4 | ba538816 | Iustin Pop | Version 2.1.2 |
5 | ba538816 | Iustin Pop | ------------- |
6 | ba538816 | Iustin Pop | |
7 | ace6cbe8 | Iustin Pop | *(Released Fri, 7 May 2010)* |
8 | ba538816 | Iustin Pop | |
9 | ba538816 | Iustin Pop | Another release with a long development cycle, during which many |
10 | ba538816 | Iustin Pop | different features were added. |
11 | ba538816 | Iustin Pop | |
12 | ba538816 | Iustin Pop | Significant features |
13 | ba538816 | Iustin Pop | ~~~~~~~~~~~~~~~~~~~~ |
14 | ba538816 | Iustin Pop | |
15 | ba538816 | Iustin Pop | The KVM hypervisor now can run the individual instances as non-root, to |
16 | ba538816 | Iustin Pop | reduce the impact of a VM being hijacked due to bugs in the |
17 | ba538816 | Iustin Pop | hypervisor. It is possible to run all instances as a single (non-root) |
18 | ba538816 | Iustin Pop | user, to manually specify a user for each instance, or to dynamically |
19 | ba538816 | Iustin Pop | allocate a user out of a cluster-wide pool to each instance, with the |
20 | ba538816 | Iustin Pop | guarantee that no two instances will run under the same user ID on any |
21 | ba538816 | Iustin Pop | given node. |
22 | ba538816 | Iustin Pop | |
23 | ba538816 | Iustin Pop | An experimental RAPI client library, that can be used standalone |
24 | ba538816 | Iustin Pop | (without the other Ganeti libraries), is provided in the source tree as |
25 | ba538816 | Iustin Pop | ``lib/rapi/client.py``. Note this client might change its interface in |
26 | ba538816 | Iustin Pop | the future, as we iterate on its capabilities. |
27 | ba538816 | Iustin Pop | |
28 | ba538816 | Iustin Pop | A new command, ``gnt-cluster renew-crypto`` has been added to easily |
29 | ba538816 | Iustin Pop | replace the cluster's certificates and crypto keys. This might help in |
30 | ba538816 | Iustin Pop | case they have been compromised, or have simply expired. |
31 | ba538816 | Iustin Pop | |
32 | ba538816 | Iustin Pop | A new disk option for instance creation has been added that allows one |
33 | ba538816 | Iustin Pop | to "adopt" currently existing logical volumes, with data |
34 | ba538816 | Iustin Pop | preservation. This should allow easier migration to Ganeti from |
35 | ba538816 | Iustin Pop | unmanaged (or managed via other software) instances. |
36 | ba538816 | Iustin Pop | |
37 | ba538816 | Iustin Pop | Another disk improvement is the possibility to convert between redundant |
38 | ba538816 | Iustin Pop | (DRBD) and plain (LVM) disk configuration for an instance. This should |
39 | ba538816 | Iustin Pop | allow better scalability (starting with one node and growing the |
40 | ba538816 | Iustin Pop | cluster, or shrinking a two-node cluster to one node). |
41 | ba538816 | Iustin Pop | |
42 | ba538816 | Iustin Pop | A new feature that could help with automated node failovers has been |
43 | ba538816 | Iustin Pop | implemented: if a node sees itself as offline (by querying the master |
44 | ba538816 | Iustin Pop | candidates), it will try to shutdown (hard) all instances and any active |
45 | ba538816 | Iustin Pop | DRBD devices. This reduces the risk of duplicate instances if an |
46 | ba538816 | Iustin Pop | external script automatically failovers the instances on such nodes. To |
47 | ba538816 | Iustin Pop | enable this, the cluster parameter ``maintain_node_health`` should be |
48 | ba538816 | Iustin Pop | enabled; in the future this option (per the name) will enable other |
49 | ba538816 | Iustin Pop | automatic maintenance features. |
50 | ba538816 | Iustin Pop | |
51 | ba538816 | Iustin Pop | Instance export/import now will reuse the original instance |
52 | ba538816 | Iustin Pop | specifications for all parameters; that means exporting an instance, |
53 | ba538816 | Iustin Pop | deleting it and the importing it back should give an almost identical |
54 | ba538816 | Iustin Pop | instance. Note that the default import behaviour has changed from |
55 | ba538816 | Iustin Pop | before, where it created only one NIC; now it recreates the original |
56 | ba538816 | Iustin Pop | number of NICs. |
57 | ba538816 | Iustin Pop | |
58 | ba538816 | Iustin Pop | Cluster verify has added a few new checks: SSL certificates validity, |
59 | ba538816 | Iustin Pop | /etc/hosts consistency across the cluster, etc. |
60 | ba538816 | Iustin Pop | |
61 | ba538816 | Iustin Pop | Other changes |
62 | ba538816 | Iustin Pop | ~~~~~~~~~~~~~ |
63 | ba538816 | Iustin Pop | |
64 | ba538816 | Iustin Pop | As usual, many internal changes were done, documentation fixes, |
65 | ba538816 | Iustin Pop | etc. Among others: |
66 | ba538816 | Iustin Pop | |
67 | ba538816 | Iustin Pop | - Fixed cluster initialization with disabled cluster storage (regression |
68 | ba538816 | Iustin Pop | introduced in 2.1.1) |
69 | ba538816 | Iustin Pop | - File-based storage supports growing the disks |
70 | ba538816 | Iustin Pop | - Fixed behaviour of node role changes |
71 | ba538816 | Iustin Pop | - Fixed cluster verify for some corner cases, plus a general rewrite of |
72 | ba538816 | Iustin Pop | cluster verify to allow future extension with more checks |
73 | ba538816 | Iustin Pop | - Fixed log spamming by watcher and node daemon (regression introduced |
74 | ba538816 | Iustin Pop | in 2.1.1) |
75 | ba538816 | Iustin Pop | - Fixed possible validation issues when changing the list of enabled |
76 | ba538816 | Iustin Pop | hypervisors |
77 | ba538816 | Iustin Pop | - Fixed cleanup of /etc/hosts during node removal |
78 | ba538816 | Iustin Pop | - Fixed RAPI response for invalid methods |
79 | ba538816 | Iustin Pop | - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon |
80 | ba538816 | Iustin Pop | - Multiple small improvements to the KVM hypervisor (VNC usage, booting |
81 | ba538816 | Iustin Pop | from ide disks, etc.) |
82 | ba538816 | Iustin Pop | - Allow OS changes without re-installation (to record a changed OS |
83 | ba538816 | Iustin Pop | outside of Ganeti, or to allow OS renames) |
84 | ba538816 | Iustin Pop | - Allow instance creation without OS installation (useful for example if |
85 | ba538816 | Iustin Pop | the OS will be installed manually, or restored from a backup not in |
86 | ba538816 | Iustin Pop | Ganeti format) |
87 | ba538816 | Iustin Pop | - Implemented option to make cluster ``copyfile`` use the replication |
88 | ba538816 | Iustin Pop | network |
89 | ba538816 | Iustin Pop | - Added list of enabled hypervisors to ssconf (possibly useful for |
90 | ba538816 | Iustin Pop | external scripts) |
91 | ba538816 | Iustin Pop | - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from |
92 | ba538816 | Iustin Pop | 1.2 clusters |
93 | ba538816 | Iustin Pop | - A partial form of node re-IP is possible via node readd, which now |
94 | ba538816 | Iustin Pop | allows changed node primary IP |
95 | ba538816 | Iustin Pop | - Command line utilities now show an informational message if the job is |
96 | ba538816 | Iustin Pop | waiting for a lock |
97 | ba538816 | Iustin Pop | - The logs of the master daemon now show the PID/UID/GID of the |
98 | ba538816 | Iustin Pop | connected client |
99 | ba538816 | Iustin Pop | |
100 | ba538816 | Iustin Pop | |

