Version 2.5.0 beta1
5 88bc199a Michael Hanselmann
-------------------
6 88bc199a Michael Hanselmann
7 88bc199a Michael Hanselmann
*(unreleased)*
8 88bc199a Michael Hanselmann
9 88bc199a Michael Hanselmann
- The default of the ``/2/instances/[instance_name]/rename`` RAPI
10 88bc199a Michael Hanselmann
  resource's ``ip_check`` parameter changed from ``True`` to ``False``
11 88bc199a Michael Hanselmann
  to match the underlying LUXI interface
12 526a662a Michael Hanselmann
- When creating file-based instances via RAPI, the ``file_driver``
13 526a662a Michael Hanselmann
  parameter no longer defaults to ``loop`` and must be specified
14 72f0ef8e Guido Trotter
- The deprecated "bridge" nic parameter is no longer supported. Use
15 72f0ef8e Guido Trotter
  "link" instead.
16 3fd7f652 Michael Hanselmann
- Support for the undocumented and deprecated RAPI instance creation
17 3fd7f652 Michael Hanselmann
  request format version 0 has been dropped. Use version 1, supported
18 3fd7f652 Michael Hanselmann
  since Ganeti 2.1.3 and :doc:`documented <rapi>`, instead.
19 7578ab0a Michael Hanselmann
- Pyparsing 1.4.6 or above is required, see :doc:`installation
20 7578ab0a Michael Hanselmann
  documentation <install>`
21 56372573 Guido Trotter
- The "cluster-verify" hooks are now executed per group by the
22 56372573 Guido Trotter
  OP_CLUSTER_VERIFY_GROUP opcode. This maintains the same behavior if
23 56372573 Guido Trotter
  you just run "gnt-cluster verify", which generates one op per group.

*(unreleased)*
30 6e1156ff Iustin Pop
31 6e1156ff Iustin Pop
- Added a new parameter to instance stop/start called ``--no-remember``
32 6e1156ff Iustin Pop
  that will make the state change to not be remembered

Version 2.4.2
36 1bbf0c40 Iustin Pop
-------------
37 1bbf0c40 Iustin Pop
38 ccce780c Iustin Pop
*(Released Thu, 12 May 2011)*
39 1bbf0c40 Iustin Pop
40 1bbf0c40 Iustin Pop
Many bug-fixes and a few new small features:
41 1bbf0c40 Iustin Pop
42 1bbf0c40 Iustin Pop
- Fixed a bug related to log opening failures
43 1bbf0c40 Iustin Pop
- Fixed a bug in instance listing with orphan instances
44 1bbf0c40 Iustin Pop
- Fixed a bug which prevented resetting the cluster-level node parameter
45 1bbf0c40 Iustin Pop
  ``oob_program`` to the default
46 1bbf0c40 Iustin Pop
- Many fixes related to the ``cluster-merge`` tool
47 1bbf0c40 Iustin Pop
- Fixed a race condition in the lock monitor, which caused failures
48 1bbf0c40 Iustin Pop
  during (at least) creation of many instances in parallel
49 1bbf0c40 Iustin Pop
- Improved output for gnt-job info
50 1bbf0c40 Iustin Pop
- Removed the quiet flag on some ssh calls which prevented debugging
51 1bbf0c40 Iustin Pop
  failures
52 1bbf0c40 Iustin Pop
- Improved the N+1 failure messages in cluster verify by actually
53 1bbf0c40 Iustin Pop
  showing the memory values (needed and available)
54 1bbf0c40 Iustin Pop
- Increased lock attempt timeouts so that when executing long operations
55 1bbf0c40 Iustin Pop
  (e.g. DRBD replace-disks) other jobs do not enter 'blocking acquire'
56 1bbf0c40 Iustin Pop
  too early and thus prevent the use of the 'fair' mechanism
57 1bbf0c40 Iustin Pop
- Changed instance query data (``gnt-instance info``) to not acquire
58 1bbf0c40 Iustin Pop
  locks unless needed, thus allowing its use on locked instance if only
59 1bbf0c40 Iustin Pop
  static information is asked for
60 1bbf0c40 Iustin Pop
- Improved behaviour with filesystems that do not support rename on an
61 1bbf0c40 Iustin Pop
  opened file
62 1bbf0c40 Iustin Pop
- Fixed the behaviour of ``prealloc_wipe_disks`` cluster parameter which
63 1bbf0c40 Iustin Pop
  kept locks on all nodes during the wipe, which is unneeded
64 1bbf0c40 Iustin Pop
- Fixed ``gnt-watcher`` handling of errors during hooks execution
65 1bbf0c40 Iustin Pop
- Fixed bug in ``prealloc_wipe_disks`` with small disk sizes (less than
66 1bbf0c40 Iustin Pop
  10GiB) which caused the wipe to fail right at the end in some cases
67 1bbf0c40 Iustin Pop
- Fixed master IP activation when doing master failover with no-voting
68 1bbf0c40 Iustin Pop
- Fixed bug in ``gnt-node add --readd`` which allowed the re-adding of
69 1bbf0c40 Iustin Pop
  the master node itself
70 1bbf0c40 Iustin Pop
- Fixed potential data-loss in under disk full conditions, where Ganeti
71 1bbf0c40 Iustin Pop
  wouldn't check correctly the return code and would consider
72 1bbf0c40 Iustin Pop
  partially-written files 'correct'
73 1bbf0c40 Iustin Pop
- Fixed bug related to multiple VGs and DRBD disk replacing
74 1bbf0c40 Iustin Pop
- Added new disk parameter ``metavg`` that allows placement of the meta
75 1bbf0c40 Iustin Pop
  device for DRBD in a different volume group
76 1bbf0c40 Iustin Pop
- Fixed error handling in the node daemon when the system libc doesn't
77 1bbf0c40 Iustin Pop
  have major number 6 (i.e. if ``libc.so.6`` is not the actual libc)
78 1bbf0c40 Iustin Pop
- Fixed lock release during replace-disks, which kept cluster-wide locks
79 1bbf0c40 Iustin Pop
  when doing disk replaces with an iallocator script
80 1bbf0c40 Iustin Pop
- Added check for missing bridges in cluster verify
81 1bbf0c40 Iustin Pop
- Handle EPIPE errors while writing to the terminal better, so that
82 1bbf0c40 Iustin Pop
  piping the output to e.g. ``less`` doesn't cause a backtrace
83 1bbf0c40 Iustin Pop
- Fixed rare case where a ^C during Luxi calls could have been
84 1bbf0c40 Iustin Pop
  interpreted as server errors, instead of simply terminating
85 1bbf0c40 Iustin Pop
- Fixed a race condition in LUGroupAssignNodes (``gnt-group
86 1bbf0c40 Iustin Pop
  assign-nodes``)
87 1bbf0c40 Iustin Pop
- Added a few more parameters to the KVM hypervisor, allowing a second
88 1bbf0c40 Iustin Pop
  CDROM, custom disk type for CDROMs and a floppy image
89 1bbf0c40 Iustin Pop
- Removed redundant message in instance rename when the name is given
90 1bbf0c40 Iustin Pop
  already as a FQDN
91 1bbf0c40 Iustin Pop
- Added option to ``gnt-instance recreate-disks`` to allow creating the
92 1bbf0c40 Iustin Pop
  disks on new nodes, allowing recreation when the original instance
93 1bbf0c40 Iustin Pop
  nodes are completely gone
94 1bbf0c40 Iustin Pop
- Added option when converting disk templates to DRBD to skip waiting
95 1bbf0c40 Iustin Pop
  for the resync, in order to make the instance available sooner
96 1bbf0c40 Iustin Pop
- Added two new variables to the OS scripts environment (containing the
97 1bbf0c40 Iustin Pop
  instance's nodes)
98 1bbf0c40 Iustin Pop
- Made the root_path and optional parameter for the xen-pvm hypervisor,
99 1bbf0c40 Iustin Pop
  to allow use of ``pvgrub`` as bootloader
100 b92a2f3e Iustin Pop
- Changed the instance memory modifications to only check out-of-memory
101 b92a2f3e Iustin Pop
  conditions on memory increases, and turned the secondary node warnings
102 b92a2f3e Iustin Pop
  into errors (they can still be overridden via ``--force``)
103 f01738fc Iustin Pop
- Fixed the handling of a corner case when the Python installation gets
104 f01738fc Iustin Pop
  corrupted (e.g. a bad disk) while ganeti-noded is running and we try
105 f01738fc Iustin Pop
  to execute a command that doesn't exist
106 bb851c63 Iustin Pop
- Fixed a bug in ``gnt-instance move`` (LUInstanceMove) when the primary
107 bb851c63 Iustin Pop
  node of the instance returned failures during instance shutdown; this
108 bb851c63 Iustin Pop
  adds the option ``--ignore-consistency`` to gnt-instance move
109 1bbf0c40 Iustin Pop
110 1bbf0c40 Iustin Pop
And as usual, various improvements to the error messages, documentation
111 1bbf0c40 Iustin Pop
and man pages.
112 1bbf0c40 Iustin Pop
113 c199dbae Iustin Pop
Version 2.4.1
114 c199dbae Iustin Pop
-------------
115 c199dbae Iustin Pop

