To move Elasticsearch data (and logs):

1. Determine the current location of your data files by running the following command:

   > curl "localhost:9200/_nodes/settings?pretty=true"

   With Octopus Server installation, the default folders are /var/lib/elasticsearch and /var/logs/elasticsearch
   
   

2. Create a new directory structure. For example:

   > cd /opt/<new location>/ > mkdir elsdata

   (If you want to migrate the logs, create an additional folder mkdir elslogs)
   
   

3. Stop the sdomcbe service by running the following command:

   > systemctl stop sdomcbe

4. Stop the Elasticsearch service by running the following command:

   > systemctl stop elasticsearch

5. Navigate to the current data directory (as determined in Step 1), and copy files to the new location. For example:

   cp -RP * /opt/<new location>/elsdata/

   (If you are migrating the logs, copy those files to elslogs)
   
   

6. Change ownership on the new directory to Elasticsearch:

   > chown -R elasticsearch:elasticsearch /opt/<new location>/elsdata/

   (If you are migrating logs, run the same command for elslogs)
   
   

7. Change ownership on the sdo directory to sudo chmod o+rx /opt/sdo/
   
   

8. Edit the data path of the elasticsearch.yml file:

   > vi /etc/elasticsearch/elasticsearch.yml

   Change the path.data data parameter to path.data:/opt/<new location>/elsdata/
   
   

   (If you are migrating logs, change the path.logs data parameter as well.)
   
   

9. Start the Elasticsearch service by running the following command:

   > systemctl start elasticsearch.service

10. Start the sdomcbe service by running the following command:

    > systemctl start sdomcbe
