[b]Set up for test:[/b]
(I picked v8 for no particular reason.... this linux install can speak zfs v3
and zpool v13, as can our solaris b101 installs, but some of the older solaris
boxes we have can't I guess... so... I picked 8? I want to use this my little
500gb external ZFS disk. But first some testing!)
sdd is an external USB drive.

Hmm, thats weird? :(
Sol is actually a SunBlade 150 which prtdiag displays correctly, but for some
reason prtconf and uname display 100. *shrug*.
Any idea's why it can't import the pool on an external USB drive when intel can?
[b]Lets try a send/recv from sparc b101 to x86 (linux):[/b]
Couldn't do this since the sparc wouldn't import it.

Okay, so I forgot my livecd, its at home. Nevertheless, I assume it would work
since the previous test worked fine. So perhaps that bug was fixed in a recent
build?
So now a different question, why did the sparc fail to import my pool?
