I'm not sure if there is a way to force one of your dedicated masters to be the active master instead of one of the four data/master eligible nodes. Try it, tell us what happens.

[image] hlcxpl: i need to set up 3 master node dedicate and 4 data node and master elegibles Any reason to set the data node as master elegibles? If you have 3 dedicated master nodes I see no reason to also have the master nodes as master elegibles. You can not choose the master, Elastic wil…

I didn't tested with Logstash and I'm not sure Logstash supports PEM keys with passphrase. What I use is the CRT file for the CA. use cacert => "/path/to/the/ca.crt" If this do not work you will probably need to regenerate all the certificates for your cluster withtout the --pass parameter.
