1 Version 2.0 release candidate 5
2 - fix a couple of bugs (validation, argument checks)
3 - fix gnt-cluster getmaster on non-master nodes (regression)
4 - some small improvements to RAPI and IAllocator
5 - make watcher automatically start the master daemon if down
7 Version 2.0 release candidate 4
8 - change the OS list to not require locks; this helps with big
10 - fix gnt-cluster verify and gnt-cluster verify-disks when the volume
12 - “gnt-instance info”, without any arguments, doesn't run for all
13 instances anymore; either pass ‘--all’ or pass the desired
14 instances; this helps against mistakes on big clusters where listing
15 the information for all instances takes a long time
16 - miscellaneous doc and man pages fixes
18 Version 2.0 release candidate 3
19 - Change the internal locking model of some gnt-node commands, in
20 order to reduce contention (and blocking of master daemon) when
21 batching many creation/reinstall jobs
22 - Fixes to Xen soft reboot
23 - No longer build documentation at 'make' time, instead distribute it
24 in the archive, in order to reduce the need for the whole
25 docbook/rst toolchains
27 Version 2.0 release candidate 2
28 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to
30 - Fix watcher startup sequence, improves the behaviour of busy
32 - Some other fixes in cluster verify, replace-disks, gnt-instance add,
33 gnt-cluster queue, KVM VNC bind address and other places
34 - Some documentation fixes and updates
36 Version 2.0 release candidate 1
37 - More documentation updates, now all docs should be more-or-less
39 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
41 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen
43 - Fix an issue related to $libdir/run/ganeti and cluster creation
46 - Xen PVM and KVM have switched the default value for the instance
47 root disk to the first partition on the first drive, instead of the
48 whole drive; this means that the OS installation scripts must be
50 - Man pages have been updated
51 - RAPI has been switched by default to HTTPS, and the exported
52 functions should all work correctly
53 - RAPI v1 has been removed
54 - Many improvements to the KVM hypervisor
55 - Block device errors are now better reported
56 - Many other bugfixes and small improvements
59 - Version 2 is a general rewrite of the code and therefore the
60 differences are too many to list, see the design document for 2.0 in
61 the doc/ subdirectory for more details
62 - In this beta version there is not yet a migration path from 1.2
63 (there will be one in the final 2.0 release)
64 - A few significant changes are:
65 - all commands are executed by a daemon (ganeti-masterd) and the
66 various gnt-* commands are just front-ends to it
67 - all the commands are entered into, and executed from a job queue,
69 - the RAPI daemon supports read-write operations, secured by basic
70 HTTP authentication on top of HTTPS
71 - DRBD version 0.7 support has been removed, DRBD 8 is the only
72 supported version (when migrating from Ganeti 1.2 to 2.0, you need
73 to migrate to DRBD 8 first while still running Ganeti 1.2)
74 - DRBD devices are using statically allocated minor numbers, which
75 will be assigned to existing instances during the migration
77 - there is support for both Xen PVM and Xen HVM instances running on
79 - KVM virtualization is supported too
80 - file-based storage has been implemented, which means that it is
81 possible to run the cluster without LVM and DRBD storage, for
82 example using a shared filesystem exported from shared storage
83 (and still have live migration)
86 - Change the default reboot type in gnt-instance reboot to "hard"
87 - Reuse the old instance mac address by default on instance import,
88 if the instance name is the same.
89 - Handle situations in which the node info rpc returns incomplete results
91 - Add checks for tcp/udp ports collisions in gnt-cluster verify
92 - Improved version of batcher:
94 - instance mac address support
95 - support for HVM clusters/instances
96 - Add an option to show the number of cpu sockets and nodes in gnt-node list
97 - Support OSes that handle more than one version of the OS api
98 (but do not change the current API in any other way)
99 - Fix gnt-node migrate
101 - Fixes various more typos&small issues
102 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
105 - new --hvm-nic-type and --hvm-disk-type flags to control the type of disk
106 exported to fully virtualized instances.
107 - provide access to the serial console of HVM instances
108 - instance auto_balance flag, set by default. If turned off it will avoid
109 warnings on cluster verify if there is not enough memory to fail over an
110 instance. in the future it will prevent automatically failing it over when
111 we will support that.
112 - batcher tool for instance creation, see /tools/README.batcher
113 - gnt-instance reinstall --select-os to interactively select a new operating
114 system when reinstalling an instance.
115 - when changing the memory amount on instance modify a check has been added
116 that the instance will be able to start. also warnings are emitted if the
117 instance will not be able to fail over, if auto_balance is true.
118 - documentation fixes
119 - sync fields between instance list/modify/add/import
120 - fix a race condition in drbd when the sync speed was set after giving the
121 device a remote peer.
124 - note: the allowed size and number of tags per object were reduced
125 - fix a bug in “gnt-cluster verify” with inconsistent volume groups
126 - fixed twisted 8.x compatibility
127 - fixed gnt-instance replace-disks with iallocator
128 - add TCP keepalives on twisted connections to detect restarted nodes
129 - disk increase support, see “gnt-instance grow-disk”
130 - implement bulk node/instance query for RAPI
131 - add tags in node/instance listing (optional)
132 - experimental migration (and live migration) support, read the man
133 page for “gnt-instance migrate”
134 - the ganeti-watcher logs are now timestamped, and the watcher also
135 has some small improvements in handling its state file
138 - Experimental readonly, REST-based remote API implementation; automatically
139 started on master node, TCP port 5080, if enabled by --enable-rapi
140 parameter to configure script.
