Migrating to datanodes from opensearch

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?

Greetings! Today I learn that Elasticsearch offered this!

As far as I can tell this is a deprecated setting:

Support for multiple data paths was deprecated in 7.13 and will be removed in a future release.

That section also offers some helpful tips on how to work around this setting being deprecated.

Hope this is helpful, let us know if you have any questions.
