Version 0.0.7 (Mon, 23 Mar 2009):
2 
  - added support for offline nodes, which are not used as targets for
3 
    instance relocation and if they hold instances the hbal algorithm
4 
    will attempt to relocate these away
5 
  - added support for offline instances, which now will no longer skew
6 
    the free memory estimation of nodes; the algorithm will no longer
7 
    create conditions for N+1 failures when such instances are later
8 
    started
9 
  - implemented a complete model of node resources, in order to
10 
    prevent an unintended re-occurrence of cases like the offline
11 
    instance were we miscalculate some node resource; this gives warning
12 
    now in case the node reported free disk or free memory deviates by
13 
    more than a set amount from the expected value
14 
  - a new tool *hscan* that can generate the input text-file for the
15 
    other tools by collection via RAPI
16 
  - some small changes to the build system to make it more friendly;
17 
    also included the generated documentation in the source archive

  - initial release of the hbal, a cluster rebalancing tool


  		





  41
  59
  
    
  - input data format changed due to hbal requirements

Version 0.0.2 (Tue, 06 Jan 2009):


  		





  
  62
  
    
  - fix handling of some common cases (cluster N+1 compliant from the


  		





  
  63
  
    
    start, too big depth given, failure to compute solution)


  		





  
  64
  
    
  - add option to print the needed command list for reaching the

    proposed solution
