Nobuhito-san, GFS2 freezes I/O when it loses connection to a cluster node until fencing completes, which is probably what's keeping you from unmounting. And, you are running yourself into split brain from which you need to manually recover (assuming you haven't configured split brain autorecovery policies). Please take a look at Lon Hohberger's DRBD GFS cookbook http://sourceware.org/cluster/wiki/DRBD_Cookbook if the information in the DRBD User's Guide is not sufficient.
