if needed later, for unmount, for future reference

$ sudo umount /home/moodledata

configure mount when system boots, add additional line

$ sudo vi /etc/fstab
#added by Mehmet Sen
nfs:/home/moodledata /home/moodledata nfs defaults 0 0

$ sudo touch /var/moodledata/NFS.test

on server

$ ls -l /var/moodledata
