CentOS NFS permission denied on mount

NFS mount results in a permission denied error. Check the export permissions, and those are right.

The solution is to add (on the exporting host):

nfsd /proc/fs/nfsd nfsd auto,defaults 0 0

to /etc/fstab and then type:

$mount -a

on the client.

not sure why this error exists.
