A node in my elasticsearch has full disk

Elastic Stack Elasticsearch

Hi all, I have a elasticsearch cluster with 10 node, one node in my elasticsearch had full disk and it was removed from cluster by elasticsearch. the Disk of other nodes in my cluster still have 70% disk. How to I can rejoin failed node to cluster?
It seem like the assign process to balance the disks in my cluster has failed

Hi,

Before attempting to rejoin the node, make sure to free up enough disk space on the node that was previously removed. You can delete unnecessary files or move data to another disk.

To avoid similar situations in the future, consider adjusting the disk thresholds in your Elasticsearch configuration. You can use the cluster.routing.allocation.disk.watermark settings to control when Elasticsearch starts to prevent shard allocation due to low disk space.For example, you can set the following in your elasticsearch.yml file:

cluster.routing.allocation.disk.watermark.low: 90%
cluster.routing.allocation.disk.watermark.high: 95%

Regards
