1 | 2fe61f87 | Iustin Pop | Version 0.1.6 (Wed, 19 Aug 2009): |
---|---|---|---|
2 | 2fe61f87 | Iustin Pop | - Added support for Luxi (the native Ganeti protocol) |
3 | 2fe61f87 | Iustin Pop | - Added support for simulated clusters (for hspace only) |
4 | 2fe61f87 | Iustin Pop | - Added timeouts for the RAPI backend |
5 | 2fe61f87 | Iustin Pop | - Fixed a few inconsistencies in the command line handling |
6 | 2fe61f87 | Iustin Pop | - Fixed handling of errors while loading data |
7 | 2fe61f87 | Iustin Pop | - The 'network' is a new dependency due to the Luxi addition |
8 | 2fe61f87 | Iustin Pop | |
9 | d8de9112 | Iustin Pop | Version 0.1.5 (Thu, 09 Jul 2009): |
10 | d8de9112 | Iustin Pop | - Removed obsolete hn1 program; this allowed removal of a lot of |
11 | d8de9112 | Iustin Pop | supporting code |
12 | d8de9112 | Iustin Pop | - Lots of changes in hspace: the output now is a shell fragment in |
13 | d8de9112 | Iustin Pop | order for script to source it or parse it easier; added failure |
14 | d8de9112 | Iustin Pop | reasons; optimised to use less memory for large clusters |
15 | d8de9112 | Iustin Pop | - Optimized the scoring algorithm (used by all tools) so that now |
16 | d8de9112 | Iustin Pop | computations should be faster |
17 | d8de9112 | Iustin Pop | |
18 | c254061a | Iustin Pop | Version 0.1.4 (Tue, 16 Jun 2009): |
19 | c254061a | Iustin Pop | - Added CPU count/ratio of virtual-to-physical CPUs to the cluster |
20 | c254061a | Iustin Pop | scoring methods; this means that now the balancer, the iallocator |
21 | c254061a | Iustin Pop | plugin and so on will try to keep the VCPU-to-PCPU ratio equal |
22 | c254061a | Iustin Pop | across the cluster |
23 | c254061a | Iustin Pop | - Fixed some hscan bugs |
24 | c254061a | Iustin Pop | - Fixed the way iallocator reads the total disk size (was broken and |
25 | c254061a | Iustin Pop | it was always falling back to summing the disk sizes) |
26 | c254061a | Iustin Pop | - Internals: fixed most compile-time warnings |
27 | c254061a | Iustin Pop | |
28 | 61d67afe | Iustin Pop | Version 0.1.3 (Fri, 05 Jun 2009): |
29 | 61d67afe | Iustin Pop | - Fix a bug in the ReplacePrimary instance moves, affecting most of |
30 | 61d67afe | Iustin Pop | the tools |
31 | 61d67afe | Iustin Pop | |
32 | bfb03e22 | Iustin Pop | Version 0.1.2 (Tue, 02 Jun 2009): |
33 | bfb03e22 | Iustin Pop | - Add a new program, “hspace”, which computes the free space on a |
34 | bfb03e22 | Iustin Pop | cluster (based on a given instance spec) |
35 | bfb03e22 | Iustin Pop | - Improvements in API docs and partially in the user docs |
36 | bfb03e22 | Iustin Pop | - Started adding unittests |
37 | bfb03e22 | Iustin Pop | |
38 | a097adcc | Iustin Pop | Version 0.1.1 (Tue, 26 May 2009): |
39 | 2c9b2122 | Iustin Pop | - Add a new program, “hail”, which is an iallocator plugin and can |
40 | 2c9b2122 | Iustin Pop | allocate/relocate instances |
41 | 2c9b2122 | Iustin Pop | - Experimental support for non-mirrored instances (hail supports them, |
42 | 2c9b2122 | Iustin Pop | hbal should no longer abort when it finds such instances and simply |
43 | 2c9b2122 | Iustin Pop | ignore them) |
44 | 2c9b2122 | Iustin Pop | - The RAPI port and/or scheme can be overriden now, and even “file://” |
45 | 2c9b2122 | Iustin Pop | schemes can be used if the message body has been saved under the |
46 | 2c9b2122 | Iustin Pop | appropriate name |
47 | 2c9b2122 | Iustin Pop | - Lots of code reorganization, esp. rewritten loading pipeline |
