You don't need to remount sheepfs even you have stopped the cluster. If
you ever want to remount it, you need to firstly umount the mount point. So
 $ sheepfs mountpoint # mount it
 $ umount mountpoint # unmount it

If you still have problems, would be great if you can give a script that
can reproduce the problem easily.

Thanks,