*(Released Wed, 09 Mar 2011)*
117 c199dbae Iustin Pop
118 c199dbae Iustin Pop
Emergency bug-fix release. ``tools/cfgupgrade`` was broken and overwrote
119 c199dbae Iustin Pop
the RAPI users file if run twice (even with ``-dry-run``).
120 c199dbae Iustin Pop
121 c199dbae Iustin Pop
The release fixes that bug (nothing else changed).
122 c199dbae Iustin Pop
123 c199dbae Iustin Pop
124 20203756 Iustin Pop
Version 2.4.0
125 20203756 Iustin Pop
-------------
126 20203756 Iustin Pop
127 20203756 Iustin Pop
*(Released Mon, 07 Mar 2011)*
128 20203756 Iustin Pop
129 20203756 Iustin Pop
Final 2.4.0 release. Just a few small fixes:
130 20203756 Iustin Pop
131 20203756 Iustin Pop

135 20203756 Iustin Pop
136 20203756 Iustin Pop
137 94b697b0 Iustin Pop
Version 2.4.0 rc3
138 94b697b0 Iustin Pop
-----------------
139 94b697b0 Iustin Pop
140 94b697b0 Iustin Pop
*(Released Mon, 28 Feb 2011)*
141 94b697b0 Iustin Pop
142 94b697b0 Iustin Pop
A critical fix for the ``prealloc_wipe_disks`` feature: it is possible
143 94b697b0 Iustin Pop
that this feature wiped the disks of the wrong instance, leading to loss
144 94b697b0 Iustin Pop
of data.
145 94b697b0 Iustin Pop
146 94b697b0 Iustin Pop
Other changes:
147 94b697b0 Iustin Pop
148 df3df936 Michael Hanselmann
- Fixed title of query field containing instance name
149 df3df936 Michael Hanselmann
- Expanded the glossary in the documentation

