[OpenIndiana-discuss] fuiture small expansion of raidz1 possible?

[Hans J. Albertsson]

The reason I wrote te below is not that I'm totally daft, I know ZFS 
could have had expandability for any vdev included, but didn't. But I 
read this piece on Expand-O-Matic ZFS (a dream of a future ZFS property) 
by Adam Lewenthal (sp??), written in 2008. And I really just wonder if 
it happened somewhere, somehow.
