Is there a way to replace a failed server using vnodes? I only had occasion to do this once, on a relatively small cluster. At the time I just needed to get the new server online and wasn't concerned about the performance implications, so I just removed the failed server from the cluster and bootstrapped a new one. Of course that caused a bunch of key reassignments, so I'm sure it would be less work for the cluster if I could bring a new server online with the same vnodes as the failed server.