102 | c655522d | Iustin Pop | Version 2.1.1 |
103 | c655522d | Iustin Pop | ------------- |
104 | c655522d | Iustin Pop | |
105 | bdc93557 | Iustin Pop | *(Released Fri, 12 Mar 2010)* |
106 | bdc93557 | Iustin Pop | |
107 | c655522d | Iustin Pop | During the 2.1.0 long release candidate cycle, a lot of improvements and |
108 | c655522d | Iustin Pop | changes have accumulated with were released later as 2.1.1. |
109 | c655522d | Iustin Pop | |
110 | c655522d | Iustin Pop | Major changes |
111 | c655522d | Iustin Pop | ~~~~~~~~~~~~~ |
112 | c655522d | Iustin Pop | |
113 | c655522d | Iustin Pop | The node evacuate command (``gnt-node evacuate``) was significantly |
114 | c655522d | Iustin Pop | rewritten, and as such the IAllocator protocol was changed - a new |
115 | c655522d | Iustin Pop | request type has been added. This unfortunate change during a stable |
116 | c655522d | Iustin Pop | series is designed to improve performance of node evacuations; on |
117 | c655522d | Iustin Pop | clusters with more than about five nodes and which are well-balanced, |
118 | c655522d | Iustin Pop | evacuation should proceed in parallel for all instances of the node |
119 | c655522d | Iustin Pop | being evacuated. As such, any existing IAllocator scripts need to be |
120 | c655522d | Iustin Pop | updated, otherwise the above command will fail due to the unknown |
121 | c655522d | Iustin Pop | request. The provided "dumb" allocator has not been updated; but the |
122 | c655522d | Iustin Pop | ganeti-htools package supports the new protocol since version 0.2.4. |
123 | c655522d | Iustin Pop | |
124 | c655522d | Iustin Pop | Another important change is increased validation of node and instance |
125 | c655522d | Iustin Pop | names. This might create problems in special cases, if invalid host |
126 | c655522d | Iustin Pop | names are being used. |
127 | c655522d | Iustin Pop | |
128 | c655522d | Iustin Pop | Also, a new layer of hypervisor parameters has been added, that sits at |
129 | c655522d | Iustin Pop | OS level between the cluster defaults and the instance ones. This allows |
130 | c655522d | Iustin Pop | customisation of virtualization parameters depending on the installed |
131 | c655522d | Iustin Pop | OS. For example instances with OS 'X' may have a different KVM kernel |
132 | c655522d | Iustin Pop | (or any other parameter) than the cluster defaults. This is intended to |
133 | c655522d | Iustin Pop | help managing a multiple OSes on the same cluster, without manual |
134 | c655522d | Iustin Pop | modification of each instance's parameters. |
135 | c655522d | Iustin Pop | |
136 | c655522d | Iustin Pop | A tool for merging clusters, ``cluster-merge``, has been added in the |
137 | c655522d | Iustin Pop | tools sub-directory. |
138 | c655522d | Iustin Pop | |
139 | c655522d | Iustin Pop | Bug fixes |
140 | c655522d | Iustin Pop | ~~~~~~~~~ |
141 | c655522d | Iustin Pop | |
142 | c655522d | Iustin Pop | - Improved the int/float conversions that should make the code more |
143 | c655522d | Iustin Pop | robust in face of errors from the node daemons |
144 | c655522d | Iustin Pop | - Fixed the remove node code in case of internal configuration errors |
145 | c655522d | Iustin Pop | - Fixed the node daemon behaviour in face of inconsistent queue |
146 | c655522d | Iustin Pop | directory (e.g. read-only file-system where we can't open the files |
147 | c655522d | Iustin Pop | read-write, etc.) |
148 | c655522d | Iustin Pop | - Fixed the behaviour of gnt-node modify for master candidate demotion; |
149 | c655522d | Iustin Pop | now it either aborts cleanly or, if given the new “auto_promote” |
150 | c655522d | Iustin Pop | parameter, will automatically promote other nodes as needed |
151 | c655522d | Iustin Pop | - Fixed compatibility with (unreleased yet) Python 2.6.5 that would |
152 | c655522d | Iustin Pop | completely prevent Ganeti from working |
153 | c655522d | Iustin Pop | - Fixed bug for instance export when not all disks were successfully |
154 | c655522d | Iustin Pop | exported |
155 | c655522d | Iustin Pop | - Fixed behaviour of node add when the new node is slow in starting up |
156 | c655522d | Iustin Pop | the node daemon |
157 | c655522d | Iustin Pop | - Fixed handling of signals in the LUXI client, which should improve |
158 | c655522d | Iustin Pop | behaviour of command-line scripts |
159 | c655522d | Iustin Pop | - Added checks for invalid node/instance names in the configuration (now |
160 | c655522d | Iustin Pop | flagged during cluster verify) |
161 | c655522d | Iustin Pop | - Fixed watcher behaviour for disk activation errors |