*(Released Mon, 21 Feb 2011)*
157 e41a1c0c Iustin Pop
158 e41a1c0c Iustin Pop
A number of bug fixes plus just a couple functionality changes.
159 e41a1c0c Iustin Pop
160 e41a1c0c Iustin Pop
On the user-visible side, the ``gnt-* list`` command output has changed
161 df3df936 Michael Hanselmann
with respect to "special" field states. The current rc1 style of display
162 df3df936 Michael Hanselmann
can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in
163 df3df936 Michael Hanselmann
the default output mode special fields states are displayed as follows:
164 e41a1c0c Iustin Pop
165 df3df936 Michael Hanselmann
- Offline resource: ``*``
166 df3df936 Michael Hanselmann
- Unavailable/not applicable: ``-``
167 df3df936 Michael Hanselmann
- Data missing (RPC failure): ``?``
168 df3df936 Michael Hanselmann
- Unknown field: ``??``
169 e41a1c0c Iustin Pop
170 e41a1c0c Iustin Pop
Another user-visible change is the addition of ``--force-join`` to
171 e41a1c0c Iustin Pop
``gnt-node add``.
172 e41a1c0c Iustin Pop
173 e41a1c0c Iustin Pop
As for bug fixes:
174 e41a1c0c Iustin Pop
175 e41a1c0c Iustin Pop
- ``tools/cluster-merge`` has seen many fixes and is now enabled again
176 df3df936 Michael Hanselmann
- Fixed regression in RAPI/instance reinstall where all parameters were
177 e41a1c0c Iustin Pop
  required (instead of optional)
178 df3df936 Michael Hanselmann
- Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2
179 df3df936 Michael Hanselmann
- Fixed iallocator usage (offline nodes were not considered offline)
180 df3df936 Michael Hanselmann
- Fixed ``gnt-node list`` with respect to non-vm_capable nodes
181 df3df936 Michael Hanselmann
- Fixed hypervisor and OS parameter validation with respect to
182 e41a1c0c Iustin Pop
  non-vm_capable nodes
183 df3df936 Michael Hanselmann
- Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly
184 e41a1c0c Iustin Pop
  cosmetic)
185 df3df936 Michael Hanselmann
- Fixed ``tools/listrunner`` with respect to agent-based usage
186 e41a1c0c Iustin Pop
187 e41a1c0c Iustin Pop
188 ec31a18f Iustin Pop
Version 2.4.0 rc1
189 ec31a18f Iustin Pop
-----------------
190 ec31a18f Iustin Pop
191 ec31a18f Iustin Pop
*(Released Fri,  4 Feb 2011)*
192 ec31a18f Iustin Pop
193 ec31a18f Iustin Pop
Many changes and fixes since the beta1 release. While there were some
194 ec31a18f Iustin Pop
internal changes, the code has been mostly stabilised for the RC
195 ec31a18f Iustin Pop
release.
196 ec31a18f Iustin Pop
197 ec31a18f Iustin Pop
Note: the dumb allocator was removed in this release, as it was not kept
198 ec31a18f Iustin Pop
up-to-date with the IAllocator protocol changes. It is recommended to
199 ec31a18f Iustin Pop
use the ``hail`` command from the ganeti-htools package.
200 ec31a18f Iustin Pop
201 ec31a18f Iustin Pop
Note: the 2.4 and up versions of Ganeti are not compatible with the
202 ec31a18f Iustin Pop
0.2.x branch of ganeti-htools. You need to upgrade to
203 ec31a18f Iustin Pop
ganeti-htools-0.3.0 (or later).
204 ec31a18f Iustin Pop
205 ec31a18f Iustin Pop
Regressions fixed from 2.3
206 ec31a18f Iustin Pop
~~~~~~~~~~~~~~~~~~~~~~~~~~
207 ec31a18f Iustin Pop
208 ec31a18f Iustin Pop
- Fixed the ``gnt-cluster verify-disks`` command
209 ec31a18f Iustin Pop
- Made ``gnt-cluster verify-disks`` work in parallel (as opposed to
210 ec31a18f Iustin Pop
  serially on nodes)
211 ec31a18f Iustin Pop
- Fixed disk adoption breakage
212 ec31a18f Iustin Pop
- Fixed wrong headers in instance listing for field aliases
213 ec31a18f Iustin Pop
214 ec31a18f Iustin Pop
Other bugs fixed
215 ec31a18f Iustin Pop
~~~~~~~~~~~~~~~~
216 ec31a18f Iustin Pop
217 ec31a18f Iustin Pop
- Fixed corner case in KVM handling of NICs
218 ec31a18f Iustin Pop
- Fixed many cases of wrong handling of non-vm_capable nodes
219 ec31a18f Iustin Pop
- Fixed a bug where a missing instance symlink was not possible to
220 ec31a18f Iustin Pop
  recreate with any ``gnt-*`` command (now ``gnt-instance
221 ec31a18f Iustin Pop
  activate-disks`` does it)
222 ec31a18f Iustin Pop
- Fixed the volume group name as reported by ``gnt-cluster
223 ec31a18f Iustin Pop
  verify-disks``
224 ec31a18f Iustin Pop
- Increased timeouts for the import-export code, hopefully leading to
225 ec31a18f Iustin Pop
  fewer aborts due network or instance timeouts
226 ec31a18f Iustin Pop
- Fixed bug in ``gnt-node list-storage``
227 ec31a18f Iustin Pop
- Fixed bug where not all daemons were started on cluster
228 ec31a18f Iustin Pop
  initialisation, but only at the first watcher run
229 ec31a18f Iustin Pop
- Fixed many bugs in the OOB implementation
230 ec31a18f Iustin Pop
- Fixed watcher behaviour in presence of instances with offline
231 ec31a18f Iustin Pop
  secondaries
232 ec31a18f Iustin Pop
- Fixed instance list output for instances running on the wrong node
233 ec31a18f Iustin Pop
- a few fixes to the cluster-merge tool, but it still cannot merge
234 ec31a18f Iustin Pop
  multi-node groups (currently it is not recommended to use this tool)
235 ec31a18f Iustin Pop
236 ec31a18f Iustin Pop
237 ec31a18f Iustin Pop
Improvements
238 ec31a18f Iustin Pop
~~~~~~~~~~~~
239 ec31a18f Iustin Pop
240 ec31a18f Iustin Pop
- Improved network configuration for the KVM hypervisor
241 ec31a18f Iustin Pop
- Added e1000 as a supported NIC for Xen-HVM
242 ec31a18f Iustin Pop
- Improved the lvmstrap tool to also be able to use partitions, as
243 ec31a18f Iustin Pop
  opposed to full disks
244 ec31a18f Iustin Pop
- Improved speed of disk wiping (the cluster parameter
245 ec31a18f Iustin Pop
  ``prealloc_wipe_disks``, so that it has a low impact on the total time
246 ec31a18f Iustin Pop
  of instance creations
247 ec31a18f Iustin Pop
- Added documentation for the OS parameters
248 ec31a18f Iustin Pop
- Changed ``gnt-instance deactivate-disks`` so that it can work if the
249 ec31a18f Iustin Pop
  hypervisor is not responding
250 ec31a18f Iustin Pop
- Added display of blacklisted and hidden OS information in
251 ec31a18f Iustin Pop
  ``gnt-cluster info``
252 ec31a18f Iustin Pop
- Extended ``gnt-cluster verify`` to also validate hypervisor, backend,
253 ec31a18f Iustin Pop
  NIC and node parameters, which might create problems with currently
254 ec31a18f Iustin Pop
  invalid (but undetected) configuration files, but prevents validation
255 ec31a18f Iustin Pop
  failures when unrelated parameters are modified
256 ec31a18f Iustin Pop
- Changed cluster initialisation to wait for the master daemon to become
257 ec31a18f Iustin Pop
  available
258 ec31a18f Iustin Pop
- Expanded the RAPI interface:
259 ec31a18f Iustin Pop
260 ec31a18f Iustin Pop
  - Added config redistribution resource
261 ec31a18f Iustin Pop
  - Added activation/deactivation of instance disks
262 ec31a18f Iustin Pop
  - Added export of console information
263 ec31a18f Iustin Pop
264 ec31a18f Iustin Pop
- Implemented log file reopening on SIGHUP, which allows using
265 ec31a18f Iustin Pop
  logrotate(8) for the Ganeti log files
266 ec31a18f Iustin Pop
- Added a basic OOB helper script as an example
267 ec31a18f Iustin Pop
268 ec31a18f Iustin Pop

302 fdd9ac5b Michael Hanselmann
- Moved ``rapi_users`` file into separate directory, now named
303 df3df936 Michael Hanselmann
  ``.../ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a

314 d7a08491 Michael Hanselmann
- Changed query operations to return more detailed information, e.g.
315 d7a08491 Michael Hanselmann
  whether an information is unavailable due to an offline node. To use
316 d7a08491 Michael Hanselmann
  this new functionality, the LUXI call ``Query`` must be used. Field
317 d7a08491 Michael Hanselmann
  information is now stored by the master daemon and can be retrieved
318 3daa24ea Michael Hanselmann
  using ``QueryFields``. Instances, nodes and groups can also be queried
319 3daa24ea Michael Hanselmann
  using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet
320 3daa24ea Michael Hanselmann
  exposed via RAPI). The following commands make use of this
321 3daa24ea Michael Hanselmann
  infrastructure change:
322 3daa24ea Michael Hanselmann
323 3daa24ea Michael Hanselmann
  - ``gnt-group list``

547 529a8d17 Iustin Pop
Version 2.2.0 rc0
548 529a8d17 Iustin Pop
-----------------
549 529a8d17 Iustin Pop
550 41c44dcf Iustin Pop
*(Released Fri, 30 Jul 2010)*
551 529a8d17 Iustin Pop
552 529a8d17 Iustin Pop
Important change: the internal RPC mechanism between Ganeti nodes has
553 529a8d17 Iustin Pop
changed from using a home-grown http library (based on the Python base
554 529a8d17 Iustin Pop
libraries) to use the PycURL library. This requires that PycURL is
555 529a8d17 Iustin Pop
installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
556 529a8d17 Iustin Pop
against GnuTLS by default. cURL's support for GnuTLS had known issues
557 529a8d17 Iustin Pop
before cURL 7.21.0 and we recommend using the latest cURL release or
558 529a8d17 Iustin Pop
linking against OpenSSL. Most other distributions already link PycURL
559 529a8d17 Iustin Pop
and cURL against OpenSSL. The command::
560 529a8d17 Iustin Pop
561 529a8d17 Iustin Pop
  python -c 'import pycurl; print pycurl.version'
562 529a8d17 Iustin Pop
563 529a8d17 Iustin Pop
can be used to determine the libraries PycURL and cURL are linked
564 529a8d17 Iustin Pop
against.
565 529a8d17 Iustin Pop
566 529a8d17 Iustin Pop
Other significant changes:
567 529a8d17 Iustin Pop
568 529a8d17 Iustin Pop
- Rewrote much of the internals of the job queue, in order to achieve
569 529a8d17 Iustin Pop
  better parallelism; this decouples job query operations from the job
570 529a8d17 Iustin Pop
  processing, and it should allow much nicer behaviour of the master
571 529a8d17 Iustin Pop
  daemon under load, and it also has uncovered some long-standing bugs
572 529a8d17 Iustin Pop
  related to the job serialisation (now fixed)
573 529a8d17 Iustin Pop
- Added a default iallocator setting to the cluster parameters,
574 529a8d17 Iustin Pop
  eliminating the need to always pass nodes or an iallocator for
575 529a8d17 Iustin Pop
  operations that require selection of new node(s)
576 529a8d17 Iustin Pop
- Added experimental support for the LXC virtualization method
577 529a8d17 Iustin Pop
- Added support for OS parameters, which allows the installation of
578 529a8d17 Iustin Pop
  instances to pass parameter to OS scripts in order to customise the
579 529a8d17 Iustin Pop
  instance
580 529a8d17 Iustin Pop
- Added a hypervisor parameter controlling the migration type (live or
581 529a8d17 Iustin Pop
  non-live), since hypervisors have various levels of reliability; this
582 529a8d17 Iustin Pop
  has renamed the 'live' parameter to 'mode'
583 529a8d17 Iustin Pop
- Added a cluster parameter ``reserved_lvs`` that denotes reserved
584 529a8d17 Iustin Pop
  logical volumes, meaning that cluster verify will ignore them and not
585 529a8d17 Iustin Pop
  flag their presence as errors
586 529a8d17 Iustin Pop
- The watcher will now reset the error count for failed instances after
587 529a8d17 Iustin Pop
  8 hours, thus allowing self-healing if the problem that caused the
588 529a8d17 Iustin Pop
  instances to be down/fail to start has cleared in the meantime
589 529a8d17 Iustin Pop
- Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
590 529a8d17 Iustin Pop
  check for, and warn, if the drbd module parameter ``usermode_helper``
591 529a8d17 Iustin Pop
  is not consistent with the cluster-wide setting; this is needed to
592 529a8d17 Iustin Pop
  make diagnose easier of failed drbd creations
593 529a8d17 Iustin Pop
- Started adding base IPv6 support, but this is not yet
594 529a8d17 Iustin Pop
  enabled/available for use
595 529a8d17 Iustin Pop
- Rename operations (cluster, instance) will now return the new name,
596 529a8d17 Iustin Pop
  which is especially useful if a short name was passed in
597 529a8d17 Iustin Pop
- Added support for instance migration in RAPI
598 529a8d17 Iustin Pop
- Added a tool to pre-configure nodes for the SSH setup, before joining
599 529a8d17 Iustin Pop
  them to the cluster; this will allow in the future a simplified model
600 529a8d17 Iustin Pop
  for node joining (but not yet fully enabled in 2.2); this needs the
601 529a8d17 Iustin Pop
  paramiko python library
602 529a8d17 Iustin Pop
- Fixed handling of name-resolving errors
603 529a8d17 Iustin Pop
- Fixed consistency of job results on the error path

627 ab221ddf Michael Hanselmann
628 e0897adf Michael Hanselmann
- Added tool (``move-instance``) and infrastructure to move instances
629 e0897adf Michael Hanselmann
  between separate clusters (see :doc:`separate documentation
630 e0897adf Michael Hanselmann
  <move-instance>` and :doc:`design document <design-2.2>`)
631 e0897adf Michael Hanselmann
- Added per-request RPC timeout
632 ab221ddf Michael Hanselmann
- RAPI now requires a Content-Type header for requests with a body (e.g.
633 ab221ddf Michael Hanselmann
  ``PUT`` or ``POST``) which must be set to ``application/json`` (see
634 a4978169 Michael Hanselmann
  :rfc:`2616` (HTTP/1.1), section 7.2.1)
635 e0897adf Michael Hanselmann

636 e0897adf Michael Hanselmann
  reachable
637 e0897adf Michael Hanselmann
- Implemented initial support for running Ganeti daemons as separate
638 e0897adf Michael Hanselmann
  users, see configure-time flags ``--with-user-prefix`` and
639 e0897adf Michael Hanselmann
  ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
640 e0897adf Michael Hanselmann
  time)
641 e0897adf Michael Hanselmann
- Instances can be removed after export (``gnt-backup export
642 e0897adf Michael Hanselmann
  --remove-instance``)
643 e0897adf Michael Hanselmann
- Self-signed certificates generated by Ganeti now use a 2048 bit RSA
644 e0897adf Michael Hanselmann
  key (instead of 1024 bit)
645 e0897adf Michael Hanselmann
- Added new cluster configuration file for cluster domain secret
646 e0897adf Michael Hanselmann
- Import/export now use SSL instead of SSH
647 e0897adf Michael Hanselmann
- Added support for showing estimated time when exporting an instance,
648 e0897adf Michael Hanselmann
  see the ``ganeti-os-interface(7)`` manpage and look for

690 ae828011 Guido Trotter
    (on some hypervisors consequent reboots are not supported)
691 ae828011 Guido Trotter
  - Fix infrequent race condition in master failover. Sometimes the old
692 ae828011 Guido Trotter
    master ip address would be still detected as up for a short time
693 ae828011 Guido Trotter
    after it was removed, causing failover to fail.
694 ae828011 Guido Trotter
  - Decrease mlockall warnings when the ctypes module is missing. On
695 ae828011 Guido Trotter
    Python 2.4 we support running even if no ctypes module is installed,
696 ae828011 Guido Trotter

749 14d91053 Guido Trotter
A medium sized development cycle. Some new features, and some

fixes/small improvements/cleanups.
751 14d91053 Guido Trotter
752 14d91053 Guido Trotter
Significant features
753 14d91053 Guido Trotter
~~~~~~~~~~~~~~~~~~~~
754 14d91053 Guido Trotter
755 14d91053 Guido Trotter
The node deamon now tries to mlock itself into memory, unless the
756 14d91053 Guido Trotter
``--no-mlock`` flag is passed. It also doesn't fail if it can't write
757 14d91053 Guido Trotter
its logs, and falls back to console logging. This allows emergency
758 14d91053 Guido Trotter
features such as ``gnt-node powercycle`` to work even in the event of a
759 14d91053 Guido Trotter
broken node disk (tested offlining the disk hosting the node's
760 722702e3 Guido Trotter
filesystem and dropping its memory caches; don't try this at home)
761 14d91053 Guido Trotter
762 14d91053 Guido Trotter
KVM: add vhost-net acceleration support. It can be tested with a new
763 14d91053 Guido Trotter
enough version of the kernel and of qemu-kvm.
764 14d91053 Guido Trotter
765 14d91053 Guido Trotter
KVM: Add instance chrooting feature. If you use privilege dropping for
766 14d91053 Guido Trotter
your VMs you can also now force them to chroot to an empty directory,
767 14d91053 Guido Trotter
before starting the emulated guest.
768 14d91053 Guido Trotter
769 14d91053 Guido Trotter
KVM: Add maximum migration bandwith and maximum downtime tweaking
770 14d91053 Guido Trotter
support (requires a new-enough version of qemu-kvm).
771 14d91053 Guido Trotter
772 14d91053 Guido Trotter
Cluster verify will now warn if the master node doesn't have the master
773 14d91053 Guido Trotter
ip configured on it.
774 14d91053 Guido Trotter
775 14d91053 Guido Trotter
Add a new (incompatible) instance creation request format to RAPI which
776 14d91053 Guido Trotter
supports all parameters (previously only a subset was supported, and it
777 14d91053 Guido Trotter
wasn't possible to extend the old format to accomodate all the new
778 14d91053 Guido Trotter
features. The old format is still supported, and a client can check for
779 14d91053 Guido Trotter
this feature, before using it, by checking for its presence in the
780 14d91053 Guido Trotter
``features`` RAPI resource.
781 14d91053 Guido Trotter
782 14d91053 Guido Trotter
Now with ancient latin support. Try it passing the ``--roman`` option to
783 722702e3 Guido Trotter
``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
784 722702e3 Guido Trotter
(requires the python-roman module to be installed, in order to work).

