I'm not sure if this is a bug or if I'm doing something wrong. I am trying to
create a zpool which can be mounted either locally or over iscsi. For testing I
have created a local zvol, and then create a zpool on top of the zvol. That
seems to work OK. When I try to import the same zvol over iscsi, I get the
"value too large" error below. This happened on both 2008.5 and Nevada build 97.
