I was just wondering how other people are dealing with this issue and thier content switches.
At $workplace, we use a Cisco CSM. It allows the network guy to administratively take a node (RIP) out of service even if the CSM would normally send traffic to it. This allows me to either bring up a new node and let it sync or to debug a problem with a specific node while slapd is still running and accepting connections.
Whenever I need to do maintainence on one of the nodes, the network guy is able to take the RIP out of service and clear the connections to it so that all clients will immediately reconnect to the VIP and land on one of the other nodes.
So far, this approach works for us. We've been using it since we deployed OpenLDAP about 2 years ago.
