I believe NFSv4. On the machine that contains the physical disks (is
that the "server" or the "NSF mount"?) the relevant line from /etc/fstab
seems to be
UUID=bde58f42-4ac4-4763-b0a8-f83723f0e2a0 /home ext4 defaults 1 2
while on my front-end machine its
mseas-data2:/home /home nfs defaults 0 0
where mseas-data2 is the name of the machine that contains the physical
disks. Note that it isn't just root that's becoming "nobody" but all
the users
Thanks
