1 | 10f31783 | Iustin Pop | Version 2.0 beta 1 |
---|---|---|---|
2 | 10f31783 | Iustin Pop | - Version 2 is a general rewrite of the code and therefore the |
3 | 10f31783 | Iustin Pop | differences are too many to list, see the design document for 2.0 in |
4 | 10f31783 | Iustin Pop | the doc/ subdirectory for more details |
5 | 10f31783 | Iustin Pop | - In this beta version there is not yet a migration path from 1.2 |
6 | 10f31783 | Iustin Pop | (there will be one in the final 2.0 release) |
7 | 10f31783 | Iustin Pop | - A few significant changes are: |
8 | 10f31783 | Iustin Pop | - all commands are executed by a daemon (ganeti-masterd) and the |
9 | 10f31783 | Iustin Pop | various gnt-* commands are just front-ends to it |
10 | 10f31783 | Iustin Pop | - all the commands are entered into, and executed from a job queue, |
11 | 10f31783 | Iustin Pop | see gnt-job(8) |
12 | 10f31783 | Iustin Pop | - the RAPI daemon supports read-write operations, secured by basic |
13 | 10f31783 | Iustin Pop | HTTP authentication on top of HTTPS |
14 | 10f31783 | Iustin Pop | - DRBD version 0.7 support has been removed, DRBD 8 is the only |
15 | 10f31783 | Iustin Pop | supported version (when migrating from Ganeti 1.2 to 2.0, you need |
16 | 10f31783 | Iustin Pop | to migrate to DRBD 8 first while still running Ganeti 1.2) |
17 | 10f31783 | Iustin Pop | - DRBD devices are using statically allocated minor numbers, which |
18 | 10f31783 | Iustin Pop | will be assigned to existing instances during the migration |
19 | 10f31783 | Iustin Pop | process |
20 | 10f31783 | Iustin Pop | - there is support for both Xen PVM and Xen HVM instances running on |
21 | 10f31783 | Iustin Pop | the same cluster |
22 | 10f31783 | Iustin Pop | - KVM virtualization is supported too |
23 | 10f31783 | Iustin Pop | - file-based storage has been implemented, which means that it is |
24 | 10f31783 | Iustin Pop | possible to run the cluster without LVM and DRBD storage, for |
25 | 10f31783 | Iustin Pop | example using a shared filesystem exported from shared storage |
26 | 10f31783 | Iustin Pop | (and still have live migration) |
27 | 10f31783 | Iustin Pop | |
28 | 10f31783 | Iustin Pop | Version 1.2.7 |
29 | 10f31783 | Iustin Pop | - Change the default reboot type in gnt-instance reboot to "hard" |
30 | 10f31783 | Iustin Pop | - Reuse the old instance mac address by default on instance import, |
31 | 10f31783 | Iustin Pop | if the instance name is the same. |
32 | 10f31783 | Iustin Pop | - Handle situations in which the node info rpc returns incomplete results |
33 | 10f31783 | Iustin Pop | (issue 46) |
34 | 10f31783 | Iustin Pop | - Add checks for tcp/udp ports collisions in gnt-cluster verify |
35 | 10f31783 | Iustin Pop | - Improved version of batcher: |
36 | 10f31783 | Iustin Pop | - state file support |
37 | 10f31783 | Iustin Pop | - instance mac address support |
38 | 10f31783 | Iustin Pop | - support for HVM clusters/instances |
39 | 10f31783 | Iustin Pop | - Add an option to show the number of cpu sockets and nodes in gnt-node list |
40 | 10f31783 | Iustin Pop | - Support OSes that handle more than one version of the OS api |
41 | 10f31783 | Iustin Pop | (but do not change the current API in any other way) |
42 | 10f31783 | Iustin Pop | - Fix gnt-node migrate |
43 | 10f31783 | Iustin Pop | - gnt-debug man page |
44 | 10f31783 | Iustin Pop | - Fixes various more typos&small issues |
45 | 10f31783 | Iustin Pop | - Increase disk resync maximum speed to 60MB/s (from 30MB/s) |
46 | 10f31783 | Iustin Pop | |
47 | 10f31783 | Iustin Pop | Version 1.2.6 |
48 | 10f31783 | Iustin Pop | - new --hvm-nic-type and --hvm-disk-type flags to control the type of disk |
49 | 10f31783 | Iustin Pop | exported to fully virtualized instances. |
50 | 10f31783 | Iustin Pop | - provide access to the serial console of HVM instances |
51 | 10f31783 | Iustin Pop | - instance auto_balance flag, set by default. If turned off it will avoid |
