Let's see...
The server is CentOS 6. There's nothing
fancy about the setup; rather than running an account sync like NIS or
LDAP, I just make sure that both computers have the same users with the
same user id's on both computers (it's a home network setup with both
computers sitting right next to each other with a switch between them,
so I can guarantee that). I'm using the same fstab options I normally
use: hard, intr, rsize=8192, wsize=8192, tcp, nfsvers=3 . But for
whatever reason, I get this message whenever I try to mount the drive.
