Remove server for old architecture


(Arcocide) #1

Hi everyone,

I have a old cluster Graylog2 and I would like to keep only one server with data.
This cluster contains 3 server with 2.7 TB.

For free up space I woulk like to remove 2 servers and keep only one server.
Is it possible ? and how ?

Or just delete data on 2 servers and shutdown the 3 servers ?

How did you install Elasticsearch?

Hi Jochen,

First thanks for your time :slight_smile:

This is all my configuration :

  • 3 nodes
  • 2 write index :

graylog_0: 4 sharding / 180 GB

graylog_1 : 3 sharding / 2.7 TB !!

Is it possible to group all data on a single server ?

That still doesn’t answer my question.

But anyway, just follow the blog post I’ve posted before.
