NFS not working

Had a power outage and My Cloud which has 3 My Book drives plugged into it. I had to do a 40 second restart now my PC see’s all drives and drives are mapped and working. Now my network issue I have Raspberry Pi’s all over the house which uses KODI 2 of the 3 drives can see NFS drives to stream media but the 3rd drive is seen but the folders holding the media is not showing up I have rebooted the network and my PC has no problems. Just cant get the one drive to show the media on NFS any suggestions ?

Bump ^^^ Know one has no idea why one drive is not seen using NFS on the network ? while it shows fine on PC mapped drive
