Try the 9.2-BETA2 snapshot.

The 9.1-RELEASE (you did not provide any clear indication *which*
snapshot you tried) does not support zpool version >28.  9.2-BETA1 and
9.2-BETA2 snapshots do.

If you did update your zpool but not the zfs boot loader, you can fix
the loader by following the instructions in /usr/src/UPDATING,
specifically the "ZFS notes" section.
