When I issue zpool import, zpool command returns a message as if the pool was normal.

saturn ~ # zpool import
   pool: zpool
     id: 1358522578922881949
  state: ONLINE
 status: The pool is formatted using a legacy on-disk version.
 action: The pool can be imported using its name or numeric identifier, though
        some features will not be available without an explicit 'zpool upgrade'.
 config:

        zpool       ONLINE
          mirror-0  ONLINE
            sdi     ONLINE
            sda1    ONLINE

But, when I issue zpool import zpool, the command freeze and kernel print an error message.

saturn ~ # zpool import zpool # Freeze!
