Looks like a mail program tried to make a link.

If that will store the data in the large "'home" partition that shows
only 4% used, yes. But at this point I'm not sure what to do to correct
this, can I edit the /etc/exports file in the server directly. I assume
I will need to change fstab accordingly too.
Yes on all counts. We need to work on building your confidence by
showing you how to verify that each change you make is working as
expected.
On the server, I suggest you copy "/etc/exports" to "/etc/exports.new",
edit "/etc/exports.new" to make the change and post the .new file here
so others can check for problems. Once you are confident that the
changes are good, you can use "showmount -e" to record the
current state, then, on the client, unmount the server so you can
make the change:
On the client, unmount all nfs filesystems:
step 0. sudo umount -a -t nfs
Back on the server, you need to stop exporting the old directory,:
step 0: sudo exportfs -u
"/nfs_share/home"
then move the data from "/nfs_share/home" to "/home/nfs_share":
step 1: sudo mv /nfs_share/home /home/nfs_share
systemctl daemon-reload
Check that /nfs_share is empty, that /home/nfs_share
has the expected contents, and that the root partition has gained
roughly the same space that has been lost on the /hom
Check that /nfs_share is empty and that /home/nfs_share
has the expected contents.
Update "/etc/exports", and export the new "/home/nfs_share":
step 2. sudo mv /etc/exports /etc/exports.old
step 3. sudo mv /etc/exports.new /etc/exports
step 4: sudo exportfs -av
Verify that this worked by running "showmount -e"
Back on the client, make a "/etc/fstab.new" with the same process and post
for review. The version you posted earlier seems to have a typo, but that may
have occurred when posting.
Once you are confident in your fstab, replace the original version with the updated
version
step 5: sudo mv /etc/fstab /etc/fstab.old
step 6: sudo mv /etc/fstab.new /etc/fstab
Then let systemd know about the changes:
step 7: sudo systemctl daemon-reload
step 8:
e partitionby running "df -lh / /home"
Update "/etc/exports", and export the new "/home/nfs_share":
step 2. sudo mv /etc/exports /etc/exports.old
step 3. sudo mv /etc/exports.new /etc/exports
step 4: sudo exportfs -av
Verify that this worked by running "showmount -e"

step 6: sudo mv /etc/fstab.new /etc/fstab
Then let systemd know about the changes:
step 7: sudo systemctl daemon-reload
Verify that the changes are working: the contents of "/media/nfs"
should look the same as they did before the server ran out of space
on the root partition.