Other changes
787 14d91053 Guido Trotter
~~~~~~~~~~~~~
788 14d91053 Guido Trotter
789 14d91053 Guido Trotter
As usual many internal code refactorings, documentation updates, and
790 14d91053 Guido Trotter
such. Among others:
791 14d91053 Guido Trotter
792 14d91053 Guido Trotter
  - Lots of improvements and cleanups to the experimental Remote API
793 14d91053 Guido Trotter
    (RAPI) client library.
794 14d91053 Guido Trotter
  - A new unit test suite for the core daemon libraries.
795 14d91053 Guido Trotter
  - A fix to creating missing directories makes sure the umask is not
796 14d91053 Guido Trotter
    applied anymore. This enforces the same directory permissions
797 14d91053 Guido Trotter
    everywhere.
798 14d91053 Guido Trotter
  - Better handling terminating daemons with ctrl+c (used when running
799 14d91053 Guido Trotter
    them in debugging mode).
800 14d91053 Guido Trotter
  - Fix a race condition in live migrating a KVM instance, when stat()
801 14d91053 Guido Trotter
    on the old proc status file returned EINVAL, which is an unexpected
802 14d91053 Guido Trotter
    value.
803 1de45c78 Guido Trotter
  - Fixed manpage checking with newer man and utf-8 charachters. But now
804 1de45c78 Guido Trotter
    you need the en_US.UTF-8 locale enabled to build Ganeti from git.

819 ba538816 Iustin Pop
820 ba538816 Iustin Pop
Another release with a long development cycle, during which many
821 ba538816 Iustin Pop
different features were added.
822 ba538816 Iustin Pop
823 ba538816 Iustin Pop
Significant features
824 ba538816 Iustin Pop
~~~~~~~~~~~~~~~~~~~~
825 ba538816 Iustin Pop
826 ba538816 Iustin Pop
The KVM hypervisor now can run the individual instances as non-root, to
827 ba538816 Iustin Pop
reduce the impact of a VM being hijacked due to bugs in the
828 ba538816 Iustin Pop
hypervisor. It is possible to run all instances as a single (non-root)
829 ba538816 Iustin Pop
user, to manually specify a user for each instance, or to dynamically
830 ba538816 Iustin Pop
allocate a user out of a cluster-wide pool to each instance, with the
831 ba538816 Iustin Pop
guarantee that no two instances will run under the same user ID on any
832 ba538816 Iustin Pop
given node.
833 ba538816 Iustin Pop
834 ba538816 Iustin Pop
An experimental RAPI client library, that can be used standalone
835 ba538816 Iustin Pop
(without the other Ganeti libraries), is provided in the source tree as
836 ba538816 Iustin Pop
``lib/rapi/client.py``. Note this client might change its interface in
837 ba538816 Iustin Pop
the future, as we iterate on its capabilities.
838 ba538816 Iustin Pop
839 ba538816 Iustin Pop
A new command, ``gnt-cluster renew-crypto`` has been added to easily
840 ba538816 Iustin Pop
replace the cluster's certificates and crypto keys. This might help in
841 ba538816 Iustin Pop
case they have been compromised, or have simply expired.
842 ba538816 Iustin Pop
843 ba538816 Iustin Pop
A new disk option for instance creation has been added that allows one
844 ba538816 Iustin Pop
to "adopt" currently existing logical volumes, with data
845 ba538816 Iustin Pop
preservation. This should allow easier migration to Ganeti from
846 ba538816 Iustin Pop
unmanaged (or managed via other software) instances.
847 ba538816 Iustin Pop
848 ba538816 Iustin Pop
Another disk improvement is the possibility to convert between redundant
849 ba538816 Iustin Pop
(DRBD) and plain (LVM) disk configuration for an instance. This should
850 ba538816 Iustin Pop
allow better scalability (starting with one node and growing the
851 ba538816 Iustin Pop
cluster, or shrinking a two-node cluster to one node).
852 ba538816 Iustin Pop
853 ba538816 Iustin Pop
A new feature that could help with automated node failovers has been
854 ba538816 Iustin Pop
implemented: if a node sees itself as offline (by querying the master
855 ba538816 Iustin Pop
candidates), it will try to shutdown (hard) all instances and any active
856 ba538816 Iustin Pop
DRBD devices. This reduces the risk of duplicate instances if an
857 ba538816 Iustin Pop
external script automatically failovers the instances on such nodes. To
858 ba538816 Iustin Pop
enable this, the cluster parameter ``maintain_node_health`` should be
859 ba538816 Iustin Pop
enabled; in the future this option (per the name) will enable other
860 ba538816 Iustin Pop
automatic maintenance features.
861 ba538816 Iustin Pop
862 ba538816 Iustin Pop
Instance export/import now will reuse the original instance
863 ba538816 Iustin Pop
specifications for all parameters; that means exporting an instance,
864 ba538816 Iustin Pop
deleting it and the importing it back should give an almost identical
865 ba538816 Iustin Pop
instance. Note that the default import behaviour has changed from
866 ba538816 Iustin Pop
before, where it created only one NIC; now it recreates the original
867 ba538816 Iustin Pop
number of NICs.
868 ba538816 Iustin Pop
869 ba538816 Iustin Pop
Cluster verify has added a few new checks: SSL certificates validity,
870 ba538816 Iustin Pop
/etc/hosts consistency across the cluster, etc.
871 ba538816 Iustin Pop
872 ba538816 Iustin Pop
Other changes
873 ba538816 Iustin Pop
~~~~~~~~~~~~~
874 ba538816 Iustin Pop
875 ba538816 Iustin Pop
As usual, many internal changes were done, documentation fixes,
876 ba538816 Iustin Pop
etc. Among others:
877 ba538816 Iustin Pop
878 ba538816 Iustin Pop
- Fixed cluster initialization with disabled cluster storage (regression
879 ba538816 Iustin Pop
  introduced in 2.1.1)
880 ba538816 Iustin Pop
- File-based storage supports growing the disks
881 ba538816 Iustin Pop
- Fixed behaviour of node role changes
882 ba538816 Iustin Pop
- Fixed cluster verify for some corner cases, plus a general rewrite of
883 ba538816 Iustin Pop
  cluster verify to allow future extension with more checks
884 ba538816 Iustin Pop
- Fixed log spamming by watcher and node daemon (regression introduced
885 ba538816 Iustin Pop
  in 2.1.1)
886 ba538816 Iustin Pop
- Fixed possible validation issues when changing the list of enabled
887 ba538816 Iustin Pop
  hypervisors
888 ba538816 Iustin Pop
- Fixed cleanup of /etc/hosts during node removal
889 ba538816 Iustin Pop
- Fixed RAPI response for invalid methods
890 ba538816 Iustin Pop
- Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
891 ba538816 Iustin Pop
- Multiple small improvements to the KVM hypervisor (VNC usage, booting
892 ba538816 Iustin Pop
  from ide disks, etc.)
893 ba538816 Iustin Pop
- Allow OS changes without re-installation (to record a changed OS
894 ba538816 Iustin Pop
  outside of Ganeti, or to allow OS renames)
895 ba538816 Iustin Pop
- Allow instance creation without OS installation (useful for example if
896 ba538816 Iustin Pop
  the OS will be installed manually, or restored from a backup not in
897 ba538816 Iustin Pop
  Ganeti format)
898 ba538816 Iustin Pop
- Implemented option to make cluster ``copyfile`` use the replication
899 ba538816 Iustin Pop
  network
900 ba538816 Iustin Pop
- Added list of enabled hypervisors to ssconf (possibly useful for
901 ba538816 Iustin Pop
  external scripts)
902 ba538816 Iustin Pop
- Added a new tool (``tools/cfgupgrade12``) that allows upgrading from

Version 2.1.1
913 c655522d Iustin Pop
-------------

*(Released Fri, 12 Mar 2010)*
916 bdc93557 Iustin Pop
917 c655522d Iustin Pop
During the 2.1.0 long release candidate cycle, a lot of improvements and
918 c655522d Iustin Pop
changes have accumulated with were released later as 2.1.1.
919 c655522d Iustin Pop
920 c655522d Iustin Pop
Major changes
921 c655522d Iustin Pop
~~~~~~~~~~~~~
922 c655522d Iustin Pop
923 c655522d Iustin Pop
The node evacuate command (``gnt-node evacuate``) was significantly
924 c655522d Iustin Pop
rewritten, and as such the IAllocator protocol was changed - a new