141 - Instance allocator support. Add and import instance accept a --iallocator
142 parameter, and call that instance allocator to decide which node to use for
143 the instance. The iallocator document describes what's expected from an
145 - gnt-cluster verify N+1 memory redundancy checks: Unless passed the
146 --no-nplus1-mem option gnt-cluster verify now checks that if a node is lost
147 there is still enough memory to fail over the instances that reside on it.
148 - gnt-cluster verify hooks: it is now possible to add post-hooks to
149 gnt-cluster verify, to check for site-specific compliance. All the hooks
150 will run, and their output, if any, will be displayed. Any failing hook
151 will make the verification return an error value.
152 - gnt-cluster verify now checks that its peers are reachable on the primary
153 and secondary interfaces
154 - gnt-node add now supports the --readd option, to readd a node that is still
155 declared as part of the cluster and has failed.
156 - gnt-* list commands now accept a new -o +field way of specifying output
157 fields, that just adds the chosen fields to the default ones.
158 - gnt-backup now has a new "remove" command to delete an existing export from
160 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path have
161 been added. Using them you can enable/disable acpi and pae support, and
162 specify a path for a cd image to be exported to the instance. These
163 parameters as the name suggest only work on HVM clusters.
164 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and PAE
165 support will be set to the previously hardcoded values, but the (previously
166 hardcoded) path to the CDROM ISO image will be unset and if required, needs
167 to be set manually with gnt-instance modify after the upgrade..
168 - The address to which an instance's VNC console is bound is now selectable
169 per-instance, rather than being cluster wide. Of course this only applies
170 to instances controlled via VNC, so currently just applies to HVM clusters.
173 - more tweaks to the disk activation code (especially helpful for DRBD)
174 - change the default ‘gnt-instance list’ output format, now there is
175 one combined status field (see the manpage for the exact values this
177 - some more fixes for the mac export to hooks change
178 - make Ganeti not break with DRBD 8.2.x (which changed the version
179 format in /proc/drbd) (issue 24)
180 - add an upgrade tool from ‘remote_raid1’ disk template to ‘drbd’ disk
181 template, allowing migration from DRBD0.7+MD to DRBD8
184 - fix ‘gnt-instance modify’ breakage introduced in 1.2.1 with the HVM
186 - add command aliases infrastructure and a few aliases
187 - allow listing of VCPUs in the gnt-instance list and improve the man
188 pages and the --help option of gnt-node/gnt-instance list
189 - fix gnt-backup list with down nodes (issue 21)
190 - change the tools location (move from $pkgdatadir to
192 - fix the dist archive and add a check for including svn/git files in
194 - some developer-related changes: improve the burnin and the QA
195 suite, add an upload script for testing during development
198 - experimental HVM support, read the install document, section
199 "Initializing the cluster"
200 - allow for the PVM hypervisor per-instance kernel and initrd paths
201 - add a new command ‘gnt-cluster verify-disks’ which uses a new
202 algorithm to improve the reconnection of the DRBD pairs if the
203 device on the secondary node has gone away
204 - make logical volume code auto-activate LVs at disk activation time
205 - slightly improve the speed of activating disks
206 - allow specification of the MAC address at instance creation time,
207 and changing it later via ‘gnt-instance modify’
208 - fix handling of external commands that generate lots of output on
210 - update documentation with regard to minimum version of DRBD8
214 - Log the ‘xm create’ output to the node daemon log on failure (to
215 help diagnosing the error)
216 - In debug mode, log all external commands output if failed to the
218 - Change parsing of lvm commands to ignore stderr
221 - Another round of updates to the DRBD 8 code to deal with more
222 failures in the replace secondary node operation
223 - Some more logging of failures in disk operations (lvm, drbd)
224 - A few documentation updates
228 - Change configuration file format from Python's Pickle to JSON.
229 Upgrading is possible using the cfgupgrade utility.
230 - Add support for DRBD 8.0 (new disk template `drbd`) which allows for
231 faster replace disks and is more stable (DRBD 8 has many
232 improvements compared to DRBD 0.7)
233 - Added command line tags support (see man pages for gnt-instance,
234 gnt-node, gnt-cluster)
235 - Added instance rename support
236 - Added multi-instance startup/shutdown
237 - Added cluster rename support
238 - Added `gnt-node evacuate` to simplify some node operations
239 - Added instance reboot operation that can speedup reboot as compared
241 - Soften the requirement that hostnames are in FQDN format
242 - The ganeti-watcher now activates drbd pairs after secondary node
244 - Removed dependency on debian's patched fping that uses the
245 non-standard -S option
246 - Now the OS definitions are searched for in multiple, configurable
247 paths (easier for distros to package)
248 - Some changes to the hooks infrastructure (especially the new
249 post-configuration update hook)
250 - Other small bugfixes
