This lead to incompatible changes in the format of + the JSON file. It's now not a custom dict anymore but a dict + compatible with the ``OpInstanceCreate`` opcode. +- Parent directories for file storage need to be listed in + ``$sysconfdir/ganeti/file-storage-paths`` now. ``cfgupgrade`` will + write the file automatically based on old configuration values, but it + can not distribute it across all nodes and the file contents should be + verified. Use ``gnt-cluster copyfile + $sysconfdir/ganeti/file-storage-paths`` once the cluster has been + upgraded. The reason for requiring this list of paths now is that + before it would have been possible to inject new paths via RPC, + allowing files to be created in arbitrary locations. The RPC protocol + is protected using SSL/X.509 certificates, but as a design principle + Ganeti does not permit arbitrary paths to be passed. +- The parsing of the variants file for OSes (see + :manpage:`ganeti-os-interface(7)`) has been slightly changed: now empty + lines and comment lines (starting with ``#``) are ignored for better + readability. +- The ``setup-ssh`` tool added in Ganeti 2.2 has been replaced and is no + longer available. ``gnt-node add`` now invokes a new tool on the + destination node, named ``prepare-node-join``, to configure the SSH + daemon. Paramiko is no longer necessary to configure nodes' SSH + daemons via ``gnt-node add``. +- A new user option, :pyeval:`rapi.RAPI_ACCESS_READ`, has been added + for RAPI users. It allows granting permissions to query for + information to a specific user without giving + :pyeval:`rapi.RAPI_ACCESS_WRITE` permissions. +- A new tool named ``node-cleanup`` has been added. It cleans remains of + a cluster from a machine by stopping all daemons, removing + certificates and ssconf files. Unless the ``--no-backup`` option is + given, copies of the certificates are made. +- Draining (``gnt-cluster queue drain``) and un-draining the job queue + (``gnt-cluster queue undrain``) now affects all nodes in a cluster and + the flag is not reset after a master failover. +- Instance creations now support the use of opportunistic locking, + potentially speeding up the (parallel) creation of multiple instances. + This feature is currently only available via the :doc:`RAPI + ` interface and when an instance allocator is used. If the + ``opportunistic_locking`` parameter is set the opcode will try to + acquire as many locks as possible, but will not wait for any locks + held by other opcodes. If the not enough resources can be found to + allocate the instance, the temporary error code + :pyeval:`errors.ECODE_TEMP_NORES` is returned. The operation can be + retried thereafter, with or without opportunistic locking. +- Man pages can now be included when the documentation is built, in + which case the output is in ``doc/man-html``. The configure-time + option is ``--enable-manpages-in-doc``. Sphinx 1.0 or higher is + required. +- A new htool called ``hroller`` helps scheduling parallel shutdown of + nodes on clusters where all instances are shut down, but without ever + rebooting both primary and secondary node for an instance at the same + time. +- Queries not needing locks or RPC access to the node can now be + performed by the confd daemon, making them independent from jobs, and + thus faster to execute. This is selectable at configure time. +- The KVM hypervisor has been updated with many new hypervisor + parameters, including a generic one for passing arbitrary command line + values. See a complete list in :manpage:`gnt-instance(8)`. +- A new tool, called ``mon-collector``, is the stand-alone executor of + the data collectors for a monitoring system. As of this version, it + just includes the DRBD data collector, that can be executed by calling + ``mon-collector`` using the ``drbd`` parameter. See + :manpage:`mon-collector(7)`. +- New ``exclusive-storage`` node parameter added. When it's set to true, + physical disks are assigned in an exclusive fashion to instances, as + documented in :doc:`Partitioned Ganeti `. + Currently, only instances using the ``plain`` disk template are + supported. +- New network management functionality to support automatic allocation + of IP addresses and managing of network parameters. See + :manpage:`gnt-network(8)` for more details. +- New external storage backend, to allow managing arbitrary storage + systems external to the cluster. See + :manpage:`ganeti-extstorage-interface(7)`. +- Instance