162 | c655522d | Iustin Pop | - Fixed two potentially endless loops in http library, which led to the |
163 | c655522d | Iustin Pop | RAPI daemon hanging and consuming 100% CPU in some cases |
164 | c655522d | Iustin Pop | - Fixed bug in RAPI daemon related to hashed passwords |
165 | c655522d | Iustin Pop | - Fixed bug for unintended qemu-level bridging of multi-NIC KVM |
166 | c655522d | Iustin Pop | instances |
167 | c655522d | Iustin Pop | - Enhanced compatibility with non-Debian OSes, but not using absolute |
168 | c655522d | Iustin Pop | path in some commands and allowing customisation of the ssh |
169 | c655522d | Iustin Pop | configuration directory |
170 | c655522d | Iustin Pop | - Fixed possible future issue with new Python versions by abiding to the |
171 | c655522d | Iustin Pop | proper use of ``__slots__`` attribute on classes |
172 | c655522d | Iustin Pop | - Added checks that should prevent directory traversal attacks |
173 | c655522d | Iustin Pop | - Many documentation fixes based on feedback from users |
174 | c655522d | Iustin Pop | |
175 | c655522d | Iustin Pop | New features |
176 | c655522d | Iustin Pop | ~~~~~~~~~~~~ |
177 | c655522d | Iustin Pop | |
178 | c655522d | Iustin Pop | - Added an “early_release” more for instance replace disks and node |
179 | c655522d | Iustin Pop | evacuate, where we release locks earlier and thus allow higher |
180 | c655522d | Iustin Pop | parallelism within the cluster |
181 | c655522d | Iustin Pop | - Added watcher hooks, intended to allow the watcher to restart other |
182 | c655522d | Iustin Pop | daemons (e.g. from the ganeti-nbma project), but they can be used of |
183 | c655522d | Iustin Pop | course for any other purpose |
184 | c655522d | Iustin Pop | - Added a compile-time disable for DRBD barriers, to increase |
185 | c655522d | Iustin Pop | performance if the administrator trusts the power supply or the |
186 | c655522d | Iustin Pop | storage system to not lose writes |
187 | c655522d | Iustin Pop | - Added the option of using syslog for logging instead of, or in |
188 | c655522d | Iustin Pop | addition to, Ganeti's own log files |
189 | c655522d | Iustin Pop | - Removed boot restriction for paravirtual NICs for KVM, recent versions |
190 | c655522d | Iustin Pop | can indeed boot from a paravirtual NIC |
191 | c655522d | Iustin Pop | - Added a generic debug level for many operations; while this is not |
192 | c655522d | Iustin Pop | used widely yet, it allows one to pass the debug value all the way to |
193 | c655522d | Iustin Pop | the OS scripts |
194 | c655522d | Iustin Pop | - Enhanced the hooks environment for instance moves (failovers, |
195 | c655522d | Iustin Pop | migrations) where the primary/secondary nodes changed during the |
196 | c655522d | Iustin Pop | operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars |
197 | c655522d | Iustin Pop | - Enhanced data validations for many user-supplied values; one important |
198 | c655522d | Iustin Pop | item is the restrictions imposed on instance and node names, which |
199 | c655522d | Iustin Pop | might reject some (invalid) host names |
200 | c655522d | Iustin Pop | - Add a configure-time option to disable file-based storage, if it's not |
201 | c655522d | Iustin Pop | needed; this allows greater security separation between the master |
202 | c655522d | Iustin Pop | node and the other nodes from the point of view of the inter-node RPC |
203 | c655522d | Iustin Pop | protocol |
204 | c655522d | Iustin Pop | - Added user notification in interactive tools if job is waiting in the |
205 | c655522d | Iustin Pop | job queue or trying to acquire locks |
206 | c655522d | Iustin Pop | - Added log messages when a job is waiting for locks |
207 | c655522d | Iustin Pop | - Added filtering by node tags in instance operations which admit |
208 | c655522d | Iustin Pop | multiple instances (start, stop, reboot, reinstall) |
209 | c655522d | Iustin Pop | - Added a new tool for cluster mergers, ``cluster-merge`` |
210 | c655522d | Iustin Pop | - Parameters from command line which are of the form ``a=b,c=d`` can now |
211 | c655522d | Iustin Pop | use backslash escapes to pass in values which contain commas, |
212 | c655522d | Iustin Pop | e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value |
213 | c655522d | Iustin Pop | ``b,c`` |
214 | c655522d | Iustin Pop | - For KVM, the instance name is the first parameter passed to KVM, so |
215 | c655522d | Iustin Pop | that it's more visible in the process list |
216 | c655522d | Iustin Pop | |
217 | c655522d | Iustin Pop | |
218 | 920a91bf | Michael Hanselmann | Version 2.1.0 |