925 c655522d Iustin Pop
request type has been added. This unfortunate change during a stable
926 c655522d Iustin Pop
series is designed to improve performance of node evacuations; on
927 c655522d Iustin Pop
clusters with more than about five nodes and which are well-balanced,
928 c655522d Iustin Pop
evacuation should proceed in parallel for all instances of the node
929 c655522d Iustin Pop
being evacuated. As such, any existing IAllocator scripts need to be
930 c655522d Iustin Pop
updated, otherwise the above command will fail due to the unknown
931 c655522d Iustin Pop
request. The provided "dumb" allocator has not been updated; but the
932 c655522d Iustin Pop
ganeti-htools package supports the new protocol since version 0.2.4.
933 c655522d Iustin Pop
934 c655522d Iustin Pop
Another important change is increased validation of node and instance
935 c655522d Iustin Pop
names. This might create problems in special cases, if invalid host
936 c655522d Iustin Pop
names are being used.
937 c655522d Iustin Pop
938 c655522d Iustin Pop
Also, a new layer of hypervisor parameters has been added, that sits at
939 c655522d Iustin Pop
OS level between the cluster defaults and the instance ones. This allows
940 c655522d Iustin Pop
customisation of virtualization parameters depending on the installed
941 c655522d Iustin Pop
OS. For example instances with OS 'X' may have a different KVM kernel
942 c655522d Iustin Pop
(or any other parameter) than the cluster defaults. This is intended to
943 c655522d Iustin Pop
help managing a multiple OSes on the same cluster, without manual
944 c655522d Iustin Pop
modification of each instance's parameters.
945 c655522d Iustin Pop
946 c655522d Iustin Pop
A tool for merging clusters, ``cluster-merge``, has been added in the
947 c655522d Iustin Pop
tools sub-directory.
948 c655522d Iustin Pop
949 c655522d Iustin Pop
Bug fixes
950 c655522d Iustin Pop
~~~~~~~~~
951 c655522d Iustin Pop
952 c655522d Iustin Pop
- Improved the int/float conversions that should make the code more
953 c655522d Iustin Pop
  robust in face of errors from the node daemons
954 c655522d Iustin Pop
- Fixed the remove node code in case of internal configuration errors
955 c655522d Iustin Pop
- Fixed the node daemon behaviour in face of inconsistent queue
956 c655522d Iustin Pop
  directory (e.g. read-only file-system where we can't open the files
957 c655522d Iustin Pop
  read-write, etc.)
958 c655522d Iustin Pop
- Fixed the behaviour of gnt-node modify for master candidate demotion;
959 df3df936 Michael Hanselmann
  now it either aborts cleanly or, if given the new "auto_promote"
960 c655522d Iustin Pop
  parameter, will automatically promote other nodes as needed
961 c655522d Iustin Pop
- Fixed compatibility with (unreleased yet) Python 2.6.5 that would
962 c655522d Iustin Pop
  completely prevent Ganeti from working
963 c655522d Iustin Pop
- Fixed bug for instance export when not all disks were successfully
964 c655522d Iustin Pop
  exported
965 c655522d Iustin Pop
- Fixed behaviour of node add when the new node is slow in starting up
966 c655522d Iustin Pop
  the node daemon
967 c655522d Iustin Pop
- Fixed handling of signals in the LUXI client, which should improve
968 c655522d Iustin Pop
  behaviour of command-line scripts
969 c655522d Iustin Pop
- Added checks for invalid node/instance names in the configuration (now
970 c655522d Iustin Pop
  flagged during cluster verify)
971 c655522d Iustin Pop
- Fixed watcher behaviour for disk activation errors
972 c655522d Iustin Pop
- Fixed two potentially endless loops in http library, which led to the
973 c655522d Iustin Pop
  RAPI daemon hanging and consuming 100% CPU in some cases
974 c655522d Iustin Pop
- Fixed bug in RAPI daemon related to hashed passwords
975 c655522d Iustin Pop
- Fixed bug for unintended qemu-level bridging of multi-NIC KVM
976 c655522d Iustin Pop
  instances
977 c655522d Iustin Pop
- Enhanced compatibility with non-Debian OSes, but not using absolute
978 c655522d Iustin Pop
  path in some commands and allowing customisation of the ssh
979 c655522d Iustin Pop
  configuration directory
980 c655522d Iustin Pop
- Fixed possible future issue with new Python versions by abiding to the
981 c655522d Iustin Pop
  proper use of ``__slots__`` attribute on classes
982 c655522d Iustin Pop
- Added checks that should prevent directory traversal attacks
983 c655522d Iustin Pop
- Many documentation fixes based on feedback from users
984 c655522d Iustin Pop
985 c655522d Iustin Pop
New features
986 c655522d Iustin Pop
~~~~~~~~~~~~
987 c655522d Iustin Pop
988 df3df936 Michael Hanselmann
- Added an "early_release" more for instance replace disks and node
989 c655522d Iustin Pop
  evacuate, where we release locks earlier and thus allow higher
990 c655522d Iustin Pop
  parallelism within the cluster
991 c655522d Iustin Pop
- Added watcher hooks, intended to allow the watcher to restart other
992 c655522d Iustin Pop
  daemons (e.g. from the ganeti-nbma project), but they can be used of
993 c655522d Iustin Pop
  course for any other purpose
994 c655522d Iustin Pop
- Added a compile-time disable for DRBD barriers, to increase
995 c655522d Iustin Pop
  performance if the administrator trusts the power supply or the
996 c655522d Iustin Pop
  storage system to not lose writes
997 c655522d Iustin Pop
- Added the option of using syslog for logging instead of, or in
998 c655522d Iustin Pop
  addition to, Ganeti's own log files
999 c655522d Iustin Pop
- Removed boot restriction for paravirtual NICs for KVM, recent versions
1000 c655522d Iustin Pop
  can indeed boot from a paravirtual NIC
1001 c655522d Iustin Pop
- Added a generic debug level for many operations; while this is not
1002 c655522d Iustin Pop
  used widely yet, it allows one to pass the debug value all the way to
1003 c655522d Iustin Pop
  the OS scripts
1004 c655522d Iustin Pop
- Enhanced the hooks environment for instance moves (failovers,
1005 c655522d Iustin Pop
  migrations) where the primary/secondary nodes changed during the
1006 c655522d Iustin Pop
  operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
1007 c655522d Iustin Pop
- Enhanced data validations for many user-supplied values; one important
1008 c655522d Iustin Pop
  item is the restrictions imposed on instance and node names, which
1009 c655522d Iustin Pop
  might reject some (invalid) host names
1010 c655522d Iustin Pop
- Add a configure-time option to disable file-based storage, if it's not
1011 c655522d Iustin Pop
  needed; this allows greater security separation between the master
1012 c655522d Iustin Pop
  node and the other nodes from the point of view of the inter-node RPC
1013 c655522d Iustin Pop
  protocol
1014 c655522d Iustin Pop
- Added user notification in interactive tools if job is waiting in the
1015 c655522d Iustin Pop
  job queue or trying to acquire locks
1016 c655522d Iustin Pop
- Added log messages when a job is waiting for locks
1017 c655522d Iustin Pop
- Added filtering by node tags in instance operations which admit
1018 c655522d Iustin Pop
  multiple instances (start, stop, reboot, reinstall)
1019 c655522d Iustin Pop
- Added a new tool for cluster mergers, ``cluster-merge``
1020 c655522d Iustin Pop
- Parameters from command line which are of the form ``a=b,c=d`` can now
1021 c655522d Iustin Pop
  use backslash escapes to pass in values which contain commas,
1022 c655522d Iustin Pop
  e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
1023 c655522d Iustin Pop
  ``b,c``
1024 c655522d Iustin Pop
- For KVM, the instance name is the first parameter passed to KVM, so
1025 c655522d Iustin Pop
  that it's more visible in the process list
1026 c655522d Iustin Pop
1027 c655522d Iustin Pop

