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