Instead, ``admin_state`` is introduced, + with 3 possible values -- ``up``, ``down`` and ``offline``. + + +Version 2.5.0 rc5 +----------------- + +*(unreleased)* + +Improvements and bugfixes +~~~~~~~~~~~~~~~~~~~~~~~~~ + +- Support for kvm version 1.0, that changed the version reporting format + (from 3 to 2 digits). + + +Version 2.5.0 rc4 +----------------- + +*(Released Thu, 27 Oct 2011)* + +Incompatible/important changes and bugfixes +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +- The default of the ``/2/instances/[instance_name]/rename`` RAPI + resource's ``ip_check`` parameter changed from ``True`` to ``False`` + to match the underlying LUXI interface. +- The ``/2/nodes/[node_name]/evacuate`` RAPI resource was changed to use + body parameters, see :doc:`RAPI documentation `. The server does + not maintain backwards-compatibility as the underlying operation + changed in an incompatible way. The RAPI client can talk to old + servers, but it needs to be told so as the return value changed. +- When creating file-based instances via RAPI, the ``file_driver`` + parameter no longer defaults to ``loop`` and must be specified. +- The deprecated ``bridge`` NIC parameter is no longer supported. Use + ``link`` instead. +- Support for the undocumented and deprecated RAPI instance creation + request format version 0 has been dropped. Use version 1, supported + since Ganeti 2.1.3 and :doc:`documented `, instead. +- Pyparsing 1.4.6 or above is required, see :doc:`installation + documentation `. +- The "cluster-verify" hooks are now executed per group by the + ``OP_CLUSTER_VERIFY_GROUP`` opcode. This maintains the same behavior + if you just run ``gnt-cluster verify``, which generates one opcode per + group. +- The environment as passed to the OS scripts is cleared, and thus no + environment variables defined in the node daemon's environment will be + inherited by the scripts. +- The :doc:`iallocator ` mode ``multi-evacuate`` has been + deprecated. +- :doc:`New iallocator modes ` have been added to + support operations involving multiple node groups. +- Offline nodes are ignored when failing over an instance. + +New features +~~~~~~~~~~~~ + +- The ganeti-htools project has been merged into the ganeti-core source + tree and will be built as part of Ganeti (see :doc:`install-quick`). +- Implemented support for :doc:`shared storage `. +- Add support for disks larger than 2 TB in ``lvmstrap`` by supporting + GPT-style partition tables (requires `parted + `_). +- Added support for floppy drive and 2nd CD-ROM drive in KVM hypervisor. +- Allowed adding tags on instance creation. +- Export instance tags to hooks (``INSTANCE_TAGS``, see :doc:`hooks`) +- Allow instances to be started in a paused state, enabling the user to + see the complete console output on boot using the console. +- Added new hypervisor flag to control default reboot behaviour + (``reboot_behavior``). +- Added support for KVM keymaps (hypervisor parameter ``keymap``). +- Improved out-of-band management support: + + - Added ``gnt-node health`` command reporting the health status of + nodes. + - Added ``gnt-node power`` command to manage power status of nodes. + - Added command for emergency power-off (EPO), ``gnt-cluster epo``. + +- Instance migration can fall back to failover if instance is not + running. +- Filters can be used when listing nodes, instances, groups and locks; + see *ganeti(7)* manpage. +- Added post-execution status as variables to :doc:`hooks ` + environment. +- Instance tags are exported/imported together with the instance. +- When given an explicit job ID, ``gnt-job info`` will work for archived + jobs. +- Jobs can define dependencies on other jobs (not yet supported via + RAPI or command line, but used by internal commands and usable via + LUXI). + + - Lock monitor (``gnt-debug locks``) shows jobs waiting for + dependencies. + +- Instance failover is now available as a RAPI resource + (``/2/instances/[instance_name]/failover``). +- ``gnt-instance info`` defaults to static information if primary node + is offline. +- Opcodes have a new ``comment`` attribute. +- Added basic SPICE support to KVM hypervisor. +- ``tools/ganeti-listrunner`` allows passing of arguments to executable. + +Node group improvements +~~~~~~~~~~~~~~~~~~~~~~~ + +- ``gnt-cluster verify`` has been modified to check groups separately, + thereby improving performance. +- Node group support has been added to ``gnt-cluster verify-disks``, + which now operates per node group. +- Watcher has been changed to work better with node groups. + + - One process and state file per node group. + - Slow watcher in one group doesn't block other group's watcher. + +- Added new command, ``gnt-group evacuate``, to move all instances in a + node group to other groups. +- Added ``gnt-instance change-group`` to move an instance to another + node group. +- ``gnt-cluster command`` and ``gnt-cluster copyfile`` now support + per-group operations. +- Node groups can be tagged. +- Some operations switch from an exclusive to a shared lock as soon as + possible. +- Instance's primary and secondary nodes' groups are now available as + query fields (``pnode.group``, ``pnode.group.uuid``, ``snodes.group`` + and ``snodes.group.uuid``). + +Misc +~~~~ + +- Numerous updates to documentation and manpages. + + - :doc:`RAPI ` documentation now has detailed parameter + descriptions. + - Some opcode/job results are now also documented, see :doc:`RAPI + `. + +- A lockset's internal lock is now also visible in lock monitor. +- Log messages from job queue workers now contain information about the + opcode they're processing. +- ``gnt-instance console`` no longer requires the instance lock. +- A short delay when waiting for job changes reduces the number of LUXI + requests significantly. +- DRBD metadata volumes are overwritten with zeros during disk creation. + + +Version 2.5.0 rc3 +----------------- + +*(Released Wed, 26 Oct 2011)* + +This

