When I try to start Kibana on Windows 10 I get: [fatal][root] { [cluster\_block\_exception] blocked by: [FORBIDDEN/12/index read-only / allow delete (api)] After that Kibana exists the batch script. Can someone please advise. ---

Hi, Could you please share some surrounding errors? Also check if you're cluster health is ok. For example if there is enough free disk space, etc. You need to figure out which index is read-only then you may find Infos in the logs why this happened. Regards, Simon ---

Thanks for the reply. The cluster is yellow and two the four nodes are at 95% diskspace. So the index is read only, but I don't understand why Kibana can not connect. ---

95% Free or used? If it's 95% used and you can't free up space you could increase the storage thresholds, but that's not recommend as a solution, more a quick & dirty fix. The error looks like kibana want to write into a index. Are there any details which index is read-only? The best would be if you post the logs from ES and Kibana around the Error. ---

Could you also share the results of the /\_cat/indices/ API. Then we could see the status of your indices. ---

As I thought, there are multiple unassigned shards. So you need more disk space. You can add physical storage (best) or delete data, either deleting old data or maybe delete replicas if not needed. ---

Thanks for your answer, I appreciate them. There 4 nodes, two of the nodes are above 95%, however 1 one of the nodes is at 81%. Is there a way to move the unassigned to the node at 81%? Also is there an explanation why Kibana cant connect? ---

If you want you can route the shards manually. By default elastic search try to make the best routing. Maybe it's not possible because the replica would be on the same node as the primary. Could you check your cluster settings, especially the setting `cluster.routing.allocation.enable` setting, may it's disabled. Kibana couldnt start because it try to write data into an index. After reaching a storage threshold elastic search set the indices in an read only mode, so no new data could be added, that's the reason. ---

looks good, so routing is enabled. Your only option now is to increase the storage or delete old Data. ---