228 | 920a91bf | Michael Hanselmann | - Instance NICs can now be routed instead of being associated with a |
229 | 920a91bf | Michael Hanselmann | networking bridge |
230 | 920a91bf | Michael Hanselmann | - Improved job locking logic to reduce impact of jobs acquiring multiple |
231 | 920a91bf | Michael Hanselmann | locks waiting for other long-running jobs |
232 | 920a91bf | Michael Hanselmann | |
233 | bfe61b0b | Iustin Pop | In-depth implementation details can be found in the Ganeti 2.1 design |

388 | 61b5e342 | Michael Hanselmann | |
389 | bdc93557 | Iustin Pop | *(Released Fri, 7 Aug 2009)* |
390 | bdc93557 | Iustin Pop | |
391 | 61b5e342 | Michael Hanselmann | - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command |
392 | 61b5e342 | Michael Hanselmann | to allow using the pre-2.0.2 behaviour in activation, if any existing |
393 | 61b5e342 | Michael Hanselmann | instances have mismatched disk sizes in the configuration |
394 | 7faf5110 | Michael Hanselmann | - Added ``gnt-cluster repair-disk-sizes`` command to check and update |
395 | 7faf5110 | Michael Hanselmann | any configuration mismatches for disk sizes |
396 | 61b5e342 | Michael Hanselmann | - Added ``gnt-master cluste-failover --no-voting`` to allow master |

