I restarted my cluster the other day, but something odd stuck, resulting in  
15/16 data nodes starting up an extra ES instance in the same cluster. This  
ended badly as there were two nodes with identical display names, the  
system locked up, etc.  
When restarting again, to my horror, we were missing shards. I quickly  
figured out that the missing shards had gotten moved into the second  
instance storage location.  
What is the best way to resolve this? Should we either spawn second ES  
instances on the culprit machines (with different instance names), or can a  
simple  
mv escluster/nodes/1/indices/data1/\* escluster/nodes/0/indices/data1/  
do the job?

Thanks!
