2 - note: the allowed size and number of tags per object were reduced
3 - fix a bug in “gnt-cluster verify” with inconsistent volume groups
4 - fixed twisted 8.x compatibility
5 - fixed gnt-instance replace-disks with iallocator
6 - add TCP keepalives on twisted connections to detect restarted nodes
7 - disk increase support, see “gnt-instance grow-disk”
8 - implement bulk node/instance query for RAPI
9 - add tags in node/instance listing (optional)
10 - experimental migration (and live migration) support, read the man
11 page for “gnt-instance migrate”
12 - the ganeti-watcher logs are now timestamped, and the watcher also
13 has some small improvements in handling its state file
16 - Experimental readonly, REST-based remote API implementation; automatically
17 started on master node, TCP port 5080, if enabled by --enable-rapi
18 parameter to configure script.
19 - Instance allocator support. Add and import instance accept a --iallocator
20 parameter, and call that instance allocator to decide which node to use for
21 the instance. The iallocator document describes what's expected from an
23 - gnt-cluster verify N+1 memory redundancy checks: Unless passed the
24 --no-nplus1-mem option gnt-cluster verify now checks that if a node is lost
25 there is still enough memory to fail over the instances that reside on it.
26 - gnt-cluster verify hooks: it is now possible to add post-hooks to
27 gnt-cluster verify, to check for site-specific compliance. All the hooks
28 will run, and their output, if any, will be displayed. Any failing hook
29 will make the verification return an error value.
30 - gnt-cluster verify now checks that its peers are reachable on the primary
31 and secondary interfaces
32 - gnt-node add now supports the --readd option, to readd a node that is still
33 declared as part of the cluster and has failed.
34 - gnt-* list commands now accept a new -o +field way of specifying output
35 fields, that just adds the chosen fields to the default ones.
36 - gnt-backup now has a new "remove" command to delete an existing export from
38 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path have
39 been added. Using them you can enable/disable acpi and pae support, and
40 specify a path for a cd image to be exported to the instance. These
41 parameters as the name suggest only work on HVM clusters.
42 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and PAE
43 support will be set to the previously hardcoded values, but the (previously
44 hardcoded) path to the CDROM ISO image will be unset and if required, needs
45 to be set manually with gnt-instance modify after the upgrade..
46 - The address to which an instance's VNC console is bound is now selectable
47 per-instance, rather than being cluster wide. Of course this only applies
48 to instances controlled via VNC, so currently just applies to HVM clusters.
51 - more tweaks to the disk activation code (especially helpful for DRBD)
52 - change the default ‘gnt-instance list’ output format, now there is
53 one combined status field (see the manpage for the exact values this
55 - some more fixes for the mac export to hooks change
56 - make Ganeti not break with DRBD 8.2.x (which changed the version
57 format in /proc/drbd) (issue 24)
58 - add an upgrade tool from ‘remote_raid1’ disk template to ‘drbd’ disk
59 template, allowing migration from DRBD0.7+MD to DRBD8
62 - fix ‘gnt-instance modify’ breakage introduced in 1.2.1 with the HVM
64 - add command aliases infrastructure and a few aliases
65 - allow listing of VCPUs in the gnt-instance list and improve the man
66 pages and the --help option of gnt-node/gnt-instance list
67 - fix gnt-backup list with down nodes (issue 21)
68 - change the tools location (move from $pkgdatadir to
70 - fix the dist archive and add a check for including svn/git files in
72 - some developer-related changes: improve the burnin and the QA
73 suite, add an upload script for testing during development
76 - experimental HVM support, read the install document, section
77 "Initializing the cluster"
78 - allow for the PVM hypervisor per-instance kernel and initrd paths
79 - add a new command ‘gnt-cluster verify-disks’ which uses a new
80 algorithm to improve the reconnection of the DRBD pairs if the
81 device on the secondary node has gone away
82 - make logical volume code auto-activate LVs at disk activation time
83 - slightly improve the speed of activating disks
84 - allow specification of the MAC address at instance creation time,
85 and changing it later via ‘gnt-instance modify’
86 - fix handling of external commands that generate lots of output on
88 - update documentation with regard to minimum version of DRBD8
92 - Log the ‘xm create’ output to the node daemon log on failure (to
93 help diagnosing the error)
94 - In debug mode, log all external commands output if failed to the
96 - Change parsing of lvm commands to ignore stderr
99 - Another round of updates to the DRBD 8 code to deal with more
100 failures in the replace secondary node operation
101 - Some more logging of failures in disk operations (lvm, drbd)
102 - A few documentation updates
106 - Change configuration file format from Python's Pickle to JSON.
107 Upgrading is possible using the cfgupgrade utility.
108 - Add support for DRBD 8.0 (new disk template `drbd`) which allows for
109 faster replace disks and is more stable (DRBD 8 has many
110 improvements compared to DRBD 0.7)
111 - Added command line tags support (see man pages for gnt-instance,
112 gnt-node, gnt-cluster)
113 - Added instance rename support
114 - Added multi-instance startup/shutdown
115 - Added cluster rename support
116 - Added `gnt-node evacuate` to simplify some node operations
117 - Added instance reboot operation that can speedup reboot as compared
119 - Soften the requirement that hostnames are in FQDN format
120 - The ganeti-watcher now activates drbd pairs after secondary node
122 - Removed dependency on debian's patched fping that uses the
123 non-standard -S option
124 - Now the OS definitions are searched for in multiple, configurable
125 paths (easier for distros to package)
126 - Some changes to the hooks infrastructure (especially the new
127 post-configuration update hook)
128 - Other small bugfixes
