The steps for this procedure are as follows: Fill the Elasticsearch data disk until it exceeds the high disk watermark with this command: allocate -l9G largefile. Verify the high disk watermark is exceeded by reviewing the ES log. Mark the indices as read-only if you haven't already.

High Watermark This defaults to 90% disk usage. Once a node has breached this watermark, Elasticsearch will begin to relocate shards away from that node and onto others (assuming there are other nodes available that have not reached this threshold as well).

Elasticsearch uses a low disk watermark to ensure data nodes have enough disk space for incoming shards. By default, Elasticsearch does not allocate shards to nodes using more than 85% of disk space. To check the current disk space of your nodes, use the cat allocation API.

The low watermark represents the minimum amount of available free space allowed on a node before Elasticsearch begins taking action to prevent reaching disk capacity. This defaults to 85% disk usage. Once a node has breached this watermark, Elasticsearch will no longer allocate shards to that node.

Elasticsearch uses a low disk watermark to ensure data nodes have enough disk space for incoming shards. By default, Elasticsearch does not allocate shards to nodes using more than 85% of disk space. To check the current disk space of your nodes, use the cat allocation API.

There are various “watermark” thresholds on your Elasticsearch cluster. As the disk fills up on a node, the first threshold to be crossed will be the “low disk watermark”. The second threshold will then be the “high disk watermark threshold”. Finally, the “disk flood stage” will be reached.

(Dynamic) Controls the flood stage watermark, which defaults to 95%. Elasticsearch enforces a read-only index block ( index. blocks. read_only_allow_delete ) on every index that has one or more shards allocated on the node, and that has at least one disk exceeding the flood stage.
