Problem

Elasticsearch is returning index queries with barfs like

{"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"}

Solution

Disk is beyond Elasticsearch's safety boundary. Indexes are put into read-only mode at this point.

Once you've dealt with the disk space issue (cleaned up, added more, whatever), you need to turn the indexing back into read-write mode:

# curl -XPUT -H "Content-Type: application/json" >>http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
