I have a NAS, which is running for many years without a monitor, keyboard and mouse. Today, I connected them and check the hardware and flash the BIOS from 1.30 to 1.50. The motherboard is AsRock J3160-ITX.
Suddenly I noticed an error during the POST, and booting.
The error is reading:
A Start Job is running for dev-nas2-middleone.device.
I remembered that I have removed the second HDD from the NAS. It is named as “middleone”.
So I solve this problem in the terminal screen.
