I have a large graylog open infrastructure that has been running for years. I want to move over to the datanodes from opensearch. On my opensearch nodes, I have multiple mountpoints that for the opensearch data because our data sets are really large. I have between 2 mount points on the opensearch nodes that are 2 TB is size. The variable in the elasticsearch.yml, path.data, is setup like this:
path.data: /elastic01, /elastic02
When I try and do the same in the datanode config file, datanode.conf I get errors.
opensearch_data_location only allows for a single location.
How do I point the datanode configuration to see all the opensearch data volumes so that I can do the migration?
