Could this be correct for ad6s1 and ad7s1? they are about 20G
each
a: 9216000 14966784 vinum 2048 16384 28552

The only downside that i see from reading "The Vinum Volume
Manager" is that startup and shutdown will take longer, but I
don't see that being much more than a once a month activity at
the most. 1-200 days will be a much more frequent time between
booting for this system.
