So the other day I was trying to configure a Mac server to export the /Users directory and I kept getting the error mentioned above ‘No path to directory’, which was odd, but it seems that NFS is not a fan of aliases, and I had moved the Users directory onto another hard drive (as I had switched to faster SSD’s for the System Drives) and aliased it to /Users

The solution was to share the new location of the Users folder which I had on a Volume named Data, so sharing /Volumes/Data/Users as Users served the same purpose as I was looking for, and NFS was happy with this.

So long story short, if your NFS shares are throwing up this error, look for aliases and reshare the direct location.