least) creation of many instances in parallel +- Improved output for gnt-job info +- Removed the quiet flag on some ssh calls which prevented debugging + failures +- Improved the N+1 failure messages in cluster verify by actually + showing the memory values (needed and available) +- Increased lock attempt timeouts so that when executing long operations + (e.g. DRBD replace-disks) other jobs do not enter 'blocking acquire' + too early and thus prevent the use of the 'fair' mechanism +- Changed instance query data (``gnt-instance info``) to not acquire + locks unless needed, thus allowing its use on locked instance if only + static information is asked for +- Improved behaviour with filesystems that do not support rename on an + opened file +- Fixed the behaviour of ``prealloc_wipe_disks`` cluster parameter which + kept locks on all nodes during the wipe, which is unneeded +- Fixed ``gnt-watcher`` handling of errors during hooks execution +- Fixed bug in ``prealloc_wipe_disks`` with small disk sizes (less than + 10GiB) which caused the wipe to fail right at the end in some cases +- Fixed master IP activation when doing master failover with no-voting +- Fixed bug in ``gnt-node add --readd`` which allowed the re-adding of + the master node itself +- Fixed potential data-loss in under disk full conditions, where Ganeti + wouldn't check correctly the return code and would consider

different volume group +- Fixed error handling in the node daemon when the system libc doesn't + have major number 6 (i.e. if ``libc.so.6`` is not the actual libc) +- Fixed lock release during replace-disks, which kept cluster-wide locks + when doing disk replaces with an iallocator script +- Added check for missing bridges in cluster verify +- Handle EPIPE errors while writing to the

simply terminating +- Fixed a race condition in LUGroupAssignNodes (``gnt-group + assign-nodes``) +- Added a few more parameters to the KVM hypervisor, allowing a second + CDROM, custom disk type for CDROMs and a floppy image +- Removed redundant message in instance rename when the name is given + already as a FQDN +- Added option to ``gnt-instance recreate-disks`` to allow creating the + disks on new nodes, allowing recreation when the original instance + nodes are completely gone +- Added option when converting disk templates to DRBD to skip waiting + for the resync, in order to make the instance available sooner +- Added two new variables to the OS scripts environment (containing the + instance's nodes) +- Made the root_path and optional parameter for the xen-pvm hypervisor, + to allow use of ``pvgrub`` as bootloader +- Changed the instance memory modifications to only check out-of-memory + conditions on memory increases, and turned the secondary node warnings + into errors (they can still be overridden via ``--force``) +- Fixed the handling of a corner case when the Python installation gets + corrupted (e.g. a bad disk) while ganeti-noded is running and we try + to execute a command that doesn't exist +- Fixed a bug in ``gnt-instance move`` (LUInstanceMove) when the primary + node of the instance returned failures during instance shutdown; this + adds the option

While there were some +internal changes, the code has been mostly stabilised for the RC +release. + +Note: the dumb allocator was removed in this release, as it was not kept +up-to-date with the IAllocator protocol changes. It is recommended to +use the ``hail`` command from the ganeti-htools package. + +Note: the 2.4 and up versions of Ganeti are not compatible with the +0.2.x branch of ganeti-htools.

