+News
+====
+
+
+Version 2.1.1
+-------------
+
+During the 2.1.0 long release candidate cycle, a lot of improvements and
+changes have accumulated with were released later as 2.1.1.
+
+Major changes
+~~~~~~~~~~~~~
+
+The node evacuate command (``gnt-node evacuate``) was significantly
+rewritten, and as such the IAllocator protocol was changed - a new
+request type has been added. This unfortunate change during a stable
+series is designed to improve performance of node evacuations; on
+clusters with more than about five nodes and which are well-balanced,
+evacuation should proceed in parallel for all instances of the node
+being evacuated. As such, any existing IAllocator scripts need to be
+updated, otherwise the above command will fail due to the unknown
+request. The provided "dumb" allocator has not been updated; but the
+ganeti-htools package supports the new protocol since version 0.2.4.
+
+Another important change is increased validation of node and instance
+names. This might create problems in special cases, if invalid host
+names are being used.
+
+Also, a new layer of hypervisor parameters has been added, that sits at
+OS level between the cluster defaults and the instance ones. This allows
+customisation of virtualization parameters depending on the installed
+OS. For example instances with OS 'X' may have a different KVM kernel
+(or any other parameter) than the cluster defaults. This is intended to
+help managing a multiple OSes on the same cluster, without manual
+modification of each instance's parameters.
+
+A tool for merging clusters, ``cluster-merge``, has been added in the
+tools sub-directory.
+
+Bug fixes
+~~~~~~~~~
+
+- Improved the int/float conversions that should make the code more
+ robust in face of errors from the node daemons
+- Fixed the remove node code in case of internal configuration errors
+- Fixed the node daemon behaviour in face of inconsistent queue
+ directory (e.g. read-only file-system where we can't open the files
+ read-write, etc.)
+- Fixed the behaviour of gnt-node modify for master candidate demotion;
+ now it either aborts cleanly or, if given the new “auto_promote”
+ parameter, will automatically promote other nodes as needed
+- Fixed compatibility with (unreleased yet) Python 2.6.5 that would
+ completely prevent Ganeti from working
+- Fixed bug for instance export when not all disks were successfully
+ exported
+- Fixed behaviour of node add when the new node is slow in starting up
+ the node daemon
+- Fixed handling of signals in the LUXI client, which should improve
+ behaviour of command-line scripts
+- Added checks for invalid node/instance names in the configuration (now
+ flagged during cluster verify)
+- Fixed watcher behaviour for disk activation errors
+- Fixed two potentially endless loops in http library, which led to the
+ RAPI daemon hanging and consuming 100% CPU in some cases
+- Fixed bug in RAPI daemon related to hashed passwords
+- Fixed bug for unintended qemu-level bridging of multi-NIC KVM
+ instances
+- Enhanced compatibility with non-Debian OSes, but not using absolute
+ path in some commands and allowing customisation of the ssh
+ configuration directory
+- Fixed possible future issue with new Python versions by abiding to the
+ proper use of ``__slots__`` attribute on classes
+- Added checks that should prevent directory traversal attacks
+- Many documentation fixes based on feedback from users
+
+New features
+~~~~~~~~~~~~
+
+- Added an “early_release” more for instance replace disks and node
+ evacuate, where we release locks earlier and thus allow higher
+ parallelism within the cluster
+- Added watcher hooks, intended to allow the watcher to restart other
+ daemons (e.g. from the ganeti-nbma project), but they can be used of
+ course for any other purpose
+- Added a compile-time disable for DRBD barriers, to increase
+ performance if the administrator trusts the power supply or the
+ storage system to not lose writes
+- Added the option of using syslog for logging instead of, or in
+ addition to, Ganeti's own log files
+- Removed boot restriction for paravirtual NICs for KVM, recent versions
+ can indeed boot from a paravirtual NIC
+- Added a generic debug level for many operations; while this is not
+ used widely yet, it allows one to pass the debug value all the way to
+ the OS scripts
+- Enhanced the hooks environment for instance moves (failovers,
+ migrations) where the primary/secondary nodes changed during the
+ operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
+- Enhanced data validations for many user-supplied values; one important
+ item is the restrictions imposed on instance and node names, which
+ might reject some (invalid) host names
+- Add a configure-time option to disable file-based storage, if it's not
+ needed; this allows greater security separation between the master
+ node and the other nodes from the point of view of the inter-node RPC
+ protocol
+- Added user notification in interactive tools if job is waiting in the
+ job queue or trying to acquire locks
+- Added log messages when a job is waiting for locks
+- Added filtering by node tags in instance operations which admit
+ multiple instances (start, stop, reboot, reinstall)
+- Added a new tool for cluster mergers, ``cluster-merge``
+- Parameters from command line which are of the form ``a=b,c=d`` can now
+ use backslash escapes to pass in values which contain commas,
+ e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
+ ``b,c``
+- For KVM, the instance name is the first parameter passed to KVM, so
+ that it's more visible in the process list
+
+
+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
+
+In-depth implementation details can be found in the Ganeti 2.1 design
+document.

