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. +- Support for KVM version 1.0, which changed the version reporting format + from 3 to 2 digits. +- ``Makefile`` is now compatible with Automake 1.11.2 +- Includes all bugfixes made in the 2.4 series +New features +~~~~~~~~~~~~ -Version 2.4.3 +- 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). + + -

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. + + -