1041 920a91bf Michael Hanselmann
  locks waiting for other long-running jobs
1042 920a91bf Michael Hanselmann
1043 bfe61b0b Iustin Pop

  /etc/hosts
1186 c8872a0b Iustin Pop
- Added more node information to RAPI responses
1187 aa287e8c Michael Hanselmann

1188 c8872a0b Iustin Pop
  job
1189 c8872a0b Iustin Pop

*(Released Fri, 7 Aug 2009)*
1200 bdc93557 Iustin Pop
1201 61b5e342 Michael Hanselmann
- Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
1202 61b5e342 Michael Hanselmann
  to allow using the pre-2.0.2 behaviour in activation, if any existing
1203 61b5e342 Michael Hanselmann
  instances have mismatched disk sizes in the configuration
1204 7faf5110 Michael Hanselmann
- Added ``gnt-cluster repair-disk-sizes`` command to check and update
1205 7faf5110 Michael Hanselmann
  any configuration mismatches for disk sizes
1206 61b5e342 Michael Hanselmann
- Added ``gnt-master cluste-failover --no-voting`` to allow master
1207 61b5e342 Michael Hanselmann
  failover to work on two-node clusters
1208 aa287e8c Michael Hanselmann
- Fixed the ``--net`` option of ``gnt-backup import``, which was
1209 aa287e8c Michael Hanselmann
  unusable
1210 61b5e342 Michael Hanselmann
- Fixed detection of OS script errors in ``gnt-backup export``
1211 61b5e342 Michael Hanselmann

*(Released Fri, 17 Jul 2009)*
1218 bdc93557 Iustin Pop
1219 61b5e342 Michael Hanselmann
- Added experimental support for stripped logical volumes; this should
1220 61b5e342 Michael Hanselmann
  enhance performance but comes with a higher complexity in the block
1221 61b5e342 Michael Hanselmann
  device handling; stripping is only enabled when passing
1222 61b5e342 Michael Hanselmann
  ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
1223 61b5e342 Michael Hanselmann
  affected even in the non-stripped mode
1224 61b5e342 Michael Hanselmann
- Improved resiliency against transient failures at the end of DRBD
1225 61b5e342 Michael Hanselmann
  resyncs, and in general of DRBD resync checks
1226 61b5e342 Michael Hanselmann
- Fixed a couple of issues with exports and snapshot errors
1227 61b5e342 Michael Hanselmann
- Fixed a couple of issues in instance listing
1228 61b5e342 Michael Hanselmann
- Added display of the disk size in ``gnt-instance info``
1229 61b5e342 Michael Hanselmann
- Fixed checking for valid OSes in instance creation
1230 aa287e8c Michael Hanselmann
- Fixed handling of the "vcpus" parameter in instance listing and in
1231 61b5e342 Michael Hanselmann
  general of invalid parameters
1232 61b5e342 Michael Hanselmann
- Fixed http server library, and thus RAPI, to handle invalid
1233 61b5e342 Michael Hanselmann
  username/password combinations correctly; this means that now they
1234 61b5e342 Michael Hanselmann
  report unauthorized for queries too, not only for modifications,
1235 61b5e342 Michael Hanselmann
  allowing earlier detect of configuration problems
1236 aa287e8c Michael Hanselmann
- Added a new "role" node list field, equivalent to the master/master
1237 61b5e342 Michael Hanselmann
  candidate/drained/offline flags combinations
1238 61b5e342 Michael Hanselmann
- Fixed cluster modify and changes of candidate pool size
1239 61b5e342 Michael Hanselmann
- Fixed cluster verify error messages for wrong files on regular nodes
1240 61b5e342 Michael Hanselmann
- Fixed a couple of issues with node demotion from master candidate role
1241 61b5e342 Michael Hanselmann
- Fixed node readd issues
1242 61b5e342 Michael Hanselmann
- Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
1243 aa287e8c Michael Hanselmann
- Added a new ``--no-voting`` option for masterfailover to fix failover
1244 aa287e8c Michael Hanselmann
  on two-nodes clusters when the former master node is unreachable
1245 61b5e342 Michael Hanselmann
- Added instance reinstall over RAPI

1250 61b5e342 Michael Hanselmann
1251 bdc93557 Iustin Pop
*(Released Tue, 16 Jun 2009)*
1252 bdc93557 Iustin Pop
1253 61b5e342 Michael Hanselmann
- added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
1254 61b5e342 Michael Hanselmann
  allow re-adding the start in single-user option (regression from 1.2)
1255 61b5e342 Michael Hanselmann
- the watcher writes the instance status to a file, to allow monitoring
1256 61b5e342 Michael Hanselmann
  to report the instance status (from the master) based on cached
1257 61b5e342 Michael Hanselmann
  results of the watcher's queries; while this can get stale if the
1258 61b5e342 Michael Hanselmann
  watcher is being locked due to other work on the cluster, this is
1259 61b5e342 Michael Hanselmann
  still an improvement
1260 61b5e342 Michael Hanselmann
- the watcher now also restarts the node daemon and the rapi daemon if
1261 61b5e342 Michael Hanselmann
  they died
1262 61b5e342 Michael Hanselmann
- fixed the watcher to handle full and drained queue cases
1263 7faf5110 Michael Hanselmann
- hooks export more instance data in the environment, which helps if
1264 7faf5110 Michael Hanselmann
  hook scripts need to take action based on the instance's properties
1265 7faf5110 Michael Hanselmann
  (no longer need to query back into ganeti)
1266 61b5e342 Michael Hanselmann
- instance failovers when the instance is stopped do not check for free
1267 61b5e342 Michael Hanselmann
  RAM, so that failing over a stopped instance is possible in low memory
1268 61b5e342 Michael Hanselmann
  situations
1269 61b5e342 Michael Hanselmann
- rapi uses queries for tags instead of jobs (for less job traffic), and
1270 61b5e342 Michael Hanselmann
  for cluster tags it won't talk to masterd at all but read them from
1271 61b5e342 Michael Hanselmann
  ssconf
1272 61b5e342 Michael Hanselmann
- a couple of error handling fixes in RAPI
1273 61b5e342 Michael Hanselmann
- drbd handling: improved the error handling of inconsistent disks after
1274 61b5e342 Michael Hanselmann
  resync to reduce the frequency of "there are some degraded disks for
1275 61b5e342 Michael Hanselmann
  this instance" messages
1276 61b5e342 Michael Hanselmann
- fixed a bug in live migration when DRBD doesn't want to reconnect (the
1277 61b5e342 Michael Hanselmann
  error handling path called a wrong function name)

1303 bdc93557 Iustin Pop
1304 61b5e342 Michael Hanselmann
- change the OS list to not require locks; this helps with big clusters
1305 61b5e342 Michael Hanselmann
- fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
1306 61b5e342 Michael Hanselmann
  volume group is broken
1307 61b5e342 Michael Hanselmann
- ``gnt-instance info``, without any arguments, doesn't run for all
1308 61b5e342 Michael Hanselmann
  instances anymore; either pass ``--all`` or pass the desired
1309 61b5e342 Michael Hanselmann

*(Released Thu, 19 Feb 2009)*
1359 bdc93557 Iustin Pop
1360 61b5e342 Michael Hanselmann
- Xen PVM and KVM have switched the default value for the instance root
1361 61b5e342 Michael Hanselmann
  disk to the first partition on the first drive, instead of the whole
1362 61b5e342 Michael Hanselmann
  drive; this means that the OS installation scripts must be changed
1363 61b5e342 Michael Hanselmann
  accordingly
1364 61b5e342 Michael Hanselmann
- Man pages have been updated
1365 61b5e342 Michael Hanselmann
- RAPI has been switched by default to HTTPS, and the exported functions

  should all work correctly
1367 61b5e342 Michael Hanselmann
- RAPI v1 has been removed
1368 61b5e342 Michael Hanselmann

