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?


I was going to mention that, but also that while I’m sure that it’d handle power loss while it’s unmounted the filesystem I don’t know what happens if the backing storage goes away while it’s in use.