407 | bdc93557 | Iustin Pop | *(Released Fri, 17 Jul 2009)* |
408 | bdc93557 | Iustin Pop | |
409 | 61b5e342 | Michael Hanselmann | - Added experimental support for stripped logical volumes; this should |
410 | 61b5e342 | Michael Hanselmann | enhance performance but comes with a higher complexity in the block |
411 | 61b5e342 | Michael Hanselmann | device handling; stripping is only enabled when passing |
412 | 61b5e342 | Michael Hanselmann | ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are |
413 | 61b5e342 | Michael Hanselmann | affected even in the non-stripped mode |
414 | 61b5e342 | Michael Hanselmann | - Improved resiliency against transient failures at the end of DRBD |
415 | 61b5e342 | Michael Hanselmann | resyncs, and in general of DRBD resync checks |

419 | 61b5e342 | Michael Hanselmann | - Fixed checking for valid OSes in instance creation |
420 | aa287e8c | Michael Hanselmann | - Fixed handling of the "vcpus" parameter in instance listing and in |
421 | 61b5e342 | Michael Hanselmann | general of invalid parameters |
422 | 61b5e342 | Michael Hanselmann | - Fixed http server library, and thus RAPI, to handle invalid |
423 | 61b5e342 | Michael Hanselmann | username/password combinations correctly; this means that now they |
424 | 61b5e342 | Michael Hanselmann | report unauthorized for queries too, not only for modifications, |
425 | 61b5e342 | Michael Hanselmann | allowing earlier detect of configuration problems |
426 | aa287e8c | Michael Hanselmann | - Added a new "role" node list field, equivalent to the master/master |
427 | 61b5e342 | Michael Hanselmann | candidate/drained/offline flags combinations |

432 | 61b5e342 | Michael Hanselmann | - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup |
433 | aa287e8c | Michael Hanselmann | - Added a new ``--no-voting`` option for masterfailover to fix failover |
434 | aa287e8c | Michael Hanselmann | on two-nodes clusters when the former master node is unreachable |
435 | 61b5e342 | Michael Hanselmann | - Added instance reinstall over RAPI |

440 | 61b5e342 | Michael Hanselmann | |
441 | bdc93557 | Iustin Pop | *(Released Tue, 16 Jun 2009)* |
442 | bdc93557 | Iustin Pop | |
443 | 61b5e342 | Michael Hanselmann | - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will |
444 | 61b5e342 | Michael Hanselmann | allow re-adding the start in single-user option (regression from 1.2) |
445 | 61b5e342 | Michael Hanselmann | - the watcher writes the instance status to a file, to allow monitoring |
446 | 61b5e342 | Michael Hanselmann | to report the instance status (from the master) based on cached |
447 | 61b5e342 | Michael Hanselmann | results of the watcher's queries; while this can get stale if the |
448 | 61b5e342 | Michael Hanselmann | watcher is being locked due to other work on the cluster, this is |
449 | 61b5e342 | Michael Hanselmann | still an improvement |
450 | 61b5e342 | Michael Hanselmann | - the watcher now also restarts the node daemon and the rapi daemon if |
451 | 61b5e342 | Michael Hanselmann | they died |
452 | 61b5e342 | Michael Hanselmann | - fixed the watcher to handle full and drained queue cases |
453 | 7faf5110 | Michael Hanselmann | - hooks export more instance data in the environment, which helps if |
454 | 7faf5110 | Michael Hanselmann | hook scripts need to take action based on the instance's properties |
455 | 7faf5110 | Michael Hanselmann | (no longer need to query back into ganeti) |
456 | 61b5e342 | Michael Hanselmann | - instance failovers when the instance is stopped do not check for free |
457 | 61b5e342 | Michael Hanselmann | RAM, so that failing over a stopped instance is possible in low memory |
458 | 61b5e342 | Michael Hanselmann | situations |
459 | 61b5e342 | Michael Hanselmann | - rapi uses queries for tags instead of jobs (for less job traffic), and |
460 | 61b5e342 | Michael Hanselmann | for cluster tags it won't talk to masterd at all but read them from |
461 | 61b5e342 | Michael Hanselmann | ssconf |
462 | 61b5e342 | Michael Hanselmann | - a couple of error handling fixes in RAPI |
463 | 61b5e342 | Michael Hanselmann | - drbd handling: improved the error handling of inconsistent disks after |
464 | 61b5e342 | Michael Hanselmann | resync to reduce the frequency of "there are some degraded disks for |
465 | 61b5e342 | Michael Hanselmann | this instance" messages |
466 | 61b5e342 | Michael Hanselmann | - fixed a bug in live migration when DRBD doesn't want to reconnect (the |
467 | 61b5e342 | Michael Hanselmann | error handling path called a wrong function name) |