Some new features, and some +fixes/small improvements/cleanups. + +Significant features +~~~~~~~~~~~~~~~~~~~~ + +The node deamon now tries to mlock itself into memory, unless the +``--no-mlock`` flag is passed. It also doesn't fail if it can't write +its logs, and falls back to console logging. This allows emergency +features such as ``gnt-node powercycle`` to work even in the event of a +broken node disk (tested offlining the disk hosting the node's +filesystem and dropping its memory caches; don't try this at home) + +KVM: add vhost-net acceleration support. It can be tested with a new +enough version of the kernel and of qemu-kvm. + +KVM: Add instance chrooting feature. If you use privilege dropping for +your VMs you can also now force them to chroot to an empty directory, +before starting the emulated guest. + +KVM: Add maximum migration bandwith and maximum downtime tweaking +support (requires a new-enough version of qemu-kvm). + +Cluster verify will now warn if the master node doesn't have the master +ip configured on it. + +Add a new (incompatible) instance creation request format to RAPI which +supports all parameters (previously only a subset was supported, and it +wasn't possible to extend the old format to accomodate all the new +features. The old format is still supported, and a client can check for +this feature, before using it, by checking for its presence in the +``features`` RAPI resource. + +Now with ancient latin support. Try it passing the ``--roman`` option to +``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list`` +(requires the python-roman module to be installed, in order to work). + +Other changes +~~~~~~~~~~~~~ + +As usual many internal code refactorings, documentation updates, and +such. Among others: + + - Lots of improvements and cleanups to the experimental Remote API + (RAPI) client library. + - A new unit test suite for the core daemon libraries. + - A fix to creating missing directories makes sure the umask is not + applied anymore. This enforces the same directory permissions + everywhere. + - Better handling terminating daemons with ctrl+c (used when running + them in debugging mode). + - Fix a race condition in live migrating a KVM instance, when stat() + on the old proc status file returned EINVAL, which is an unexpected + value. + - Fixed manpage checking with newer man and utf-8 charachters. But now + you need the en_US.UTF-8 locale enabled to build Ganeti from git. + + +Version 2.1.2.1 +--------------- + +*(Released Fri, 7 May 2010)* + +Fix a bug which prevented untagged KVM instances from starting. + + +Version 2.1.2 +------------- + +*(Released Fri, 7 May 2010)* + +Another release with a long development cycle, during which many +different features were added. + +Significant features +~~~~~~~~~~~~~~~~~~~~ + +The KVM hypervisor now can run the individual instances as non-root, to +reduce the impact of a VM being hijacked due to bugs in the +hypervisor. It is possible to run all instances as a single (non-root) +user, to manually specify a user for each instance, or to dynamically +allocate a user out of a cluster-wide pool to each instance, with the +guarantee that no two instances will run under the same user ID on any +given node. + +An experimental RAPI client library, that can be used standalone +(without the other Ganeti libraries), is provided in the source tree as +``lib/rapi/client.py``. Note this client might change its interface in +the future, as we iterate on its capabilities. + +A new command, ``gnt-cluster renew-crypto`` has been added to easily +replace the cluster's certificates and crypto keys. This might help in +case they have been compromised, or have simply expired. + +A new disk option for instance creation has been added that allows one +to "adopt" currently existing logical volumes, with data +preservation. This should allow easier migration to Ganeti from +unmanaged (or managed via other software) instances. + +Another disk improvement is the possibility to convert between redundant +(DRBD) and plain (LVM) disk configuration for an instance. This should +allow better scalability (starting with one node and growing the +cluster, or shrinking a two-node cluster to one node). + +A new feature that could help with automated node failovers has been +implemented: if a node sees itself as offline (by querying the master +candidates), it will try to shutdown (hard) all instances and any active +DRBD devices. This reduces the risk of duplicate instances if an +external script automatically failovers the instances on such nodes. To +enable this, the cluster parameter ``maintain_node_health`` should be +enabled; in the future this option (per the name) will enable other +automatic maintenance features. + +Instance export/import now will reuse the original instance +specifications for all parameters; that means exporting an instance, +deleting it and the importing it back should give an almost identical +instance. Note that the default import behaviour has changed from +before, where it created only one NIC; now it recreates the original +number of NICs. + +Cluster verify has added a few new checks: SSL certificates validity, +/etc/hosts consistency across the cluster, etc. + +Other changes +~~~~~~~~~~~~~ + +As usual, many internal changes were done, documentation fixes, +etc. Among others: + +- Fixed cluster initialization with disabled cluster storage (regression + introduced in 2.1.1) +- File-based storage supports growing the disks +- Fixed behaviour of node role changes +- Fixed cluster verify for some corner cases, plus a general rewrite of + cluster verify to allow future extension with more checks +- Fixed log spamming by watcher and node daemon (regression introduced + in 2.1.1) +- Fixed possible validation issues when changing the list of enabled + hypervisors +- Fixed cleanup of /etc/hosts during node removal +- Fixed RAPI response for invalid methods +- Fixed bug with hashed passwords in ``ganeti-rapi`` daemon +- Multiple small improvements to the KVM hypervisor (VNC usage, booting + from ide disks, etc.) +- Allow OS changes without re-installation (to record a changed OS + outside of Ganeti, or to allow OS renames) +- Allow instance creation without OS installation (useful for example if + the OS will be installed manually, or restored from a backup not in + Ganeti format) +- Implemented option to make cluster ``copyfile`` use the replication + network +- Added list of enabled hypervisors to ssconf (possibly useful for + external scripts) +- Added a new tool (``tools/cfgupgrade12``) that allows upgrading from + 1.2 clusters +- A partial form of node re-IP is possible via node readd, which now + allows changed node primary IP +- Command line utilities now show an informational message if the job is + waiting for a lock +- The logs of the master daemon now show the PID/UID/GID of the + connected client + + +Version 2.1.1 +------------- + +*(Released Fri, 12 Mar 2010)* + +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 +------------- + +*(Released Tue, 2 Mar 2010)* + +Ganeti 2.1 brings many improvements with it.
