Mounting does nothing

no drive is mounted, yet no error is thrown
  •  1 min  •  

I recently encountered an odd issue when trying to mount an external drive. When I ran sudo mount /dev/sdb1 /media/Drive or sudo mount -a with the appropriate configuration in /etc/fstab, nothing would happen. The drive was not mounted, /media/Drive would be empty, yet no warning or error was displayed.

Completely unmounting and remounting the drive did not help. The drive was already unmounted.

It was reloading the systemd process that solved this for me:

systemctl daemon-reload
systemctl daemon-reexec
