I’m trying to add a new FST node with a new storage to my current test environment.
I’ve already configured the server and it’s up and running, but I’m kind of lost about how to add a new host running FST only, as I understand that I have to do.
Could anyone help me on the exact steps to do it?
You can probably start having a look over this page, that provides a reasonable guide for what needs to be done once you install a new instance. https://eos-docs.web.cern.ch/diopside/manual/getting-started.html
There are some scripts there that perform individual actions like adding file systems or nodes to the view that you might want to look into in order to get a better understand how things work.
You can also check our docker setup that we use heavily for all CI related builds and tests, where you have a pretty distilled recipe for starting and configuring a full EOS instance. More info here: https://eos-docs.web.cern.ch/quickstart/docker_image.html
