OpenBSD and FreeBSD have a utility called
growfs See
http://www.freebsd.org/cgi/man.cgi?q...SD+9.0-RELEASE
Somebody ported this to NetBSD, but AFAIK it is not part of the NetBSD base system. NetBSD seemed to have had
resize_ffs but I cannot find much documentation about it.

BTW your problem would be more understandable if you would post your fdisk and disklabel output
