The cluster was in trouble, and the disk space was full. I removed some old  
index data by running curl -XDELETE  
'localhost:9200/logstash-2014.04.28?pretty'. In the meantime, there were 2  
data nodes were out of the cluster. Not sure what happened. But after I  
restarted all the nodes in the cluster, including these 2 data nodes. I  
found some old index data on these 2 data nodes were not removed as  
expected, I could understand because they were out of the cluster when I  
performed the curl command at the first time. I can remove the newer index  
data, but cannot remove those old index data that should be removed when I  
ran curl command at the first time. How can I sync these index data in a  
cluster? I mean to remove those old index data by cluster on these 2 data  
nodes automatically. Or may I just run rm command to remove these old index  
data (logstash-2014.04.28 - logstash-2014.04.5.15)?

data node in trouble:  
-bash-4.1$ curl -XDELETE 'localhost:9200/logstash-2014.04.28?pretty'  
{  
"error" :  
"RemoteTransportException[[edc-prod-caredlogs-app1][inet[/10.63.64.176:9300]][indices/delete]];  
nested: IndexMissingException[[logstash-2014.04.28] missing]; ",  
"status" : 404  
}
