I just started to use elasticsearch and created a small cluster (2 machines) filled with some index data. So far everything works well. Now I have to duplicate the cluster on another two machines and hopefully I do not have to index everything again. I did one-to-one copying for the data directory from the old cluster to the new cluster. After I restarted the cluster, my client code (in pyes) shows error "IndexMissingException: [test-profile] missing", where "test-profile" is the index name. Since the data directory contains mata info, I thought restarting the cluster with copied data should automatically work. Now it seems not the case. Could someone point out what could be the potential problem here? Thanks. -- View this message in context: [http://elasticsearch-users.115913.n3.nabble.com/Duplicate-an-elasticsearch-cluster-tp4018633.html](http://elasticsearch-users.115913.n3.nabble.com/Duplicate-an-elasticsearch-cluster-tp4018633.html) Sent from the ElasticSearch Users mailing list archive at [Nabble.com](http://Nabble.com). ---
