From 'man newfs':

     -O filesystem-format
                 Select the filesystem-format.
                       0    4.3BSD; This option is primarily used to build
                            root file systems that can be understood by older
                            boot ROMs.  This generates an FFSv1 file system
                            with level 1 format.
                       1    FFSv1; normal Fast File System, level 4 format.
                            Also known as `FFS', `UFS', or `UFS1'.  This is
                            the default.
                       2    FFSv2; enhanced Fast File System, suited for more
                            than 1 Terabyte capacity.  This is also known as
                            `UFS2'.

HTH,
