Oh dear. You really haven't grasped this have you?
1. Use fstab to PERMANTLY mount them at boot time before NFS even come up
2. use their partition UUIDs in fstab  to associate  each partition with 
a defined mount point.

e.g.

PARTUUID=0916c1e1-d006-4b19-9378-d687271d3612  /home               ext4 
   defau
lts,noatime  0       1
PARTUUID=aec7525a-1e13-4a52-a23f-d8a0d17f6da7  /home/Media 
ext4
  defaults,noatime  0       1
PARTUUID=778a9e44-03 /backup ext4    defaults,noatime  0       1
PARTUUID=778a9e44-06 /backup2 ext4    defaults,noatime  0       1
PARTUUID=778a9e44-05 /home/Media/Unedited ext4 defaults,noatime  0       1

These are all USB connected SSD partitions. They are all exported by NFS 
without problems.
