Problem
I have a file system exported from a Solaris 10 node as so:
share -F nfs -o root=144.111.132.36,anon=0 -d "opt" /opt
However the mounting system sees all "root" ownerships as "nobody" and can't manipulate the filesystem as root.
Solution
On the exporting server, turn off nfs4 in /etc/default/nfs:
Restart nfs.server and you should be good to go.
