问题
When I try to store anything in elasticsearch, An error says that:
TransportError(403, u'cluster_block_exception', u'blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];')
I already inserted about 200 millions documents in my index. But I don't have an idea why this error is happening. I've tried:
curl -u elastic:changeme -XPUT 'localhost:9200/_cluster/settings' -H 'Content-Type: application/json' -d '{"persistent":{"cluster.blocks.read_only":false}}'
As mentioned here: ElasticSearch entered "read only" mode, node cannot be altered
And the results is:
{"acknowledged":true,"persistent":{"cluster":{"blocks":{"read_only":"false"}}},"transient":{}}
But nothing changed. what should I do?

Try GET yourindex/_settings, this will show yourindex settings. If read_only_allow_delete is true, then try:
PUT /<yourindex>/_settings
{
"index.blocks.read_only_allow_delete": null
}
I got my issue fixed.
plz refer to es config guide for more detail.
The curl command for this is
curl -X PUT "localhost:9200/twitter/_settings?pretty" -H 'Content-Type: application/json' -d '
{
"index.blocks.read_only_allow_delete": null
}'

Last month I facing the same problem, you can try this code on your Kibana Dev Tools
curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'
I hope it helps

I had faced the same issue when my disk space was full,
please see the steps that I did
1- Increase the disk space
2- Update the index read-only mode, see the following curl request
curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

Tagging into this later on as I just encountered the problem myself - I accomplished the following steps. 1) Deleted older indexes to free up space immediately - this brought me to around 23% free. 2) Update the index read-only mode.
I still had the same issue. I checked the Dev Console to see what might be locked still and none were. Restarted the cluster and had the same issue.
Finally under index management I selected the indexes with ILM lifecycle issues and picked to reapply ILM step. Had to do that a couple of times to clear them all out but it did.

The problem may be a disk space problem, i had this problem despite i cleaned many space my disk, so, finally i delete the data folder and it worked: sudo rm -rf /usr/share/elasticsearch/data/
