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