Index read_only_allow_delete can be set to true automatically when disk space is low. This allows writing to indexes again:

curl -X PUT "http://localhost:9200/_all/_settings?pretty" -H 'Content-Type: application/json' -d'
{                
    "index.blocks.read_only_allow_delete": false
}
'

fixes error:

[FORBIDDEN/12/index read-only / allow delete (api)]