1377 bdc93557 Iustin Pop
1378 61b5e342 Michael Hanselmann
- Version 2 is a general rewrite of the code and therefore the
1379 61b5e342 Michael Hanselmann
  differences are too many to list, see the design document for 2.0 in
1380 61b5e342 Michael Hanselmann
  the ``doc/`` subdirectory for more details
1381 61b5e342 Michael Hanselmann
- In this beta version there is not yet a migration path from 1.2 (there
1382 61b5e342 Michael Hanselmann
  will be one in the final 2.0 release)
1383 61b5e342 Michael Hanselmann
- A few significant changes are:
1384 61b5e342 Michael Hanselmann
1385 61b5e342 Michael Hanselmann
  - all commands are executed by a daemon (``ganeti-masterd``) and the
1386 61b5e342 Michael Hanselmann
    various ``gnt-*`` commands are just front-ends to it
1387 7faf5110 Michael Hanselmann
  - all the commands are entered into, and executed from a job queue,
1388 7faf5110 Michael Hanselmann
    see the ``gnt-job(8)`` manpage
1389 7faf5110 Michael Hanselmann
  - the RAPI daemon supports read-write operations, secured by basic
1390 7faf5110 Michael Hanselmann
    HTTP authentication on top of HTTPS
1391 61b5e342 Michael Hanselmann
  - DRBD version 0.7 support has been removed, DRBD 8 is the only
1392 61b5e342 Michael Hanselmann
    supported version (when migrating from Ganeti 1.2 to 2.0, you need
1393 61b5e342 Michael Hanselmann
    to migrate to DRBD 8 first while still running Ganeti 1.2)
1394 61b5e342 Michael Hanselmann
  - DRBD devices are using statically allocated minor numbers, which
1395 61b5e342 Michael Hanselmann
    will be assigned to existing instances during the migration process
1396 61b5e342 Michael Hanselmann
  - there is support for both Xen PVM and Xen HVM instances running on
1397 61b5e342 Michael Hanselmann
    the same cluster
1398 61b5e342 Michael Hanselmann
  - KVM virtualization is supported too
1399 61b5e342 Michael Hanselmann
  - file-based storage has been implemented, which means that it is
1400 61b5e342 Michael Hanselmann
    possible to run the cluster without LVM and DRBD storage, for
1401 61b5e342 Michael Hanselmann
    example using a shared filesystem exported from shared storage (and
1402 61b5e342 Michael Hanselmann
    still have live migration)

1423 61b5e342 Michael Hanselmann
  ``gnt-node list``
1424 61b5e342 Michael Hanselmann
- Support OSes that handle more than one version of the OS api (but do
1425 61b5e342 Michael Hanselmann
  not change the current API in any other way)
1426 61b5e342 Michael Hanselmann

  type of disk exported to fully virtualized instances.
1439 61b5e342 Michael Hanselmann
- provide access to the serial console of HVM instances
1440 7faf5110 Michael Hanselmann
- instance auto_balance flag, set by default. If turned off it will
1441 7faf5110 Michael Hanselmann
  avoid warnings on cluster verify if there is not enough memory to fail
1442 7faf5110 Michael Hanselmann
  over an instance. in the future it will prevent automatically failing
1443 7faf5110 Michael Hanselmann
  it over when we will support that.
1444 61b5e342 Michael Hanselmann
- batcher tool for instance creation, see ``tools/README.batcher``
1445 61b5e342 Michael Hanselmann
- ``gnt-instance reinstall --select-os`` to interactively select a new
1446 61b5e342 Michael Hanselmann
  operating system when reinstalling an instance.
1447 61b5e342 Michael Hanselmann
- when changing the memory amount on instance modify a check has been
1448 61b5e342 Michael Hanselmann
  added that the instance will be able to start. also warnings are
1449 61b5e342 Michael Hanselmann
  emitted if the instance will not be able to fail over, if auto_balance
1450 61b5e342 Michael Hanselmann
  is true.

*(Released Fri, 13 Jun 2008)*
1480 bdc93557 Iustin Pop
1481 61b5e342 Michael Hanselmann
- Experimental readonly, REST-based remote API implementation;
1482 61b5e342 Michael Hanselmann
  automatically started on master node, TCP port 5080, if enabled by
1483 61b5e342 Michael Hanselmann
  ``--enable-rapi`` parameter to configure script.
1484 61b5e342 Michael Hanselmann
- Instance allocator support. Add and import instance accept a
1485 61b5e342 Michael Hanselmann
  ``--iallocator`` parameter, and call that instance allocator to decide
1486 61b5e342 Michael Hanselmann
  which node to use for the instance. The iallocator document describes
1487 61b5e342 Michael Hanselmann
  what's expected from an allocator script.
1488 61b5e342 Michael Hanselmann
- ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
1489 61b5e342 Michael Hanselmann
  ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
1490 61b5e342 Michael Hanselmann
  node is lost there is still enough memory to fail over the instances
1491 61b5e342 Michael Hanselmann
  that reside on it.
1492 61b5e342 Michael Hanselmann
- ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
1493 61b5e342 Michael Hanselmann
  ``gnt-cluster verify``, to check for site-specific compliance. All the
1494 61b5e342 Michael Hanselmann
  hooks will run, and their output, if any, will be displayed. Any
1495 61b5e342 Michael Hanselmann
  failing hook will make the verification return an error value.
1496 61b5e342 Michael Hanselmann
- ``gnt-cluster verify`` now checks that its peers are reachable on the
1497 61b5e342 Michael Hanselmann
  primary and secondary interfaces
1498 61b5e342 Michael Hanselmann
- ``gnt-node add`` now supports the ``--readd`` option, to readd a node
1499 61b5e342 Michael Hanselmann
  that is still declared as part of the cluster and has failed.
1500 61b5e342 Michael Hanselmann
- ``gnt-* list`` commands now accept a new ``-o +field`` way of
1501 61b5e342 Michael Hanselmann
  specifying output fields, that just adds the chosen fields to the
1502 61b5e342 Michael Hanselmann
  default ones.
1503 61b5e342 Michael Hanselmann
- ``gnt-backup`` now has a new ``remove`` command to delete an existing
1504 61b5e342 Michael Hanselmann
  export from the filesystem.
1505 61b5e342 Michael Hanselmann
- New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
1506 61b5e342 Michael Hanselmann
  have been added. Using them you can enable/disable acpi and pae
1507 61b5e342 Michael Hanselmann
  support, and specify a path for a cd image to be exported to the
1508 61b5e342 Michael Hanselmann
  instance. These parameters as the name suggest only work on HVM
1509 61b5e342 Michael Hanselmann
  clusters.
1510 61b5e342 Michael Hanselmann
- When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
1511 61b5e342 Michael Hanselmann
  PAE support will be set to the previously hardcoded values, but the
1512 61b5e342 Michael Hanselmann
  (previously hardcoded) path to the CDROM ISO image will be unset and
1513 61b5e342 Michael Hanselmann
  if required, needs to be set manually with ``gnt-instance modify``
1514 61b5e342 Michael Hanselmann
  after the upgrade.
1515 61b5e342 Michael Hanselmann
- The address to which an instance's VNC console is bound is now
1516 61b5e342 Michael Hanselmann
  selectable per-instance, rather than being cluster wide. Of course
1517 61b5e342 Michael Hanselmann
  this only applies to instances controlled via VNC, so currently just
1518 61b5e342 Michael Hanselmann
  applies to HVM clusters.
