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 βauto_promoteβ + 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 βearly_releaseβ 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 ------------- diff --git a/configure.ac b/configure.ac index 11a96d673ae567aa7fdb163a952efcfec760f24c..393920b008a01064feb42694fcbe77e048f5922c 100644 --- a/configure.ac +++ b/configure.ac @@ -1,7 +1,7 @@ # Configure script for Ganeti m4_define([gnt_version_major], [2]) m4_define([gnt_version_minor], [1]) -m4_define([gnt_version_revision], [0]) +m4_define([gnt_version_revision], [1]) m4_define([gnt_version_suffix], []) m4_define([gnt_version_full], m4_format([%d.%d.%d%s], diff --git a/lib/cmdlib.py b/lib/cmdlib.py index 4b6b7783309b12985fb9720a88d18770a825895c..2b26f1b6bc5c150767f73f1819eb7f829c18340d 100644 --- a/lib/cmdlib.py +++ b/lib/cmdlib.py @@ -2111,6 +2111,20 @@ class LUSetClusterParams(LogicalUnit): hv_class.CheckParameterSyntax(hv_params) _CheckHVParams(self, node_list, hv_name, hv_params) + if self.op.os_hvp: + # no need to check any newly-enabled hypervisors, since the + # defaults have already been checked in the above code-block + for os_name, os_hvp in self.new_os_hvp.items(): + for hv_name, hv_params in os_hvp.items(): + utils.ForceDictType(hv_params, constants.HVS_PARAMETER_TYPES) + # we need to fill in the new os_hvp on top of the actual hv_p + cluster_defaults = self.new_hvparams.get(hv_name, {}) + new_osp = objects.FillDict(cluster_defaults, hv_params) + hv_class = hypervisor.GetHypervisor(hv_name) + hv_class.CheckParameterSyntax(new_osp) + _CheckHVParams(self, node_list, hv_name, new_osp) + + def Exec(self, feedback_fn): """Change the parameters of the cluster.
