Re: How to replace a zookeeper server ?
As long as the old quorum constitutes a quorum in the new cluster you should be fine.  

In the replace a dead node scenario you can reconfigure the survivors before bringing up the new node. That only works if you start with 5 nodes, but being down a node in a three node cluster is a problem for any admin actions you might take.