496 | 61b5e342 | Michael Hanselmann | volume group is broken |
497 | 61b5e342 | Michael Hanselmann | - ``gnt-instance info``, without any arguments, doesn't run for all |
498 | 61b5e342 | Michael Hanselmann | instances anymore; either pass ``--all`` or pass the desired |
499 | 61b5e342 | Michael Hanselmann | instances; this helps against mistakes on big clusters where listing |

549 | bdc93557 | Iustin Pop | |
550 | 61b5e342 | Michael Hanselmann | - Xen PVM and KVM have switched the default value for the instance root |
551 | 61b5e342 | Michael Hanselmann | disk to the first partition on the first drive, instead of the whole |
552 | 61b5e342 | Michael Hanselmann | drive; this means that the OS installation scripts must be changed |
553 | 61b5e342 | Michael Hanselmann | accordingly |
554 | 61b5e342 | Michael Hanselmann | - Man pages have been updated |
555 | 61b5e342 | Michael Hanselmann | - RAPI has been switched by default to HTTPS, and the exported functions |
556 | 61b5e342 | Michael Hanselmann | should all work correctly |
557 | 61b5e342 | Michael Hanselmann | - RAPI v1 has been removed |
558 | 61b5e342 | Michael Hanselmann | - Many improvements to the KVM hypervisor |
559 | 61b5e342 | Michael Hanselmann | - Block device errors are now better reported |
560 | 61b5e342 | Michael Hanselmann | - Many other bugfixes and small improvements |

563 | 10f31783 | Iustin Pop | Version 2.0 beta 1 |
564 | 61b5e342 | Michael Hanselmann | ------------------ |
565 | 61b5e342 | Michael Hanselmann | |
566 | bdc93557 | Iustin Pop | *(Released Mon, 26 Jan 2009)* |
567 | bdc93557 | Iustin Pop | |
568 | 61b5e342 | Michael Hanselmann | - Version 2 is a general rewrite of the code and therefore the |
569 | 61b5e342 | Michael Hanselmann | differences are too many to list, see the design document for 2.0 in |
570 | 61b5e342 | Michael Hanselmann | the ``doc/`` subdirectory for more details |
571 | 61b5e342 | Michael Hanselmann | - In this beta version there is not yet a migration path from 1.2 (there |
572 | 61b5e342 | Michael Hanselmann | will be one in the final 2.0 release) |
573 | 61b5e342 | Michael Hanselmann | - A few significant changes are: |
574 | 61b5e342 | Michael Hanselmann | |
575 | 61b5e342 | Michael Hanselmann | - all commands are executed by a daemon (``ganeti-masterd``) and the |
576 | 61b5e342 | Michael Hanselmann | various ``gnt-*`` commands are just front-ends to it |
577 | 7faf5110 | Michael Hanselmann | - all the commands are entered into, and executed from a job queue, |
578 | 7faf5110 | Michael Hanselmann | see the ``gnt-job(8)`` manpage |
579 | 7faf5110 | Michael Hanselmann | - the RAPI daemon supports read-write operations, secured by basic |
580 | 7faf5110 | Michael Hanselmann | HTTP authentication on top of HTTPS |
581 | 61b5e342 | Michael Hanselmann | - DRBD version 0.7 support has been removed, DRBD 8 is the only |
582 | 61b5e342 | Michael Hanselmann | supported version (when migrating from Ganeti 1.2 to 2.0, you need |
583 | 61b5e342 | Michael Hanselmann | to migrate to DRBD 8 first while still running Ganeti 1.2) |
584 | 61b5e342 | Michael Hanselmann | - DRBD devices are using statically allocated minor numbers, which |
585 | 61b5e342 | Michael Hanselmann | will be assigned to existing instances during the migration process |
586 | 61b5e342 | Michael Hanselmann | - there is support for both Xen PVM and Xen HVM instances running on |
587 | 61b5e342 | Michael Hanselmann | the same cluster |
588 | 61b5e342 | Michael Hanselmann | - KVM virtualization is supported too |
589 | 61b5e342 | Michael Hanselmann | - file-based storage has been implemented, which means that it is |
590 | 61b5e342 | Michael Hanselmann | possible to run the cluster without LVM and DRBD storage, for |
591 | 61b5e342 | Michael Hanselmann | example using a shared filesystem exported from shared storage (and |
592 | 61b5e342 | Michael Hanselmann | still have live migration) |