48 | 2c9b2122 | Iustin Pop | - Better data checking and better error messages in case validation |
49 | 2c9b2122 | Iustin Pop | fails; tools now consider nodes with error in input data (‘?’ |
50 | 2c9b2122 | Iustin Pop | returned by ganeti) as offline |
51 | a097adcc | Iustin Pop | - Small enhancement to the makefile for simpler packaging |
52 | 2c9b2122 | Iustin Pop | |
53 | 2cf61508 | Iustin Pop | Version 0.1.0 (Tue, 19 May 2009): |
54 | 2cf61508 | Iustin Pop | - Drop compatibility with Ganeti 1.2 |
55 | 2cf61508 | Iustin Pop | - Add a new minimum score option (with a very low default), should |
56 | 2cf61508 | Iustin Pop | help with very good clusters (but is still not optimal) |
57 | 2cf61508 | Iustin Pop | - Add a --quiet option to hbal |
58 | 2cf61508 | Iustin Pop | - Add support for reading offline nodes directly from the cluster |
59 | 2cf61508 | Iustin Pop | |
60 | 48470548 | Iustin Pop | Version 0.0.8 (Tue, 21 Apr 2009): |
61 | 48470548 | Iustin Pop | - hbal: prevent mismatches in wrong node names being passed to -O, by |
62 | 2c9b2122 | Iustin Pop | aborting in this case |
63 | 2c9b2122 | Iustin Pop | - add the ability to write the commands (-C) to a script via |
64 | 2c9b2122 | Iustin Pop | (-C<file>), so that it can be later executed directly; this has also |
65 | 2c9b2122 | Iustin Pop | changed the commands to include the ncessary -f flags to skip |
66 | 2c9b2122 | Iustin Pop | confirmations |
67 | 2c9b2122 | Iustin Pop | - add checks for extra argument in hbal and hn1, so that unintended |
68 | 2c9b2122 | Iustin Pop | errors are catched |
69 | 2c9b2122 | Iustin Pop | - raise the accepted “missing” memory limit to 512MB, to cover usual |
70 | 2c9b2122 | Iustin Pop | Xen reservations |
71 | 48470548 | Iustin Pop | |
72 | c5bd8d89 | Iustin Pop | Version 0.0.7 (Mon, 23 Mar 2009): |
73 | c5bd8d89 | Iustin Pop | - added support for offline nodes, which are not used as targets for |
74 | c5bd8d89 | Iustin Pop | instance relocation and if they hold instances the hbal algorithm |
75 | c5bd8d89 | Iustin Pop | will attempt to relocate these away |
76 | c5bd8d89 | Iustin Pop | - added support for offline instances, which now will no longer skew |
77 | c5bd8d89 | Iustin Pop | the free memory estimation of nodes; the algorithm will no longer |
78 | c5bd8d89 | Iustin Pop | create conditions for N+1 failures when such instances are later |
79 | c5bd8d89 | Iustin Pop | started |
80 | c5bd8d89 | Iustin Pop | - implemented a complete model of node resources, in order to |
81 | c5bd8d89 | Iustin Pop | prevent an unintended re-occurrence of cases like the offline |
82 | c5bd8d89 | Iustin Pop | instance were we miscalculate some node resource; this gives warning |
83 | c5bd8d89 | Iustin Pop | now in case the node reported free disk or free memory deviates by |
84 | c5bd8d89 | Iustin Pop | more than a set amount from the expected value |
85 | c5bd8d89 | Iustin Pop | - a new tool *hscan* that can generate the input text-file for the |
86 | c5bd8d89 | Iustin Pop | other tools by collection via RAPI |
87 | c5bd8d89 | Iustin Pop | - some small changes to the build system to make it more friendly; |
88 | c5bd8d89 | Iustin Pop | also included the generated documentation in the source archive |
89 | c5bd8d89 | Iustin Pop | |
90 | 9857c181 | Iustin Pop | Version 0.0.6 (Mon, 16 Mar 2009): |
91 | c5bd8d89 | Iustin Pop | - re-factored the hbal algorithm to make it stable in the sense that it |
92 | 9857c181 | Iustin Pop | gives the same solution when restarted from the middle; barring |
