What is the “external hard drive” ? Is it a stand alone NAS or plugged into another computer? I’m confused.

You need to make sure the “Storage Node” allows annon access to it’s ‘/fogstorage’ NFS share.

The error ‘Permission Denied’ tells you straight away that it does not have access to that share.

Try booting into debug mode and manually mounting the NFS Share
