Change your topology script? One thing about rack awareness. You never want to have an unbalanced configuration. The caveat is if your uplinks between the ToR Switch are 'fat' enough. (4 10GBe should do it.)
If you watched your system with the one machine on a separate rack (assuming it was also on a separate switch) you'd see a major network bottle neck. (We use Ganglia) If you're seeing the rack count wrong, you could just bounce the cloud and it should show only two. Note: Deprecating a machine can take a long time. You may want to consider just killing the node, waiting till the cluster recognizes that its down and I believe just kicking off an FSCK or maybe running the balancer program will clean that up faster than deprecating.

It was the only server in this rack so I decommissioned the server. fsck shows only 2 racks however topology shows 3 racks. How can I fix this?
