DFS should be accessible even if primary DC is offline

I have a question regarding DFS

Current situation:
Our primary DC hosts the DFS. When the primary DC goes offline. The DFS namespace is not accessible.

Goal:
If the primary DC goes offline, the DFS namespace should be accessible. I do not want to replicate the files to another server. My only goal is that the namespace is working.


Does some of you guys know how to achieve that?

Thank you in advance!

You need a domain based DFS root with at least one other Namespace server.

I have a domain based dfs root ( \\domainname\host ) , but I do not know how to replicate only the dfs namespace without copying the files.

You use the DFS Management console to add a second Namespace server. This Microsoft Article explains
