Yep, just came here to post this myself and saw your message. The
problem is RPCNFSDOPTS is missing from the
/etc/default/nfs-kernel-server file.
The service file for the nfs server,
/usr/lib/systemd/system/nfs-config.service
includes this:
Wants=nfs-config.service
After=nfs-config.service
All nfs-config does is run this script:
ExecStart=/usr/lib/systemd/scripts/nfs-utils_env.sh
and the script reads the /etc/default/nfs* files and then
echo RPCNFSDARGS=\"$RPCNFSDOPTS ${RPCNFSDCOUNT:-8}\"
which then goes on the command line in the nfs-server service file:
ExecStart=/usr/sbin/rpc.nfsd $RPCNFSDARGS
So the solution is to add this line to /etc/default/nfs-kernel-server:
RPCNFSDOPTS="-N 2 -N 3"
Still unaccounted for is this variable in /etc/default/nfs-kernel-server:
# Runtime priority of server (see nice(1))
RPCNFSDPRIORITY=0
Which I can't find used anywhere in the service files. But in any case,
adding the RPCNFSDOPTS variable resolved the issue:
root@helios:~# cat /proc/fs/nfsd/versions
-2 -3 +4 +4.1 +4.2
Thanks!

I think what you're saying is that I need to add $RPCMOUNTDARGS to
the service file command line for rpc.nfsd?
Somehow you just need to make sure rpc.nfsd is also getting "-N 2 -N 3"
added to its commandline. I'm not sure of the right way to do that with
Debian's configuration.
I think the canonical way to do this is to edit
/etc/default/nfs-kernel-server
and set
RPCNFSDOPTS="-N 2 -N3"
or similar.
There were some issues in the past with the nfs init scripts
not picking up settings in that file correctly, but I believe
they have been corrected.
Kind regards
