You have to run ZK on a at least 3 different machines for fault tolerance (a ZK ensemble). http://wiki.apache.org/solr/SolrCloud#Example_C:_Two_shard_cluster_with_shard_replicas_and_zookeeper_ensemble

Hi, I'm interested in setting up a solr cluster where each machine [at least initially] hosts a separate shard of a big index [too big to sit on the machine]. I'm able to put a cloud together by telling it that I have (to start out with) 4 nodes, and then starting up nodes on 3 machines pointing at the zkInstance. I'm able to load my sharded data onto each machine individually and it seems to work. My concern is that it's not fault tolerant: if one of the non-zookeeper machines falls over, the whole cluster won't work. Also, I can't create a shard with more data, and have it work within the existing cloud. I tried using -DshardId=shard5 [on an existing 4-shard cluster], but it just started replicating, which doesn't seem right. Are there ways around this? Thanks, Ranjan Bagchi
