Log Server Cluster Status Red

Post by Sampath.Basireddy »

Storage on NLS Servers reached about 95% this morning and the cluster status turned red. I cleared up some space and now we have more than 10% free space.

I still see status is red and there are 10 Unassigned Shards. More than couple of hours, the shards doesn't seem to be changing.

Any suggestions.

The default low watermark for shards to be allowed to move is 85% usage.

To override this you would need to set the following in the /usr/local/nagioslogserver/elasticsearch/config/elasticsearch.yml on each node and then restart all nodes on the cluster

Code: Select all

cluster.routing.allocation.disk.watermark.low: 95%
