To be honest I don't know what the expected outputs would be however I assume all 
three should show up if mounted, as they are at the moment:

julian@Cerce ~ $ mount

[extraneous info sipped]
192.168.1.3:/volume1/PERSEPHONE on /media/julian/PERSEPHONE type nfs
(rw,relatime,vers=3,rsize=8192,wsize=8192,namlen=255,hard,proto=tcp,timeo=70,retrans=2,sec=sys,mountaddr=192.168.1.3,mountvers=3,mountport=892,mountproto=udp,local_lock=none,addr=192.168.1.3)
192.168.1.3:/volume1/DIANA on /media/julian/DIANA type nfs
(rw,relatime,vers=3,rsize=8192,wsize=8192,namlen=255,hard,proto=tcp,timeo=70,retrans=2,sec=sys,mountaddr=192.168.1.3,mountvers=3,mountport=892,mountproto=udp,local_lock=none,addr=192.168.1.3)
192.168.1.3:/volume1/HERA on /media/julian/HERA type nfs
(rw,relatime,vers=3,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.1.3,mountvers=3,mountport=892,mountproto=udp,local_lock=none,addr=192.168.1.3)

This is the only difference I can see between the three: 
rsize=131072,wsize=131072, and timeo=600. Are these significant?

julian@Cerce ~ $ df -klh
Filesystem      Size  Used Avail Use% Mounted on
udev            3.9G     0  3.9G   0% /dev

tmpfs           799M   52K  799M   1% /run/user/1000

This is a bit odd as all three are currently mounted - Diana and Persephone at boot 
- albeit Hera is inaccessible via the mounted icon on the desktop.

Yes that works.

Kind Regards,
