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