Version 0.0.6 (Mon, 16 Mar 2009):
2 
  - refactored the hbal algorithm to make it stable in the sense that it
3 
    gives the same solution when restarted from the middle; barring
4 
    rouding of disk/memory and incomplete reporting from Ganeti (for
5 
    1.2), it should be now feasible to rely on its output without
6 
    generating moves ad infinitum
7 
  - the hbal algorithm now uses two more variables: the node N+1
8 
    failures and the amount of reserved memory; the first of which tries
9 
    to ‘fix’ the N+1 status, the latter tries to distribute secondaries
10 
    more equally
11 
  - the hbal algorithm now uses two more moves at each step:
12 
    replace+failover and failover+replace (besides the original
13 
    failover, replace, and failover+replace+failover)
14 
  - slightly changed the build system to embed GIT version/tags into the
15 
    binaries so that we know for a binary from which tree it was done,
16 
    either via ‘--version’ or via “strings hbal|grep version”
17 
  - changed the solution list and in general the hbal output to be more
18 
    clear by default, and changed “gnt-instance failover” to
19 
    “gnt-instance migrate”
20 
  - added man pages for the two binaries

Version 0.0.5 (Mon, 09 Mar 2009):


  		





  2
  23
  
    
  - a few small improvements for hbal (possibly undone by later


  		





  3
  24
  
    
    changes), hbal is now quite faster


  		





  4
  25
  
    
  - fix documentation building


  		





  ......

  30
  
    
  - strip common domain suffix from nodes and instances, so that output


  		





  10
  31
  
    
    is shorter and hopefully clearer

Version 0.0.4 (Sun, 15 Feb 2009):


  		





  13
  34
  
    
  - better balancing algorithm in hbal


  		





  14
  35
  
    
  - implemented an RAPI collector, now the cluster data can be gathered


  		





  15
  36
  
    
    automatically via RAPI and doesn't need manual export of node and


  		





  16

    instance list

  - initial release of the hbal, a cluster rebalancing tool

  - input data format changed due to hbal requirements
