How can I understand that volume stopped if in "<span class="">gluster

Not a bug. If `volume info ` says it is started and `gluster volume
status` shows gluster processes as offline, it means something is
wrong and needs investigation. In your case you need to see why the
other node is down. Having identified the second node is down and
cannot be brought back anytime soon, the `volume start force` is
just a workaround to restart the gluster processes.<br>

didn't changed output of "gluster volume info" but I
have mounted my share!<br>

In this case glusterd stops the brick processes but
doesn't mark its status as stopped.</p>