52 | 10f31783 | Iustin Pop | warnings on cluster verify if there is not enough memory to fail over an |
53 | 10f31783 | Iustin Pop | instance. in the future it will prevent automatically failing it over when |
54 | 10f31783 | Iustin Pop | we will support that. |
55 | 10f31783 | Iustin Pop | - batcher tool for instance creation, see /tools/README.batcher |
56 | 10f31783 | Iustin Pop | - gnt-instance reinstall --select-os to interactively select a new operating |
57 | 10f31783 | Iustin Pop | system when reinstalling an instance. |
58 | 10f31783 | Iustin Pop | - when changing the memory amount on instance modify a check has been added |
59 | 10f31783 | Iustin Pop | that the instance will be able to start. also warnings are emitted if the |
60 | 10f31783 | Iustin Pop | instance will not be able to fail over, if auto_balance is true. |
61 | 10f31783 | Iustin Pop | - documentation fixes |
62 | 10f31783 | Iustin Pop | - sync fields between instance list/modify/add/import |
63 | 10f31783 | Iustin Pop | - fix a race condition in drbd when the sync speed was set after giving the |
64 | 10f31783 | Iustin Pop | device a remote peer. |
65 | 10f31783 | Iustin Pop | |
66 | 10f31783 | Iustin Pop | Version 1.2.5 |
67 | 10f31783 | Iustin Pop | - note: the allowed size and number of tags per object were reduced |
68 | 10f31783 | Iustin Pop | - fix a bug in “gnt-cluster verify” with inconsistent volume groups |
69 | 10f31783 | Iustin Pop | - fixed twisted 8.x compatibility |
70 | 10f31783 | Iustin Pop | - fixed gnt-instance replace-disks with iallocator |
71 | 10f31783 | Iustin Pop | - add TCP keepalives on twisted connections to detect restarted nodes |
72 | 10f31783 | Iustin Pop | - disk increase support, see “gnt-instance grow-disk” |
73 | 10f31783 | Iustin Pop | - implement bulk node/instance query for RAPI |
74 | 10f31783 | Iustin Pop | - add tags in node/instance listing (optional) |
75 | 10f31783 | Iustin Pop | - experimental migration (and live migration) support, read the man |
76 | 10f31783 | Iustin Pop | page for “gnt-instance migrate” |
77 | 10f31783 | Iustin Pop | - the ganeti-watcher logs are now timestamped, and the watcher also |
78 | 10f31783 | Iustin Pop | has some small improvements in handling its state file |
79 | 10f31783 | Iustin Pop | |
80 | 10f31783 | Iustin Pop | Version 1.2.4 |
81 | 10f31783 | Iustin Pop | - Experimental readonly, REST-based remote API implementation; automatically |
82 | 10f31783 | Iustin Pop | started on master node, TCP port 5080, if enabled by --enable-rapi |
83 | 10f31783 | Iustin Pop | parameter to configure script. |
84 | 10f31783 | Iustin Pop | - Instance allocator support. Add and import instance accept a --iallocator |
85 | 10f31783 | Iustin Pop | parameter, and call that instance allocator to decide which node to use for |
86 | 10f31783 | Iustin Pop | the instance. The iallocator document describes what's expected from an |
87 | 10f31783 | Iustin Pop | allocator script. |
88 | 10f31783 | Iustin Pop | - gnt-cluster verify N+1 memory redundancy checks: Unless passed the |
89 | 10f31783 | Iustin Pop | --no-nplus1-mem option gnt-cluster verify now checks that if a node is lost |
90 | 10f31783 | Iustin Pop | there is still enough memory to fail over the instances that reside on it. |
91 | 10f31783 | Iustin Pop | - gnt-cluster verify hooks: it is now possible to add post-hooks to |
92 | 10f31783 | Iustin Pop | gnt-cluster verify, to check for site-specific compliance. All the hooks |
93 | 10f31783 | Iustin Pop | will run, and their output, if any, will be displayed. Any failing hook |
94 | 10f31783 | Iustin Pop | will make the verification return an error value. |
95 | 10f31783 | Iustin Pop | - gnt-cluster verify now checks that its peers are reachable on the primary |
96 | 10f31783 | Iustin Pop | and secondary interfaces |
97 | 10f31783 | Iustin Pop | - gnt-node add now supports the --readd option, to readd a node that is still |
