What is the best way to shut down PPV4?

Hi,

I have read through various forum topic and I don't find any satisfying answer.

Can anybody confirm if poweroff or shutdown -t 10 will properly shut off the ppv4?
My biggest worry is that if I turn the main power off and on again, will I reboot will it boot up properly?
I tried once and in the end, the system was corrupt and somehow I could never ssh back into the device and I had to re-build everything from the scratch.

Now, my ppv4 device is running. I want to get some sure answer/step to swtich the power off properly.

Also when we want to unplug the connected usb drives, is there a way to unmount safely?

Powering off: systemctl poweroff
Unmounting: umount <drive>

Thanks for the reply. After poweroff command, how shall know that its safe to switch off the power supply?

The front LED goes off, and any attached drives will spin down.

Thanks again.

My problem is that earlier when I issued poweroff command, I waited for quite long for front LED to go off. But it never did though the HDD spinning has stopped.

I gave a try by swiching off the ppv4 device and switched on again. All I saw through SSH was some junk character

In the end, I tried to recover the OS but I failed and had to revert back to original firmware and do all over from the scratch.

Now the device is still running for 2 days. I don't know if i should shut it down at all if its not going to boot back safely after the switch off and on episode.
