I want to import my zpool's from FreeBSD 8.0 in OpenSolaris 2009.06.

The zpool import command is finding the wrong slices to import. Notice this says s8 for the last two slice numbers. It's also using s2 for the second disk, but s2 is typcally the entire disk anyway, so it's able to see all the data.

On the other hand, s8 is typically just the first cylinder -- just enough information for zfs to see the front labels, but not enough to see all the data.

zfs should probably be better about what it chooses for a disk to import. A coworker suggests looking at the zdb -l output, fdisk output, and prtvtoc output to see if there's a common theme that will lead to a solution independent of modifying zfs import code.
