I want my backup directors to be real servers, and I've succeeded, so there's nothing I "need" at this point.
The problem with it routing when it's a backup is that it mungs up the incomming connections to the realserver running locally when the Master DR sends connections to it. I solved my problem by using netfilter marking to direct packets to be load balanced, and only marking packets when the unit is master, thereby working around the issue. My recomendation is that the backups not try to load balance until they're switched to master by the userspace stuff. This is an issue for me because all my units are "peers", and I want to the master director to be able to be any one of them so I can do nifty stuff like rolling firmware upgrades, with 0 downtime, etc. I'm sure my needs are rather specialized, and even then I was able to get them met, just by jumping through a few hoops, so great job!

If you know that already, what's missing from LVS that you need? > I just want a backup to sit there and collect data, I > don't want it to try and load balance anything until I > promote it! :) It doesn't loadbalance till you send it packets. It seems that you and I have a different idea about what's happening here and I don't know what you idea is. Can you straighten me out?