renames of LVM-based instances will now update the LV tags + (which can be used to recover the instance-to-LV mapping in case of + emergencies) + + +Version 2.6.2 +------------- + +*(Released Fri, 21 Dec 2012)* + +Important behaviour change: hbal won't rebalance anymore instances which +have the ``auto_balance`` attribute set to false. This was the intention +all along, but until now it only skipped those from the N+1 memory +reservation (DRBD-specific). + +A significant number of bug fixes in this release: + +- Fixed disk adoption interaction with ipolicy checks. +- Fixed networking issues when instances are started, stopped or + migrated, by forcing the tap device's MAC prefix to "fe" (issue 217). +- Fixed the warning in cluster verify for shared storage instances not + being redundant. +- Fixed removal of storage directory on shared file storage (issue 262). +- Fixed validation of LVM volume group name in OpClusterSetParams + (``gnt-cluster modify``) (issue 285). +- Fixed runtime memory increases (``gnt-instance modify -m``). +- Fixed live migration under Xen's ``xl`` mode. +- Fixed ``gnt-instance console`` with ``xl``. +- Fixed building with newer Haskell compiler/libraries. +- Fixed PID file writing in Haskell daemons (confd); this prevents + restart issues if confd was launched manually (outside of + ``daemon-util``) while another copy of it was running +- Fixed a type error when doing live migrations with KVM (issue 297) and + the error messages for failing migrations have been improved. +- Fixed opcode validation for the out-of-band commands (``gnt-node + power``). +- Fixed a type error when unsetting OS hypervisor parameters (issue + 311); now it's possible to unset all OS-specific hypervisor + parameters. +- Fixed the ``dry-run`` mode for many operations: verification of + results was over-zealous but didn't take into account the ``dry-run`` + operation, resulting in "wrong" failures. +- Fixed bash completion in ``gnt-job list`` when the job queue has + hundreds of entries; especially with older ``bash`` versions, this + results in significant CPU usage. + +And lastly, a few other improvements have been made: + +- Added option to force master-failover without voting (issue 282). +- Clarified error message on lock conflict (issue 287). +- Logging of newly submitted jobs has been improved (issue 290). +- Hostname checks have been made uniform between instance rename and + create (issue 291). +- The ``--submit`` option is now supported by ``gnt-debug delay``. +- Shutting down the master daemon by sending SIGTERM now stops it from + processing jobs waiting for locks; instead, those jobs will be started + once again after the master daemon is started the next time (issue + 296). +- Support for Xen's ``xl`` program has been improved (besides the fixes + above). +- Reduced logging noise in the Haskell confd daemon (only show one log + entry for each config reload, instead of two). +- Several man page updates and typo fixes. + + +Version 2.6.1 +------------- + +*(Released Fri, 12 Oct 2012)* + +A small bugfix release. Among the bugs fixed: + +- Fixed double use of ``PRIORITY_OPT`` in ``gnt-node migrate``, that + made the command unusable. +- Commands that issue many jobs don't fail anymore just because some jobs + take so long that other jobs are archived. +- Failures during ``gnt-instance reinstall`` are reflected by the exit + status. +- Issue 190 fixed. Check for DRBD in cluster verify is enabled only when + DRBD is enabled. +- When ``always_failover`` is set, ``--allow-failover`` is not required + in migrate commands anymore. +- ``bash_completion`` works even if extglob is disabled. +- Fixed bug with locks that made failover for RDB-based instances fail. +- Fixed bug in non-mirrored instance allocation that made Ganeti choose + a random node instead of one based on the allocator metric. +- Support for newer versions of pylint and pep8. +- Hail doesn't fail anymore when trying to add an instance of type + ``file``, ``sharedfile`` or ``rbd``. +- Added new Makefile target to rebuild the whole distribution, so that + all files are included. + + Version 2.6.0 ------------- @@ -563,7 +736,7 @@ New features - 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. + see :manpage:`ganeti(7)` manpage. - Added post-execution status as variables to :doc:`hooks ` environment. - Instance tags are exported/imported together with the instance.
