Server migration recommendation? 3 nodes to 4 nodes

(SML) #1

Hi, right now my production servers consist of 3 nodes: A, B, C. I would like to add E, D and then get rid of A. What’s the best way to achieve this?

If I simply add E, D with the existing config and then remove A from the cluster when the status is green, would that work? My hunch is that it should but I would like to verify this before I proceed.

It will indeed.

Thanks — that’s handy!

When should I add the discovery.zen.minimum_master_nodes: 3 settings, which is currently set to 2? Should I add it to the 4th instance and then reboot the original 3?

Yep. You can also change it via API in the short term so you are protected along the way.
