No doubt. Russia placed too much faith in the OSCE and France and Germany approaching the process in good faith. Merkel later came out and said that the Minsk process was just a time-buying exercise so that NATO could arm Ukraine as a proxy against Russia.
Ukraine, of course, knew that it was being armed and trained and had the carrot of NATO and EU membership dangled before it. Circling back to the original point, the fact that Ukraine was being armed and trained at such a rate is good evidence that Ukraine absolutely knew what was about to happen.
