be set at nodegroup level.
+- Hbal can now submit an explicit priority with its jobs.
+- Many network related locking fixes.
+- Bump up the required pylint version to 0.25.1.
+- Fix the ``no_remember`` option in RAPI client.
+- Many ipolicy related tests, qa, and fixes.
+- Many documentation improvements and fixes.
+- Fix building with ``--disable-file-storage``.
+- Fix ``-q`` option in htools, which was broken if passed more than
+ once.
+- Some haskell/python interaction improvements and fixes.
+- Fix iallocator in case of missing LVM storage.
+- Fix confd config load in case of ``--no-lvm-storage``.
+- The confd/query functionality is now mentioned in the security
+ documentation.
