This is well-known limit of current FFS. You need to use bigger
block size and/or frag size to get around this. You should be able to
have up to 4TB filesystem.

There appears to be some info regarding this on
	http://www.netbsd.org/Misc/features.html#large-filesystems
perhaps also elsewhere on NetBSD site.
