I went to login to unRAID this morning and couldn't connect.  I followed the ethernet wire to my Cisco switch and noticed the port wasn't lit up.  I logged into Cisco web portal and see 4 input errors on this port. I tried to move the wire to another port but nothing.  I checked the wire at the MB port and no wiggling would cause it to light up.  I switched my monitor to DVI in order to see the command line so I could shutdown but nothing would show up.  I then held down the power button to hard reboot and it wouldn't shut down until I unplugged the cable!!

 

All that said, is there any logs I can provide which might help somebody understand why the ethernet port and computer itself seemed to freeze up?  In the future, if I lost ethernet connection and could access the command line, is there a safe way to shutdown so that I don't have to run the parity check on 20+ TB of data?

If it even hasn't shut off when you have held down the power button for a couple of seconds, then you have a even more serious problem with your MoBo but just the ethernet connection.

If not even the chipset won't respond anymore, how can you expect that there is still a chance to log on and shutdown properly?

This is the first time the power button hasn't allowed a hard reset ... perhaps because I hit the soft reset button before holding the power button down, not sure.  In the past, the power button has worked to hard reset, but unfortunately this means a full scan when powering back up, thus the question, what command to perform a power down without needing a full scan on reboot and if unRAID logs would provide any insight into why the ethernet port and anything else would have stopped working.

The powerbutton is not depending on any os or bios. it is handled by its own, independent, microcomputer located within your chipset. So, if you hold it down for a longer period and nothing happens, means, your whole motherboard is dead and unresponsive. This should never happen.

 

And, I'm afraid, you cannot avoid the parity rebuild. I've read somewhere that there is a method to declare parity valid, but In your case it is surely not valid and would lead to false parity therefor corrupting real data-. Let it run and be patient.

FWIW - if you stop the array before reboot it will not do the parity check.  Obviously this should only be done if you're shutting down safely and not because of some failure.