98 | 10f31783 | Iustin Pop | declared as part of the cluster and has failed. |
99 | 10f31783 | Iustin Pop | - gnt-* list commands now accept a new -o +field way of specifying output |
100 | 10f31783 | Iustin Pop | fields, that just adds the chosen fields to the default ones. |
101 | 10f31783 | Iustin Pop | - gnt-backup now has a new "remove" command to delete an existing export from |
102 | 10f31783 | Iustin Pop | the filesystem. |
103 | 10f31783 | Iustin Pop | - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path have |
104 | 10f31783 | Iustin Pop | been added. Using them you can enable/disable acpi and pae support, and |
105 | 10f31783 | Iustin Pop | specify a path for a cd image to be exported to the instance. These |
106 | 10f31783 | Iustin Pop | parameters as the name suggest only work on HVM clusters. |
107 | 10f31783 | Iustin Pop | - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and PAE |
108 | 10f31783 | Iustin Pop | support will be set to the previously hardcoded values, but the (previously |
109 | 10f31783 | Iustin Pop | hardcoded) path to the CDROM ISO image will be unset and if required, needs |
110 | 10f31783 | Iustin Pop | to be set manually with gnt-instance modify after the upgrade.. |
111 | 10f31783 | Iustin Pop | - The address to which an instance's VNC console is bound is now selectable |
112 | 10f31783 | Iustin Pop | per-instance, rather than being cluster wide. Of course this only applies |
113 | 10f31783 | Iustin Pop | to instances controlled via VNC, so currently just applies to HVM clusters. |
114 | 10f31783 | Iustin Pop | |
115 | bae27f68 | Iustin Pop | Version 1.2.3 |
116 | bae27f68 | Iustin Pop | - more tweaks to the disk activation code (especially helpful for DRBD) |
117 | bae27f68 | Iustin Pop | - change the default ‘gnt-instance list’ output format, now there is |
118 | bae27f68 | Iustin Pop | one combined status field (see the manpage for the exact values this |
119 | bae27f68 | Iustin Pop | field will have) |
120 | bae27f68 | Iustin Pop | - some more fixes for the mac export to hooks change |
121 | bae27f68 | Iustin Pop | - make Ganeti not break with DRBD 8.2.x (which changed the version |
122 | bae27f68 | Iustin Pop | format in /proc/drbd) (issue 24) |
123 | bae27f68 | Iustin Pop | - add an upgrade tool from ‘remote_raid1’ disk template to ‘drbd’ disk |
124 | bae27f68 | Iustin Pop | template, allowing migration from DRBD0.7+MD to DRBD8 |
125 | bae27f68 | Iustin Pop | |
126 | e709baee | Iustin Pop | Version 1.2.2 |
127 | e709baee | Iustin Pop | - fix ‘gnt-instance modify’ breakage introduced in 1.2.1 with the HVM |

129 | e709baee | Iustin Pop | - add command aliases infrastructure and a few aliases |
130 | e709baee | Iustin Pop | - allow listing of VCPUs in the gnt-instance list and improve the man |
131 | e709baee | Iustin Pop | pages and the --help option of gnt-node/gnt-instance list |
132 | e709baee | Iustin Pop | - fix gnt-backup list with down nodes (issue 21) |
133 | e709baee | Iustin Pop | - change the tools location (move from $pkgdatadir to |
134 | e709baee | Iustin Pop | $pkglibdir/tools) |
135 | e709baee | Iustin Pop | - fix the dist archive and add a check for including svn/git files in |
136 | e709baee | Iustin Pop | the future |
137 | e709baee | Iustin Pop | - some developer-related changes: improve the burnin and the QA |

143 | 31b9055c | Iustin Pop | - allow for the PVM hypervisor per-instance kernel and initrd paths |
144 | 31b9055c | Iustin Pop | - add a new command ‘gnt-cluster verify-disks’ which uses a new |
145 | 31b9055c | Iustin Pop | algorithm to improve the reconnection of the DRBD pairs if the |
146 | 31b9055c | Iustin Pop | device on the secondary node has gone away |

174 | 6c4811dc | Iustin Pop | faster replace disks and is more stable (DRBD 8 has many |
175 | 6c4811dc | Iustin Pop | improvements compared to DRBD 0.7) |
176 | 6c4811dc | Iustin Pop | - Added command line tags support (see man pages for gnt-instance, |
