Changing the number of replicas on the flight

Graylog Central (peer support)
5

Thanks for you guys’ pointer.

  • I am able to run following command to change the replica from 0 to 1
curl -XPUT -d '{"number_of_replicas": "1"}' http://mysyslog01:9200/graylog_4*/_settings
  • I can see the replica(yellow) got created in Elasticsearch head’s web GUI.

  • After sync , sized doubled from 8/9 to 16/17GB.
 curl -XGET 'mysyslog02:9200/_cat/indices?v&pretty'

  • Question is what do I do with repica=0 setting in /etc/graylog/server/server.conf
[root@syslog01 server]# egrep -v '^#|^$'  /etc/graylog/server/server.conf |grep replica
elasticsearch_replicas = 0
[root@syslog01 server]#
