Notes
- Description: LDAP master failover
- Purpose: Install write caches on wp-master01/02, restart slapd
- Impact: outage for new user signups, node-assignment, and password changes
- Expected duration: 1 minute outage, 20 minutes for hardware install for each host
- Plan:
- stage config changes to all masters
- down wp-master VIP on current master (outage starts)
- tail -f ldap.log on secondary master, let syncrepl finish
- restart secondary master in primary mode (will also pick up new configs)
- bring up wp-master VIP on new master (outage finished)
- restart LDAP slaves (one at a time, per environment) to force-kick replication
- restart prior master in secondary master mode
