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. You need to upgrade to +ganeti-htools-0.3.0 (or later). + +Regressions fixed from 2.3 +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +- Fixed the ``gnt-cluster verify-disks`` command +- Made ``gnt-cluster verify-disks`` work in parallel (as opposed to + serially on nodes) +- Fixed disk adoption breakage +- Fixed wrong headers in instance listing for field aliases + +Other bugs fixed +~~~~~~~~~~~~~~~~ + +- Fixed corner case in KVM handling of NICs +- Fixed many cases of wrong handling of non-vm_capable nodes +- Fixed a bug where a missing instance symlink was not possible to + recreate with any ``gnt-*`` command (now ``gnt-instance + activate-disks`` does it) +- Fixed the volume group name as reported by ``gnt-cluster + verify-disks`` +- Increased timeouts for the import-export code, hopefully leading to + fewer aborts due network or instance timeouts +- Fixed bug in ``gnt-node list-storage`` +- Fixed bug where not all daemons were started on cluster + initialisation, but only at the first watcher run +- Fixed many bugs in the OOB implementation +- Fixed watcher behaviour in presence of instances with offline + secondaries +- Fixed instance list output for instances running on the wrong node +- a few fixes to the cluster-merge tool, but it still cannot merge + multi-node groups (currently it is not recommended to use this tool) + + +Improvements +~~~~~~~~~~~~ + +- Improved network configuration for the KVM hypervisor +- Added e1000 as a supported NIC for Xen-HVM +- Improved the lvmstrap tool to also be able to use partitions, as + opposed to full disks +- Improved speed of disk wiping (the cluster parameter + ``prealloc_wipe_disks``, so that it has a low impact on the total time + of instance creations +- Added documentation for the OS parameters +- Changed ``gnt-instance deactivate-disks`` so that it can work if the + hypervisor is not responding +- Added display of blacklisted and hidden OS information in + ``gnt-cluster info`` +- Extended ``gnt-cluster verify`` to also validate hypervisor, backend, + NIC and node parameters, which might create problems with currently + invalid (but undetected) configuration files, but prevents validation + failures when unrelated parameters are modified +- Changed cluster initialisation to wait for the master daemon to become + available +- Expanded the RAPI interface: + + - Added config redistribution resource + - Added activation/deactivation of instance disks + - Added export of console information + +- Implemented log file reopening on SIGHUP, which allows using + logrotate(8) for the Ganeti log files +- Added a basic OOB helper script as an example + + +Version 2.4.0 beta1 +------------------- + +*(Released Fri, 14 Jan 2011)* + +User-visible +~~~~~~~~~~~~ + +- Fixed timezone issues when formatting timestamps +- Added support for node groups, available via ``gnt-group`` and other + commands +- Added out-of-band framework and management, see :doc:`design + document ` +- Removed support for roman numbers from ``gnt-node list`` and + ``gnt-instance list``. +- Allowed modification of master network interface via ``gnt-cluster + modify --master-netdev`` +- Accept offline secondaries while shutting down instance disks +- Added ``blockdev_prefix`` parameter to Xen PVM and HVM hypervisors +- Added support for multiple LVM volume groups +- Avoid sorting nodes for ``gnt-node list`` if specific nodes are + requested +- Added commands to list available fields: + + - ``gnt-node list-fields`` + - ``gnt-group list-fields`` + - ``gnt-instance list-fields`` + +- Updated documentation and man pages + +Integration +~~~~~~~~~~~ + +- Moved ``rapi_users`` file into separate directory, now named + ``…/ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a + symlink +- Added new tool for running commands on many machines, + ``tools/ganeti-listrunner`` +- Implemented more verbose result in ``OpInstanceConsole`` opcode, also + improving the ``gnt-instance console`` output +- Allowed customisation of disk index separator at ``configure`` time +- Export node group allocation policy to :doc:`iallocator ` +- Added support for non-partitioned md disks in ``lvmstrap`` +- Added script to gracefully power off KVM instances +- Split ``utils`` module into smaller parts +- Changed query operations to return more detailed information, e.g. + whether an information is unavailable due to an offline node.
