We are trying to mirror a volumes over a geographical zone using DRBD (and Ubuntu 11.10). We are using elastic IP's - however there is no local interface for Elastic IP's - only an interface for a local IP. Thus, DRBD will not work as it needs an interface.
I've thought about using VIP or VPN to be able to use local IP's, but that would degrade the connection as its another layer.
Any thoughts or ideas?
[US EAST 1] [US WEST 1] [EC2-INSTANCE] -> [ELASTIC-IP] -> DRBD <- [ELASTIC-IP] <- [EC2-INSTANCE] *no eth interface* *no eth interface*
Edit: Alternative solutions (to DRBD/Clustering/Replciating) are more than welcome!
