I wanted to know, how to close existing index location (ready-only mode) and open new index location for writing the index data? Consider a use case that, I want to chage my storage type in which old data will remain on the existing drive and new data will write to a new location. I wanted to read the data from old as well as new index location at the same time. ---

Hi, If I understood correctly, you can make your old index in read-only mode. `PUT /my_old_index/_settings { "settings": { "index.blocks.write": true } }` Writing operations will be blocked and you can start to write documents in your new index ---

Does that mean you can't put index "location" in read only mode. You can put only Index in read only mode in Elasticsearch? ---

You cannot have a single node that has this type of storage setup. You will need multiple nodes to do this. You should also look at using [ILM][ILM: Manage the index lifecycle | Elasticsearch Guide [7.12] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/index-lifecycle-management.html)) to handle this for you automatically. ---

Can't we add disk to a node i.e. comma separated field in path.data to expand the storage on a existing node. Note: It's a single node elastic cluster per installation of our application. ---

Yes but Elasticsearch will treat it exactly the same as the other path. ---
