[Pacemaker] ANNOUNCE: Pacemaker 0.6.6 now available (bug-fix only release)

[Andrew Beekhof]

Time for another Pacemaker bugfix-only release...

Packages for Pacemaker and it's immediate dependancies can be  
downloaded from the usual location:
   http://software.opensuse.org/download/server:/ha-clustering

The source can be obtained from:
  http://hg.clusterlabs.org/pacemaker/stable-0.6/archive/Pacemaker-0.6.6.tar.bz2

For a breakdown of the available packages and what parts are optional,  
please refer to

The main focus of this release was the inclusion of STONITHd (at the  
request of its maintainer) from Heartbeat.

The inclusion of STONITH required that we update the Heartbeat  
packages and so they have been refreshed with 2.99.0.
There are some distributions that currently cannot build due to an  
insufficiently recent version of glib (the lrmd makes use of  
g_hash_table_find which is a recnt addition to the glib API).  Dejan  
has promised to look into a workaround.

Also updated was OpenAIS.
In the past, we used the development branch as it contained the  
various patches needed to support Pacemaker.
Unfortunately, in our opinion, it is not yet ready for prime-time.

The good news however is that we've backported the required patches to  
'Whitetank', their stable series.
The result has been extremely encouraging and I would have no  
hesitation recommending it's use (I have spent much of the last 2  
months running OpenAIS-based clusters with 8 nodes and approximately  
60 resources).
