OS X Mavericks: Connecting to ZFS on Ubuntu Through NFS

I have a working zpool and dataset set on my home server. I want to setup NFS to access ZFS over my home network on my Mac. The server is running Ubuntu 14.04; my Mac is running OS 10.9.2 Mavericks.

On the Ubuntu side, I have...

• # apt-get install nfs-kernel-server
• # zfs set sharenfs=rw=@192.168.0.0/24,insecure tank/documents
  • should allow 192.168.0.0 - 192.168.0.255
  • insecure is needed so the mac connects on ports bigger than 1024
• # zfs share tank/documents
• # service nfs-kernel-server start

  commented out && grep -q '^[[:space:]]*[^#]*/' $export_files in /etc/init.d/nfs-kernel-server because I can't start the server with an empty /etc/exports/ file

• # showmount -e to verify directory is mounted

The output of showmount -e is this.

Export list for ubuntu1404:

/tank/documents *

On the Mac side, I have...

• $ rpcinfo -p 192.168.0.3 to verify NFS is visible on the network
• $ mount -t nfs 192.168.0.3:/tank/documents /Users/me/Remote

This last step is where I'm stuck. I keep getting "Operation not permitted".

I've been reading around, but I've only found old tutorials that use NFS Mounts from Disk Utility. Does anyone have any up-to-date tutorials?
