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