Happend a few minutes later again, remade the usb stick, copied the contents of the old usb to the new usb, requested guid transfer from old usb to new usb guid and worked like a charm. system running again.
I do request that if this happends that the system is able to shut down properly? i was unable to stop the array/dockers/vms and made the system get a unclean shutdown. resulting in a parity check...
