When changing mappings or index settings, we may need to re-index the existing indices to ensure there are no mapping conflicts.
One way to do this by using the following experimental example script:
Pull down the script to your Security Onion box:
Make the script executable:
sudo chmod +x so-elastic-reindex
Re-index all indices matching
logstash-*, pulling the appropriate
refresh_interval from the template named
logstash in Elasticsearch:
sudo ./so-elastic-reindex -i "logstash-*" -t "logstash"
The script should then progress to re-index the matching indices, and inform you when it has completed.
Abnormal execution of this script may result in data loss– there are NO GUARANTEES this process will work perfectly for you.
