You are running low on disk space.

[idris]

i extended space disk but it doesn't work ,i ve got the same problem when i create an index,this is my log from elasticsearch

org.elasticsearch.cluster.block.ClusterBlockException: blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];

the main error (output) when i use mapping for my index is

{"error":{"root_cause":[{"type":"cluster_block_exception","reason":"blocked by: 
[FORBIDDEN/12/index read-only / allow delete 
(api)];"}],"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read- only /  (allow delete (api)];"},"status":403

You need to manually remove the read only mode. See https://www.elastic.co/guide/en/elasticsearch/reference/6.7/misc-cluster.html

BTW it seems that you are using a 6.0.0 version. If so, you should really consider upgrading.
