True to the intent of this list, David Schiffrin <>
responded very quickly with the the answer and the solution. Casper Dik
<casper@holland.Sun.COM> also correctly diagnosed the problem (as he
usually does, thank you for paying such regular attention to this list,

Due to a bug (Sun #1264428), Ultra1's can't use a 4096 block size. And
when I let the system use the 8192 default, everything actually worked.

Others (thanks folks, and my apologies if I missed anyone) reported that
they had successfully setup larger than 2G filesystems, and so there should
be an answer:
