Version 2.0.2 |
---|---|
2 |
- Added experimental support for stripped logical volumes; this should |
3 |
enhance performance but comes with a higher complexity in the block |
4 |
device handling; stripping is only enabled when passing |
5 |
--with-lvm-stripecount=N to configure, but codepaths are affected |
6 |
even in the non-stripped mode |
7 |
- Improved resiliency against transient failures at the end of DRBD |
8 |
resyncs, and in general of DRBD resync checks |
9 |
- Fixed a couple of issues with exports and snapshot errors |
10 |
- Fixed a couple of issues in instance listing |
11 |
- Added display of the disk size in “gnt-instance info” |
12 |
- Fixed checking for valid OSes in instance creation |
13 |
- Fixed handling of the ‘vcpus’ parameter in instance listing and in |
14 |
general of invalid parameters |
15 |
- Fixed http server library, and thus RAPI, to handle invalid |
16 |
username/password combinations correctly; this means that now they |
17 |
report unauthorized for queries too, not only for modifications, |
18 |
allowing earlier detect of configuration problems |
19 |
- Added a new ‘role’ node list field, equivalent to the master/master |
20 |
candidate/drained/offline flags combinations |
21 |
- Fixed cluster modify and changes of candidate pool size |
22 |
- Fixed cluster verify error messages for wrong files on regular nodes |
23 |
- Fixed a couple of issues with node demotion from master candidate |
24 |
role |
25 |
- Fixed node readd issues |
26 |
- Added non-interactive mode for “ganeti-masterd --no-voting” startup |
27 |
- Added a new ‘--no-voting’ option for masterfailover to fix failover |
28 |
on two-nodes clusters when the former master node is unreachable |
29 |
- Added instance reinstall over RAPI |
30 |
|
31 |
Version 2.0.1 |
32 |
- added -H/-B startup parameters to gnt-instance, which will allow |
33 |
re-adding the start in single-user option (regression from 1.2) |
34 |
- the watcher writes the instance status to a file, to allow |
35 |
monitoring to report the instance status (from the master) based on |
36 |
cached results of the watcher's queries; while this can get stale if |
37 |
the watcher is being locked due to other work on the cluster, this |
38 |
is still an improvement |
39 |
- the watcher now also restarts the node daemon and the rapi daemon if |
40 |
they died |
41 |
- fixed the watcher to handle full and drained queue cases |
42 |
- hooks export more instance data in the environment, which helps if |
43 |
hook scripts need to take action based on the instance's properties |
44 |
(no longer need to query back into ganeti) |
45 |
- instance failovers when the instance is stopped do not check for |
46 |
free RAM, so that failing over a stopped instance is possible in low |
47 |
memory situations |
48 |
- rapi uses queries for tags instead of jobs (for less job traffic), |
49 |
and for cluster tags it won't talk to masterd at all but read them |
50 |
from ssconf |
51 |
- a couple of error handling fixes in RAPI |
52 |
- drbd handling: improved the error handling of inconsistent disks |
53 |
after resync to reduce the frequency of "there are some degraded |
54 |
disks for this instance" message |
55 |
- fixed a bug in live migration when DRBD doesn't want to reconnect |
56 |
(the error handling path called a wrong function name) |
57 |
|
58 |
Version 2.0.0 final |
59 |
- no changes from rc5 |
60 |
|
61 |
Version 2.0 release candidate 5 |
62 |
- fix a couple of bugs (validation, argument checks) |
63 |
- fix gnt-cluster getmaster on non-master nodes (regression) |
64 |
- some small improvements to RAPI and IAllocator |
65 |
- make watcher automatically start the master daemon if down |
66 |
|
67 |
Version 2.0 release candidate 4 |
68 |
- change the OS list to not require locks; this helps with big |
69 |
clusters |
70 |
- fix gnt-cluster verify and gnt-cluster verify-disks when the volume |
71 |
group is broken |
72 |
- “gnt-instance info”, without any arguments, doesn't run for all |
73 |
instances anymore; either pass ‘--all’ or pass the desired |
74 |
instances; this helps against mistakes on big clusters where listing |
75 |
the information for all instances takes a long time |
76 |
- miscellaneous doc and man pages fixes |
77 |
|
78 |
Version 2.0 release candidate 3 |
79 |
- Change the internal locking model of some gnt-node commands, in |
80 |
order to reduce contention (and blocking of master daemon) when |
81 |
batching many creation/reinstall jobs |
82 |
- Fixes to Xen soft reboot |
83 |
- No longer build documentation at 'make' time, instead distribute it |
84 |
in the archive, in order to reduce the need for the whole |
85 |
docbook/rst toolchains |
86 |
|
87 |
Version 2.0 release candidate 2 |
88 |
- Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to |
89 |
2.0 |
90 |
- Fix watcher startup sequence, improves the behaviour of busy |
91 |
clusters |
92 |
- Some other fixes in cluster verify, replace-disks, gnt-instance add, |
93 |
gnt-cluster queue, KVM VNC bind address and other places |
94 |
- Some documentation fixes and updates |
95 |
|
96 |
Version 2.0 release candidate 1 |
97 |
- More documentation updates, now all docs should be more-or-less |
98 |
up-to-date |
99 |
- A couple of small fixes (mixed hypervisor clusters, offline nodes, |
100 |
etc.) |
101 |
- Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen |
102 |
PVM and KVM) |
103 |
- Fix an issue related to $libdir/run/ganeti and cluster creation |
104 |
|
105 |
Version 2.0 beta 2 |
106 |
- Xen PVM and KVM have switched the default value for the instance |
107 |
root disk to the first partition on the first drive, instead of the |
108 |
whole drive; this means that the OS installation scripts must be |
109 |
changed accordingly |
110 |
- Man pages have been updated |
111 |
- RAPI has been switched by default to HTTPS, and the exported |
112 |
functions should all work correctly |
113 |
- RAPI v1 has been removed |
114 |
- Many improvements to the KVM hypervisor |
115 |
- Block device errors are now better reported |
116 |
- Many other bugfixes and small improvements |
117 |
|
118 |
Version 2.0 beta 1 |
119 |
- Version 2 is a general rewrite of the code and therefore the |
120 |
differences are too many to list, see the design document for 2.0 in |
121 |
the doc/ subdirectory for more details |
122 |
- In this beta version there is not yet a migration path from 1.2 |
123 |
(there will be one in the final 2.0 release) |
124 |
- A few significant changes are: |
125 |
- all commands are executed by a daemon (ganeti-masterd) and the |
126 |
various gnt-* commands are just front-ends to it |
127 |
- all the commands are entered into, and executed from a job queue, |
128 |
see gnt-job(8) |
129 |
- the RAPI daemon supports read-write operations, secured by basic |
130 |
HTTP authentication on top of HTTPS |
131 |
- DRBD version 0.7 support has been removed, DRBD 8 is the only |
132 |
supported version (when migrating from Ganeti 1.2 to 2.0, you need |
133 |
to migrate to DRBD 8 first while still running Ganeti 1.2) |
134 |
- DRBD devices are using statically allocated minor numbers, which |
135 |
will be assigned to existing instances during the migration |
136 |
process |
137 |
- there is support for both Xen PVM and Xen HVM instances running on |
138 |
the same cluster |
139 |
- KVM virtualization is supported too |
140 |
- file-based storage has been implemented, which means that it is |
141 |
possible to run the cluster without LVM and DRBD storage, for |
142 |
example using a shared filesystem exported from shared storage |
143 |
(and still have live migration) |
144 |
|
145 |
Version 1.2.7 |
146 |
- Change the default reboot type in gnt-instance reboot to "hard" |
147 |
- Reuse the old instance mac address by default on instance import, |
148 |
if the instance name is the same. |
149 |
- Handle situations in which the node info rpc returns incomplete results |
150 |
(issue 46) |
151 |
- Add checks for tcp/udp ports collisions in gnt-cluster verify |
152 |
- Improved version of batcher: |
153 |
- state file support |
154 |
- instance mac address support |
155 |
- support for HVM clusters/instances |
156 |
- Add an option to show the number of cpu sockets and nodes in gnt-node list |
157 |
- Support OSes that handle more than one version of the OS api |
158 |
(but do not change the current API in any other way) |
159 |
- Fix gnt-node migrate |
160 |
- gnt-debug man page |
161 |
- Fixes various more typos&small issues |
162 |
- Increase disk resync maximum speed to 60MB/s (from 30MB/s) |
163 |
|
164 |
Version 1.2.6 |
165 |
- new --hvm-nic-type and --hvm-disk-type flags to control the type of disk |
166 |
exported to fully virtualized instances. |
167 |
- provide access to the serial console of HVM instances |
168 |
- instance auto_balance flag, set by default. If turned off it will avoid |
169 |
warnings on cluster verify if there is not enough memory to fail over an |
170 |
instance. in the future it will prevent automatically failing it over when |
171 |
we will support that. |
172 |
- batcher tool for instance creation, see /tools/README.batcher |
173 |
- gnt-instance reinstall --select-os to interactively select a new operating |
174 |
system when reinstalling an instance. |
175 |
- when changing the memory amount on instance modify a check has been added |
176 |
that the instance will be able to start. also warnings are emitted if the |
177 |
instance will not be able to fail over, if auto_balance is true. |
178 |
- documentation fixes |
179 |
- sync fields between instance list/modify/add/import |
180 |
- fix a race condition in drbd when the sync speed was set after giving the |
181 |
device a remote peer. |
182 |
|
183 |
Version 1.2.5 |
184 |
- note: the allowed size and number of tags per object were reduced |
185 |
- fix a bug in “gnt-cluster verify” with inconsistent volume groups |
186 |
- fixed twisted 8.x compatibility |
187 |
- fixed gnt-instance replace-disks with iallocator |
188 |
- add TCP keepalives on twisted connections to detect restarted nodes |
189 |
- disk increase support, see “gnt-instance grow-disk” |
190 |
- implement bulk node/instance query for RAPI |
191 |
- add tags in node/instance listing (optional) |
192 |
- experimental migration (and live migration) support, read the man |
193 |
page for “gnt-instance migrate” |
194 |
- the ganeti-watcher logs are now timestamped, and the watcher also |
195 |
has some small improvements in handling its state file |
196 |
|
197 |
Version 1.2.4 |
198 |
- Experimental readonly, REST-based remote API implementation; automatically |
199 |
started on master node, TCP port 5080, if enabled by --enable-rapi |
200 |
parameter to configure script. |
201 |
- Instance allocator support. Add and import instance accept a --iallocator |
202 |
parameter, and call that instance allocator to decide which node to use for |
203 |
the instance. The iallocator document describes what's expected from an |
204 |
allocator script. |
205 |
- gnt-cluster verify N+1 memory redundancy checks: Unless passed the |
206 |
--no-nplus1-mem option gnt-cluster verify now checks that if a node is lost |
207 |
there is still enough memory to fail over the instances that reside on it. |
208 |
- gnt-cluster verify hooks: it is now possible to add post-hooks to |
209 |
gnt-cluster verify, to check for site-specific compliance. All the hooks |
210 |
will run, and their output, if any, will be displayed. Any failing hook |
211 |
will make the verification return an error value. |
212 |
- gnt-cluster verify now checks that its peers are reachable on the primary |
213 |
and secondary interfaces |
214 |
- gnt-node add now supports the --readd option, to readd a node that is still |
215 |
declared as part of the cluster and has failed. |
216 |
- gnt-* list commands now accept a new -o +field way of specifying output |
217 |
fields, that just adds the chosen fields to the default ones. |
218 |
- gnt-backup now has a new "remove" command to delete an existing export from |
219 |
the filesystem. |
220 |
- New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path have |
221 |
been added. Using them you can enable/disable acpi and pae support, and |
222 |
specify a path for a cd image to be exported to the instance. These |
223 |
parameters as the name suggest only work on HVM clusters. |
224 |
- When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and PAE |
225 |
support will be set to the previously hardcoded values, but the (previously |
226 |
hardcoded) path to the CDROM ISO image will be unset and if required, needs |
227 |
to be set manually with gnt-instance modify after the upgrade.. |
228 |