+- Improve safety of the code in some error paths
+- Improve data validation in the master of values returned from nodes
+
+

+ allows local and remote execution of arbitrary executables
+- Fix failure of gnt-node list during instance removal
+- Ship the RAPI documentation in the archive
+
+

+-------------
+
+- Fixed many wrong messages

+- 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 a bind-address option to ganeti-rapi
+- Added more checks to the configuration verify

+ 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
+
+
+Version 2.0.1
+-------------
+
+- added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
+ allow re-adding the start in single-user option (regression from 1.2)
+- the watcher writes the instance status to a file, to allow monitoring
+ to report the instance status (from the master) based on cached
+ results of the watcher's queries; while this can get stale if the
+ watcher is being locked due to other work on the cluster, this is
+ still an improvement
+- 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)
+- 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
+- rapi uses queries for tags instead of jobs (for less job traffic), and
+ for cluster tags it won't talk to masterd at all but read them from
+ ssconf
+- a couple of error handling fixes in RAPI
+- drbd handling: improved the error handling of inconsistent disks after
+ resync to reduce the frequency of "there are some degraded disks for
+ this instance" messages
+- fixed a bug in live migration when DRBD doesn't want to reconnect (the
+ error handling path called a wrong function name)
+
+
+Version 2.0.0 final
+-------------------
+
+- no changes from rc5
+
+
+Version 2.0 release candidate 5
+-------------------------------
+
+- fix a couple of bugs (validation, argument checks)
+- fix ``gnt-cluster getmaster`` on non-master nodes (regression)
+- some small improvements to RAPI and IAllocator
+- make watcher automatically start the master daemon if down
+
+
+Version 2.0 release candidate 4
+-------------------------------
+
+- change the OS list to not require locks; this helps with big clusters
+- fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
+ volume group is broken
+- ``gnt-instance info``, without any arguments, doesn't run for all
+ instances anymore; either pass ``--all`` or pass the desired
+ instances; this helps against mistakes on big clusters where listing
+ the information for all instances takes a long time
+- miscellaneous doc and man pages fixes
+
+
+Version 2.0 release candidate 3
+-------------------------------
+
+- Change the internal locking model of some ``gnt-node`` commands, in
+ order to reduce contention (and blocking of master daemon) when
+ batching many creation/reinstall jobs
+- Fixes to Xen soft reboot
+- No longer build documentation at build time, instead distribute it in
+ the archive, in order to reduce the need for the whole docbook/rst
+ toolchains
+
+
+Version 2.0 release candidate 2
+-------------------------------
+
+- Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
+- Fix watcher startup sequence, improves the behaviour of busy clusters
+- Some other fixes in ``gnt-cluster verify``, ``gnt-instance
+ replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
+ bind address and other places
+- Some documentation fixes and updates
+
+
+Version 2.0 release candidate 1
+-------------------------------
+
+- More documentation updates, now all docs should be more-or-less
+ up-to-date
+- A couple of small fixes (mixed hypervisor clusters, offline nodes,
+ etc.)
+- Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
+ and KVM)
+- Fix an issue related to $libdir/run/ganeti and cluster creation
+
+
+Version 2.0 beta 2
+------------------
+
+- Xen PVM and KVM have switched the default value for the instance root
+ disk to the first partition on the first drive, instead of the whole
+ drive; this means that the OS installation scripts must be changed
+ accordingly
+- Man pages have been updated
+- RAPI has been switched by default to HTTPS, and the exported functions
+ should all work correctly
+- RAPI v1 has been removed
+- Many improvements to the KVM hypervisor
+- Block device errors are now better reported
+- Many other bugfixes and small improvements
+
+
+Version 2.0 beta 1
+------------------
+
+- Version 2 is a general rewrite of the code and therefore the
+ differences are too many to list, see the design document for 2.0 in
+ the ``doc/`` subdirectory for more details
+- In this beta version there is not yet a migration path from 1.2 (there
+ will be one in the final 2.0 release)
+- A few significant changes are:
+
+ - 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
+ - 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)
+ - DRBD devices are using statically allocated minor numbers, which
+ will be assigned to existing instances during the migration process
+ - there is support for both Xen PVM and Xen HVM instances running on
+ the same cluster
+ - KVM virtualization is supported too
+ - file-based storage has been implemented, which means that it is
+ possible to run the cluster without LVM and DRBD storage, for
+ example using a shared filesystem exported from shared storage (and
+ still have live migration)
+
+
+Version 1.2.7
+-------------
+
+- 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)
+- Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
+- Improved version of batcher:
+
+ - state file support
+ - instance mac address support
+ - support for HVM clusters/instances
+
+- Add an option to show the number of cpu sockets and nodes in
+ ``gnt-node list``
+- Support OSes that handle more than one version of the OS api (but do
+ not change the current API in any other way)
