Hi all,
We noticed that there are old shards still being stored on our opensearch DB due to which the disk space is getting low.
Is it safe to remove these shards from 2023 ? If yes, how can we safely remove them without affecting the opensearch server ?
Hi Arun,
If the data from those shards is no longer required, the corresponding indices can be removed using the Delete Index | Elasticsearch Guide [6.8] | Elastic API only.
You can also delete them using Elasticvue - Elasticsearch gui, which allows you to delete multiple indices at once.
Note that you may never delete every index of a specific type (i.e. with the same alias), as it will cause confusion during DataMiner startup.
Depending on the version, some improvements have been made. Starting from DataMiner 10.4.2 or DataMiner 10.3.0CU11, the suggest indices are no longer generated.
These indices were only used in a limited manner and can be a good target for elimination if they create too much overhead.
Feel free to send me a message so we can sync in person.
