Nope, looks fine to me :)
This is a mirrored vinum volume created from 2 partitions fully taking 
up 2 73gb drives.  vinum shows this as 68gb volume, which I guess is 
ok considering kbmbgb calculation rip-off, but losing 10gb after 
newfsing is something new. The only other thing I did is turn on soft 
updates, but I wouldn't expect that too 'steal' 10 gb also. anyone  ?
5gb :)
UFS keep x% of the drive unavailable from anyone but root as part of the
filesystem optimisations, you can turn this off if you want with tunefs
but expect a performance hit from it.

While the question in this FAQ isn't the same question you're asking,
the answer is the same:

thanx guys. learn something new every day.
I actually noticed that my smaller volumes display the
same 'discrepancy'..., but it only became a concern after
'loosing' 10gb :). hehe.
should've realized that myself right away.
is this true though that soft updates use additional disk space ??

No, that's not true.  Where did you hear that?

No, softupdates are just a different way of handling writes iirc, they 
dont have any space overheads afaik :)
