It is a little bit different. Pacemaker is 1.0.4 right now. It can run with openAIS providing cluster communications. then all that remains of the "heartbeat" stack is some scripts and helper utilities from a "heartbeat-common" package. Or it can run with heartbeat providing cluster communications. As "heartbeat" used to have its own CRM, but you want to use its successor, the Pacemaker CRM, there needed to be a heartbeat package only providing the infrastructure layer, but with the CRM ripped out. heartbeat 2.99.x is equivalent to heartbeat 2.1.4 with some bug fixes to the infrastructure layer, and the CRM ripped out. Now the Pacemaker CRM can use the heartbeat communication infrastructure without conflicting with its own predecessor, the integrated-in-heartbeat CRM. More clear now? And YES. pacemaker (with heartbeat 2.99 providing infrastructure, or with openAIS providing infrastructure, at your choice) is _definitely_ much more "production ready" than any integrated-in-heartbeat CRM you may find. -- : Lars Ellenberg : LINBIT | Your Way to High Availability : DRBD/HA support and consulting http://www.linbit.com DRBD® and LINBIT® are registered trademarks of LINBIT, Austria. _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
