Issues accessing Unraid shares from Debian 12 VM

I have created 4 shares in Unraid that I want to be able to always access from the Debian 12 VM.

In /etc/fstab, I have these lines:

//T440.local/linux /mnt/linux cifs rw,credentials=/etc/samba/servershare.conf,uid=1000 0 0
//T440.local/D /mnt/D cifs rw,credentials=/etc/samba/servershare.conf,uid=1000 0 0
//T440.local/e-i-root /mnt/e-i-root cifs rw,credentials=/etc/samba/servershare.conf,uid=1000 0 0
//T440.local/j /mnt/j cifs rw,credentials=/etc/samba/servershare.conf,uid=1000 0 0

These worked for a while, but then failed.

The result of the failure can be seen from the directories in /mnt:

ls: cannot open directory '.': Stale file handle
tim@sun-debian:/mnt/linux$ cd ..

tim@sun-debian:/mnt$ ls

ls: cannot access 'D': Resource temporarily unavailable
ls: cannot access 'linux': Stale file handle
D e-i-root j linux


I searched and got conflicting information on how to cause the system to re-load fstab and re-establish the shares.

mount -a

seemed to have no effect.

Another post in the article suggested "To refresh systemd’s view of the world, including changes to /etc/fstab, run

systemctl daemon-reload

This did not fix the problem.

I resorted to restarting the VM, and now the shares are operating normally again.

I would like to learn what I'm doing wrong and how to keep my mounted shares functional over time.
