+
+
+Version 2.1.0
+-------------
+
+Ganeti 2.1 brings many improvements with it. Major changes:
+
+- Added infrastructure to ease automated disk repairs
+- Added new daemon to export configuration data in a cheaper way than
+ using the remote API
+- Instance NICs can now be routed instead of being associated with a
+ networking bridge
+- Improved job locking logic to reduce impact of jobs acquiring multiple
+ locks waiting for other long-running jobs
+
+Detailed implementation details can be found in the Ganeti 2.1 design
+document.
+
+Details
+~~~~~~~
+
+- Added chroot hypervisor

+ file on nodes

+- Added dry run mode to some LUs
+- Added RAPI resources:
+
+ - ``/2/instances/[instance_name]/info``
+ - ``/2/instances/[instance_name]/replace-disks``
+ - ``/2/nodes/[node_name]/evacuate``

+
+- Added OpCodes to evacuate or migrate all instances on a node
+- Added new command to list physical volumes on nodes (``gnt-node
+ physical-volumes``) and to modify them (``gnt-node modify-volume``)
+- Added new ssconf files with master candidate IP address
+ (``ssconf_master_candidates_ips``), node primary IP address
+ (``ssconf_node_primary_ips``) and node secondary IP address
+ (``ssconf_node_secondary_ips``)
+- Added ``ganeti-confd`` and a client library to query the Ganeti
+ configuration via UDP
+- Added ability to run hooks after cluster initialization and before
+ cluster destruction
+- Added automatic mode for disk replace (``gnt-instance replace-disks
+ --auto``)
+- Added ``gnt-instance recreate-disks`` to re-create (empty) disks
+ after catastrophic data-loss
+- Added ``gnt-node repair-volume`` command to repair damanged LVM volume
+ groups
+- Added ``gnt-instance move`` command to move instances
+- Added ``gnt-cluster watcher`` command to control watcher
+- Added ``gnt-node powercycle`` command to powercycle nodes
+- Added new job status field ``lock_status``
+- Added parseable error codes to cluster verification (``gnt-cluster
+ verify --error-codes``) and made output less verbose (use
+ ``--verbose`` to restore previous behaviour)
+- Added UUIDs to the main config entities (cluster, nodes, instances)
+- Added support for OS variants
+- Added more unittests
+- Fixed critical bug in ganeti-masterd startup
+- Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
+ reinstalling an instance
+- Converted to Sphinx (http://sphinx.pocoo.org/) for documentation
+- Many documentation updates
+- Distribute hypervisor files on ``gnt-cluster redist-conf``
+- ``gnt-instance reinstall`` can now reinstall multiple instances
+- Updated many command line parameters
+- Introduced new OS API version 15
+- No longer support a default hypervisor
+- Treat virtual LVs as inexistent
+- Improved job locking logic to reduce lock contention
+- Match instance and node names case insensitively
+- Reimplemented bash completion script to be more complete
+- Improved burnin
+- Added option to specify maximum timeout on instance shutdown
+
+
+Version 2.0.4
+-------------
+
+- Fixed many wrong messages
+- Fixed a few bugs related to the locking library
+- Fixed MAC checking at instance creation time
+- Fixed a DRBD parsing bug related to gaps in /proc/drbd
+- Fixed a few issues related to signal handling in both daemons and
+ scripts
+- Fixed the example startup script provided
+- Fixed insserv dependencies in the example startup script (patch from
+ Debian)
+- Fixed handling of drained nodes in the iallocator framework
+- Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
+ #528618)
+- Fixed error related to invalid job IDs in job polling
+- Fixed job/opcode persistence on unclean master shutdown
+- Fixed handling of partial job processing after unclean master
+ shutdown
+- Fixed error reporting from LUs, previously all errors were converted
+ into execution errors
+- Fixed error reporting from burnin
+- Decreased significantly the memory usage of the job queue
+- Optimised slightly multi-job submission
+- Optimised slightly opcode loading
+- Backported the multi-job submit framework from the development
+ branch; multi-instance start and stop should be faster
+- Added script to clean archived jobs after 21 days; this will reduce
+ the size of the queue directory
+- Added some extra checks in disk size tracking
+- Added an example ethers hook script
+- Added a cluster parameter that prevents Ganeti from modifying of
+ /etc/hosts
+- Added more node information to RAPI responses
+- Added a ``gnt-job watch`` command that allows following the ouput of a
+ job
+- Added a bind-address option to ganeti-rapi
+- Added more checks to the configuration verify
+- Enhanced the burnin script such that some operations can be retried
+ automatically
+- Converted instance reinstall to multi-instance model
+
+
+Version 2.0.3
+-------------
+
+- Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
+ to allow using the pre-2.0.2 behaviour in activation, if any existing
+ instances have mismatched disk sizes in the configuration
+- Added ``gnt-cluster repair-disk-sizes`` command to check and update
+ any configuration mismatches for disk sizes
+- Added ``gnt-master cluste-failover --no-voting`` to allow master
+ failover to work on two-node clusters
+- Fixed the ``--net`` option of ``gnt-backup import``, which was
+ unusable
+- Fixed detection of OS script errors in ``gnt-backup export``
+- Fixed exit code of ``gnt-backup export``
+
+
+Version 2.0.2
+-------------
+
+- Added experimental support for stripped logical volumes; this should
+ enhance performance but comes with a higher complexity in the block
+ device handling; stripping is only enabled when passing
+ ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
+ affected even in the non-stripped mode
+- Improved resiliency against transient failures at the end of DRBD
+ resyncs, and in general of DRBD resync checks
+- Fixed a couple of issues with exports and snapshot errors
+- Fixed a couple of issues in instance listing
+- Added display of the disk size in ``gnt-instance info``
+- Fixed checking for valid OSes in instance creation
+- Fixed handling of the "vcpus" parameter in instance listing and in
+ general of invalid parameters
+- Fixed http server library, and thus RAPI, to handle invalid
+ username/password combinations correctly; this means that now they
+ report unauthorized for queries too, not only for modifications,
+ allowing earlier detect of configuration problems
+- Added a new "role" node list field, equivalent to the master/master
+ candidate/drained/offline flags combinations
+- Fixed cluster modify and changes of candidate pool size
+- Fixed cluster verify error messages for wrong files on regular nodes
+- Fixed a couple of issues with node demotion from master candidate role
+- Fixed node readd issues
+- Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
+- Added a new ``--no-voting`` option for masterfailover to fix failover
+ on two-nodes clusters when the former master node is unreachable
+- Added instance reinstall over RAPI
