Can anyone explain this? How can it be fixed? Do some services need to

The server is "weather". This log is from the client:
# mount -t nfs weather:/home/jonrysh /mnt/weather
# ls /mnt/weather
Desktop Documents Downloads Music Pictures Public Templates Videos grub2
# umount /mnt/weather
# mount -t nfs4 weather:/home/jonrysh /mnt/weather
mount.nfs4: mounting weather:/home/jonrysh failed, reason given by server:
No such file or directory

Thanks in advance - jon
NFSv4 works very differently from previous versions. You should be
able to Google up plenty of documentation.
The key point is that you can't just switch between v3 and v4
without reconfiguring things.
possibly off-topic but a long, long, *long* time ago, i wondered if
you could set up a network using *exclusively* NFSv4, and found it was
impossible -- at least one of the client programs required some
earlier version of NFS even if it wasn't being used.
any clarification on whether one can run a *purely* NFSv4 network?
I see no reason why not. On all machines at one site nfs4 is used to provide
idmap capability. That's the only kind of mount used, and a long look with
wireshark shows all nfs packets were V4, so I empirically conclude it works.
You have to diddle the firewall to get nfs3 to work IIRC.
