Graylog dashboard is looking good due to below error

Hello Friends,

I have set up my Graylog on the docker container while getting the below error.


Error response from daemon: configured logging driver does not support reading.
rerouting shards: [high disk watermark exceeded on one or more nodes]
high disk watermark [90%] exceeded on high disk watermark exceeded on one or more nodes


this error means that one node in you elasticsearch cluster is facing disk utilization issues.

It’s a good thing apply a index rotation policy in your ES cluster to migrate and purge old data.

Hi Renaldo,

Disk space resolved but still same error.


Two likely mistakes here:

  1. you did not free enough space (or the disk is full again)
  2. you freed space in the wrong node

I have run this command after freeing up diskspace to get things rolling again:

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