Good question, it's not. There are additions such as a Troubleshooting chapter planned for the new "Pacemaker Administration" document, when that mythical available time appears, and that would be a good place for it. A transition is simply the set of actions Pacemaker plans in response to a new situation. The situation is defined by the CIB (including status section). Whenever something interesting happens (configuration change, unexpected action result, or cluster re-check interval), the scheduler uses the current live CIB to calculate what (if anything) needs to be done, and that is a transition. > > Regards, > Ulrich -- 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
