@Wayne-Workman HI Wayne know this is an old call but stumbled upon it when I had the same issue.
You were after a decent photo of the error for the wiki which I’ve not been able to get and adding in a codebox below just screws up but hopefully this workaround of text on a black background in notepad++ will do the trick :)
Also in my case for anyone else finding this later on I had moved the images directory to /home/fog/images and updated fog everywhere except for the /etc/exports file.
Amending that to read as
/home/fog/images *(ro,sync,no_wdelay,no_subtree_check,insecure_locks,no_root_squash,insecure,fsid=0) /home/fog/images/dev *(rw,async,no_wdelay,no_subtree_check,no_root_squash,insecure,fsid=1)
And then running
bypassed the error for me,.