601 | 61b5e342 | Michael Hanselmann | - Reuse the old instance mac address by default on instance import, if |
602 | 61b5e342 | Michael Hanselmann | the instance name is the same. |
603 | 7faf5110 | Michael Hanselmann | - Handle situations in which the node info rpc returns incomplete |
604 | 7faf5110 | Michael Hanselmann | results (issue 46) |
605 | 61b5e342 | Michael Hanselmann | - Add checks for tcp/udp ports collisions in ``gnt-cluster verify`` |

611 | 61b5e342 | Michael Hanselmann | |
612 | 61b5e342 | Michael Hanselmann | - Add an option to show the number of cpu sockets and nodes in |
613 | 61b5e342 | Michael Hanselmann | ``gnt-node list`` |
614 | 61b5e342 | Michael Hanselmann | - Support OSes that handle more than one version of the OS api (but do |
615 | 61b5e342 | Michael Hanselmann | not change the current API in any other way) |
616 | 61b5e342 | Michael Hanselmann | - Fix ``gnt-node migrate`` |

625 | bdc93557 | Iustin Pop | *(Released Wed, 24 Sep 2008)* |
626 | bdc93557 | Iustin Pop | |
627 | 61b5e342 | Michael Hanselmann | - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the |
628 | 61b5e342 | Michael Hanselmann | type of disk exported to fully virtualized instances. |
629 | 61b5e342 | Michael Hanselmann | - provide access to the serial console of HVM instances |
630 | 7faf5110 | Michael Hanselmann | - instance auto_balance flag, set by default. If turned off it will |
631 | 7faf5110 | Michael Hanselmann | avoid warnings on cluster verify if there is not enough memory to fail |
632 | 7faf5110 | Michael Hanselmann | over an instance. in the future it will prevent automatically failing |
633 | 7faf5110 | Michael Hanselmann | it over when we will support that. |
634 | 61b5e342 | Michael Hanselmann | - batcher tool for instance creation, see ``tools/README.batcher`` |
635 | 61b5e342 | Michael Hanselmann | - ``gnt-instance reinstall --select-os`` to interactively select a new |
636 | 61b5e342 | Michael Hanselmann | operating system when reinstalling an instance. |
637 | 61b5e342 | Michael Hanselmann | - when changing the memory amount on instance modify a check has been |
638 | 61b5e342 | Michael Hanselmann | added that the instance will be able to start. also warnings are |
639 | 61b5e342 | Michael Hanselmann | emitted if the instance will not be able to fail over, if auto_balance |
640 | 61b5e342 | Michael Hanselmann | is true. |
641 | 61b5e342 | Michael Hanselmann | - documentation fixes |
642 | 61b5e342 | Michael Hanselmann | - sync fields between ``gnt-instance list/modify/add/import`` |
643 | 61b5e342 | Michael Hanselmann | - fix a race condition in drbd when the sync speed was set after giving |
644 | 61b5e342 | Michael Hanselmann | the device a remote peer. |
645 | 61b5e342 | Michael Hanselmann | |