93 | c5bd8d89 | Iustin Pop | rounding of disk/memory and incomplete reporting from Ganeti (for |
94 | 9857c181 | Iustin Pop | 1.2), it should be now feasible to rely on its output without |
95 | 9857c181 | Iustin Pop | generating moves ad infinitum |
96 | 9857c181 | Iustin Pop | - the hbal algorithm now uses two more variables: the node N+1 |
97 | 9857c181 | Iustin Pop | failures and the amount of reserved memory; the first of which tries |
98 | 9857c181 | Iustin Pop | to ‘fix’ the N+1 status, the latter tries to distribute secondaries |
99 | 9857c181 | Iustin Pop | more equally |
100 | 9857c181 | Iustin Pop | - the hbal algorithm now uses two more moves at each step: |
101 | 9857c181 | Iustin Pop | replace+failover and failover+replace (besides the original |
102 | 9857c181 | Iustin Pop | failover, replace, and failover+replace+failover) |
103 | 9857c181 | Iustin Pop | - slightly changed the build system to embed GIT version/tags into the |
104 | 9857c181 | Iustin Pop | binaries so that we know for a binary from which tree it was done, |
105 | 9857c181 | Iustin Pop | either via ‘--version’ or via “strings hbal|grep version” |
106 | 9857c181 | Iustin Pop | - changed the solution list and in general the hbal output to be more |
107 | 9857c181 | Iustin Pop | clear by default, and changed “gnt-instance failover” to |
108 | 9857c181 | Iustin Pop | “gnt-instance migrate” |
109 | 9857c181 | Iustin Pop | - added man pages for the two binaries |
110 | 9857c181 | Iustin Pop | |
111 | 9857c181 | Iustin Pop | Version 0.0.5 (Mon, 09 Mar 2009): |
112 | bbd1d273 | Iustin Pop | - a few small improvements for hbal (possibly undone by later |
113 | bbd1d273 | Iustin Pop | changes), hbal is now quite faster |
114 | bbd1d273 | Iustin Pop | - fix documentation building |
115 | bbd1d273 | Iustin Pop | - allow hbal to work on non N+1 compliant clusters, but without |
116 | bbd1d273 | Iustin Pop | guarantees that the end cluster will be compliant; in any case, this |
117 | bbd1d273 | Iustin Pop | should give a smaller number of nodes that are not compliant if the |
118 | bbd1d273 | Iustin Pop | cluster state permits it |
119 | bbd1d273 | Iustin Pop | - strip common domain suffix from nodes and instances, so that output |
120 | bbd1d273 | Iustin Pop | is shorter and hopefully clearer |
121 | bbd1d273 | Iustin Pop | |
122 | 9857c181 | Iustin Pop | Version 0.0.4 (Sun, 15 Feb 2009): |
123 | bbd1d273 | Iustin Pop | - better balancing algorithm in hbal |
124 | bbd1d273 | Iustin Pop | - implemented an RAPI collector, now the cluster data can be gathered |
125 | bbd1d273 | Iustin Pop | automatically via RAPI and doesn't need manual export of node and |
126 | bbd1d273 | Iustin Pop | instance list |
127 | bbd1d273 | Iustin Pop | |
128 | 9857c181 | Iustin Pop | Version 0.0.3 (Wed, 28 Jan 2009): |
129 | bbd1d273 | Iustin Pop | - initial release of the hbal, a cluster rebalancing tool |
130 | bbd1d273 | Iustin Pop | - input data format changed due to hbal requirements |
131 | bbd1d273 | Iustin Pop | |
132 | c5bd8d89 | Iustin Pop | Version 0.0.2 (Tue, 06 Jan 2009): |
133 | c5bd8d89 | Iustin Pop | - fix handling of some common cases (cluster N+1 compliant from the |
134 | c5bd8d89 | Iustin Pop | start, too big depth given, failure to compute solution) |
135 | c5bd8d89 | Iustin Pop | - add option to print the needed command list for reaching the |
136 | c5bd8d89 | Iustin Pop | proposed solution |
137 | c5bd8d89 | Iustin Pop | |
138 | c5bd8d89 | Iustin Pop | Version 0.0.1 (Tue, 06 Jan 2009): |
139 | c5bd8d89 | Iustin Pop | - initial release of hn1 tool |