- The address to which an instance's VNC console is bound is now selectable |
229 |
per-instance, rather than being cluster wide. Of course this only applies |
230 |
to instances controlled via VNC, so currently just applies to HVM clusters. |
231 |
|
232 |
Version 1.2.3 |
233 |
- more tweaks to the disk activation code (especially helpful for DRBD) |
234 |
- change the default ‘gnt-instance list’ output format, now there is |
235 |
one combined status field (see the manpage for the exact values this |
236 |
field will have) |
237 |
- some more fixes for the mac export to hooks change |
238 |
- make Ganeti not break with DRBD 8.2.x (which changed the version |
239 |
format in /proc/drbd) (issue 24) |
240 |
- add an upgrade tool from ‘remote_raid1’ disk template to ‘drbd’ disk |
241 |
template, allowing migration from DRBD0.7+MD to DRBD8 |
242 |
|
243 |
Version 1.2.2 |
244 |
- fix ‘gnt-instance modify’ breakage introduced in 1.2.1 with the HVM |
245 |
support (issue 23) |
246 |
- add command aliases infrastructure and a few aliases |
247 |
- allow listing of VCPUs in the gnt-instance list and improve the man |
248 |
pages and the --help option of gnt-node/gnt-instance list |
249 |
- fix gnt-backup list with down nodes (issue 21) |
250 |
- change the tools location (move from $pkgdatadir to |
251 |
$pkglibdir/tools) |
252 |
- fix the dist archive and add a check for including svn/git files in |
253 |
the future |
254 |
- some developer-related changes: improve the burnin and the QA |
255 |
suite, add an upload script for testing during development |
256 |
|
257 |
Version 1.2.1 |
258 |
- experimental HVM support, read the install document, section |
259 |
"Initializing the cluster" |
260 |
- allow for the PVM hypervisor per-instance kernel and initrd paths |
261 |
- add a new command ‘gnt-cluster verify-disks’ which uses a new |
262 |
algorithm to improve the reconnection of the DRBD pairs if the |
263 |
device on the secondary node has gone away |
264 |
- make logical volume code auto-activate LVs at disk activation time |
265 |
- slightly improve the speed of activating disks |
266 |
- allow specification of the MAC address at instance creation time, |
267 |
and changing it later via ‘gnt-instance modify’ |
268 |
- fix handling of external commands that generate lots of output on |
269 |
stderr |
270 |
- update documentation with regard to minimum version of DRBD8 |
271 |
supported |
272 |
|
273 |
Version 1.2.0 |
274 |
- Log the ‘xm create’ output to the node daemon log on failure (to |
275 |
help diagnosing the error) |
276 |
- In debug mode, log all external commands output if failed to the |
277 |
logs |
278 |
- Change parsing of lvm commands to ignore stderr |
279 |
|
280 |
Version 1.2b3 |
281 |
- Another round of updates to the DRBD 8 code to deal with more |
282 |
failures in the replace secondary node operation |
283 |
- Some more logging of failures in disk operations (lvm, drbd) |
284 |
- A few documentation updates |
285 |
- QA updates |
286 |
|
287 |
Version 1.2b2 |
288 |
- Change configuration file format from Python's Pickle to JSON. |
289 |
Upgrading is possible using the cfgupgrade utility. |
290 |
- Add support for DRBD 8.0 (new disk template `drbd`) which allows for |
291 |
faster replace disks and is more stable (DRBD 8 has many |
292 |
improvements compared to DRBD 0.7) |
293 |
- Added command line tags support (see man pages for gnt-instance, |
294 |
gnt-node, gnt-cluster) |
295 |
- Added instance rename support |
296 |
- Added multi-instance startup/shutdown |
297 |
- Added cluster rename support |
298 |
- Added `gnt-node evacuate` to simplify some node operations |
299 |
- Added instance reboot operation that can speedup reboot as compared |
300 |
to stop and start |
301 |
- Soften the requirement that hostnames are in FQDN format |
302 |
- The ganeti-watcher now activates drbd pairs after secondary node |
303 |
reboots |
304 |
- Removed dependency on debian's patched fping that uses the |
305 |
non-standard -S option |
306 |
- Now the OS definitions are searched for in multiple, configurable |
307 |
paths (easier for distros to package) |
308 |
- Some changes to the hooks infrastructure (especially the new |
309 |
post-configuration update hook) |
310 |
- Other small bugfixes |
