Remove 2 nodes from a 4 nodes cluster

Elastic Stack Elasticsearch
1

Hi everyone,

I would like to reduce the number of my 4 Ubuntu master-eligible nodes cluster (version 6.8) to a 3 master-eligible nodes cluster.

In order to do this I have to temporarily remove 2 nodes from the cluster because I need to delete one node to get the disk space (it's VM VMware) and assign it to the other node.

What is the best way to accomplish this scenario?

I know that removing 2 nodes at the same time will bring my cluster on red state, I would like to avoid this situation.

Thanks!