+- Fix ``gnt-node migrate``
+- ``gnt-debug`` man page
+- Fixes various more typos and small issues
+- Increase disk resync maximum speed to 60MB/s (from 30MB/s)
+
+
+Version 1.2.6
+-------------
+
+- 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.
+- 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.
+- when changing the memory amount on instance modify a check has been
+ added that the instance will be able to start. also warnings are
+ emitted if the instance will not be able to fail over, if auto_balance
+ is true.
+- documentation fixes
+- sync fields between ``gnt-instance list/modify/add/import``
+- fix a race condition in drbd when the sync speed was set after giving
+ the device a remote peer.
+
+
+Version 1.2.5
+-------------
+
+- note: the allowed size and number of tags per object were reduced
+- fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
+- fixed twisted 8.x compatibility
+- fixed ``gnt-instance replace-disks`` with iallocator
+- add TCP keepalives on twisted connections to detect restarted nodes
+- disk increase support, see ``gnt-instance grow-disk``
+- implement bulk node/instance query for RAPI
+- add tags in node/instance listing (optional)
+- experimental migration (and live migration) support, read the man page
+ for ``gnt-instance migrate``
+- the ``ganeti-watcher`` logs are now timestamped, and the watcher also
+ has some small improvements in handling its state file
+
+
+Version 1.2.4
+-------------
+
+- Experimental readonly, REST-based remote API implementation;
+ automatically started on master node, TCP port 5080, if enabled by
+ ``--enable-rapi`` parameter to configure script.
+- Instance allocator support. Add and import instance accept a
+ ``--iallocator`` parameter, and call that instance allocator to decide
+ which node to use for the instance. The iallocator document describes
+ what's expected from an allocator script.
+- ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
+ ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
+ node is lost there is still enough memory to fail over the instances
+ that reside on it.
+- ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
+ ``gnt-cluster verify``, to check for site-specific compliance. All the
+ hooks will run, and their output, if any, will be displayed. Any
+ failing hook will make the verification return an error value.
+- ``gnt-cluster verify`` now checks that its peers are reachable on the
+ primary and secondary interfaces
+- ``gnt-node add`` now supports the ``--readd`` option, to readd a node
+ that is still declared as part of the cluster and has failed.
+- ``gnt-* list`` commands now accept a new ``-o +field`` way of
+ specifying output fields, that just adds the chosen fields to the
+ default ones.
+- ``gnt-backup`` now has a new ``remove`` command to delete an existing
+ export from the filesystem.
+- New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
+ have been added. Using them you can enable/disable acpi and pae
+ support, and specify a path for a cd image to be exported to the
+ instance. These parameters as the name suggest only work on HVM
+ clusters.
+- When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
+ PAE support will be set to the previously hardcoded values, but the
+ (previously hardcoded) path to the CDROM ISO image will be unset and
+ if required, needs to be set manually with ``gnt-instance modify``
+ after the upgrade.
+- The address to which an instance's VNC console is bound is now
+ selectable per-instance, rather than being cluster wide. Of course
+ this only applies to instances controlled via VNC, so currently just
+ applies to HVM clusters.
+
+
+Version 1.2.3
+-------------
+
+- more tweaks to the disk activation code (especially helpful for DRBD)
+- change the default ``gnt-instance list`` output format, now there is
+ one combined status field (see the manpage for the exact values this
+ field will have)
+- some more fixes for the mac export to hooks change
+- make Ganeti not break with DRBD 8.2.x (which changed the version
+ format in ``/proc/drbd``) (issue 24)
+- add an upgrade tool from "remote_raid1" disk template to "drbd" disk
+ template, allowing migration from DRBD0.7+MD to DRBD8
+
+
+Version 1.2.2
+-------------
+
+- fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
+ support (issue 23)
+- add command aliases infrastructure and a few aliases
+- allow listing of VCPUs in the ``gnt-instance list`` and improve the
+ man pages and the ``--help`` option of ``gnt-node
+ list``/``gnt-instance list``
+- fix ``gnt-backup list`` with down nodes (issue 21)
+- change the tools location (move from $pkgdatadir to $pkglibdir/tools)
+- fix the dist archive and add a check for including svn/git files in
+ the future
+- some developer-related changes: improve the burnin and the QA suite,
+ add an upload script for testing during development
+
+
+Version 1.2.1
+-------------
+
+- experimental HVM support, read the install document, section
+ "Initializing the cluster"
+- allow for the PVM hypervisor per-instance kernel and initrd paths
+- add a new command ``gnt-cluster verify-disks`` which uses a new
+ algorithm to improve the reconnection of the DRBD pairs if the device
+ on the secondary node has gone away
+- make logical volume code auto-activate LVs at disk activation time
+- slightly improve the speed of activating disks
+- allow specification of the MAC address at instance creation time, and
+ changing it later via ``gnt-instance modify``
+- fix handling of external commands that generate lots of output on
+ stderr
+- update documentation with regard to minimum version of DRBD8 supported
+
+
+Version 1.2.0
+-------------
+
+- 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
+
+
