[clug] NFSv4 "Invalid argument"

Hasty reply.

You haven't answered the question of why the shares need to be owned by
root. I'm still uncertain this is not an x/y problem.

You haven't posted /etc/exports. Please post the output of "showmount
-e" (anonymise if you feel it's necessary)

You are using references that are:-
;seriously outdated - best ignore advice that doesn't apply to v4[*1]
;RedHat based - which is not the Debian way[*2]

I don't understand the domain name references - that's not the problem
you referred to in the OP. "rpc.nfsd -H hostname"??

Please just click on the "Reply" button in your MUA instead of creating
a new post - I'm busy and a "bit thick" so the more work I've got to do
to try and follow the conversation *and* make sense of it - the less
likely any reply will help you.

I'd suggest filtering out results earlier than 2003 (RFC 3530)

The section on User ID Mapping may be informative

... or forming the same opinion of NFS v4 as Theo de Raadt :D

A possible resource might be https://forums.openfiler.com/ if you
haven't tried already. It's a NAS I've avoided, and I haven't touched
VMWare for a looong time.

An excellent project and book.
