Hi all, We have a cluster of 4 nodes, and we constantly add new indexes and remove old ones in a daily basis operation. We had a node down for 3 days, and when starting it again it just added the indexes it had. The thing is that the name of the new indexes we create everyday depend on the date (ex: my\_index\_name\_20141203), so when this node started again it just didn´t find any inconsistence within its indexes (already deleted in the cluster) and it added them again. So the question is: Is there any way to remove the data when a given node fails? so it starts as if a new empty node has been added to the cluster.
