i have latest graylog on ubuntu (fresh installation)
after login i have error:
Elasticsearch nodes disk usage above low watermark (triggered an hour ago)
There are Elasticsearch nodes in the cluster running out of disk space, their disk usage is above the low watermark. For this reason Elasticsearch will not allocate new shards to the affected nodes. The affected nodes are: [127.0.0.1] Check Disk-based shard allocation | Elasticsearch Guide [master] | Elastic for more details.
i don’t have cluster and 5 gig back .
