+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.

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-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 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``
- 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
+- 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
+- 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 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
- the watcher now also restarts the node daemon and the rapi daemon if
they died
- fixed the watcher to handle full and drained queue cases
-- hooks export more instance data in the environment, which helps if hook
- scripts need to take action based on the instance's properties (no
- longer need to query back into ganeti)
+- hooks export more instance data in the environment, which helps if
+ hook scripts need to take action based on the instance's properties
+ (no longer need to query back into ganeti)
- instance failovers when the instance is stopped do not check for free
RAM, so that failing over a stopped instance is possible in low memory
situations
- all commands are executed by a daemon (``ganeti-masterd``) and the
various ``gnt-*`` commands are just front-ends to it
- - all the commands are entered into, and executed from a job queue, see
- the ``gnt-job(8)`` manpage
- - the RAPI daemon supports read-write operations, secured by basic HTTP
- authentication on top of HTTPS
+ - all the commands are entered into, and executed from a job queue,
+ see the ``gnt-job(8)`` manpage
+ - the RAPI daemon supports read-write operations, secured by basic
+ HTTP authentication on top of HTTPS
- DRBD version 0.7 support has been removed, DRBD 8 is the only
supported version (when migrating from Ganeti 1.2 to 2.0, you need
to migrate to DRBD 8 first while still running Ganeti 1.2)
- Change the default reboot type in ``gnt-instance reboot`` to "hard"
- Reuse the old instance mac address by default on instance import, if
the instance name is the same.
-- Handle situations in which the node info rpc returns incomplete results
- (issue 46)
+- Handle situations in which the node info rpc returns incomplete
+ results (issue 46)
- Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
- Improved version of batcher:
- new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
type of disk exported to fully virtualized instances.
- provide access to the serial console of HVM instances
-- instance auto_balance flag, set by default. If turned off it will avoid
- warnings on cluster verify if there is not enough memory to fail over
- an instance. in the future it will prevent automatically failing it
- over when we will support that.
+- instance auto_balance flag, set by default. If turned off it will
+ avoid warnings on cluster verify if there is not enough memory to fail
+ over an instance. in the future it will prevent automatically failing
+ it over when we will support that.
- batcher tool for instance creation, see ``tools/README.batcher``
- ``gnt-instance reinstall --select-os`` to interactively select a new
operating system when reinstalling an instance.
Version 1.2.0
-------------
-- Log the ``xm create`` output to the node daemon log on failure (to help
- diagnosing the error)
+- Log the ``xm create`` output to the node daemon log on failure (to
+ help diagnosing the error)
- In debug mode, log all external commands output if failed to the logs
- Change parsing of lvm commands to ignore stderr
reboots
- Removed dependency on debian's patched fping that uses the
non-standard ``-S`` option
-- Now the OS definitions are searched for in multiple, configurable paths
- (easier for distros to package)
+- Now the OS definitions are searched for in multiple, configurable
+ paths (easier for distros to package)
- Some changes to the hooks infrastructure (especially the new
post-configuration update hook)
- Other small bugfixes