650 | bdc93557 | Iustin Pop | *(Released Tue, 22 Jul 2008)* |
651 | bdc93557 | Iustin Pop | |
652 | 61b5e342 | Michael Hanselmann | - note: the allowed size and number of tags per object were reduced |
653 | 61b5e342 | Michael Hanselmann | - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups |
654 | 61b5e342 | Michael Hanselmann | - fixed twisted 8.x compatibility |
655 | 61b5e342 | Michael Hanselmann | - fixed ``gnt-instance replace-disks`` with iallocator |
656 | 61b5e342 | Michael Hanselmann | - add TCP keepalives on twisted connections to detect restarted nodes |
657 | 61b5e342 | Michael Hanselmann | - disk increase support, see ``gnt-instance grow-disk`` |
658 | 61b5e342 | Michael Hanselmann | - implement bulk node/instance query for RAPI |
659 | 61b5e342 | Michael Hanselmann | - add tags in node/instance listing (optional) |
660 | 61b5e342 | Michael Hanselmann | - experimental migration (and live migration) support, read the man page |
661 | 61b5e342 | Michael Hanselmann | for ``gnt-instance migrate`` |
662 | 61b5e342 | Michael Hanselmann | - the ``ganeti-watcher`` logs are now timestamped, and the watcher also |
663 | 61b5e342 | Michael Hanselmann | has some small improvements in handling its state file |
664 | 61b5e342 | Michael Hanselmann | |
665 | 10f31783 | Iustin Pop | |
666 | 10f31783 | Iustin Pop | Version 1.2.4 |
667 | 61b5e342 | Michael Hanselmann | ------------- |
668 | 61b5e342 | Michael Hanselmann | |
669 | bdc93557 | Iustin Pop | *(Released Fri, 13 Jun 2008)* |
670 | bdc93557 | Iustin Pop | |
671 | 61b5e342 | Michael Hanselmann | - Experimental readonly, REST-based remote API implementation; |
672 | 61b5e342 | Michael Hanselmann | automatically started on master node, TCP port 5080, if enabled by |
673 | 61b5e342 | Michael Hanselmann | ``--enable-rapi`` parameter to configure script. |
674 | 61b5e342 | Michael Hanselmann | - Instance allocator support. Add and import instance accept a |
675 | 61b5e342 | Michael Hanselmann | ``--iallocator`` parameter, and call that instance allocator to decide |
676 | 61b5e342 | Michael Hanselmann | which node to use for the instance. The iallocator document describes |
677 | 61b5e342 | Michael Hanselmann | what's expected from an allocator script. |
678 | 61b5e342 | Michael Hanselmann | - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the |
679 | 61b5e342 | Michael Hanselmann | ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a |
680 | 61b5e342 | Michael Hanselmann | node is lost there is still enough memory to fail over the instances |
681 | 61b5e342 | Michael Hanselmann | that reside on it. |
682 | 61b5e342 | Michael Hanselmann | - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to |
683 | 61b5e342 | Michael Hanselmann | ``gnt-cluster verify``, to check for site-specific compliance. All the |
684 | 61b5e342 | Michael Hanselmann | hooks will run, and their output, if any, will be displayed. Any |
685 | 61b5e342 | Michael Hanselmann | failing hook will make the verification return an error value. |
686 | 61b5e342 | Michael Hanselmann | - ``gnt-cluster verify`` now checks that its peers are reachable on the |
687 | 61b5e342 | Michael Hanselmann | primary and secondary interfaces |
688 | 61b5e342 | Michael Hanselmann | - ``gnt-node add`` now supports the ``--readd`` option, to readd a node |
689 | 61b5e342 | Michael Hanselmann | that is still declared as part of the cluster and has failed. |
690 | 61b5e342 | Michael Hanselmann | - ``gnt-* list`` commands now accept a new ``-o +field`` way of |
691 | 61b5e342 | Michael Hanselmann | specifying output fields, that just adds the chosen fields to the |
692 | 61b5e342 | Michael Hanselmann | default ones. |
693 | 61b5e342 | Michael Hanselmann | - ``gnt-backup`` now has a new ``remove`` command to delete an existing |
694 | 61b5e342 | Michael Hanselmann | export from the filesystem. |
695 | 61b5e342 | Michael Hanselmann | - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path |
696 | 61b5e342 | Michael Hanselmann | have been added. Using them you can enable/disable acpi and pae |
697 | 61b5e342 | Michael Hanselmann | support, and specify a path for a cd image to be exported to the |
698 | 61b5e342 | Michael Hanselmann | instance. These parameters as the name suggest only work on HVM |
699 | 61b5e342 | Michael Hanselmann | clusters. |
700 | 61b5e342 | Michael Hanselmann | - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and |
701 | 61b5e342 | Michael Hanselmann | PAE support will be set to the previously hardcoded values, but the |
702 | 61b5e342 | Michael Hanselmann | (previously hardcoded) path to the CDROM ISO image will be unset and |
703 | 61b5e342 | Michael Hanselmann | if required, needs to be set manually with ``gnt-instance modify`` |
704 | 61b5e342 | Michael Hanselmann | after the upgrade. |
705 | 61b5e342 | Michael Hanselmann | - The address to which an instance's VNC console is bound is now |
706 | 61b5e342 | Michael Hanselmann | selectable per-instance, rather than being cluster wide. Of course |
707 | 61b5e342 | Michael Hanselmann | this only applies to instances controlled via VNC, so currently just |
708 | 61b5e342 | Michael Hanselmann | applies to HVM clusters. |

718 | 61b5e342 | Michael Hanselmann | one combined status field (see the manpage for the exact values this |
719 | 61b5e342 | Michael Hanselmann | field will have) |
720 | 61b5e342 | Michael Hanselmann | - some more fixes for the mac export to hooks change |
721 | 61b5e342 | Michael Hanselmann | - make Ganeti not break with DRBD 8.2.x (which changed the version |
722 | 61b5e342 | Michael Hanselmann | format in ``/proc/drbd``) (issue 24) |
723 | 61b5e342 | Michael Hanselmann | - add an upgrade tool from "remote_raid1" disk template to "drbd" disk |
