Hi I setup my unraid HTPC and installed Plex to run at startup. unplugged everything and brought to my sons as it was for him. when I got it there it would not recognize the usb. I checked bios settings, no bios features were changed. So I removed usb and ran Mac.exe file on it again and then it worked. Will I have to do this if it looses power again?

Normally no. If you didn’t shut down unRAID properly it can happen. Another words if you didn’t use the GUI and shut it down it could happen. If you just held down the power and pulled the cord if could very well happen. 

So I should always use GUI to shutdown and or setup timers with dynamix sleep?

what if house power goes out? Will I need to reset USB again?

If your UPS is properly set up, it should automatically power down safely. If it doesn't, then set the power down delay lower, I have mine set to shut down after the power has been out for 5 minutes.

But is the OP actually using a UPS?

 

Anyway - a power loss without a UPS should normally not introduce any issues with the USB thumb drive. It should normally just result in a need to resync the parity drive.

Probably not, but perhaps I was trying to make a point.

Hey guys I’m still having issues with my unraid setup. I used the web UI to shut down my system and then when I turned it back on the next day it wouldn’t boot into the OS. I have bios updated and set to only run from USB. I’m using a USB drive with an Asus Q87T slim itx motherboard in a perfect home theatre case. Any help would be appreciated

Try a different flash drive.
