New Elasticsearch user here and trying to integrate it into a project that I'm working on. Currently just working locally with Elasticsearch using Ubuntu 18.04.
I have been working for the past week or so, creating indexes, indexing documents, searching and just generally getting familiar with things.
However, I have now hit a problem:
[cluster_block_exception] blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];
it appears that my index is being forced into read-only mode due to 95% of disk space being used.
However, I don't understand this or know how to rectify it, I have deleted all my indexes bar the 4kb .kibana index so I don't understand the used disk space?
Would really love it if anyone can shed some light on this, i'm stuck, and please forgive my ignorance!
