	We should also add an o2info operation --mkfs.  It should output
mkfs.ocfs2 arguments that will duplicate the characteristics of the
specified volume.

# o2info --mkfs /dev/xxx
-N 2 -J size=128M --fs-features=sparse,unwritten,inline-data -C 4096 -b 4096

# mkfs -t ocfs2 $(o2info --mkfs /dev/xxx) /dev/yyy
