PVE will automatically wake up the USB HDD hard disk when it is shutdown


Apr 4, 2023
When the USB hard disk is sleep, turn off the PVE HOST, the USB hard disk will be woken up. After the shutdown is completed, the hard disk is still powered on and the disk is still rotating. I had to forcibly cut off the power of the hard disk.
I guess your Disk has a separate power supply? Is your Disk rotating if you only plug in power, but not USB? Does it go to standby in this case? Your Host can't handle the disks power modes anymore, if it is shutdown.

You can try to disable powering the USB Ports, when the Host is powered off, but you may lose the ability to start your Host by Keyboard. This option you can find in the BIOS if you're lucky.
Maybe an update to the disks/controllers firmware may help you.
Or you can try some Master/Slave socket, that cuts the power of the disk automatically, when the Host is off.
