Failed to add external storage via NFS

[Alan Lim]

I’m just set up Fog on Debian OS and installed it on the ESXi 7. Due to limited storage space, I would like to add an external NAS (Synology) as a storage node.
Upon PXE boot from the client, the NFS failed to mount and below is the message.
Reason: mount: mounting 172.20.149.70:/volume1/Fog-Master/dev on /images failed: Permission denied.
But I was able to mount it from the Debian which hosts the Fog server. Below is the command.
mount -t nfs 172.20.149.70:/volume1/Fog_Master /mnt (configured Synolog NFS to accept anonymous)
Below is the Fog Storage setting.
IP Address: 172.20.149.70
Image Path: /volume1/fog_Master
Management Username: Synology admin ID
Management Password: Synology admin password

Why is Debian able to mount but Fog can’t?
I appreciate it if someone would advise me on what I miss. Thank you

@Alan-Lim Lets run through this tutorial and compare it to your settings: https://forums.fogproject.org/topic/9430/synology-nas-as-fog-storage-node

@george1421 Thank you for the guide link. The FOG is able to mount the external NFS as a storage node. However, there were errors that appeared after the end of the cloning. It doesn’t seem stable to me. Also, understand that the storage node might break if the FOG version is upgraded to the next version.
Therefore, at this moment, I have set up a physical machine instead of a VM to eliminate the issues.
