-Version 0.0.5:
+Version 0.1.3 (Fri, 05 Jun 2009):
+ - Fix a bug in the ReplacePrimary instance moves, affecting most of
+ the tools
+
+Version 0.1.2 (Tue, 02 Jun 2009):
+ - Add a new program, “hspace”, which computes the free space on a
+ cluster (based on a given instance spec)
+ - Improvements in API docs and partially in the user docs
+ - Started adding unittests
+
+Version 0.1.1 (Tue, 26 May 2009):
+ - Add a new program, “hail”, which is an iallocator plugin and can
+ allocate/relocate instances
+ - Experimental support for non-mirrored instances (hail supports them,
+ hbal should no longer abort when it finds such instances and simply
+ ignore them)
+ - The RAPI port and/or scheme can be overriden now, and even “file://”
+ schemes can be used if the message body has been saved under the
+ appropriate name
+ - Lots of code reorganization, esp. rewritten loading pipeline
+ - Better data checking and better error messages in case validation
+ fails; tools now consider nodes with error in input data (‘?’
+ returned by ganeti) as offline
+ - Small enhancement to the makefile for simpler packaging
+
+Version 0.1.0 (Tue, 19 May 2009):
+ - Drop compatibility with Ganeti 1.2
+ - Add a new minimum score option (with a very low default), should
+ help with very good clusters (but is still not optimal)
+ - Add a --quiet option to hbal
+ - Add support for reading offline nodes directly from the cluster
+
+Version 0.0.8 (Tue, 21 Apr 2009):
+ - hbal: prevent mismatches in wrong node names being passed to -O, by
+ aborting in this case
+ - add the ability to write the commands (-C) to a script via
+ (-C<file>), so that it can be later executed directly; this has also
+ changed the commands to include the ncessary -f flags to skip
+ confirmations
+ - add checks for extra argument in hbal and hn1, so that unintended
+ errors are catched
+ - raise the accepted “missing” memory limit to 512MB, to cover usual
+ Xen reservations
+
+Version 0.0.7 (Mon, 23 Mar 2009):
+ - added support for offline nodes, which are not used as targets for
+ instance relocation and if they hold instances the hbal algorithm
+ will attempt to relocate these away
+ - added support for offline instances, which now will no longer skew
+ the free memory estimation of nodes; the algorithm will no longer
+ create conditions for N+1 failures when such instances are later
+ started
+ - implemented a complete model of node resources, in order to
+ prevent an unintended re-occurrence of cases like the offline
+ instance were we miscalculate some node resource; this gives warning
+ now in case the node reported free disk or free memory deviates by
+ more than a set amount from the expected value
+ - a new tool *hscan* that can generate the input text-file for the
+ other tools by collection via RAPI
+ - some small changes to the build system to make it more friendly;
+ also included the generated documentation in the source archive
+
+Version 0.0.6 (Mon, 16 Mar 2009):
+ - re-factored the hbal algorithm to make it stable in the sense that it
+ gives the same solution when restarted from the middle; barring
+ rounding 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
-Previous version was initial announcement.
+Version 0.0.2 (Tue, 06 Jan 2009):
+ - fix handling of some common cases (cluster N+1 compliant from the
+ start, too big depth given, failure to compute solution)
+ - add option to print the needed command list for reaching the
+ proposed solution
+
+Version 0.0.1 (Tue, 06 Jan 2009):
+ - initial release of hn1 tool
