Last time I set it up it was on NT but I just checked and I think it may still be an option. looks like It's even supporting v4.1 in 2022 if I read this right.

As I recall and that's a real wildcard it doesn't matter what the server filesystem is, if it has an NFS driver it's a network file system and all translation, rights mappings etc. etc. is handled by the linux driver or windows MMC plug-in so everybody sees it their way. Think you can even run like 2, 3 and 4 at the same time while migrating or waiting for vendor catch-up.

Hi Linus,
Dunno but I'm sticking with NFSv4.
I'm not sure that's an option, and if it is an option, I'm pretty sure that it wouldn't be advisable. My Fedora boxes are all clients; the server is Windows Server 2012r2, and if you can replace NTFS/DFS with NFSv4, I'm pretty sure that will cause more problems than it solves.

But, if you think you understand what happened, that by all means enlighten me, because I haven't the slightest idea.
