Please tell me how to delete some indices from elasticsearch without starting starting it

I know the question. No need to ask again.

You can go in the data dir in nodes/0/indices if I recall correctly and remove from there.
The hard part will be to identify which directory name is the one you want to delete.

Normally you start elasticsearch and run the _cat/indices API to know.

Here I don't really know.

But before doing that could you share elasticsearch logs?

What type of instance and storage are you using? Might it be possible to extend storage?
