comment Ansible/Capistrano with fixed sudo command ("sudo su -")
So you can't modify what commands you can use with sudo, but sudo su is allowed? What?

comment How to join local computer to azure virtual server domain?
I shudder to think of your egress data charges when moving a file server to Azure - consider OneDrive for Business instead. Also, you probably dont want to route all internet-bound traffic to Azure. That's another great way to incur a large egress traffic bill.

comment Is DFSR designed for use for Disaster Recovery?
How does storage replication or SAN replication solve the problems that you just identified with DFS-R? They are all vulnerable in the same way.

Any good DR plan has multiple layers to it. DFS-R can ensure that critical shares are available quickly while proper backups (and the ability/equipment to restore them at the DR site) can protect you from the scenario you've described.

Think about non-shared resources like home directories, read-only archives, etc. Those are all excellent candidates for both DFS-R and DFS-N. Additionally, you can use a namespace to direct all users at a single replica and then flip it to the other in the event of a failure. There's no mandate that the load be evenly distributed in a DFS-N scenario.

[...]conflicts especially if both servers are being used like a proper failover (so users are hitting both servers at once). - The DFS-R documentation is very clear that it is not a good solution in scenarios where the same file is accessed on multiple replicas by different users. In that case, a proper collaboration solutions (like a SharePoint document library) is appropriate.

What are you looking to protect with DFS-R? Just file shares?
