-Version 0.0.5:
+Version 0.0.6 (Mon, 16 Mar 2009):
+ - refactored the hbal algorithm to make it stable in the sense that it
+ gives the same solution when restarted from the middle; barring
+ rouding of disk/memory and incomplete reporting from Ganeti (for
+ 1.2), it should be now feasible to rely on its output without
+ generating moves ad infinitum
+ - the hbal algorithm now uses two more variables: the node N+1
+ failures and the amount of reserved memory; the first of which tries
+ to ‘fix’ the N+1 status, the latter tries to distribute secondaries
+ more equally
+ - the hbal algorithm now uses two more moves at each step:
+ replace+failover and failover+replace (besides the original
+ failover, replace, and failover+replace+failover)
+ - slightly changed the build system to embed GIT version/tags into the
+ binaries so that we know for a binary from which tree it was done,
+ either via ‘--version’ or via “strings hbal|grep version”
+ - changed the solution list and in general the hbal output to be more
+ clear by default, and changed “gnt-instance failover” to
+ “gnt-instance migrate”
+ - added man pages for the two binaries
+
+Version 0.0.5 (Mon, 09 Mar 2009):
- a few small improvements for hbal (possibly undone by later
changes), hbal is now quite faster
- fix documentation building
- strip common domain suffix from nodes and instances, so that output
is shorter and hopefully clearer
-Version 0.0.4:
+Version 0.0.4 (Sun, 15 Feb 2009):
- better balancing algorithm in hbal
- implemented an RAPI collector, now the cluster data can be gathered
automatically via RAPI and doesn't need manual export of node and
instance list
-Version 0.0.3:
+Version 0.0.3 (Wed, 28 Jan 2009):
- initial release of the hbal, a cluster rebalancing tool
- input data format changed due to hbal requirements
