Hi Rob, I am using heartbeat 2 to run an HA OpenLDAP system. The cluster has two nodes, one designated as the master and the other as a slave. Thus far it has been very stable, and handles failover quite well. In a nutshell, this is how it is set up.
- Both nodes have a two ldap configurations, one for running as the master, one for running as the slave. I had to write a couple of OCF scripts for each service (master and slave). - one VIP is used, it is bound to the master ldap service using a colocation. The VIP also has a place defined, node1 should be the master unless something bad is happening. - a second colocation is used to ensure the master and slave do not try to start on the same node - I leverage the OpenLDAP replication feature to ensure the slave node is up to date. If the primary is to fail, or is placed in standby mode, OpenLDAP is stopped (as the slave) and restarted as the master, and of course the VIP moves as well. This momentary blip is cushioned by the fact that I am running nscd on all of my ldap connected nodes.
