I am very happy to announce that source code for the final release of Pacemaker version 2.0.0 is now available at:
https://github.com/ClusterLabs/pacemaker/releases/tag/Pacemaker-2.0.0 The main goal of the change from Pacemaker 1 to 2 is to drop support for deprecated legacy usage, in order to make the code base more maintainable going into the future. Rolling (live) upgrades are possible only from Pacemaker 1.1.11 or later, on top of corosync 2 or later. Other setups can be upgraded with the cluster stopped. If upgrading an existing cluster, it is recommended to run "cibadmin -- upgrade" (or the equivalent in your higher-level tool of choice) both before and after the upgrade. Extensive details about the changes in this release are available in the change log: https://github.com/ClusterLabs/pacemaker/blob/2.0/ChangeLog and in a special wiki page for the 2.0 release: https://wiki.clusterlabs.org/wiki/Pacemaker_2.0_Changes Highlights: * Support has been dropped for heartbeat and corosync 1 (whether using CMAN or plugin), and many legacy aliases for cluster options (including default-resource-stickiness, which should be set as resource- stickiness in rsc_defaults instead). * The logs should be a little more user-friendly. The Pacemaker daemons have been renamed for easier log searching. The default location of the Pacemaker detail log is now /var/log/pacemaker/pacemaker.log, and Pacemaker will no longer use Corosync's logging preferences. * The master XML tag is deprecated (though still supported) in favor of using the standard clone tag with a new "promotable" meta-attribute set to true. The "master-max" and "master-node-max" master meta-attributes are deprecated in favor of new "promoted-max" and "promoted-node-max" clone meta-attributes. Documentation now refers to these as promotable clones rather than master/slave, stateful or multistate clones. * The record-pending option now defaults to true, which means pending actions will be shown in status displays. * The "Pacemaker Explained" document has grown large enough that topics related to cluster administration have been moved to their own new document, "Pacemaker Administration": http://clusterlabs.org/pacemaker/doc/ Many thanks to all contributors of source code to this release, including Andrew Beekhof, Bin Liu, Bruno Travouillon, Gao,Yan, Hideo Yamauchi, Jan Pokorný, Ken Gaillot, and Klaus Wenninger. -- Ken Gaillot <kgail...@redhat.com> _______________________________________________ Users mailing list: Users@clusterlabs.org https://lists.clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
