I'm testing elasticsearch 0.19.8 on a 8 node cluster. Each node has three  
physical drives but only two of the three drives have a significant amount  
of data being written to them even though all three are specified by  
path.data: in elasticsearch.yml. /hadoopdata2/elasticsearch and  
/hadoopdata3/elasticsearch are being written to as  
expected. /hadoopdata1/elasticsearch does not seem to have anything  
substantial written to the indices directories. I'm sure I'm just missing  
something basic, any ideas? See examples below. FYI I'm using  
a decommissioned HBase cluster for our tests in case you were wondering  
about the directories I'm using for ES data.

from elasticsearch.yml  
path.data:  
/hadoopdata1/elasticsearch,/hadoopdata2/elasticsearch,/hadoopdata3/elasticsearch

Any help at all would be very appreciated.

Has anyone actually tried using 3 drives per node?
