So, I'm in the process of testing LVS as a replacement to our current hardware load balancer. For now, I'm implementing this for POP/IMAP. I've run into a couple problems:
1) If I leave the virtual alone for a while and come back and try to make a connection, the connection times out. If I keep trying, then eventually a connection will be made and connections will be made successfully from that point forward. If no further connections are made to the virtual for a while (maybe 30-60 minutes?) then it happens again. Does anyone have any idea what might be going on here? The real servers are fine because they're the exact same servers that are being load balanced through the hardware load balancer. A tcpdump from the virtual shows the request coming in but no return packets. 2) Which brings me to my second problem... Where are the logs for LVS? I felt that the documentation suggested that I should check local0, but that log is completely silent unless I myself send a syslog message to local0. Lastly, I'm trying to get this all going without HA/ldirectord first so this is just straight LVS. Any pointers would be great.
