I’m running a Ubuntu server on my old laptop with an external HDD connected to it. The external HDD is powered independently from the laptop, as it is plugged into the wall.
During a power outage, my laptop remains operational due to its battery, but the HDD shuts down. When power is restored, my laptop does not automatically remount the HDD, and I have to reboot the system manually to access it.
Does anyone know how I can resolve this issue?
Edit: Not sure if this added context changes anything, but this is the HDD I’m using. It’s a 3.5" HDD that gets its power directly from the wall.


Wouldn’t that just mount the HDD when the server boots? I think the issue is re-mounting it while the server remains up, hence the systemd service. But maybe I don’t understand fstab fully.
I think you can use the service to remount using the fstab entries/options. (Like “mount /dev/disk/by-uuid/XXX” and it’ll automatically apply the options and mountpoint)
Arguably cleaner depending on your setup
I wanted to provide feedback for THIS part only. :) not for OPs issue. I would have responded to OPs post if that were the case…
